Cotton fabric Cotton is the most common fabric in the textile field. Of course, there are many kinds of cotton. Cotton treated by different processes also has different characteristics, such as combed cotton, washed cotton, etc. but cotton has good moisture absorption and permeability, soft touch and excellent warmth keeping effect, making the fabric more comfortable after wearing. Silk fabrics Silk fabrics are also common. Silk woven with silk as raw material is also called real silk. Of course, some of them are imitation silk made of chemical fiber. Similarly, there are many varieties. The clothing that can be made is mainly women's clothing. The overall characteristics are light, soft and breathable. Mulberry silk is a relatively precious material. Therefore, this kind of silk is generally only used for the production of high-end clothing, such as evening dress. Woolen fabric As for the types of common textile fabrics, wool is also a common one. The main raw materials are actually made of all kinds of wool, which can be used to make clothes such as suits, coats and coats. The overall feature is good warmth retention. Hemp fabric Fabrics made from hemp fiber are called hemp fabrics. Flax, ramie and ramie are common. The main characteristics of hemp fiber are moisture absorption, air permeability and wear resistance, and its corrosion resistance is also very excellent. At the same time, hemp fabrics can absorb harmful substances in the air and volatilize them. The defect is that they have a rough hand feel, and the overall wearing experience is not as good as cotton fabrics. Chemical fiber fabric Chemical fiber fabrics have good wear resistance, and can be mass produced because of low cost. Common chemical fiber fabrics include polyester, nylon, etc. they occupy a large share in the market by virtue of price advantage and practicality. Chemical fiber is commonly used to produce short sleeves, trousers and other fabrics.

1. to make the pigment have better dispersibility in the product, the pigment must be refined during the production of masterbatch to improve the dispersibility and coloring power of the pigment. The carrier of the special color masterbatch is the same as the plastic of the product, which has good matching. After heating and melting, the pigment particles can be well dispersed in the plastic of the product. 2. it is conducive to maintaining the chemical stability of the pigment. If the pigment is used directly, the pigment will absorb water and oxidize due to its direct contact with the air during storage and use. After the color masterbatch is made, the quality of the pigment can remain unchanged for a long time because the resin carrier separates the pigment from the air and moisture. 3. ensure the stability of the product color. The masterbatch particles are similar to the resin particles, which is more convenient and accurate in measurement. They will not adhere to the container during mixing, and they are evenly mixed with the resin. Therefore, the stability of the addition amount can be guaranteed, so as to ensure the stability of the product color. 4. the health pigments used to protect the operators are generally powdery, which are easy to fly when added and mixed, and will affect the health of the operators after being inhaled by the human body. 5. keep the environment clean. 6. easy to use

Cationic yarn belongs to modified polyester, chemical name: polybutylene terephthalate (elastic polyester), abbreviation: PBT, which is also represented by Cd in the factory. Because ordinary polyester (polyethylene terephthalate) has the disadvantages of low moisture absorption, poor dyeing performance, easy accumulation of static electricity, easy fuzzing, etc., it is usually modified with sulfonate as modifier into modified polyester that can be dyed with cationic dyes, or cationic activator is added before spinning or during spinning to prepare modified polyester. Such yarn is called cationic yarn, which does not need to be dyed at high temperature like ordinary polyester, It can be dyed at room temperature.

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
