What is the soft cloth made of?

Soft fabric is a kind of high density nylon fabric material.

Polyamide fiber is commonly known as nylon and PA in English, and its density is 1. 15g/cm3. It is the general name of thermoplastic resins with repeated amide groups [NHCO] in the molecular skeleton, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application, and its name depends on the specific number of carbon atoms in the synthetic monomer. It was invented by the famous American chemist carothers and his research team.
