Problems solved by technology

[0002] Polyamide fiber, commonly known as nylon, or PA for short, is a thermoplastic resin containing repeated amide groups on the main molecular chain. Moreover, the process temperature range is very wide, and its impact resistance and solubility resistance are better than nylon 66 plastics. It is widely used in petrochemical, national defense, machinery and textile industries. It is an important engineering plastic, but due to the large water absorption of nylon , leading to a large decrease in material rigidity, defects in mechanical strength, and high moisture absorption rate, resulting in a large molding shrinkage rate and affecting the dimensional stability of the product. Some nylon products that are used in contact with water, such as bathroom interior parts and irrigation shells Products, after long-term contact with water, the rigidity of the water-absorbing material decreases and it is easy to break
