[Solutia, Inc. (formerly Monsanto)] A registered trademark for an acrylonitrile-vinyl acetate copolymer fiber that is commonly used in textiles. Acrilan® was first produced in 1949 by Chemstrand Corp. After slight changes in the formulation and manufacturing procedures, Acrilan® was first commercially manufactured in 1954. It is an Acrylic fiber copolymerized with less than 15% vinyl acetate groups. Acrilans are noted for softness, strength and wrinkle-resistant properties. Acrilan® is used for clothing, carpets, drapes, upholstery and laminates. Its wear resistance is better than that of wool, but generally greatly inferior to that of nylon or Terylene. It is unaffected by mildew, molds, moth and carpet beetle larvae.
In 2003, Solutia went into bankruptcy and reorganized. The Acrilan production plant closed in 2020.
