Description
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 (Federal Trade Commission definition). Acrylic fibers were first commercially manufactured in 1950 by DuPont as the product Orlon®. The Acrylic resin is dissolved in a solvent, then extruded through spinnerets to produce long, continuous filaments. The smooth, Thermoplastic fibers are resistant to wrinkles, chemicals, UV light, Weathering, insects, Mildew, and moisture. They produce fabrics that are non-allergenic, lightweight, soft, durable and fast drying. They are, however, susceptible to heat and will melt or burn. Acrylic fibers are used for carpets, blankets, drapes, outdoor products (awnings, geotextiles, etc) and apparel such as sweaters, coats, linings, hosiery, dresses, and shirts.
