Polyamide (PA, commonly known as nylon) was the first resin developed for use in fibers by the DuPont company in the United States, which was industrialized in 1939. In the 1950s, we began to develop and produce injection products to replace metals to meet the requirements of lightweight and cost reduction of downstream industrial products. The main chain of polyamides contains a number of repeating amide groups, which are used as plastics, called nylon, and when used as synthetic fibers, we call polyamide. Polyamides are made from diamine and dibasic acids, and can also be made from omega-3 amino acids or cyclolactams. A variety of polyamides can be prepared according to the number of carbon atoms contained in diamine and diacid or amino acid. There are dozens of polyamides, among which polyami-6, polyami-66 and polyami-610 are the most widely used.
