Analysis of common problems in quality management of front spinning in cotton spinning enterprises 2020/10/30

At present, the spinning equipment of Chinese enterprises is becoming more and more advanced, but the quality of many enterprises is difficult to improve. There are many reasons. A brief analysis of the quality problems is mainly related to raw materials, equipment, technology, air conditioning, management, etc., but Inadequate simple management is also an important reason why the quality is difficult to achieve the desired quality. This article simply analyzes the problems in daily management and puts forward suggestions for rectification, which have certain reference value for improving yarn quality and reducing yarn defects.In terms of raw cotton management, many companies currently do not have enough reserves, resulting in inadequate batches of raw cotton and excessively large batches, resulting in yarn color problems. The amount of cotton reserves must match the amount of production used, so that batches can be received normally. At the same time, it is necessary to strictly control the raw cotton purchase. Some raw cotton is processed, although it feels better, but it has very poor spinnability. Table 1 is the AFIS test data of two batches of real estate cotton used by a domestic cotton spinning factory. The two cotton samples have no obvious difference in hand feel, but it can be seen from the AFIS test data that there are obvious differences in quality indicators. Although the purchase price of sample 2 may be lower than that of sample 1, its high lint rate and high neps will directly affect the quality of yarn.The outer side of the raw cotton is mildewed or the incidental debris is not cleaned up. Although most of the blow-up and carding units are now equipped with complete foreign fiber removal machines and trash removal systems, they cannot eliminate such dirty flowers and impurities 100%.Some enterprises do not manage the use of reeling in place, which affects the quality of the finished yarn. The general principle for the use of re-spending in spinning mills is: for ordinary ring carded yarn, the recycle ratio generally does not exceed 5%, and the recycle of combed yarn The use ratio should not exceed 2.5%, and in the process of use, pay attention to the packing density and placement of the return sliver. The packing density of the return sliver should be close to or consistent with the density of the bale. The return sliver must be torn off before returning. It is recommended that the length of the tear is less than 30cm. However, some companies cannot strictly limit the actual use process, and control the amount of recycling according to the amount of recycling generated, and how much is used, resulting in inconsistent recycling ratios between disks, and even the quality of recycling is difficult to guarantee, such as recycling. It contains a lot of cords, and the return sliver is not broken, which has a great impact on the quality of the yarn.One of the reasons for the lack of ingredients to grab cotton is the inconsistent height of the pack. Now the domestic Xinjiang cotton, especially the northern Xinjiang cotton and southern Xinjiang cotton, the regain of raw cotton is very different. The maximum regain of raw cotton can reach more than 10%, and the minimum is less than 6%. This causes serious inconsistency in the degree of bale increase after raw cotton is discharged. Afterwards, the production was started without flat bales, resulting in a lack of ingredients to catch cotton. Another reason is that the recycled recycles and slivers are not packaged, and are scattered directly in the overlock, resulting in a lack of ingredients and spinning.Raw cotton management is the first step in quality management. These problems in the management and use of raw cotton are important issues to be solved in quality management.......

Seize opportunities in the international market to consolidate export competitiveness 2020/10/30

In the face of major changes in the internal and external development environment, the central government proposed to "gradually form a new development pattern with the domestic cycle as the main body and the domestic and international dual cycles promoting each other." This is a strategy for strengthening the country proposed at the critical stage of China's economic development towards high-quality development. It is necessary to accelerate the formation of a virtuous circle of internal and external development with a higher level of opening up. The textile industry has also ushered in new opportunities for transformation and development with domestic demand as the guidance and supply-side structural reform as the main line.　　 The textile industry is one of the earliest and most market-oriented industries in my country. As we all know, the Chinese textile industry has actively participated in the development of globalization in the past few decades, used its comparative advantages to meet the needs of both domestic and foreign markets, gradually cultivated its own brands and technologies, and continuously improved the added value of products. After years of development, the textile industry has taken the lead in the world. Position, become the industry with the largest production scale, the most complete industrial chain, and the most complete categories, basically achieving the goal of a textile powerhouse. Following the market orientation, textile companies continue to explore both domestic and international markets, and under the market leadership, actively promote transformation and upgrading, adjust the industrial structure, and the proportion of domestic sales continues to increase. Expanding the domestic market and stabilizing the export share is the direction of the development of textile industry enterprises.　　Under the current situation, stabilizing the export share is of positive significance to the "six stability" work proposed by the Party Central Committee and the State Council. This year, under the influence of the new crown epidemic, international demand has been hit hard, but in the post-epidemic era, the degree of recovery of international demand and the adjustment of China's role in the global textile supply chain have become a key impact on the stable exports of my country's textile industry.　　 International clothing demand "basic plate" is still　　How to look at the "basic disk" of international demand for textile and apparel? Taking clothing as an example is a better entry point. Although clothing is a non-fast-moving consumer product and has the attribute of postponing consumption of non-essential goods, as a rigid demand product for final consumption by the masses, as long as the population continues to grow and people's yearning for a better life exists, the "basic disk" of international demand will not There are fundamental changes.　　 According to the global import clothing data released by the WTO, in 2000, global clothing imports were US$203.099 billion, which increased to US$527.130 billion in 2018, an average annual increase of 5.44%. The scale of global clothing consumption continues to expand. The United States, the European Union, and Japan accounted for 83.7% of global apparel imports in 2000, and this proportion fell to 64.7% in 2018. Although the proportion has declined, the United States, Europe, and Japan are still the main markets for global clothing consumption.　　 Let's analyze the changes in clothing consumption from the clothing imports of Japan, the United States, and the European Union in the past 20 years.From 2000 to 2019, the average annual growth rate of Japan's global imports of clothing reached 2.21%, and the "big market" of clothing consumption also rose from 2.12 trillion yen in 2000 to the highest point of 3.42 trillion yen in 2015, and to 2019 It remained at a scale level of more than 3.20 trillion yen. Although the growth rate has been high or low, and even showed negative growth for several years, from a linear trend, the "basic disk" of Japanese clothing import consumption has been expanding continuously in the past 20 years.From the perspective of U.S. clothing imports, from 2000 to 2019, the U.S.’s global imports of clothing increased by an average annual rate of 2.03%, and the “market” of clothing consumption rose from USD 57.232 billion in 2000 to USD 85.151 billion in 2015. Maintain the import scale of 83.823 billion U.S. dollars in 2019. From a linear trend, the "basic market" of US imported clothing is also slowly increasing.　　 From the perspective of EU clothing imports, from 2002 to 2019, the EU’s global imports of clothing increased by an average annual rate of 5.00%. The clothing consumption "big market" rose from 37.038 billion euros in 2000 to 84.927 billion euros in 2019. From the linear trend, the “basic” slope of EU imports of clothing exceeds that of the United States and Japan.　　 It can be seen that although the annual growth of clothing imports in the three major markets has been high and low over the past 20 years, sometimes there has been a negative growth, and even affected by the global financial crisis, the decline in clothing imports in 2009 was still deep. At this stage, affected by the epidemic, the clothing import demand of the United States, the European Union, and Japan has also shown a shrinking trend. But from the long-term trend, the "basic disk" of clothing demand in the three major markets still exists.　　 my country's garment exports are under increasing pressure　　 my country is the largest country in textile production and export. Although in recent years, due to the increase in the cost of labor and other factors, some of my country’s textile production capacity has shifted to Southeast Asia and other regions, but limited by the production volume, supporting capacity and rising labor factor costs in Southeast Asia, we want to shake up the development of my country’s textile industry. Global status is difficult to achieve in the short term.　　 However, in recent years, the share of my country's clothing exports in the main international consumer markets has shown a declining trend.　　 From the perspective of Japan’s clothing imports in the past 10 years, my country’s clothing accounted for 82.2% of the Japanese import market in 2010. By 2019, this percentage had fallen to 55.9%, a drop of 26.3 percentage points. This part of the market share is mainly shared by Southeast and South Asian countries such as Vietnam, Bangladesh, Cambodia, and Indonesia. From January to August this year, my country's apparel market share in Japan further dropped to 53.4%, indicating that my country's apparel exports to Japan have increased.　　 The U.S. market is constantly pursuing high-quality and low-cost apparel products, and the market is highly diversified. In 2010, my country's apparel accounted for 39.2% of the U.S. import market. By 2019, this proportion dropped to 29.7%, a decrease of 9.5%. From January to August this year, my country's apparel import market share in Japan further dropped to 22.7%, indicating that my country's apparel exports to the United States are facing greater pressure.　　 From the perspective of clothing imports in the 27 EU countries in the past ten years, in 2010, my country’s clothing accounted for 43.8% of the EU’s import market. By 2019, this proportion had dropped to 29.5%, a drop of 14.3 percentage points. From January to June this year, the share of my country’s clothing in the EU’s import market rose slightly, reaching 30.4%, an increase of 0.9%, but this is the first half of this year. As the epidemic continues in Europe, pressure on my country’s clothing exports to the EU market is still unacceptable Underestimate.　　 Improve the status of international circulation with higher quality　　 Affected by the global epidemic, the world economy is in recession, the circulation of the industrial chain and the supply chain is blocked, and the export of my country's textile industry is also facing challenges. On the supply side, the "low cost" advantage of my country's textile industry is gradually weakening. How to increase the added value in the international cycle is an important issue that needs to be resolved. In terms of demand, the main export markets of my country’s textile products are Europe and the United States. However, due to the sharp decline in international trade demand, economic globalization has encountered a countercurrent, protectionism and unilateralism have increased, and uncertainty and instability have significantly increased. The demand for our textile products may shift and shrink. How to stabilize and expand the market is another important challenge facing my country's textile industry.　　 Faced with the new situation and new challenges, the industry needs to actively explore a transformation and upgrade path to enhance the ability to meet domestic demand as the main line while enhancing the status of the international cycle.　　 From product design, raw material supply to processing, production and consumption circulation, China’s textile industry is highly international in every link of the industrial chain, and is an important component of global value chain cooperation and industrial transfer. This determines that the industry can only achieve the optimal allocation of resources and achieve better development only by integrating into the world trend. In the current complex international political and economic situation, the industry must unswervingly use more in-depth international cooperation to oppose geopolitical de-globalization. Further deepen international cooperation in production capacity, and bring benefits to more countries’ economic development and people’s lives in open development; further strengthen cooperation with international brands, continuously integrate new resources and open up new markets in a mutually beneficial and win-win situation; further strengthen cooperation with international organizations Cooperation, reach understanding and consensus in communication and coordination, and strive for more space for the industry.......

The shortage of raw materials affects the implementation of the Vietnam-EU Free Trade Agreement 2020/9/25

According to a report from Vietnam's "Vietnam News" on September 22: Vietnam-EU Free Trade Agreement (EVFTA) rules of origin limit the source of raw materials for companies. Experts say that in order to seize the opportunity to export to the EU, Vietnamese textile and clothing companies must overcome the obstacle of shortage of raw materials.　　 According to data from the Ministry of Industry and Trade of Vietnam, the EU has a huge demand for textiles and clothing, with an annual import value of approximately US$250 billion. Vietnam’s exports to the EU in 2019 amounted to US$4.3 billion, an increase of 3.8% year-on-year, accounting for only 2% of the EU market. The Ministry of Industry and Trade stated that the EVFTA, which will take effect from August 2020, is expected to help Vietnam's textile and garment industry to increase exports to the EU by 67% by 2025. However, according to EVFTA's commitment, in addition to meeting strict quality standards and enjoying preferential tariffs, local companies must also implement strict origin requirements, especially the origin rules from the fabric link, which means that products exported to the EU must be used Fabrics produced in Vietnam or the European Union. The agreement also allows the use of raw materials from Vietnam and the EU's joint free trade partners. This has become a weakness of the Vietnamese textile and garment industry, as most of the raw materials are imported from countries that have not yet signed a free trade agreement with the European Union.　　Vo De Jiang, chairman of the Vietnam Textile and Apparel Association, said that local textile and apparel manufacturers should use domestic raw materials in the production of products for export to the EU, but in fact many people do not know the source of the raw materials. In addition, new-generation FTAs such as the Comprehensive and Progressive Trans-Pacific Partnership Agreement (CPTPP) and EVFTA have very strict regulations on materials and manufacturing processes.　　 The relevant negotiating experts in Vietnam believe that to solve this problem, the textile and apparel industry can use fabrics imported from countries that have signed FTAs with the EU, such as South Korea, to enjoy the preferential EVFTA tax rate. However, due to distance and price, the quantity of fabrics imported from Korea is very small. In the long run, Vietnam needs a comprehensive strategy to seize opportunities in the EU market. A clothing company said that in order to meet the EVFTA origin requirements, the company has signed a contract to import raw materials from EU free trade partners such as South Korea and Turkey instead of buying from China.In addition, the Ministry of Industry and Trade is formulating a development plan for the textile and apparel industry to develop a large-scale textile and printing and dyeing industrial park with a wastewater treatment system that meets international standards by 2040 to attract investors and create a textile-dyeing-clothing cycle. This will help Vietnam’s domestic textile and apparel industry to join the global supply chain, reduce dependence on imported materials, and make full use of EVFTA and other free trade agreements.......

Selection of heating method for polypropylene spinning machine 2020/9/25

In the energy-saving transformation of electromagnetic heating, there is a new industry that can make good use of electromagnetic heaters, that is, the textile machinery industry. This industry has a polypropylene spinning machine, which has different types: polypropylene FDY spinning machine, polypropylene FDY spinning machine , Polypropylene POY spinning machine, polyester FDY spinning machine, polyester FDY spinning machine, polyester POY spinning machine, polypropylene BCF spinning machine, etc.This type of machine has one of the most important components called the heat roller, which needs to be heated to a certain temperature and runs at high speed. The size of the heat roller is different, generally there are diameters Φ160 Φ180 Φ190 Φ210 Φ220. Length of hot roller: 200-450mm, speed range: 750-5500m/min, surface temperature of godet: ≤240℃-140℃, surface treatment of hot roller: hard chrome plating, ceramic plating.The current heating method of the heat roller is power frequency induction heating. Its disadvantage is that the heating ring is easily damaged. The most terrible thing is that it is easy to heat the central shaft of the motor and burn the motor. Shenzhen Xinhuiyuan's newly developed all-digital application is applied to the heating of polypropylene textile machines with high efficiency and energy saving, which completely solves the shortcomings of traditional heating and greatly reduces the cost for customers. The main advantages of using Xinhuiyuan electromagnetic heater for the heat roller are:1. Make the surface temperature of the hot roller work area uniform, which can meet the requirements of different industrial yarns and civil yarns FDY spinning process2. The surface temperature of the working area of the hot roller rises rapidly, energy saving is obvious, and the efficiency is greatly improved3. After using the electromagnetic heater, the shaft of the heat roller motor will not damage the motor due to induction heating4. The coil of the electromagnetic heater will not be damaged, reducing maintenance trouble and cost5. The equipment has a complete system, simple structure, stable and reliable operation at high temperatures, and can meet the requirements of different fiber FDY spinning processes. It is an economical and reasonable choice for polypropylene FDY spinning.......

The marketing of nylon/cotton fabrics in autumn is smooth 2020/9/18

Recently, orders for autumn nylon/cotton fabrics in China textile city market have increased. The marketing of autumn cotton and nylon fabrics has expanded compared with the previous period. Fabrics with creative styles have been favored by customers from the north and south of the secondary market and purchasers of apparel manufacturers. Local marketing is relatively smooth and has become a marketing highlight.Recently, the start of terminal weaving has shown a slight increase. The comprehensive operating rate of chemical fiber weaving in Jiangsu and Zhejiang is 69.36%, which is still at a relatively low load compared to previous years. The predicament of conventional grey cloth products has been heard and seen by all textile people. It can be said that all kinds of inventory backlogs and shrinking profits have been at the peak of history. However, there are few methods to adjust production strategies and change production varieties in the market, and there are still relatively many textile people who are unwilling to make breakthroughs in conventional products.The textile industry has experienced an off-season that has not been seen in many years, and all production links and various conventional fabrics have encountered sales declines and shrinking profits. But among all the products, the most troubled and most confused in the future may be the very common conventional fabrics on the market. Although the market is not good, there are still many hot-selling products, but these products have nothing to do with conventional fabrics. In order to receive orders, it is normal for the market to allow arrears, but risks coexist. Some new customers may use quality problems to find reasons to deduct the payment. For this reason, many fabric manufacturers have raised the threshold for cooperation with new customers, and even some companies only cooperate with old customers under the current market conditions. Although the return rate of old customers is slow, they generally do not deduct the payment for no reason. The sadness of conventional fabrics can be seen more or less by textile people. The export of clothing and textiles has been blocked this year, especially the resistance to clothing exports. It is unknown whether subsequent orders will continue. Most companies are also actively looking for new growth points, and the development of new fabrics is urgent.In the recent market, orders for autumn nylon/cotton fabrics have been enthusiastically placed, and orders for nylon/cotton leisure fabrics have increased. With 150D nylon yarn×21S/C double-weft nylon/cotton fashion cloth, 150D nylon yarn×32S/C nylon/cotton imitation Tencel fashion cloth, the bureaus, departments and cities also have flat-panel dyeing as the leading products, and each has small batches and multiple batches. Spot transactions and orders are sent out in the same department. The domestic market orders for autumn nylon/cotton fashion fabrics and nylon/cotton leisure fabrics have increased partially, and orders received are small and medium-sized, and the orders placed by counterparts in the market have increased partially. 32S/C×100D nylon yarn + 40D spandex yarn nylon cotton weft elastic Medium-thick autumn fabrics, 32S/C×140D nylon silk +40D spandex silk nylon cotton weft elastic satin medium-thick autumn fabrics, because of the hand feeling and quality better than other varieties, it has been widely ordered by domestic apparel manufacturers for many days. Some foreign trade company salespersons also have small and medium-sized batches of sample orders, and the number of counterparty customers entering the market has also increased in batches. Some front-shop and back-factory cloth companies, production enterprise marketing departments and large-scale sales outlets have marketing advantages, and Chinese and foreign orders are accepted. Increase accordingly.In the recent China textile city market, the sales of autumn nylon/cotton fabrics have been relatively active, and the orders for counterpart fabrics have increased, and the sales of new creative fabrics have increased. Both fashionable and casual autumn nylon/cotton fabrics, cotton/nylon fabrics, and spandex-added nylon/cotton stretch fabrics, and cotton/nylon stretch fabrics have relatively smooth transactions. Nylon/cotton coated fabrics and nylon/cotton plus metal wire memory fashion Cloth, nylon/cotton plus metal wire imitation memory fashion cloth, small batches of multiple varieties, local transactions also went smoothly.The above-mentioned autumn nylon/cotton fashion fabrics and nylon/cotton leisure fabrics, in addition to flat dyeing, also have PU, PA, PVC coated fabrics and coated composite fabrics due to their novel styles and creativity. Relatively large, daily order transactions have also risen slightly. Some cloth companies with shop fronts and factories behind, production business operators, and large-scale sales outlets, and the buyers of the corresponding apparel manufacturers are more active in placing orders for multiple varieties, and creative fabrics are added. The value is still higher than that of large-scale products. Part of the autumn medium-thick new nylon/cotton fashion fabrics are also favored by target customers. Local small batches of multiple varieties have also been traded smoothly. The marketing highlights of autumn nylon/cotton fabrics have partially appeared.......

With the advent of "Golden Nine", weaving, dyeing, and finishing are short of people! 2020/9/11

With the deepening of the "Golden Nine", the textile market seems to have undergone a great change. The voice of the market is no longer dominated by "decreasing prices and selling goods", but there have been long-lost price increases, dyes and dyeing fees. , Grey cloth, etc. have risen to a certain extent. In addition to the above price increase information, there have been some subtle changes in the textile market compared to the first half of the year!In the first half of this year, due to the impact of the epidemic, foreign trade orders have almost stagnated, and domestic orders have been few. Many textile mills are in a situation of "nothing to do". In the dyeing factory, the average operating rate of the dye vat in the first half of the year was only half, and workers often gathered to chat. Faced with this situation, many cloth owners have also taken some measures. At that time, it was frequently reported that weaving factories, dyeing factories, and trading companies had dismissed many workers at once. But by September, some factories had begun to recruit workers again. What are the reasons for such a big change? I understand that most of the recruiters are weaving factories that had high temperature and long holidays before. When the long holidays were over, they found that some workers had returned to their hometowns for employment, and some had already found jobs in other places, which also led to some jobs. Gaps, so began to recruit people. There are also dyeing factories and finishing factories. A person in charge of the dyeing factory said: “Recently, due to the increase in work, our machines have been fully operational. We previously fired some workers because of fewer orders, but now we find It’s not enough. In order to keep up with the production schedule, we have to recruit workers again."Want to keep the workers by raising wages, but Boss has more than enough energy to keep it!Of course, some people say that workers can be retained by raising wages, but for the textile bosses, it is really too much and insufficient. This year, many weaving factories are operating at a loss, with only expenditures but no income, and some are out. You may not get the payment. Based on these reasons, some small factories with insufficient strength are simply unable to raise wages for their workers. "Now all costs are rising, including rent, water and electricity, and safety supervision. Workers also have high wage requirements. The wages of a worker in the factory are nearly 10,000 yuan, so every month it requires hundreds of thousands of funds. However, in terms of orders, the prices given by customers are very low. Now some orders can make a few cents of profit, and some take orders at a loss. This year's market, we can feed the workers and we are satisfied." A factory owner with about 40 people said .Judging from some of the above micro-circumstances, the market in September has indeed improved, but how long this wave of market can continue to improve remains to be verified by time. And when the market does not improve significantly, the loss of workers next year may become more serious, and textile bosses need to take precautions in advance!......

Apparel industry destocking half-year net profit fell by more than 30% 2020/9/4

The first half of this year was a difficult period for the textile and apparel industry.　　According to the National Bureau of Statistics, the total retail sales of textiles and apparel from January to July was 595.9 billion yuan, a year-on-year decrease of 17.5%, which was 7.6 percentage points lower than the growth rate of retail sales of consumer goods in the same period.　　 This also fully shows that, compared with rigid demand products such as food and household appliances, the textile and apparel industry lacks rigid demand during the epidemic, which has led to a historically rare setback in market demand. Especially in the clothing industry, market competition is already fierce. Under the influence of the epidemic, offline sales of clothing are at risk, and it is difficult for big brands to stand alone.　　 A quarter of the company lost money, and overall profits fell by more than 30% year-on-year　　 In the A-share and Hong Kong stock markets, there are a total of more than 100 textile and apparel-related listed companies.　　 Among them, there are a total of 82 textile and apparel companies in A shares, and all of them have disclosed the 2020 semi-annual report. In the Hong Kong stock market, there are a total of more than 20 textile and apparel companies, and currently 17 companies have also disclosed semi-annual reports.Judging from the semi-annual reports of the 99 textile and apparel companies, almost all of these companies were losers in the first half of the year. Net profits were cut in half, losses expanded, a large number of stores were forced to close, and subsidiaries were sold to survive, etc., which outlines that the entire industry is experiencing years of misfortune. Horrible situation.According to Wind data, in the first half of 2020, the 99 companies achieved a total revenue of 203.1 billion yuan, a decrease of 20.97% from the 257 billion yuan in the same period last year; a cumulative net profit of 12.17 billion yuan, a decrease from 18.429 billion yuan in the same period last year 34%. Both the decline in revenue and net profit means that the market size of the entire industry has declined to a greater extent. Some experts predict that the overall apparel industry will reduce revenue by at least 400 billion yuan this year, and the overall market size will shrink by 15%.　　 In the first half of the year, only 25 companies in A-share and Hong Kong stock textile and apparel companies achieved net profit growth. In other words, more than 3/4 of the 99 companies in the two markets experienced a decline in net profit in the first half of this year.　　 Regarding loss-making companies, a total of 25 companies incurred losses in the first half of this year, accounting for more than a quarter of the entire sector. Among them, urban beauty (02298-HK), Giordano International (007019-HK), Shinur (002485-CN) and Sanfu Outdoor (002780-CN) and many other companies turned from profit to loss during the period. The obvious similarity is that it relies on offline income and has gradually declined in the market where competition has intensified in the past few years.From the perspective of the entire industry, since the market has long been saturated and the incremental space is limited, small and medium-sized companies, including many listed companies, face market share being squeezed by leading companies, rising production costs, and unsmooth transformation tracks. Coming down. The capital market does not seem to be optimistic about the entire industry. The Flush Shun A-share Apparel Home Textile Index has been dropping from the high point in early 2017, and the cumulative decline has reached 41.5% so far, which is close to half. Together with the Shanghai Index, which has a 9.95% increase, it failed to outperform. .　　 Polarization of head companies　　 Thirty-six rows, all the best. Although the future growth of the industry has encountered a ceiling, this does not stop the leading companies that have the right to speak in the subdivisions. Of course, the sudden epidemic has also disrupted the operations of some leading companies in sub-sectors, causing disruptions in business performance.　　 The current subdivision of the apparel industry can be divided into men's wear, women's wear, children's wear, footwear and sportswear. In the steadily growing apparel industry, different segments show significant market differentiation. In the past few years, sportswear has recovered rapidly from the trough. Children's wear has maintained a high growth trend for many years. The mass leisure sector has grown steadily. The footwear market has experienced a process of decline to recovery, while the growth rate of menswear and womenswear has declined more significantly.In the above-mentioned segmented markets, each has its own leading companies. In the above order, the leading companies in each field can be listed as: Anta Sports (02020-HK), Semir Clothing (002563-CN), Semir Clothing, Aokang International (603001-CN), Hailan Home (600398-CN) and Winner Fashion (03709-HK), among which Semir Apparel is relatively strong and are leading companies in the children's wear and leisure sectors. Among these five companies representing various segments, the black swan of the epidemic also caused the business performance of these leading companies to diverge in the first half of the year.　　 It can be seen from the above figure that among the leaders in each segment, the performance polarization is very obvious. Among them, the leading sportswear leader Anta and the leading winner of women's clothing are the most resistant. In the first half of 2020, when the epidemic is critically hit, the performance decline rate has been reduced to a low level. In the first half of the year, Anta's revenue fell by only 1% year-on-year to 14.67 billion yuan, far surpassing other companies, and its net profit fell by 20.1% to 2.38 billion yuan, mainly due to the flexibility of the credit period strategy given to distributors, resulting in trade receivables Increase in loss provision. The high prosperity of sportswear has not been greatly affected during the epidemic. As the market leader, Anta has achieved significant results in its strategic adjustments in the first half of the year. It has promoted rapid online and offline integration through full retail, e-commerce live broadcast, celebrity sales, and KOL planting. Innovative marketing methods, as well as major marketing events such as the release of national flag Olympic licensed products, have successfully driven the increase in sales.In addition to Anta, sportswear companies such as Li Ning (02331-HK) and 361 Degrees (01361-HK) have not seen a significant decline in their performance in the first half of the year, and are controlled within 20%, which shows the anti-risk brought by the high industry boom The importance of.　　 Winner Fashion was formerly known as Koletier, which is well-known to the public, and it vigorously increased its online channels in the first half of the year and achieved good results. In the first half of the year, the revenue generated by the Winner Fashion Tmall e-commerce platform and the Vipshop e-commerce platform increased by 48.07% and 232.45% respectively year-on-year. The combined revenue of the two platforms further increased to 265 million yuan in the first half.　　 These two companies have something in common. They are both large-scale leaders in subdivisions. During the epidemic, offline and online integration was quite successful, and they performed well in opening up inventory in various fields. Both focus on the development of multi-brand and omni-channel. Anta has launched a "single focus, multi-brand, omni-channel" strategy. At present, it has ANTA, FILA, Descente (Descente, ice and snow sports equipment), Sprandi (strike shoes) The brand matrix, all direct sales models have become effective growth channels. The high-end women's clothing market in which Winner Fashion is located is fragmented, leaving a lot of room for development. Its brand matrix is rich. The sales scale of its main brands, Keletier and Naersi, are among the top ten in the industry. We all know that high-end women's clothing under the epidemic The market is not as sluggish as the low-end brands.　　 Semir Apparel, Hailan Home and Aokang International have difficulty in reversing the unfavorable situation in the market under the epidemic, and their results on online channels are not conspicuous. Among them, Hailan Home’s rapid expansion has many financial indicators behind it. In the first half of the year, the inventory reached 8.2 billion "topping"; Semir apparel’s overseas business was hit hard, and it announced the sale of 100% of its wholly-owned loss-making subsidiary French SofizaSAS to reduce the company’s operating risks.　　The epidemic forces industry changes　　 At present, many clothing stores in China have outdated product images, single service functions, and business conditions are deteriorating, and store leases have become the norm.　　 Behind this situation is the epitome of the decline of offline clothing stores in the past few years. Many companies are also looking for the direction of transformation, but under the pressure of operating costs and business model exploration, the transformation effect of the entire industry is not ideal. On the one hand, it is not easy to get through online and offline integration, which requires a lot of money and time to verify; on the other hand, many companies stick to a single category and lack innovative thinking.　　 As mentioned above, moving to the front line is one of the most effective ways for the apparel industry to face the impact of the epidemic. The online and offline integrated marketing model accelerates its penetration and gradually becomes normalized. Although the current pressure is huge, it is also a good time for apparel companies to truly develop an Internet sales system.　　Of course, the transformation of apparel companies is not just about transformation, e-commerce, and live broadcasting. How to better balance physical stores and online stores is also a major challenge for apparel manufacturers.　　 Offline stores are not going to eventually die out, but need to innovate themselves according to the needs of consumers. After the epidemic, consumers tend to pursue the ultimate cost-effective product without reducing their consumption level and quality of life with limited consumption funds. With the post-90s and 00s becoming the main force of consumption, and focusing on personalized consumption experience has become a feature of young people, changes in the clothing industry have come. Enterprises must first enhance their core competitiveness and constantly respond to changes in the market and consumers.　　The most urgent task for apparel companies in the current predicament is to do a good job of internal control, ensure cash flow, reduce inventory, and strive to survive before thinking about how to transform.......

Know the polypropylene spinning machine 2020/9/4

Generally, the spinning machine itself has 4 functional areas.① High polymer melting device: screw extruder.②Melt conveying, distribution, spinning and heat preservation device: elbow, spinning box (melt distribution pipe, metering pump, spinning head assembly).③Thread cooling device: spinning window and cooling sleeve.④Wire collection device: wet oiling mechanism, guide wire structure, winding machine or wire receiving device.Melting device(1) Function: The supply of solid materials, polymer melting, and quantitative melt extrusion.(2) Three screw sections: feeding section, compression section and metering section.(3) The working principle of the screw extruder is the division of the screw and the movement of the material in each area of the screw.① Feeding zone (curing zone) isometric screw.② In the first half (cooling zone), cooling water is passed through the jacketed coil or the inner core of the screw, <100℃ to prevent premature melting of the material and ring blockage to protect the screw drive mechanism from heat.③ The second half (preheating zone) prevents sudden temperature changes from the feed zone to the compression zone.④ Compression zone (melting zone) The gradual or abrupt screw melts the material (heating, shearing) and compressing (the volume of the screw groove becomes smaller); returning air or water vapor to the feeding zone.⑤ Shallow screw such as measuring area (homogenization area). Melt conveying, distribution, spinning and heat preservation device(1) The melt conveying pipeline from the elbow screw extruder to the spinning box (one end is connected to the screw outlet and the other end is connected to the melt distribution pipe of the spinning machine)-jacketed internal biphenyl-diphenyl ether mixture Heating (melt insulation).(2) Spinning box body, melt distribution pipe, ten biphenyl heating box, spinning pump and its transmission device, and spinning head assembly.① Principle of melt distribution pipe② Ensure that the melt reaches the same distance to each spinning position.

The return speed of textile foreign trade orders is expected to accelerate, and domestic demand is slowly starting! 2020/8/28

In the first seven months of this year, China's textile and apparel exports increased year-on-year. Nevertheless, industry insiders believe that in view of the continued growth of overseas epidemics, textile and apparel exports will still face greater pressure.　　Customs data shows that in July, China exported US$31.294 billion in textiles and apparel, a year-on-year increase of 16.1% and a month-on-month increase of 7.79%. In the first seven months, China's textile and apparel exports were US$156.482 billion, a year-on-year increase of 5.57%.　　Due to the impact of the epidemic, although China's textile exports fell sharply in the first quarter, since April, China's textile and apparel exports have begun to grow steadily. "The continued rebound in exports is mainly due to the fact that the company's early-stage orders have entered the peak of execution. At the same time, the surge in exports of epidemic prevention materials has also promoted exports to a certain extent." Zhang Jie said that from April to July, the export of textiles and clothing has been achieved for 4 consecutive months. increase. The export of textiles and clothing continues to be polarized. Driven by the substantial increase in the export of anti-epidemic materials, the export value of textiles has reached the highest level in the same period in history."Traditional clothing and clothing accessories exports are still in a declining channel year-on-year, mainly due to the slow return of foreign trade orders, the deepening of the domestic market in the off-season, the lack of transactions in the traditional clothing and clothing accessories market, and some companies continue to accelerate the transformation of medical textiles and other factors." Said Liu Jie, an analyst at Creative Information. It is understood that a large cotton spinning enterprise in Liaocheng, Shandong has launched a new non-woven project, and exports of textiles such as masks and protective clothing continue to increase in volume. However, due to the rapid expansion of production capacity, mask production has begun to lose money and some mask production equipment has stopped production.　　 Analysts believe that the epidemic has put the entire industrial chain of the textile and apparel industry in a cycle of severe weak demand and prominent overcapacity. The market wants to get better still depends on the demand for the apparel industry. “Domestic textile and apparel demand is relatively weak, and overseas demand is difficult to see a significant improvement. Recently, the overseas new crown epidemic continues to spread. Although some countries around the world have gradually liberalized after May, the economy has gradually recovered, but resumption of work does not mean resumption of production. , People's income is shrinking, and there is still a long time for consumption to get better." Zhang Jie said.At the same time, with the unblocking of European and North American societies and increasing activities, ports in these areas are facing more and more traffic congestion. If the congestion is not relieved, foreign trade exporters may have to pay extra for congestion in addition to freight. cost."Affected by global unilateral tradeism and industrial transfer, the share of China's textile and apparel products in the markets of major developed countries has continued to decline. In the past year, the proportion of the EU, the United States and Japan's imports of apparel from China has decreased by 1.15 and 1.46 respectively. At the same time, clothing imports from Vietnam and Bangladesh showed double-digit growth, and their market shares increased by 1.53, 1.41 and 1.63 percentage points, respectively." Zhang Jie said that Chinese textiles and clothing are traditionally used in Europe, the United States, and Japan. The export market share is being replaced by competitors such as ASEAN, India and Bangladesh.......
