How is acrylic fibres manufactured?
Answers
ACRYLIC FIBER
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.Aksa Process
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 13.2%.
Properties of Acrylic Fiber
Easy to wash and good dimensional stability.
Resistance to damage by moths and chemical substances.
Excellent color-fastness and dyeability in brilliant colors.
Highly resistant to sunlight.
Lightweight, soft, and warm, with a wool-like touch
End Uses of Acrylic Fiber:
Apparel: Sweaters, socks, fleece wear, circular knit apparel, sportswear and childrens wear
Household Textiles: Carpet, blankets, area rugs, upholstery, pile fabrics
Outdoor end uses: Car tops, boat covers, awnings, outdoor furniture
Industrial end uses: Filtration materials, reinforcement materials in construction, car batteries
Answer:
Acrylic fiber is a synthetic or man-made fiber that is made from a polymer called polyacrylonitrile (the monomer of this polymer is acrylonitilre). It is primarily manufactured by two methods- wet and dry spinning. The fibers are first dissolved in a suitable solvent and then spun so that they are solidified. In dry process, warm air is used to evaporate the solvent. In wet process, a coagulating substance is used to solidify the fiber and then it is dried.
