The fiber has a soft, smooth feel which is very similar to wool, and is lightweight. It is often used to create plush velvets, and dyes beautifully. What is Acrylic Fibers? Acrylic can be thought of as artificial wool. It is made from the unlikely combination of coal, air, water, oil and limestone. DuPont first made acrylic fibers in 1944 and began commercial production in 1950. It is spun by either dry spinning or wet spinning. In dry spinning the dissolved polymers are extruded into warm air. The fibers solidify by evaporation. In wet spinning the polymer is dissolved and extruded into a bath and then dried. In some ways, acrylic imitates wool. It has wool's warmth and softness, but does not absorb water. Instead, acrylic wicks moisture to the surface where it evaporates. Acrylic is used in knitted apparels such as fleece, socks, sportswear and sweaters. It is also used to create fake fur, craft yarns, upholstery fabric, carpet, luggage, awnings, and vehicle covers. The acrylic fibers include acrylic, modacrylic, and other vinyl fibers containing cyanide groups as side chains. Among the major acrylic fibers used in commerce, acrylonitrile is the comonomer containing a cyanide group.
