Acrylic fibers

Acrylic fibers are synthetic fibers made from a poly acrylonitrile. To be called acrylic the polymer must contain at least 85% acrylonitrile monomer. Typical co monomers are vinyl acetate or methyl acrylate. DuPont created the first acrylic fibers in 1941 and trademarked them under the name Orlon. As it resembles silk, it is also called artificial silk. It was first developed in the mid-1940s but was not produced in large quantities until the 1950s. 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. Mod acrylic is a modified acrylic yarn.
