Commonly used nylon fibers can be divided into two categories.
A class of polydydramines, which are made up of diamine and diacid, has a chemical structure of long-chain molecules:
H-[HN(CH2)xNHCO(CH2)yCO]-OH
The relative molecular weight of these nylons is generally 17,000-23,000. Depending on the number of carbon atoms used for binary amines and binary acids, different nylon products can be obtained and can be distinguished by the number added to the nylon, wherein the previous number is the number of carbon atoms of binary amines and the latter number is the number of carbon atoms of binary acids. For example, nylon 66 indicates that it is made of hexaamine and hexachloric acid, and nylon 610 indicates that it is made of hexamine and hexadic acid.
The other is derived from the concentration or open-loop polymerization of endamide, and the chemical structure of its long-chain molecules is:
H-[NH(CH2)xCO]-OH
According to the number of carbon atoms contained in its cell structure, different varieties can be named. For example, nylon 6, which means that it is made up of hexylamide open-loop polymerization containing six carbon atoms.
