Acrylic Fiber
Acrylic fibers are synthetic materials made from polyacrylonitrile (PAN) fibers, which contain at least 85% of the acrylonitrile monomer. Typically, other chemicals are used with acrylonitrile, such as vinyl acetate or methyl acrylates (making up the remaining 15%).
In order to make the acrylic strands, the polyacrylonitrile fiber is dissolved in a solvent such as N,N-dimethylformamide or aqueous sodium thiocyanate, and then metered through a multi-hole spinnerette. Once formed, the acrylic fiber is washed stretched and and ultimately used in carpet and clothing production.
