Acrylic Synthetic fibers made from a polymer. First acrylic fibers were created in 1941 and trademarked under the name Orlon. Strong and warm, acrylic fiber is often used for sweaters and tracksuits and as linings for boots and gloves, as well as in furnishing fabrics and carpets. It is manufactured as a filament, then cut into short staple lengths similar to wool hairs, and spun into yarn. |
