Where does acrylic fiber come from?

Acrylic fiber is a synthetic fiber made from a polymer called polyacrylonitrile, which is derived from petroleum-based products. The production process involves the polymerization of acrylonitrile, followed by spinning the resulting polymer into fibers. These fibers are then processed and finished to create various textiles used in clothing, upholstery, and other applications. Acrylic fibers are known for their softness, warmth, and resistance to moths and mildew.
