Polyester fiber is a synthetic fiber obtained by spinning polyester that is polycondensed with organic dibasic acid and glycol. It is a type of synthetic fiber made from polyester as raw material by melt spinning. The main variety is polyethylene terephthalate fiber, usually polyester fiber refers to this fiber, and China calls it polyester. It is currently the largest variety of synthetic fibers.
Polyester fabric is an ideal textile material. Its resilience (ie, elasticity) to deformations such as elongation, compression, and bending is close to that of wool. Because of the greater rigidity of the fiber macromolecular chain, the elastic modulus is high. The fiber is not easy to deform, and the processed fabric will not wrinkle after washing, and it can be ironed. It has strong drug resistance and is not prone to mildew and insect damage, so it is relatively simple to keep. The folds shaped by thermoplastic have high strength and good durability. The strength of polyester fiber is generally 44~71cN/dtex, which is 1 time higher than cotton and 3 times higher than wool. It also has good heat resistance, light resistance and abrasion resistance, and can be used within -70~170℃.
Advantages and disadvantages of polyester fiber
Polyester fiber is a synthetic fiber obtained by spinning polyester formed by polycondensation of organic dibasic acid and glycol. It is commonly known as polyester, which is widely used in apparel fabrics. Polyester has excellent wrinkle resistance, elasticity and dimensional stability, good insulation performance, and a wide range of uses. It is suitable for clothing of men, women and children. What kind of fabric is polyester fiber? Polyester fiber has high strength and elastic recovery ability, so it is durable, wrinkle-resistant and non-iron. Its light fastness is better, except that it is worse than acrylic fiber, its light fastness is better than natural fiber fabric, especially the light fastness behind the glass is very good, almost equal to acrylic fiber. In addition, the polyester fabric has good resistance to various chemicals, and the degree of damage to it by acid and alkali is not large. At the same time, it is not afraid of mold or insects. What kind of fabric is polyester fiber? The editor above lists a series of advantages of polyester fiber. Everyone knows that everything has its two sides. There are advantages and disadvantages. So what are the disadvantages of polyester fiber? The poor hygroscopicity of ester fiber is due to its texture; then it has poor air permeability; finally its dyeing performance is poor, and it needs to be dyed with disperse dyes at high temperatures.
