The abrasion resistance of polyamide fiber is the best among all textile fibers. Under the same conditions, its abrasion resistance is 10 times of cotton, 20 times of wool and 50 times of rayon. If 15% polyamide fiber is added to wool or cotton spinning, its abrasion resistance is 3 times higher than that of pure wool or cotton.

The scientific name of nylon fiber is polyamide fiber, which was originally the trade name of the polyhexamethylene adipate produced by DuPont, that is, nylon hexamethylene chloride. Polyamide fiber is the first commercial synthetic fiber product of synthetic polymer. It is the first page of synthetic fiber, which is still the representative of polyamide fiber, because it was researched and invented by Caarothers of DuPont in 1937.
