Melange yarn is one kind of color spinning. It is a yarn with unique color mixing effect, which is made of two or more different fibers after full mixing after reactive environmental protection dyeing. This kind of yarn has a natural and harmonious color and is not easy to fade. After the yarn is finished, it does not need printing and dyeing. It is directly knitted or woven, reducing the cost and environmental pollution. It is suitable for knitted sweaters, casual clothes, etc; The fibers of different colors adopt a variety of mixed spinning methods, showing natural and uniform colors, smooth and soft surfaces, and durable colors; The woven fabric has a hazy three-dimensional effect, which is both fashionable and elegant.

Differential fiber generally refers to the chemical fiber that is innovative to the conventional chemical fiber or has certain characteristics. Generally, through chemical modification or physical deformation, the morphological structure and physical and chemical properties of the fiber are different from those of conventional chemical fibers, so as to achieve bionic effect or improve the performance of chemical fibers. Generally, there are many differential fibers of polyester. Many differential fibers not only appear in a single form, but also are composite fibers to reflect the superimposed fiber style. For example, the composite of high shrinkage silk and ordinary shrinkage fine denier silk forms the characteristic of different shrinkage, which gives the fabric the style of peach skin velvet without sanding the surface, and then adds the characteristics of different size and different cross-section, which can make the fabric show elegant pearl luster. Differential fibers are mainly used in clothing and decorative fabrics.

Lyocell fiber, commonly known as "velvet", took natural plant fiber as raw material and came out in the mid-1990s. It is known as the most valuable product in the history of man-made fiber for nearly half a century. It has many excellent properties of natural fiber and synthetic fiber. Lyocell is a green fiber. Its raw material is inexhaustible cellulose in nature. There is no chemical reaction in the production process and the solvent used is non-toxic.

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.
