Polyester is an important variety in synthetic fiber and is the trade name of polyester fiber in China. It is a fiber-forming polymer prepared by esterification or transesterification and polycondensation of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG). - Polyethylene terephthalate (PET), fibers made by spinning and post-treatment.
English: Terylene polyester is widely used in the manufacture of clothing fabrics and industrial products. Polyester has excellent shape properties. The flattened, fluffy form or pleats produced by the polyester yarn or fabric after being shaped, can be used for a long time after repeated washing in use.
Performance 1, high intensity. The short fiber strength is 2.6 to 5.7 cN/dtex, and the high strength fiber is 5.6 to 8.0 cN/dtex. Due to its low hygroscopicity, its wet strength is essentially the same as the dry strength. The impact strength is 4 times higher than that of nylon and 20 times higher than viscose. 2, good flexibility. The elasticity is close to that of wool, and when it is stretched by 5% to 6%, it can be almost completely recovered. The wrinkle resistance is superior to other fibers, that is, the fabric is not wrinkled, and the dimensional stability is good. The modulus of elasticity is 22 to 141 cN/dtex, which is 2 to 3 times higher than that of nylon. 3. Heat resistance and thermal stability are the best in synthetic fiber fabrics. 4. The surface of the polyester is smooth and the internal molecules are closely arranged. 5, good wear resistance. Wear resistance is second only to nylon with the best abrasion resistance, better than other natural and synthetic fibers. 6, good light resistance. Lightfastness is second only to acrylic. 7, corrosion resistance. It is resistant to bleaches, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. Resistant to dilute alkali, not afraid of mildew, but hot alkali can decompose it. 8. Dyeing is poor, but the color fastness is good and it is not easy to fade.
The broad varieties of polyesters include short fibers, drawn yarns, textured yarns, decorative filaments, industrial filaments, and various differential fibers. Polyester staple fiber 1. According to physical properties: high strength and low elongation type, medium strength medium extension type, low strength medium extension type, high modulus type, high strength and high modulus type 2. According to post processing requirements: cotton type, hair type , hemp type, silk type 3. According to the use of distinction: clothing, cotton, decorative, industrial 4. Distinguish according to function: cationic dyeable, moisture absorption, flame retardant, colored, anti-pilling, antistatic 5. According to fiber Section distinction: Shaped wire, hollow wire. Polyester filament 1. Primary silk: undrawn yarn (conventional spinning) (UDY), semi-pre-oriented yarn (medium speed spinning) (MOY), pre-oriented yarn (high speed spinning) (POY), high orientation yarn (Ultra High Speed ​​Spinning) (HOY) 2. Stretched wire: drawn wire (low speed drawing wire) (DY), full drawing wire (spinning drawing one step method) (FDY), full wire drawing (spinning) One-step method) (FOY) 3. Deformed yarn: conventional textured yarn (DY), tensile textured yarn (DTY), air textured yarn (ATY).
Improvement of polyester
There are many types of polyester fiber fabrics. In addition to woven pure polyester fabrics, there are many products blended or interwoven with various textile fibers to make up for the lack of pure polyester fabrics and to exert better performance. At present, polyester fabrics are developing in the direction of naturalization of synthetic fibers such as wool, imitation silk, imitation linen and suede. 1. Polyester artificial silk fabric The polyester fabric with silk appearance style woven from round or special-shaped polyester filament or staple fiber yarn has the advantages of low price, anti-wrinkle and non-ironing, and is popular among consumers. Common varieties are: polyester silk, polyester silk, polyester satin, polyester georgette, polyester interwoven silk and so on. These varieties have the silky drape, smooth, soft and pleasing to the eye. At the same time, they are also made of polyester fabric, which are crisp, wear-resistant, easy to wash and non-iron. The fly in the ointment is that these fabrics have poor moisture permeability and are not very cool. In order to overcome this shortcoming, more new polyester fabrics have emerged, such as high moisture absorbing polyester fabric. 2. Polyester wool fabric is made of polyester filament yarn such as polyester elastic yarn, polyester mesh yarn or various special-shaped polyester yarn, or medium-long polyester staple fiber blended with medium-long viscose or medium-length acrylic fiber. The woolen-woven fabrics, which are woven from the yarns, are called worsted wool fabrics and medium-length wool fabrics, and their prices are lower than those of similar wool fabrics. It has the characteristics of full fluffy and elastic and good elasticity, and has the characteristics of strong and durable polyester, easy to wash and dry, flat and crisp, not easy to deform, not easy to fluff and pilling. Common varieties are: polyester impeller, polyester bomb Huada, polyester elastic tweed, polyester network silk wool fabric, polyester sticky long tweed, polyester nitrile hidden strip and so on. 3. Polyester imitation hemp fabric is one of the most popular fabrics in the international apparel market. It is made of polyester or polyester/viscose crepe woven into plain or ribbed fabric, which has the dry feel and appearance of hemp fabric. Such as the thin imitation Ma Molik, not only the appearance is rough, feels dry, and comfortable and cool, therefore, it is very suitable for the production of summer Shirts and skirts. 4. Polyester suede fabric is one of the new polyester fabrics. It is made of fine denier or superfine denier polyester fiber. It is specially processed to form fine short-wool polyester suede fabric on fabric base fabric. The fabric is generally made of a nonwoven fabric, a woven fabric, and a knitted fabric. It has the characteristics of soft texture, fine and full fluff, rich hand feeling and strong and durable style. Commonly used are artificial high-grade deer skin, artificial high-quality deer skin and artificial ordinary deer skin. Suitable for women's clothing, high-end dresses, Jackets, suits and so on.
China's polyester industry development
Polyester is the world's largest and most widely used synthetic fiber variety. At present, polyester accounts for more than 60% of the world's synthetic fiber production. It is widely used in textiles such as clothing, bedding, various decorative fabrics, special fabrics for national defense and other industrial textiles, such as filter materials, insulating materials, tire cords, conveyor belts, etc. In recent years, with the continuous rapid growth of the domestic economy and the continuous improvement of the consumption power of domestic residents, the demand for polyester staple fiber in the domestic region has also increased. The production capacity of China's polyester series products is growing at an alarming rate. The rapid growth of polyester fiber production capacity has made China gradually become an important processing base for the world's polyester products. From January to November 2007, China's polyester fiber manufacturing industry realized a total industrial output value of 242,668,877,000 yuan, an increase of 22.56% over the same period of the previous year; realized cumulative product sales income of 236,413,801 thousand yuan, an increase of 21.65% over the same period of the previous year; The total profit was 4,987,999 thousand yuan, an increase of 61.15% over the same period of the previous year. From January to May 2008, China's polyester fiber manufacturing industry realized a total industrial output value of 104,924,069 thousand yuan, an increase of 8.72% over the same period of the previous year; realized cumulative product sales income of 101,674,711,000 yuan, an increase of 10.82% over the same period of the previous year; The total profit was 1,495,129 thousand yuan, a decrease of 19.96% over the same period of the previous year. Polyester fiber is the most processed chemical fiber variety among all textile fibers. Developing differentiated varieties, increasing the added value of products, and improving the economic benefits of enterprises are of vital importance to the entire chemical fiber industry. Product differentiation is the development direction of polyester. China's polyester fiber producers are also developing in this direction. Therefore, the polyester industry still has great development potential.
