Acrylic was developed by DuPont in 1944 and was first commercially produced in 1950. Acrylonitrile, the substance from which acrylic fibers are produced, was first made in 1893 in Germany and was used as another chemical in research for the DuPont Company. First used for outdoor purposes, technology has allowed acrylic to come a long way, and it is now most commonly used in apparel and carpets. DuPont ceased production of acrylic in 1991, and only a handful of companies produce acrylic today. Acrylic is defined as 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. Acrylic fibers create a fine, soft and luxurious fabric with the bulk and hand of wool Acrylic fibers are produced from a petrochemical called acrylontrile and are dry spun or wet spun. In dry spinning, the polymers are dissolved in a suitable solvent, extruded into warm air, and solidified by the evaporation of the solvent. “After spinning, the fibers are stretched hot, three to ten times their original length, and then crimped, and marketed as cut staple or tow. In wet spinning, the polymer is dissolved in solvent, extruded into a coagulating bath, dried, crimped, and collected as tow . . . or cut into staple.�? Acrylic fibers are usually modified to create special properties best suited for their end-uses and are unique because of their uneven surface. Acrylic has many appealing properties, and the sports world is just one industry that is increasingly taking advantage of them. Acrylic’s high performance is making it one of the fastest growing fibers in the outdoor, performance apparel categories. For example, the NBA and NFL have made acrylic socks part of their official uniforms. Athletes of all types are using acrylic because of its elasticity, shape retention, and moisture control. This fiber draws moisture away form the skin and quickly transports it to the surface making the wearer more comfortable. This wicking capability of acrylic is permanent and in a class by itself compared to other fibers.
