Polyester fiber has high strength, high modulus, and low water absorption, and it has a wide range of uses as civil fabrics and industrial fabrics. As a textile material, polyester staple fiber can be purely spun, and is also especially suitable for blending with other fibers; it can be blended with natural fibers such as cotton, linen, wool, and other chemical staple fibers such as viscose, acetate, polypropylene Blending of short fibers such as nitrile fibers. Cotton-like, wool-like and linen-like fabrics made of pure spinning or blending generally have the original excellent properties of polyester fibers, such as fabric wrinkle resistance and pleat retention, dimensional stability, wear resistance, washable and wearable. However, some of the original shortcomings of polyester fibers, such as static electricity and dyeing difficulties in textile processing, poor sweat absorption and air permeability, and easy to melt into cavities in case of sparks, etc., can be mixed to a certain extent with the addition of hydrophilic fibers. alleviated and improved. Polyester twisted filament (DT) is mainly used to weave various silk-like fabrics, and can also be interwoven with natural fiber or chemical staple fiber yarn, and can also be interwoven with silk or other chemical fiber filaments. Series advantages.
Polyester textured yarn (mainly low elastic yarn DTY) is the main variety developed in my country in recent years. It is different from ordinary filaments in that it has high bulkiness, large curl, strong wool feeling, softness, and high elastic elongation (up to 400%). The fabric woven with it has the characteristics of good warmth retention, excellent covering and drapability, and soft luster. It is especially suitable for weaving suit fabrics such as woolen and serge, outerwear, coats and various decorative fabrics such as curtains, tablecloths, Sofa fabric etc. Polyester air textured yarn ATY has good cohesion and smoothness with network yarn, and can be directly used in water-jet loom in the form of bobbin yarn. It is suitable for weaving imitation silk and thin fabrics, and can also weave medium-thick fabrics. The application of polyester fiber in industry, agriculture and new technology fields is also becoming more and more extensive, such as cords, conveyor belts, ropes, electrical insulation materials, etc. Polyester strong yarn has high strength and initial modulus, good heat resistance, fatigue resistance and shape stability, and is especially suitable for spinning tire cords. Using polyester cord to manufacture tires can reduce their flat spots.
