Acrylic Fiber

Among the major acrylic fibers used in commerce acrylonitrile is the comonomer containing a cyanide group.

Acrylic fiber. A manufactured fiber in which the fiber forming substance is any long chain synthetic polymer composed of at least 85 by weight of acrylonitrile units ch2 ch cn ftc definition. Acrylic fibers are an important category of man made fibers based on polyacrylonitrile produced by addition polymerization of acrylonitrile vinyl cyanide. Acrylic fiber fabrics are made from a synthetic polymer called acrylonitrile. Acrylic fibers are produced by two basic methods of spinning extrusion dry and wet.

Acrylic fibers are fibers of moderate strength and elongations at break. Dupont created the first acrylic fibers in 1941 and trademarked them under the name. The tenacity of acrylic fibers varies from 2 to 4 g d 18 36 g tex. The elongation at break varies from 20 to 50 for the various acrylic fibers.

On wetting the tenacity drops to 1 5 3 g d 13 27 g tex. Acrylic fiber definition is a quick drying synthetic textile fiber made by polymerization of acrylonitrile usually with other monomers. The acrylic fibers include acrylic modacrylic and other vinyl fibers containing cyanide groups as side chains. Most commercial acrylic fibers are in fact copolymers of acrylonitrile and other vinyl monomers such as vinyl chloride vinyl acetate vinyl alcohol vinylidene chloride acrylic acid.

Acrylic fibers are formed from the wet or dry spinning of copolymers containing at least 85 acrylonitrile units. For a fiber to be called acrylic in the us the polymer must contain at least 85 acrylonitrile monomer typical comonomers are vinyl acetate or methyl acrylate. Acrylic fiber acrylic fiber is a synthetic fiber that closely resembles wool in its character. This type of fiber is produced by reacting certain petroleum or coal based chemicals with a variety of monomers which means that acrylic fabric is a fossil fuel based fiber.
