First, polyester fabrics have high strength. The strength of short fiber is 2.6-5.7cN/dtex, and the strength of high-strength fiber is 5.6-8.0cN/dtex. Due to its low hygroscopicity, its wet strength is basically the same as its dry strength, and its impact resistance is 4 times higher than that of nylon. Viscose is 20 times taller.
Second, the elasticity of polyester fabrics is super strong. The elasticity is close to wool. When the elongation is 5% to 6%, it can be almost completely recovered. The polyester fabric can be quickly restored to its original shape by repeatedly rubbing it without leaving wrinkles. The elastic modulus is 22-141cN/dtex, which is more Nylon is 2 to 3 times higher, which is unmatched by other fabrics.
Third, polyester fabrics have good heat resistance. It can be said that polyester has the best heat resistance and strong plasticity among chemical fiber fabrics. If it is made into a pleated skirt, it can keep the pleats well without excessive ironing.
Fourth, polyester fabrics have better light resistance. Items made of polyester fabrics are usually more light-resistant than natural fiber fabrics. It is basically no problem to expose polyester fabric items to the sun, and there is no need to worry about any side effects. This feature makes polyester fabrics almost as lightfast as acrylic fabrics.
Fifth, polyester fabrics have good abrasion resistance. The abrasion resistance is second only to the nylon with the best abrasion resistance, and it is better than other natural fibers and synthetic fibers.
Sixth, the chemical resistance of polyester fabrics is good. Textiles made of polyester fabrics are not damaged by acid and alkali, so some bleaching agents and oxidizing agents do not work at all, and polyester textiles are not afraid of mildew and insects.
