Polyester POY spinning machine process development process 2017/9/28

Polyester POY wire production process With the mechanical manufacturing technology and chemical processing technology progress, the development of fast, many types. According to the spinning speed can be divided into conventional spinning process, medium-speed spinning process and high-speed spinning process. According to the polyester raw materials can be divided into melt direct spinning and slice spinning. The direct spinning method is to feed the melt in the polymerization reactor directly to the spinning machine for spinning. The slice spinning method is a method in which the polyester melt obtained by the polycondensation process is dried, The screw extruder melts the chips into a melt and then spun. According to the process of three-step, two-step and one-step method.First, polyester POY spinning machine conventional spinning process    Conventional spinning, also known as low-speed spinning, is the first industrial production of a process line. A three-step process route using a spinning twist-twisting a false twist deformation (UDY-DY-TY). Spinning speed of 100O ~ 1500m / min, tensile twisting speed of 600 ~ 1100m / min. False twist deformation speed of 120 ~ 160m / min, post-processing draw ratio of 3.5 to 4.2 times (false twist deformation before processing). Spinning 33 to 167 dtex filaments.Conventional spinning can produce stretch yarn, but also the production of deformation of silk, which is characterized by mature technology, equipment, stable operation, easy to grasp the technology, product quality is better, good dyeing uniformity. Deformed yarn M (M wire for the measured deformation of the wire and the standard deformation of the color difference between the half-level within the normal dyeing silk) up to 96%. But the process is long, low production efficiency.Second, the speed spinning process    Medium speed spinning is a two step process. Spinning speed of 1800 ~ 2500m / min, made semi-pre-oriented wire (MOY). There are two process routes for medium speed spinning.    1.MOY-DY process    This process uses medium-speed spinning, low-speed drawing. A spinning speed of 1800 to 2500 m / min, a stretching and twisting speed of 800 to 1200 m / min, and a spun yarn of 33 to 167 dtex, typically 75 dtex and 50 dtex. Its production efficiency is lower than that of high speed spinning, and the product quality is worse than conventional spinning.    2.MOY-DTY processThis process uses medium-speed spinning, high-speed tensile deformation. MOY residual stretching ratio of 2.1 to 2.4 times the tensile deformation speed of 400 ~ 500m / min, can be spinning 55 ~ 88dtex deformation of the wire, more than 110dtex need to be two yarns together into a cheese. The production efficiency and product quality of this process is less than POY-DTY process.Third, high-speed spinning process    The spinning speed of high-speed spinning is 3000 to 3600 m / min, and pre-oriented yarn (POY) can be obtained. High-speed spinning has three process routes.    l.POY-DTY process    This process uses high-speed spinning, high-speed tensile deformation, is a typical two-step process line, is the production of the largest silk wire route.    POY processing speed is usually 400 ~ 800m / min, can be spinning 50 ~ 167dtex deformation wire (DTY). Its characteristics for the short process, high production efficiency, infrastructure investment province. POY can be long-term storage, long-distance transport; DTY quality.    2. POY-TY process    This T-art using high-speed spinning, low-voltage false twist deformation (rotor false twist method), can be spinning 111 ~ 167dtex deformation of the wire. This process is technically unreasonable.    3.POY-DY processThis process uses high-speed spinning, low-speed drawing twist, can be spinning 55 ~ 110dtex drawing wire. Stretching ratio of 1.3 to 1.7 times, using the general stretch twisting machine. This process is not as good as UDY.Fourth, spinning stretch one step process    This process using spinning, stretching two processes in a spinning stretch joint machine to complete, is a one-step process line. There are two kinds of production process, one is the spinning speed of 900 ~ 1500m / min, the tensile speed of 3200 ~ 4000m / min, the draw ratio of 3.5 times, can be spinning 55 ~ 165dtex stretch yarn; another The spinning speed is 2600 to 3500 m / min and the stretching speed is 5100 to 5500 m / min. This process produces filaments called FDY.Fifth, other spinning process    Polyester filament production process in addition to the above several, there are high orientation wire (HOY) production process and high crystalline wire (HCY) production process.    Highly oriented wire (HOY) also known as fully oriented wire. This process uses one-step ultra-high-speed spinning, spinning winding speed of 5500 ~ 6000m / min. Due to the large increase in the nozzle stretching, the degree of fiber orientation is greatly improved, but the crystal grain is large, the amorphous area is low, the dyeing performance of the fiber is better, but the elongation is too large (about 40%), Around the speed increased to 7000 ~ 8000m / min, elongation still can not meet the general requirements, is still in the experimental production stage.    High-crystalline wire (HCY) is made by one-step drawing using high-speed spinning heat pipe. In the ordinary high-speed spinning process, before the fiber coagulation in the oil, add a section of heat pipe, the hot air will be heated to the glass above the glass transition temperature (softening point below), so that after the coagulation of the wire in the winding traction Under the effect of further stretching.......

The way to improve the spinning speed of polyester POY 2017/9/28

1. Chemical modification of polyester POY spinning. The so-called chemical modification technology refers to the use of meta-acid in the polymerization process or the addition of the third component, polymerization to obtain low crystallization rate of chemical modified polyester, high-speed spinning line fiber orientation and crystallization development is reduced. The purpose of chemical modification is to reduce the molecular weight of molecules and molecules between the molecular chain, so the need for greater stress to get the same degree of crystallinity, which is the first attempt to high-speed spinning POY silk used in a method.2. Physical modification of polyester POY spinning. The so-called physical modification technology refers to the use of conventional polyester raw materials, through the process of improvement and mixing additives and other methods to achieve the purpose of improving the speed of polyester POY spinning, in which the role of additives and additives and polyester blends with the dispersion close relationship. An additive is added to the melt spinning to add the additive to the polymer melt.3. Polyester POY spinning changes the melt spinning process. The method is based on the fact that 70% of the spinning stress in the high speed spun process comes from the air resistance and significantly reduces the air between the filament and the side blowing (quench air) by accelerating the side blowing to parallel with the spinning tow friction. Compared with the current side of the blowing process (side of the hair gently around the new filament) compared to the new process using the quenching gas along the axis of the beam blowing, and ultimately speed up the tow in the direction of the spinning speed.Fubon Machinery Polyester POY spinning machine uses the most advanced technology, can maximize the spinning speed.......

Polypropylene spinning machine manufacturers to share: the development of electrostatic spinning technology 2017/9/28

Polypropylene spinning machine is a kind of machine used for the production of silk fiber, and an electrostatic spinning machine is now very popular and efficient and high quality of a spinning machine, its electrospinning technology to spinning Silk industry efficiency has been greatly improved.Electrostatic spinning is a special fiber manufacturing process in which a polymer solution or melt is sprayed in a strong electric field. Under the action of the electric field, the droplets at the needle will be spherical into a conical shape (ie, "Taylor cone"), and from the tapered tip extension of fiber filaments. This way can produce nanoscale diameter polymer filaments.The word electrospinning was derived from electrospinning. In 1934, Formalas invented an experimental device for the preparation of polymer fibers with electrostatic force and applied for a patent, announcing the principle of electrospinning, which is considered to be the beginning of electrospinning fibers.At the beginning, the rapid development of electrospinning, with the development of nano-technology, electrostatic spinning technology has also been rapid development, the world has shown great interest in this technology.However, how to prepare high-performance multi-functional composite nanofibers is the key, so the study of electrospinning non-polar nanofibers has just begun. Promise nanofibers have potential applications in many fields.With the development of nanotechnology, electrospinning as a simple and effective production of nanofibers can be a new processing technology, biomedical materials, filtration and protection, catalysis, energy, optoelectronics, food engineering, cosmetics and other fields play a huge role TheIn the field of biomedicine, the diameter of nanofibers is smaller than that of cells, which can simulate the structure and biological function of natural extracellular matrix. Most tissues and organs are similar in form and structure to nanofibers, which are used for tissue And the repair of organs to provide a possibility; some electrospinning materials have good biocompatibility and biodegradability, can be used as a carrier into the human body, and easy to be absorbed; combined with electrospinning nano-fiber also has a large surface area, porosity And so on. Therefore, it has attracted the attention of researchers in the field of biomedicine, and has been well applied in drug controlled release, wound repair, biological tissue engineering and so on.(2) The filtration efficiency of the fiber filter material increases with the decrease of the fiber diameter. Therefore, reducing the fiber diameter becomes an effective method to improve the filter performance of the fiber filter material. In addition to the small diameter, the electrospinning fiber has the advantages of small aperture, high porosity and good fiber homogeneity, which has great potential in gas filtration, liquid filtration and individual protection.③ electrospinning fiber can effectively control the fine structure of the fiber, combined with low surface energy of the material, can be obtained with super-hydrophobic properties of the material, and is expected to be used in the ship's shell, oil pipeline wall, high-grade glass, automotive glass. However, if the electrospinning fiber material is to be used in the above-mentioned self-cleaning field, it is necessary to improve its strength, abrasion resistance and the fastness of binding of the fibrous membrane material to the base material.(4) The catalyst particles with nanostructure are easy to agglomerate, thus affecting their dispersibility and utilization. Therefore, the electrospinning fiber material can play a uniform dispersion effect as a template, and also can play the flexibility and easy operation of the polymer carrier. Can use the catalytic material and polymer micro-nano-size surface composite to produce a strong synergistic effect, improve the catalytic performance.⑤ electrospinning nanofibers have a high specific surface area and porosity, can increase the sensing material and the role of the detection area, is expected to greatly improve the sensor performance. In addition, electrospinning nanofibers can also be used in energy, optoelectronics, food engineering and other fields.Electrospinning technology has played a very important role in the construction of one-dimensional nanomaterials, but some preparation methods still need to be studied, for example, nozzle structure, in addition, to improve the application of electrospun fiber membrane in ultrafine filtration applications, Fiber diameter, this area still need further study.......

Analysis on the Development of Spinning Machine 2017/9/28

A machine (spinning machine of chemical fiber) is a machine for forming a fibrous polymer solution or melt into a filament. According to the different fiber spinning methods, spinning machine is divided into wet spinning machine, melt spinning machine, dry spinning machine three types.Wet spinning machine for viscose fiber, acrylic, vinylon and other spinning. The main feature is the polymer solution from the spinneret hole in the coagulation tank solidification into raw fiber, spinning speed is low, often 100 meters / min below the high-speed spinning speed of up to 200 m / min or so. Wet spinning machine is divided into two kinds of short fiber and long fiber.① short fiber spinning machine: the spinning liquid from the infusion tube into the metering pump accurately metering through the filter into the spinneret, from the nozzle hole into the solidification bath into the solidification bath, solidified after the primary fiber through the guide wire collection And then washed or stretched. Staple fiber spinning machine is characterized by a large number of spinnerets (plates) in the spinneret, usually 3000 to tens of thousands of holes.② filament spinning machine: and short fiber spinning machine is different from the coagulation of the wire after the winding mechanism. From the coagulation bath out of the wire after washing through the guide wire, through the reciprocating movement of the wire funnel into the high-speed rotation of the centrifugal tank. Such a spinning machine is called a centrifugal tank spinning machine; if the filament is wound around a bobbin through a guide wire, it is called a bobbin spinning machine; if a part of the post- Called semi-continuous spinning machine; if the spinning and post-processing all the processes are continuous in the spinning machine to complete, is called continuous spinning machine. Viscose cord production line using continuous spinning machine. Spinning filament spinneret generally in the 150 hole below the spinning cord fiber holes to the number of holes up to 3000 holes.Melt spinning machine for spinning equipment such as polyester, nylon and polypropylene. The characteristic is that the melt finishes the cold wind solidifies the fiber, the cold wind is the high efficiency filter, the regulating valve, the deflector evenly blows to the fine flow. Spinning speed is high, generally 600 ~ 1500 m / min. There are two kinds of melt spinning machine.① filament spinning machine: polymer chips from the hopper into the screw extruder after being melted and pushed by the screw into the spinning box through the catheter. Melt in the box by the spinning pump metering sent to the spinneret (plate), by the spinneret hole melt flow in the spinning window encountered cold air cooling and curing into fiber, oil by the volume The winding mechanism is wound on the bobbin. The number of filaments of filament spinnerets is generally several to several holes. Spinning curtain line up to about 200 holes, spinning brown wire when only one hole, this time the melt stream with water bath cooling solidification into silk. Melt spinning filament spinning machine in the 1970s the trend is: long spinning, that is, each spinning site with 2,3,4,6 or even more spinneret to improve the machine production; high-speed spinning Silk, spinning speed of 3500 to 4000 m / min, or even up to 5000 m / min or more; large package, each cheese package volume is generally up to 10 kg to dozens of kilograms; continuous, spinning and stretching A spinning machine at the same time to complete, but also to the spinning, stretching, deformation processes are completed in a spinning machine (referred to as BCF production), in the production of polypropylene and nylon has been applied. This machine is compact, small footprint, high production efficiency. In addition, the degree of automation of the spinning machine is also increasing.② short fiber spinning machine: Compared with the filament spinning machine, it is characterized by the use of porous number of large spinneret, the general number of holes for the 400 ~ 1100, has been developed into porous spinning, the number of holes up to 4000; In the spinning corridor in the use of circular hair blowing or blowing side of the blowing side of the cooling system, the spinning part of the winding mechanism is not a separate part of the wire through the guide wire or small rotor, the tractor will tow Lead the wire to the wire, and then lay the tow in the barrel.

What is the standard for the selection of masterbatch? 2017/9/28

Masterbatch is a plastic, fiber coloring new products, in the production of masterbatch when the masterbatch has a certain requirement.The masterbatch used in the production of masterbatch, require color masterbatch and plastic raw materials and additives between the mixing ratio should be appropriate, otherwise the production of masterbatch may not meet the requirements.(1) masterbatch and resin and additives in the mixed use can not have a chemical reaction, this procurement in the choice of masterbatch varieties to cause enough attention. Masterbatch need to solvent resistance, color masterbatch but also a small migration. This will produce the masterbatch and plastic raw materials will not send chemical reactions.(2) the purchase of masterbatch to use the dispersion and color strength are very good masterbatch. In general, the smaller the masterbatch particles, the better the dispersibility of the masterbatch, the color strength is also strong. The production of masterbatch dispersed to do.(3) we use the masterbatch, we must also consider what is used to produce plastic products, such as the production of children's toys are required color masterbatch should be non-toxic; if the production of outdoor plastic products, we choose weather resistance and resistance Aging are good masterbatch.......

Classification of Polypropylene Plastics 2017/9/28

Polypropylene is the largest individual in all plastic ranges, and is the most widely used category. It can be sorted by different substrates. It can still be different in the classification of the melt flow rate, or even according to individual needs Add additional additives and then identify the use of norms, such as: single polymer, MFR: 12 or so can be used for general injection of finished products, but also the production of multifilament fiber, but also specifically to create a broad molecular weight distribution to improve the fiber weaving after processing Sex; also can add lubricant and anti-adhesion agent to increase the opening to facilitate the finished product requirements of plastic bags. So it extends a lot of specifications, but the general physical properties of almost, in the non-special use of the other is a substitute for each other. Try to use the different materials for classification for reference, and one by one explanation.1. General level (HOMOPOLYMER) single polymer, the mainland known as homopolymer, the Department of pure propylene polymerization of raw materials.2. IMPACT COPOLYMER is a single polymer to add ethylene propylene rubber, the impact of high and low mainly depends on the level of rubber content, good or bad degree of cold mainly depends on the level of ethylene content. The raw material manufacturers process different, the highest ethylene content is also different.3. Transparent grade (RANDOM COPOLYMER) random copolymer, the addition of ethylene ethylene copolymerization, ethylene irregularly dispersed in the polymer, mainly to reduce the crystallinity of the polymer and thus improve the transparency. In the case of4. High-level (HIGH ISOTACTICITY or HIGH CRYSTALLINITY) to reduce the PP polymer dislocation structure of the content, the relative increase in regular structure content, also improve the crystallinity. Mainly to improve the rigidity of raw materials, thermal denaturation temperature, surface hardness, scratch resistance and gloss. Of course, the addition of nucleating agents will also contribute to the improvement of the above properties5. Heat sealing (TERPOLYMER) is a random copolymer extension, generally propylene containing ethylene (non-EPR) content of up to 3.5%, but there are processes can be added to 5%, the higher the ethylene content of the product the more soft, , The softening point, the lower the heat sealing temperature, and sometimes in order to increase the ethylene content with butadiene or other third component to become a tri-co-polymer to achieve the above physical properties. In the case of6. Alloy grade (ALLOY) different high proportion of plastic raw materials can be described as alloy grade, such as PP to add LDPE can improve the softness and impact strength, in the processing can also reduce the necking and increase the smoothness of the molding can also be reduced Falling phenomenon.

Rubber (RUBBER) rubber, TPR (thermoplastic rubber) and TPE (thermoplastic elastomer), sometimes difficult to break, and a variety of definitions have, most of the rubber can be mixed with PP, with the exception of EPR series, it is also difficult to define the mixing is located in the alloy or composite materials. Often often mixed with PP rubber EPR and EPDM, suitable for direct mixing with the production of PP CATALLOY, PLASTOMER, ENGAGE, TAFMER, KRATON and SANTOPLENE and so on. In the case of9. Special specifications (SPECIALS) not covered in the previous category can be classified into this category, for example: high melt strength raw materials (HMS, High Melt Strength) can be used in the foam to improve the surface air tightness to improve the foaming effect , But also can reduce the phenomenon of sheet metal forming material.......

Development and Application of Seaweed Fiber 2017/9/28

Seaweed fiber as a new type of biodegradable regenerated fiber, is seaweed plants (such as seaweed, seaweed) isolated alginic acid as raw material of fiber, its products have good biocompatibility, biodegradability and so on Special features, and rich in resources, it is estimated that the world's oceans have more than 25,000 kinds of seaweed [1], algae fiber excellent performance in the textile field and medical field has been widespread concern.1 development of seaweed fiber1.1 Development of foreign seaweed fiberBritish chemist ECC Stanford [2-3] As early as January 12, 1881 published in a British patent, first introduced from the brown algae phytoplankton (LaminariaStenophylla) extracted from a gel-like material , He put the material extracted with dilute alkali solution named Algin, acid added after the gel is Alginic acid, that is, alginic acid.In 1944, the British Speakman and Chamberlain published their research on alginate fiber [4-6]. Speakman and Chamberlain studied the properties of fibers processed from six groups of alginic acids with different molecular weights. The results show that the relative molecular mass of alginic acid has a certain effect on the strength of fiber, but its degree of influence is not great.During the period from 1912 to 1940, some German, Japanese and British patents published reports of alginate salts that were available for soluble seaweed. It has been reported in 1947 that seaweed fiber with calcium alginate and sodium alginate as raw materials can be made into wool textiles, surgical gauze and wound covering materials. British studies in the 1960s and 1970s show that Steror's SORBSON is a well-preserved, well-worn wounded material that can be used to treat severe infections with seaweed fiber. The seaweed fiber and wound Exudate contact, the formation of hygroscopic gel, the wound can be kept moist, to promote rapid wound healing.According to the literature, Japan's Acordis specialty fiber company is the world's first to achieve high-volume production of seaweed fiber manufacturers, the process is a leading position. Japan's Forest Company has developed a seaweed fiber [8], which is mainly extracted from seaweed algae powder, which consists of sodium alginate aqueous solution with CaCl2 as a coagulation bath, wetted and replaced with methanol (L.97g), the strength of 1.7cN / dtex (l.92g / d), the company since 1993 in the country sales of seaweed fiber towels, since 2000 in South Korea Sales seaweed fiber underwear, has been extended to Europe and Southeast Asia and other countries. Seaweed fiber can reflect far infrared rays, resulting in negative ion warming and health effects, in addition to clothing can also be used for food industry or pharmaceutical industry to do jelly or thickener, new use can do wound bandage or band-aid.1.2 Development of domestic seaweed fiberGan Jinghao et al [9] reported the first study of alginate fiber in China. The research group as early as 1981, combined with foreign research on alginate fiber, with 5% sodium alginate spinning solution, by wet spinning preparation of calcium alginate fiber. It has been found that the concentration of calcium ions in the coagulation solution is diluted as a result of constant consumption, and it is most suitable to use a saturated aqueous solution of calcium chloride as a coagulating liquid for ease of control. The strength of the fibers after drying at 60 ° C under a pressure of 2000 Pa was 0.44 cN / dtex to 1.76 cN / dtex. Sun Yushan [10] in 1990 in detail the production process of alginate fiber. The fiber group obtained by wet spinning and stretched in a gaseous medium was 2.67 cN / dtex. In order to improve the chemical stability of calcium alginate fiber, the research group using cellulose acetate, polyvinyl alcohol, chitin and other fiber coating treatment, the fiber has a certain chemical stability, can be maintained in saline for two weeks Keep insoluble. After treatment of calcium alginate fibers with metal ions such as zinc, aluminum, iron, chromium and the like, the fibers can be insoluble after two months of immersion in physiological saline.In 2004, Professor Xia Yanzhi of Qingdao University was appointed chief scientist of Qingdao seaweed fiber project. The application of seaweed fiber in the new technology and seaweed fiber in the functional textiles, essential flame retardant materials and other aspects of the application of innovation and development, opened up a new field of marine biological resources applications. Its main project 863 plan "seaweed resources from the processing of fiber and deep processing of key technology development" to carry out the industrial production of seaweed fiber.In 2007, Qingdao University disclosed a patent for chitosan grafted seaweed fiber and its preparation and use [11]. This fiber has good hygroscopicity and antibacterial properties due to the surface coating of chitosan , And non-toxic, harmless, high safety and biodegradability, in medicine, environmental protection and other fields have a good application prospects, as a hemostatic treatment of new materials, especially for the manufacture of gauze wound dressings. Fiber strength: 1.5d ~ 2.5d. Elongation at break: 4% to 10%. Breaking strength: 1.8g / d ~ 3.1g / d.2 seaweed fiber preparation2.1 Preparation of raw materialsAt present, in the preparation of seaweed fiber can be used as raw materials, the most commonly used is soluble sodium salt powder, that is, sodium alginate. The production process: first with dilute acid treatment of seaweed insoluble alginate into alginic acid, and then alkali heating extraction, the formation of soluble sodium salt dissolved, filtered, add calcium salt calcium alginate precipitation, the precipitation of acid Liquid treatment into insoluble alginic acid, dehydration after alkali conversion into sodium salt, after drying is sodium alginate.2.2 Preparation of seaweed fiberSeaweed fiber is usually prepared by wet spinning, that is, soluble alginate (usually sodium alginate) dissolved in water to form a viscous solution, and then through the spinneret hole to the divalent metal cation (Mg2 + excluded) in the coagulation bath , Forming a solid insoluble alginate filament filament.3 characteristics of seaweed fiber3.1 High hygroscopicityCan absorb a lot of wound exudate, extend the time to replace the bandage, reduce the number of replacement and care time, reduce nursing costs.3.2 easy to removeThe alginate fibers are contacted with the exudate to form a soft gel. High-M alginate fiber can be used to remove the warm saline solution to remove; high G alginate bandage puffs can be removed to remove the whole, the wound tissue of the new wound has a protective effect to prevent the removal of gauze when the wound caused by secondary trauma The3.3 High oxygen permeabilityAfter the moisture absorption to form a hydrophilic gel, combined with the hydrophilic group of "free water" to become oxygen transmission channel, oxygen adsorption - diffusion - desorption process, from the external environment into the wound tissue; and fiber high G The macromolecular skeletal junction of the fiber, the hard part of the hydrogel (oxygen through the pores) to avoid the wound hypoxia, promote wound healing. Changzhou Fubon Chemical Fiber Machinery Factory mainly produces: polypropylene FDY spinning machine, polypropylene FDY production line, polypropylene FDY equipment, polypropylene FDY machinery, polyester POY spinning machine, polyester POY production line, polyester POY equipment, polyester POY machinery, FDY spinning machine, polyester FDY machine, polyester FDY equipment, polyester FDY production line, polyester FDY machine, nylon FDY spinning machine, nylon FDY production line, nylon FDY machinery, nylon FDY equipment, spandex spinning machine, spandex production line, spandex Equipment, spandex machinery, spinning special parts, polyester small experimental machine, polypropylene small experimental machine, nylon small experimental machine.......
