Sportswear is generally made of polyester.
Blended with cotton using movement is one of the most common polyester suit fabrics, polyester fiber has many excellent textile performance and the performance, with natural fibers such as cotton, wool, silk, linen and other chemical fiber blended interwoven, design and color is various, fast crisp, easy to wash easy to dry, wash and wear and wash and wear performance good wool-like, imitation cotton, imitation silk, imitation linen fabric.
Because you need to sweat a lot during exercise, wearing pure cotton clothes is indeed very sweat absorption, but the sweat is absorbed on the clothes, the clothes become wet, it is difficult to evaporate out.Some sports fabrics, such as Climafit by ADIDAS and Drifit by Nike, are 100% polyester, which allows you to quickly evaporate your sweat so you don't feel any weight or stick to your body.
Advantages of polyester
1.High strength.The strength of short fiber is 2.6 ~ 5.7cN/dtex, and that of high strength fiber is 5.6 ~ 8.0cN/dtex.Because of its low hygroscopicity, its wet state strength and dry state strength are basically the same.Impact strength is 4 times higher than nylon, 20 times higher than viscose fiber.
2.Good elasticity.The elasticity is close to wool and can be almost completely restored when elongated by 5% ~ 6%.The crease resistance is better than other fibers, that is, the fabric does not crease and has good dimensional stability.The elastic modulus is 22 ~ 141CN /dtex, 2 ~ 3 times higher than nylon.Polyester fabric has high strength and elastic resilience, therefore, it is strong, durable, wrinkle-resistant and ironing free.
3.The heat-resistant polyester is made by melt spinning, and the formed fiber can be melted by heating again. It belongs to thermoplastic fiber.The melting point of polyester is relatively high, and the specific heat capacity and thermal conductivity are small, so the heat resistance and thermal insulation of polyester fiber is higher.It's the best synthetic fiber.
4.Good thermoplasticity, poor fusion resistance.Because of its smooth surface and close arrangement of internal molecules, polyester is the best heat-resistant fabric among synthetic fabrics. It has thermoplasticity and can be used to make pleated skirts with long-lasting pleats.At the same time, the polyester fabric has poor melting resistance, and it is easy to form holes when it meets soot and sparks.Accordingly, when wearing, should avoid to wait for contact with cigarette butts, spark as far as possible.
5.Good wear resistance.Wear resistance is second only to the best wear resistance of nylon, than other natural fibers and synthetic fibers are better.
