Acrylic fiber was first created by DuPont in 1941 under the trade name Orlon. It began large scale production in the 1950s. Acrylic fiber is made from acrylonitrile monomer which is derived from acetylene and hydrogen cyanide. The monomer undergoes polymerization with co-monomers like vinyl chloride or methyl acrylate. The manufacturing process involves the polymerization of acrylonitrile followed by extrusion to form fibers. Acrylic fiber has good elastic recovery, is resistant to chemicals and sunlight, retains warmth well and is easy to dye. It is used for clothing, home furnishings, industrial applications, and other uses.

13.  Acid: It has good resistance to mineral acid.
 Alkali: The resistance to weak alkali is fairly good but hot strong alkali damages
this fiber.
 Solvent: It has excellent resistance to common solvents, oils, greases, and natural
salts.
 Water: moisture regain of this fiber varies from 1.5% to 3%. Easy to wash and
quick drying.
 Effect of heat and sunlight:
 This fiber has very good thermal stability. Safe ironing temperature is at 1600C. At
230 – 2350C acrylic sticks with the iron i.e. melting occurs. High temperature may
sometime causes yellowing of this fiber.
 Effect of Biological agents
 This fiber is unaffected by mildew, molds, laves and insects.
