Nylon fibers are made from (or consist mainly of) nylon.
Nylon fibers are used in a number of textile applications, most often in (1) outerwear and protective fabrics, (2) carpets, (3) high strength textiles such as parachutes and tires, (4) industrial fabrics, and (5) other high-strength fabric applications.
Most commercially available nylon fibers are based upon N66, N6, or a copolymer based upon those two nylons.
