Poliéster e poli fiado são fibras sintéticas comumente usadas na indústria têxtil. Embora compartilhem semelhanças, existem algumas diferenças importantes entre eles.   O poliéster é uma fibra sintética feita de um polímero chamado tereftalato de polietileno (PET). É produzido através de um processo denominado polimerização, onde o PET é derretido e extrusado em filamentos finos. Esses filamentos são então combinados para criar uma fibra forte e versátil. O poliéster pode ser processado posteriormente para criar diferentes tipos de têxteis, incluindo fios.   O poli fiado, por outro lado, refere-se a fibras de poliéster que foram transformadas em fios. O processo de fiação envolve torcer ou girar as fibras de poliéster juntas para formar um fio contínuo, que é então enrolado em um carretel ou cone. Isso resulta em um fio com aparência macia e texturizada. O poliéster fiado tem um toque mais natural e semelhante ao algodão em comparação com os fios de poliéster tradicionais. Diferenças: Processo de manufatura: O poliéster é produzido por meio de polimerização, enquanto o poliéster fiado é criado por meio da fiação de fibras de poliéster em fios. Textura e aparência: Os fios de poliéster têm uma aparência suave e elegante, enquanto os fios de poliéster fiados têm uma aparência mais texturizada e natural. Sinta e armar: Os fios de poliéster fiados têm um toque mais macio e flexível em comparação com os fios de poliéster normais, que podem parecer mais rígidos. Resistência e durabilidade: Como as fibras de poliéster são frequentemente usadas por sua resistência e durabilidade, os fios fiados de poliéster podem herdar essas qualidades, tornando-os adequados para diferentes aplicações. Formulários: Os fios de poliéster têm uma ampla gama de aplicações, incluindo vestuário, têxteis-lar, tecidos industriais e muito mais. Os fios fiados de poliéster, com sua textura mais macia, são frequentemente usados em roupas, estofados e outros produtos têxteis onde é desejada uma sensação mais suave ao toque.   Em poucas palavras. poliéster é uma fibra sintética enquanto poli fiado refere-se a fibras de poliéster que foram fiadas em fios.

1.Ring spinning   Ring spinning refers to the process of drawing a fiber strip from a sliver or roving through a ring wire ring. The winding speed of the bobbin is faster than that of the wire ring, and the cotton yarn is twisted into fine yarn. For example, in carded, combed and blended spinning, the wire ring is driven by the bobbin through the yarn strip to rotate around the steel collar for twisting. At the same time, the friction of the steel collar makes its speed slightly lower than that of the bobbin and is wound. Ring spinning is the most widely used and most common spinning method on the market.   2. Open-End spinning: Open-end spinning does not use spindles, but mainly relies on multiple components such as combing rollers, spinning cups, and false twist devices. The combing roller is used to grab and comb the fed cotton sliver fibers. The centrifugal force generated by its high-speed rotation can throw out the grabbed fibers. The rotation speed of the spinning cup (a small metal cup) is more than 10 times higher than that of the combing roller. The resulting centrifugal effect discharges the air in the cup outward; according to the principle of fluid pressure, the cotton fibers enter the airflow cup and form a fiber flow, which moves continuously along the inner wall of the cup. At this time, there is a yarn head outside the cup, which leads the fibers on the inner wall of the cup out and connects them. In addition, the drilling effect generated by the high-speed rotation of the cup with the yarn tail is like "feeding" cotton fibers while adding yarn rubbing to connect the yarn with the fibers on the inner wall of the cup. It is stretched under the winding tension of the yarn tube, and the yarn is continuously output to complete the process of open-end spinning.   Characteristics of open-end spinning Air-jet spinning has the advantages of high speed, large yarn roll, wide adaptability, simple structure and no need for spindles, steel collars or wire rings, which can double the output of fine yarn.   3.Vortex spinning Vortex spinning is a new spinning method that uses a fixed vortex spinning tube to replace the high-speed rotating spinning cup for spinning. In a sense, vortex spinning is the real air-jet spinning. The fiber strips are fed by the cotton feeding roller, opened into single fibers by the licker-in roller, and fed into the vortex tube at high speed from the cotton conveying pipeline by the action of the air flow. The vortex tube consists of a core tube and an outer tube. There are three tangential air inlets on the outer tube, and the lower end is connected to the blower. The blower continuously extracts air from the tube, and the outside air enters the vortex tube along the air inlet, generating a vortex-shaped airflow. When the rotating upward airflow reaches the core tube, it merges with the fibers entering the cotton conveying pipeline, forming a condensed fiber ring along the inner wall of the vortex tube, stably around the axis of the vortex tube, rotating at high speed, and twisting the fibers into yarn. The yarn is continuously drawn out from the yarn guide hole by the lead-out roller and wound into a bobbin.   Advantages of vortex spinning: fast speed and high output   The spinning speed of vortex spinning machine is 100~200m/min, and the practical speed is generally 100~160m/min. Domestically, vortex spinning machine is used to spin 6~12 British yarn, the spinning speed is 100~140m/min, and the single yield is 600~800 (kg/thousand spindles·h), which is equivalent to 4~5 times that of ring yarn; such as spinning 40 public acrylic yarn, using 10 sets (192 heads/set) PF-1 vortex spinning machines, the output reaches 400kg/h. It is equivalent to the output of 20 sets (4000 heads) BD-200 air-spinning machines, and the output of 40 ring spinning machines with 16320 spindles. The output of one vortex spinning head is equivalent to the output of 2.08 air-spinning heads or 8.5 ring spindles. Since vortex spinning relies on vortex twisting, if research and improvement continue, the spinning speed can continue to increase.   Short process flow and high yield   Vortex spinning is to spin fiber strips directly into cone yarn, so like other new spinning methods, it can save the two processes of roving and winding. Since the breakage rate of vortex spinning is very low, the return loss is small, and the yield is as high as more than 99%.   Strong spinning adaptability and suitable for making fleece products   Vortex spinning can spin fibers with a length of 38~60mm, and is suitable for pure and blended yarns of cotton and chemical fibers. The yarn structure is relatively bulky, so its dyeability, slurry absorption and air permeability are relatively good, and the yarn's anti-pilling and wear resistance are also relatively good. The yarn count range is limited to medium and low count yarns, which are suitable for making fleece products. For example, 38mm long chemical fibers (acrylic, chloroprene, viscose, etc.) are spun into 6~12 count yarns, which are woven into fleece clothes, fleece pants, scarves, cushions, sofa fabrics, furniture fabrics and small tablecloths and other knitted fleece products.   Simple operation and convenient jointing   Vortex spinning uses vortex tubes to form yarn. Since the vortex tube is stationary and has no high-speed rotating parts, the joint is very convenient and simple. There is no need to clean after the end is broken, which improves the working environment. There are no special requirements for the pre-spinning equipment and temperature and humidity. Since vortex spinning has no high-speed rotating parts, there is no problem of high-speed bearing lubrication, less wear and tear, low noise, and easy maintenance.   Production practice shows that there are also some limiting factors in the development of vortex spinning.   a. The range of raw materials suitable for vortex spinning is limited to short chemical fibers and medium and long fibers. Due to the quality of the yarn, its competitiveness in the field of fine yarn is not strong.   b. The yarn structure of vortex spinning is relatively loose, and the long segment has good uniformity, but the strength is low and unstable, which limits its development into the field of fine yarn.   c. Although vortex spinning uses air vortex to replace the rotor of air spinning, it overcomes the wear problem and excessive bearing load caused by the high-speed rotation of the rotor of air spinning, but it still cannot solve the problem of yarn arms formed by the free-end yarn tail when it rotates at high speed in the vortex tube, which leads to greater centrifugal force and tension. Therefore, its spinning speed cannot make a breakthrough.   d. Due to the poor fiber straightness and the short coagulation process, the yarn structure of vortex spinning is loose and the yarn strength is low. Therefore, its products are also limited. It is only suitable for chemical fiber raw materials and spinning of coarse knitting yarn or thick pile yarn, which do not require high strength, or spinning core-spun yarn with filament as the yarn core. Despite this, vortex spinning, which also feeds cotton strips to directly form yarn, has the conditions and possibility to realize the production of fully automated continuous production lines. Since the roving frame, spinning frame and automatic winding machine are eliminated, the floor space, labor and investment are reduced, so it has its unique advantages and will further replace ring yarn and air-spun yarn in the field of knitting yarn. Therefore, it is necessary to continue research and improvement to overcome its disadvantages and limitations and make it a new type of spinning method with unique characteristics.     3.Air-jet spinning Air-jet spinning is a new spinning method that uses high-speed rotating airflow to twist the yarn into yarn. Air-jet spinning uses cotton sliver feeding, four-roller double short rubber ring super-large drafting, and twisting into yarn through a fixed nozzle. After the yarn is drawn out, it is wound onto the yarn tube through a yarn clearer and directly wound into a package yarn. Due to the special spinning mechanism of air-jet spinning, the structure and performance of air-jet yarn are significantly different from those of ring yarn, and its products have a unique style.   Characteristics of air-jet spinning and its products:   a. High spinning speed. Air-jet spinning uses air twisting and no high-speed rotating parts (such as steel wire rings in ring spinning), which realizes high-speed spinning. The spinning speed can reach 120-300 meters/minute, and the output per head is equivalent to 10-15 times that of ring spinning per spindle.   b. Short process flow. Air-jet spinning has two fewer processes, roving and package, than ring spinning, saving about 30% of plant area. Compared with ring spinning, 90 workers are needed for 10,000 spindles, which is about 60% less. The machine material consumption is about 30% lower than that of ring spinning, and the maintenance cost and maintenance workload are also reduced.   c. Good product quality and unique. The comprehensive evaluation of the quality of air-jet yarn is good. Except that the yarn strength is 5-20% lower than that of ring spinning, other quality indicators are better than those of ring spinning. The physical properties of air-jet yarn, such as CV value of yarn evenness, coarse and fine details and yarn defects, are better than those of ring yarn. The hairiness above 3mm is less than that of ring yarn. Although the yarn strength is lower, the strength unevenness is lower than that of ring yarn. It is suitable for weaving of new looms such as rapier looms and air-jet looms, and can increase the production efficiency of looms by more than 2%.   In addition to being similar to ring yarn, the quality of air-jet spinning is also unique. The friction coefficient of air-jet yarn is large, the yarn is directional, and its friction performance is also directional. The wear resistance is better than that of ring yarn, but the hand feel is harder.   By adding some devices to jet spinning, some special yarns can be developed, such as fancy yarn, core-spun yarn, mixed yarn, etc.   d. Wide variety of applications. Jet yarn can be used to make both knitted products and woven products, and has a wide variety of applications. The more common applications include: knitted T-shirt products, with a smooth and plump surface, no skew, few stripes, few stripe defects, anti-pilling, cool and breathable, and a strong three-dimensional sense; bedding, using the characteristics of good and stiff stripes of jet yarn, can obtain a smooth surface, thick feel, crisp and good breathability; leisure products, such as: double-sided leisure wear, sportswear, etc.     Based on the characteristics of jet yarn, unique style products can also be developed. For example, by using the stiffness and roughness of jet fabrics, they can be processed into imitation linen fabrics, crepe fabrics, imitation wool products, etc.

Compact Spinning: Compact spinning is a new spinning technology that is carried out on an improved new ring spinning frame. Its spinning mechanism is mainly: a fiber cohesion zone is added in front of the traction device of the ring spinning frame, which basically eliminates the spinning twisting triangle between the front roller and the twisting point. After the fiber whiskers are output from the front mouth of the front roller, they first pass through the mesh leather ring on the outer jacket of the special-shaped suction tube. The whiskers move on the mesh leather ring. Due to the contraction and polymerization of the airflow, the whiskers are gathered and rotated through the suction groove of the special-shaped tube, gradually turning from a flat belt to a cylinder. The ends of the fibers are twisted into the yarn, so the yarn is very compact, the yarn appearance is smooth, and the hairiness is less. Compact spinning yarn has higher strength and less hairiness. It is least likely to produce abrasion during the weaving process. Advantages of compact spinning: the yarn has very little hairiness, especially hairiness above 3mm, which also improves the efficiency of the subsequent loom and the smoothness of the fabric; the yarns have strong cohesion and high strength; the yarns are uneven, and the coarseness and fineness indicators are better than traditional yarns. However, the cost of compact spinning equipment is high, which increases the equipment investment of the spinning mill, and except for the great improvement in the hairiness index, the improvement of other yarn indicators such as yarn, coarseness, and fineness is not large.   Siro Spinning: Siro spinning is to use double roving feeding on the spinning frame, and two roving strands parallel to each other and maintained at a certain distance are stretched by rollers in the spinning drafting area, and two small triangles are formed at the front roller jaws, and then they are gathered together and twisted into a yarn strip. Due to the transmission effect of twist, a small amount of twist is added to the single strand before the two strands are twisted together, so the twisted yarn has a different style from the general single yarn. Advantages of siro spinning: The fibers on the surface of siro spinning are neatly arranged, the yarn structure is compact, the hairiness is less, and the pilling resistance is good. Compared with ply yarn fabrics, siro-woven fabrics feel softer and smoother. Siro spinning can be used for woven fabrics and knitted fabrics, and can also replace ply yarn for high-count and high-density fabrics.   Siro Compact Spinning: Two rovings are fed into the same drafting mechanism of the ring spinning machine through the double bell mouth at a certain interval, and are drafted at the same time in a parallel state. After coming out of the clamping point of the front roller, they enter the pneumatic gathering area. The surface of the special-shaped tube with double grooves and negative pressure inside each spinning part is covered with a mesh ring, which is driven by the friction of the output roller. The two strands of fiber outputted by the front roller are adsorbed on the position corresponding to the double grooves on the surface of the mesh ring by negative pressure. The strands of fiber move forward with the mesh ring while being controlled by the gathering and output by the output jaws. The two bundles of fiber after gathering have a relatively compact structure. After slight initial twisting, they are combined at the combination point, and then twisted again and curled onto the yarn tube to become a compact twine yarn with a similar structure to a strand. Advantages of compact siro spinning:Compact siro spinning is a combined spinning method that combines compact spinning and siro spinning. The yarn spun by this technology combines the excellent characteristics and quality of the two spinning methods. Compared with traditional ring spinning single yarn and siro yarn, compact siro yarn has less hairiness, higher strength, and more siro spinning plying effect. The hairiness is greatly reduced during compact siro spinning, especially the hairiness above three millimeters, which is reduced by 70%. It is an ideal raw material for spinning high-end fabrics and has good development prospects.
