Through modification technology, some new properties can be given to traditional polyester (PET fiber) and new polyester (PBT, PTT, pen, PLA, LCP) fibers, so that they have more "professional" technical characteristics. Fiber modification is generally realized by copolymerization, blending, increasing molecular weight, fiber forming, surface modification and so on. Two component compound Low viscosity pet (0.48dl / g) is used as component A, which is compounded with component B PBT (1.2dl / g) or PTT (1.2dl / g) in the ratio of 50 ∶ 50 after leaving the surface of the spinning board, and then drawn and shaped. The fiber has "permanent" elasticity of three-dimensional crimping, good spinnability and easy weaving. Composite fibers with good crimp properties and tensile recovery elasticity can also be obtained by using two kinds of PET chips with viscosity difference not less than 0.45dl/g (such as 0.45dl/g and 0.90dl/g). Skin core composite The leather core composite short fiber that has been industrialized mainly adopts "boss slit" or "needle tube" two-component composite components, with low melting point polyethylene or low melting point PET as the cortex and pet as the core layer. According to the area ratio of 1:1 concentric circle or eccentric circle section, it can be used for hot-melt bonded non-wovens dominated by polyolefin fiber and PET fiber respectively, and can also be used for special short fiber sewing thread. Island and lobed composite The key of polyester island fiber spinning technology is the synthesis of water-soluble modified polyester with "sea" component and the improvement of spinning components to increase the number of single fiber "islands". After fiber opening, the size of "island" component fiber can reach nanometer level.

CEY (composite SSY elastin fiber raw materials--CEY 180D/60F)is a new type of elastic composite fiber compounded with ssy elastic fiber raw materials through special compounding process. It has the characteristics of ssy elastic fiber. In the use of fabrics, it can not only have the elasticity and characteristics of ssy elastic fiber, but also produce special fabric style characteristics. The fabrics are novel and high-grade. Excellent elasticity and elastic recovery, soft feel, anti dirt and fluffy, sun and chlorine resistance, good moisture absorption and quick drying. After being processed into fabric, the surface of the fabric is smooth, wrinkle resistant and iron free, with stable size, moisture absorption and quick drying, moderate elasticity and comfortable wearability. It is a new functional textile material. The product solves the weaknesses and shortcomings of the original spandex elastic fabric, such as fear of chlorine bleaching, poor setting, unstable elasticity, poor care, easy foaming, excess elasticity, stuffy wearing, etc

SPH fiber is a new type of elastic fiber in the market in recent years. It is made of polyester compounds with different thermodynamic properties, PTT and pet, through parallel composite spinning, and then processed by relaxation heat treatment to form a crimped fiber with three-dimensional structure similar to sheep capillary and dense. Its tensile resilience is close to that of spandex, and its elastic durability is better than that of spandex. SPH fabric also has the characteristics of easy curling and easy dyeing. SPH fiber can be used for shirts and skirts in summer, trousers and skirts in spring and autumn. Compared with ordinary polyester fabric, SPH fabric is soft, fluffy, elastic and easy to deform in tension. After tensile deformation, SPH fabric has good tensile recovery performance and is prone to shear deformation, but the shear recovery is almost the same as that of ordinary polyester fabric. The surface smoothness of SPH fabric is equivalent to that of ordinary polyester fabric.

Flame retardant polyester has excellent flame retardancy. When polyester meets fire, it only melts and does not burn. Although it is washed with water for 35 ~ 50 times, its flame retardancy remains unchanged. Flame retardant polyester, modified polyester fiber with LOI of 26 ~ 34. The physical and mechanical properties, appearance and post-processing properties of most flame retardant polyester (including filament and staple fiber) are similar to those of ordinary polyester. Only a few fibers (such as wistel FR) have slightly lower strength than ordinary polyester, but do not affect textile processing. Because the structure of flame retardant fiber is loose and dye molecules are easy to enter, the dyeing speed is faster than that of ordinary polyester, and it can be dyed with disperse dyes or cationic dyes. The manufacturing methods mainly include: (1) copolymerization flame retardant modification. For example, tetrabromobisphenol A hydroxyethyl ether or phosphorus containing compound is used as comonomer, which is prepared by transesterification and polycondensation with dimethyl terephthalate and ethylene glycol. It is prepared by melt spinning and drawing; (2) Blending flame retardant modification, adding phosphorus containing compound or halogen antimony composite flame retardant in the spinning melt, and then preparing it by melt spinning and drawing; Or use composite spinning components to add flame retardant in the core layer, and the skin layer is ordinary polyester. The fiber prepared by this method not only improves the flame retardant and flame retardant durability, but also reduces the impact on the fiber properties. Although the effect of flame retardant modification by blending is not as good as that of copolymerization, the process is simple; (3) Flame retardant finishing is prepared by surface polymerization or graft copolymerization on fibers or fabrics with alkene monomers containing phosphorus or halogen, or by trimeric nitrile ammonia treatment.

SD+CD is made of cationic dyeable polyester and common polyester by compounding and stretching. During the use of uneven air interaction to produce changes in the length of the pitch, and then after weaving in the fabric surface will produce two color change effect.

RPET fabric (Coke bottle environmental protection cloth) is a new type of green environmental protection recycled fabric, its source of low carbon, so that it creates a new concept in the field of regeneration, the current use of recycling "Coke bottle" recycled fiber made of textiles, the recycling material can be recycled into PET fiber, effectively reduce the waste. "Coke bottle" recycled filament can be used to make t-shirts, children's wear, men and women's casual wear, windbreaker, down (cold) clothing, work uniforms, gloves, scarves, towels, bath towels, pajamas, sportswear, jackets, handbags, blankets, hats, shoes, bags, umbrellas, curtains and so on. Coke bottle recycled staple fiber can be twisted into yarn and then woven into fabric to make a variety of other products. Recycle PET fabric makes use of recycled environmental protection fiber raw materials recovered from Coke bottles, which are rolled into fragments and processed by wire extraction.

Rpet fabric process: Bottle recycling → bottle slice quality inspection separation → Bottle slice → filament drawing and cooling collecting →Recycled PET yarn → woven surface At present, 80% of the global capacity of recycled polyester is in China. International brands use the sustainable development index for the evaluation of recycled polyester, and the sustainable development index of recycled polyester is even higher than organic cotton, hemp and other raw materials. Duan Furong, practitioner of international terminal brand industry, pointed out that all major terminal retail brands are actively embracing green and environmentally friendly materials, and have developed their own sustainable development strategies in materials. For example, Ikea, Nike and Decathlon all aim to use 100% recycled polyester in all their polyester products by 2025. International terminal brands have strict requirements on the core control points in the process of recycled polyester, such as polyester purity testing, separation of waste PET bottles, CLEANING of APEO, moisture content testing, heavy metal filtration, t...
