Polyester fiber fabric is a synthetic fiber spun from polyester condensed by organic diacid and diol. The research report of polyester chain points out that the polyester fiber produced in large quantities in industry is made of polyethylene terephthalate, and the trade name in China is polyester. It is the largest variety of synthetic fibers at present. Polyester specific gravity 1.38, melting point 255 ~ 260℃, and bonding began at 205℃.

Polyester has excellent wrinkle resistance, elasticity and dimensional stability, good electrical insulation, sunlight resistance, friction resistance, mildew resistance and moth resistance, good chemical resistance, weak acid and alkali resistance. At room temperature, it has a certain ability to resist dilute acid and strong alkali. The dyeing performance of polyester is poor, so it must be dyed with disperse dyes at high temperature or in the presence of carriers.

Application scope of polyester fiber

Polyester has many excellent textile properties and wearability and is widely used. It can be woven pure, or blended with natural fibers such as cotton, wool, silk and hemp and other chemical fibers to make wool-like, cotton-like, silk-like and hemp-like fabrics with various colors, fastness, scratch resistance, easy washing, easy drying, no ironing, good washing and wear resistance. Polyester fabric is suitable for men's and women's shirts, coats, children's wear, interior decoration fabrics, etc.

Because polyester has good elasticity and bulkiness, it can also be used as wadding cotton. In industry, high-strength polyester can be used as tire cord, conveyor belt, fire hose, cable, fishing net and so on. It can also be used as electrical insulation material, acid-resistant filter cloth and papermaking blanket. Polyester nonwoven fabric can be used for interior decoration, carpet backing, cloth for pharmaceutical industry, flocking, lining and so on.
