1, general sportswear fabrics are: gold velvet, mercerized velvet, polyester cotton; At present, the high-tech fibers used are: nylon-nylon fabric, functional fiber, PTFE waterproof and temperature-permeable laminated fabric, Coolmax fiber, silicone resin and lycra;

2. The shortcomings of early sportswear were made of cloth, cotton and hemp. Heavy weight, great friction with the body and insufficient flexibility often inhibit athletes from creating good results in sports. At this time, people began to explore new materials, eager to find lighter, tougher, more flexible and other materials with better performance to make sportswear, so that athletes can achieve better sports results. The continuous expansion and enterprising, the appearance of high molecular polymers such as nylon fiber and artificial polyester, blew the horn of the change of clothing fabric form. Compared with tradition, nylon clothing has great advantages in weight loss, while the jacket made of nylon fiber and the lining of artificial polyester velvet have better warmth retention effect. So sportswear began to use these chemical fibers instead of natural fibers and gradually became the mainstream. Early nylon clothing still has some defects, such as poor air permeability, wear resistance, easy cracking and deformation. While improving nylon, researchers developed materials with better performance. So far, countless synthetic products have been born.

Second,

1, a training coat, also known as a coat, is the outermost garment. Coats are generally large in size and have long sleeves, which can cover other clothes on the upper body when worn. The front end of the coat has buttons or zippers for wearing. A coat is usually used to keep warm or keep out the rain. You can run.

2. Wearing fitness training clothes during exercise can protect our bodies and make the training reach a better state. I often wear adidas Training's new fitness training clothes in autumn. You can feel that the package is very good when you wear it. It is said that the high-elastic fabric can make the muscles of the back, shoulders, abdomen and other main parts of the body evenly distributed to prevent muscle tremor, affect the training effect and even cause soft tissue injury.
