Nylon is the United States outstanding scientist Carothers (Carothers) and his leadership of a research team developed, is the world's first synthetic fiber. The appearance of nylon makes textiles take on a new look. Its synthesis is a major breakthrough in synthetic fiber industry and an important milestone in polymer chemistry.

Nylon, English name polyamide (PA), is a general term for thermoplastic resin containing repeated amide gene -[NHCO]- on the molecular backbone. Including aliphatic PA, aliphatic aromatic PA good aromatic PA. Among them, aliphatic PA has many varieties, large yield, widely used, and its name is determined by the specific number of carbon atoms of the synthetic monomer.

Nylon has many characteristics, so it is widely used in automobile, electrical equipment, machinery, traffic equipment, textile, papermaking machinery and so on. With the MINIaturization of automobiles, the high performance of electronic and electrical equipment, and the acceleration of the process of lightweight mechanical equipment, the demand for nylon will be higher and greater. Especially nylon as a structural material, its strength, heat resistance, cold resistance and other aspects put forward high requirements.

The inherent shortcomings of nylon are also an important factor limiting its application, especially for PA6 and PA66, which have a strong price advantage compared with PA46 and PAl2, although some properties can not meet the requirements of the development of related industries. Therefore, it is necessary to expand its application field by modifying it and improving its performance. PA has strong hygroscopicity and poor dimensional stability due to its strong polarity, but it can be improved by modification.
