what is polyacrylic fabric
Acrylic fibers are synthetic fibers made from a polymer (polyacrylonitrile) with an average molecular weight of ~100,000, about 1900 monomer units. For a fiber to be called acrylic in the U.S, the polymer must contain at least 85% acrylonitrile monomer.Typical comonomers are vinyl acetate or methyl acrylate.trong 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.
