Development and development of multi-component new functional yarns for product development Luo Dongyi, Yang Enping, Huang Jianchun (Demian Group Hengfeng Textile Co., Ltd., Dezhou, Shandong 253002) The existing common yarns have more or less certain defects. For example, fabrics made of pure cotton yarns have poor wrinkle resistance and wool textiles have poor machine washability. However, some chemical fiber products also have the disadvantage of the static electricity from the ball, which cannot meet the needs of people wearing comfortable and other functions. Therefore, in order to meet the needs of the market, our company has developed a multi-component new functional yarn. This product can have anti-pilling, anti-static, anti-vine resistance, machine-washing and other functions according to the different combinations. We first collected information on various new types of raw materials that have been industrially produced on the current market, investigated the current situation and trends of market demand, and based on Based on its own work basis and company characteristics, it has formulated product development variety programs and implementation plans and measures to ensure the smooth development of the research work. 1 Multi-component New Functional Yarn Variety Scheme Considering the use of the final product when formulating a plan Taking the main product, mainly from the knitted underwear products, according to the mastered fiber varieties, the main body is positioned in the development of high-inductivity products, and at the same time will create conditions for the development of other functional yarns and the final product development. The formulated variety plan is as follows: The three components wool + soybean protein modified fiber two components as the fourth species, the main purpose is to grasp the spinnability of soybean protein fiber and the characteristics of its compatibility with wool ten characteristics of raw materials Cashmere fiber is light in texture, soft in hand, elastic, warmth-keeping, soft in gloss, and similar in fiber and wool But without the medullary layer, scales close to the hair shaft, with irregular curl, good fluffiness, elastic recovery ability, fast coloration and dyeing, high dyeing rate, bright color after dyeing, expensive, known as soft gold Said.
As a new type of plant protein modified fiber, soy protein modified fiber has unique properties, fine fiber fineness and silky luster, making the designed product rich in silk texture; fiber feel soft and smooth, with wool warm Sex, so that the fabric has a good take comfort, so the soybean protein modified fiber is known as "man-made cashmere." The fiber's excellent moisture absorption and moisture-conducting properties enable the fiber to manufacture various kinds of underwear. In the process of human body wear, the body's dry and comfortable tangle is a new type of environmentally-friendly cellulose fiber. The academic name of this fiber is Lyocell, and Tencel is The brand name of Lyocell fiber produced by Acordis. In 1998, A-cordis also introduced Tencel A100 non-fibrillated fiber. This fiber has all the characteristics of the standard Tencel fiber as well as no fibrillation, because it does not require special equipment for fibrillation. Tencel A100 is The application prospects in the textile field are very broad. Modal fiber is a kind of “green†fiber that meets the requirements of environmental protection. It has the characteristics of natural fiber, good moisture absorption and permeability, soft handfeel, fast water absorption, large water capacity, excellent contact with skin, and elasticity. Large, good wear resistance and bright color after dyeing, shiny.
Acrylic acrylic fibers compared with conventional acrylic fiber, in addition to the original characteristics of the original acrylic fiber, due to its low denier, so that it feels more soft textiles, delicate style of the cloth, repeated taking care of the resulting tampons Roller and Daofu snarl are all down-brewed micro/AU yarn u nylon fiber has high strength, good softness and abrasion resistance, high elongation, low elastic modulus and small volume. The main physical properties of the raw materials used are shown in Table 1 Table 1 Main physical properties of various raw materials Performance Soybean Cashmere Fine Extra Cotton Acrylic Fiber Nylon Length (mm) Dry Strength (cN Wet Strength (cN Dry Elongation (%) Wet Extension Long Rate (%) Dry Modulus (cN Moisture Regain (%) Due to differences in the fineness of the various fibers mentioned above, the elongation and moisture regain are not equal, and the degree of static electricity generated during the spinning process is different. The length of the cashmere fiber is not Neat, low strength, curled, spinning technology design and spinning process should take into account the characteristics of different fibers to meet the requirements of the yarn standard 3 spinning process 3.1 process flow (pre-parallel) winding 3.2 process configuration And the main process parameters 3.2.1 Flower cleaning process According to the requirement of Modal fiber and nylon fiber to open and clean cotton, the clear flower adopts more loose, multi-comb, low-fat, low-speed and anti-sticking technology.
In order to reduce the number of blows, only one A036C was used in the process, and both the beater speed and the roll roller speed were reduced; to prevent fiber entanglement, the height of the A092A blender box was 1/3, and the V-roller's upper mouth was appropriately enlarged. Quantitative 380g/m, lap fixed length: 36m, lap roller speed 10rpm 3.2.2 Carding process Because of the better elasticity of Modal fiber and nylon fiber, and the poor cohesion of the fiber, in order to ensure the quality of the cotton net, reduce the The fiber is low, the high-knife and small-angle process is adopted for the dust removal knife, the closed small leakage bottom is used, the speed ratio of the cylinder roller is large, the distance between the cylinder plate is properly increased, the pressure of the pressurizing machine is increased, and the tension of the sliver is properly drawn. Decrease.
The specific process parameters are: the speed of the licker-in roller is 800rpm, the distance between the cotton plate and the licker-in roller is 0.30mm, the gap between the lithe roller and the cylinder is Q15mm, the cylinder speed is 330rpm, the cover plate speed is 73mm/min, and the cylinder and the cover plate are 0.280 .250.23 degree 22rpm, sliver basis weight 18. Since Modal fiber and nylon fiber have characteristics of easy bulkiness and elastic resilience, in order to prevent fiber winding, a large gauge, slow speed, and small tension draft are used in the pre-spooling process. Craftsmanship. Combined 8 roots, draft 8.2 times, roller gauge 12mm<16mm, front roller speed 150m/min, sliver quantitative 18.1g/5m mixed three lanes, due to the addition of cashmere fibers, roller gap to 30mm, before Roller speed 3.2.4 roving process due to fluffy cashmere fragile, Modal fiber and nylon fiber resilience is better, the rear zone draft multiple and tension drafting is relatively small grasp, twist slightly larger front roller speed 190rpm, roller gap 24mnK29mm, led Stretch 7 times, rear zone 1.35 times draft, twist factor 85, axial winding density 3.542 turns/cm 3.2.5 Spinning process due to a large roving twist, for a smooth retreat, the rear zone is appropriately enlarged, the front roller The speed should be reduced. The front rubber roller adopts a soft elastic rubber roller. The steel wire ring is heavier than when spinning cotton to reduce the hair roller front roller speed 35mm. The rear zone draws more than 4 multi-component full-molded knitted underwear. 4.1 The process flow raw materials enter the factory Inspection + weaving? Semi-finished products inspection?

Left and right process points and precautions: Temperature should not be too high 5 Conclusion After nearly one year of hard work, we have successfully developed a multi-component yarn, at the same time have formed a mature production process, and small batch production. It laid the foundation for the smooth development of future technological development work.
A sports hat or outdoor hat originally designed for use in sports, it can be a type of baseball cap or sun visor, now commonly seen at beaches and sports events for those who want to shield their eyes and face from the sun. Whilst players want their eyes shaded from the sun, they don`t want their head to overheat and therefore most caps in sports are made from lightweight and comfortable material such as polyester, cotton and mesh. And many sports caps have no additional support behind those front panels, it is the same all the way around the cap crown. We call it unstructured hat.
