synthetic textile fibers
synthetic textile fibers have revolutionized the textile industry. Such artificial fibers are usually long-chain polymers, produced industrially by the condensation of many small units. Orlon is the trade name for a polyacrylonitrile fiber made from natural gas, oxygen, and nitrogen. It combines bulk with light weight and is resistant to acids and sun damage. It is used for sweaters and other clothing. Dacron is the trade name for a polyester fiber of great strength and wrinkle resistance. It is often blended with other fabrics. Vinyl fibers, such as Saran, are used for screening and heavy-duty upholstery. See also fiberglass; nylon; rayon.
