Fubon dry goods conventional spinning process detailed, it is worth collecting! 2017/11/5

The term spinning is well known, How many people can understand the process, Xiao Bian today for everyone to introduce!Conventional spinning process is as follows: dry slice → melt extrusion → mixing → metering → filtration → spinning → cooling forming → oiled → winding → UDY cheese. Details see below:1, melt extrusionSlice relying on gravity from the feed into the screw extruder. Due to the rotation of the screw, the chip moves forward along the screw channel, and the heating element is installed on the outside of the screw rod sleeve to transfer the heat to the chip through the sleeve. At the same time, the friction between the chips in the screw extruder is squeezed The heat. The slices are heated and melted, and are compressed by the extruder to have a certain melt pressure.2, mixedThe static mixer is used to mix the melt at the outlet to enhance the uniformity of the melt and reduce the difference between the tube wall and tube center temperature and the residence time when the melt passes through the tube. If the melt is uniform, no static mixer can be used.3, measurementThe melt output from the screw extruder is measured by a metering pump assigned to each spinning station by a distribution pipe to ensure that the linear density of the yarn is uniform and the strips dry uniformly. At the same time, metering pumps can melt the melt pressure to meet the needs of high-pressure spinning.4, filterPre-spinning filter material such as sand filter out the melt impurities. Filter materials are emery, sea sand, ultra-fine glass beads, filters and so on. In high-pressure spinning, the filter layer will have a higher resistance, the melt friction heat, temperature, improve the rheological properties of the melt.5, spinningAfter filtration, the melt is dispensed to the various spinneret holes on the spinneret and discharged from the spinneret to form a melt stream.6, cooling formingThe melt stream is cooled down by the cooling medium, and the process of solidifying into filaments is called as cooling and forming. At the same time of cooling, due to the stretching effect of the spinneret, the melt stream is gradually refined before it is solidified. Cooling forming is completed in the spinning window, cooling air forced blowing out of the blowing window at the upper end of the spinning shaft can ensure uniform cooling conditions.7, oiledAs the nascent fiber is more dry, easy to produce static electricity, and the filament between the poor cohesion, loose filaments, the friction coefficient, can not be post-processing. Therefore, to spin yarn to oil. Although different oiling positions are different when spinning with different processes, the purpose of oiling the oil can play a role in favor of yarn bundling, reduction of static electricity and improvement of smoothness. Conventional spinning oil tanker are used to oil, the cooling of the forming of silk through the corridor to reach the winding machine, the contact with the tanker finish oiling.8, windingWinding by the upper and lower godets, horizontal guide wire and friction roller cooperate with each other to complete. After the oil on the yarn through the upper and lower guide wire to change the direction of tension after adjustment by the yarn guide wound on the bobbin. The tube and the winding roller head contact pressure at a certain pressure through the friction drive to maintain the same linear velocity, the speed is the spinning speed. Winding tension on the cheese forming and annealing have an impact on tension. Winding tension, overfeed rate and finish are the three important factors in winding forming.Fubon focus on research and development and production of chemical fiber equipmentTake you into the chemical fiber worldLearn more about spinning those things!Changzhou Fubon Chemical Fiber Machinery Factory mainly produces: polypropylene spinning machine, 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.......

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. PP plus EPR plus HDPE can maintain the rigidity, reduce the high EPR content caused by whitening phenomenon, improve the impact strength. In the case ofComposite materials (COMPOUNDING) mixed with different materials, such as the addition of glass fiber, all kinds of inorganic mineral powder, organic wood flour, paper scrap or grain micro-film, in the PP material to improve the various physical properties. Mineral powder also includes: talc, calcium carbonate, barium sulfate, mica, carbon black, carbon fiber and bromide. In the case of8. 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.......

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.......

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.......

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.......
