The polyester chain research report pointed out: the industrialized mass production of polyester fiber is made of polyethylene terephthalate, and the Chinese trade name is polyester. It is currently the largest variety of synthetic fibers. Let's take a look at what polyester fiber is. The specific gravity of polyester is 1.38; the melting point is 255~260℃, and it starts to bond at 205℃, and the safe ironing temperature is 135℃; the moisture absorption is very low, only 0.4%; the breaking strength of filament is 4.5~5.5 g/denier , Short fiber is 3.5~5.5g/denier; the elongation at break of filament is 15~25%, short fiber is 25~40%; the strength of high-strength fiber can reach 7~8g/den, and the elongation is 7.5~ 12.5%.
Polyester has excellent wrinkle resistance, elasticity and dimensional stability, good electrical insulation properties, resistance to sunlight, abrasion, mildew and moth, good resistance to chemical reagents, and resistance to weak acids and alkalis. At room temperature, it has a certain resistance to dilute and strong acids, but it has poor resistance to strong alkalis. The dyeing performance of polyester is poor, and it is generally required to be dyed with disperse dyes at high temperature or in the presence of a carrier.
Polyester has many excellent textile properties and wearability. It can be used in a wide range of applications. It can be purely woven or blended with natural fibers such as cotton, wool, silk, hemp and other chemical fibers. Wool-like, cotton-like, silk-like and linen-like fabrics with good washability, easy-to-dry, non-iron and washable and wearable properties. Polyester fabric is suitable for men's and women's shirts, outerwear, children's clothing, interior decoration fabrics and carpets. Because polyester has good elasticity and bulkiness, it can also be used as cotton wool. In industry, high-strength polyester can be used as tire cords, conveyor belts, fire hoses, cables, fishing nets, etc., as well as electrical insulation materials, acid-resistant filter cloths, and papermaking blankets. The non-woven fabric made of polyester can be used for interior decoration, carpet backing, medical industry cloth, fleece, lining, etc.
The characteristics of polyester fiber sun fabric
1. Shade, light and ventilate. It can not only eliminate up to 86% of solar radiation, but also keep the indoor air unobstructed, and the outdoor scenery can be clearly seen.
2. Insulation. Polyester fiber sunshine fabric has good heat insulation performance that other fabrics do not have, which greatly reduces the utilization rate of indoor air conditioning.
3. UV protection. The polyester sun fabric can withstand up to 95% of ultraviolet rays.
4. Fire prevention. Polyester sunshine fabric has flame retardant properties that other fabrics do not have. The real polyester fiber fabric will leave the internal skeleton glass fiber after burning, so it will not be deformed, while the ordinary fabric will have no residue after burning.
5. Moisture-proof. Bacteria cannot multiply, and the fabric will not be mildewed.
6. Antistatic. Does not absorb solid particles in the air and does not adhere to dust.
7. Constant size. The material of the fabric itself determines that it is not malleable, does not deform, and maintains its flatness for a long time.
8. Easy to clean. Can be placed in clean water for scrubbing.
9. Anti-tear. No need for reinforcement, natural tear resistance, significant wind resistance and withstand frequent use.
