What is polyester fiber fabric? What are its characteristics?
Polyester Fiber fabric is a synthetic fiber obtained by spinning polyester, which is condensed from organic dicarboxylic acids and diols. The research report on polyester chain points out that the polyester fibers produced in large quantities by industrialization are made of polyethylene terephthalate, which is marketed as polyester in China. It is currently the largest variety of synthetic fibers.
The specific gravity of polyester is 1.38; Melting point of 255-260 ℃, bonding begins at 205 ℃, safe ironing temperature is 135 ℃; The humidity absorption is very low, only 0.4%; The breaking strength of long fibers is 4.5-5.5 grams per denier, while that of short fibers is 3.5-5.5 grams per denier; The elongation at break of long fibers is 15-25%, while that of short fibers is 25-40%; High strength fibers can have a strength of 7-8 grams per denier and an elongation of 7.5-12.5%. Polyester has excellent wrinkle resistance, elasticity, and dimensional stability, as well as good electrical insulation properties. It is resistant to sunlight, friction, mold and decay, and has good resistance to chemical reagents. It can also withstand weak acids and bases. At room temperature, it has a certain ability to resist dilute strong acids, but poor resistance to strong alkalis. Polyester has poor dyeing performance and generally needs to be dyed with dispersed dyes under high temperature or in the presence of a carrier.

Polyester fibershave high strength and elastic recovery ability, making them sturdy, durable, Wrinkle Resistant, and iron free. Its light resistance is good, except for being inferior to acrylic, its sun resistance is better than natural fiber fabrics, especially behind glass, its sun resistance is very good, almost comparable to acrylic. In addition, polyester fabric has good resistance to various chemicals, with little damage from acid and alkali, and is not afraid of mold or insect infestation.
However, polyester fiber has poor water absorption and is not breathable. When worn in summer, it feels stuffy and stuffy. This is mainly due to the low moisture content and poor breathability of polyester fibers compared to natural fibers. That's why wearing polyester fabric clothes in summer makes us feel uncomfortable when the clothes stick to our skin after sweating. Moreover, it is prone to absorbing dust and generating static electricity. In winter, the wind and sand are strong, and it can be imagined that wearing polyester fiber fabric clothes is easily contaminated with dust, which not only causes unsightly appearance, but also the most annoying thing is the static electricity generated. Not only does it feel stinging, but if it is pants, they will also stick tightly to the skin due to static electricity, completely losing the shape of the pants, which is very unsightly. It is easily exploited by unscrupulous merchants, producing high-quality fabrics. Polyester fibers are difficult to visually distinguish from real silk in terms of texture and appearance, and have been exploited by unscrupulous merchants to make better use of them. In addition, many consumers do not understand that polyester fiber is the scientific name of polyester, and are misled by the new name as a high-end fabric. Some even believe it is a derivative of real silk, making it difficult for consumers to define the concepts of real silk and polyester fiber.
