Acrylic fiber is a synthetic fiber that closely resembles wool in its character. According to the definition of the ISO (International Standards Organization) and BISFA (International Synthetic Fiber Standardization Office), fibers which contain a minimum of 85% acrylonitrile in their chemical structure are called "Acrylic Fibers".
Acrylic fiber is composed of acrylonitrile and a comonomer. The comonomer is added to improve dyeability and the textile processability of the acrylic fiber. Acrylic fiber is produced with two different systems: wet spinning and dry spinning. Acrylic fiber can be supplied as producer-dyed either by pigmentation of the dope or with jel dyeing systems. It can be used 100% alone, or in blends with other natural and synthetic fibers.
The Aksa manufacturing process is based on wet spinning process . The fiber has a kidney shaped cross-section. Aksa produces tow, top or staple fiber in both ecru and in a broad range of colors by gel dying, dope dying and continuous tow dying. Today AKSA has become one of the world’s leading producers of acrylic fiber with a market share of 24%.
