Title: Acrilan® (Solutia)
Literature References: A brand of acrylic fiber, a copolymer of acrylonitrile and of a minor constituent with mildly basic character. Prepn of such copolymers: Mowry, Craig, US 2744086 and Craig, US 2749325 (both 1956 to Chemstrand). Review: R. W. Moncrieff, Man-Made Fibres (John Wiley & Sons, New York, 4th ed., 1963) pp 471-482.
Properties: Solid, d25 1.17. Fiber decomposes before it melts. Sticks at 245°. Prolonged exposure in air at elevated temps causes some yellowing. Fabrics are not readily ignited and their rate of burning is less than that of cotton, viscose rayon, or acetate rayon. Fiber is practically insoluble in, and unaffected by common solvents. Has fairly good resistance to weak alkalies, very good resistance to mineral acids, sunlight, weathering. Has good dyeing properties. 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.
Density: d25 1.17
Use: Fabrics, sweaters, blankets, carpets.
