Acrylic fibers are artificial fibers is made out of artificial linear polymer that consists of a minimum of 85% (m/m) of acrylonitrile models or acrylonitrile copolymers. Acrylonitrile the bottom element for acrylic fiber is a product of the petroleum trade. The fiber is produced by dissolving the polymer in a solvent corresponding to N, N-dimethylformamide or aqueous sodium thiocyanate, metering it via a multi-hole spinnerets and coagulating the resultant filaments in an aqueous answer of the identical solvent. The processing is accomplished with washing, stretching, drying and crimping. Acrylic fibers are both moist or dry spun.

Manufacturing of acrylic fibers is centered within the Far East. China has emerged as a number one producer on the planet accounting for nearly 1 / 4 of world capability. China has manufacturing capability at 900 thousand tons in 2005 which has grown by 50% since 2000. China can also be a significant shopper of acrylic staple fiber. Japan, alternatively, shares simply 9.5% of world capability which has been constantly dropping whereas Turkey has maintained its world share at 7.8% within the final 5 years.
In 2005, world manufacturing of acrylic staple fiber touched 2,791 thousand tons. Acrylic accounts for 8% of all chemical fiber produced on the planet. Over the last 5-year interval ended 2005, Acrylic staple fiber manufacturing has elevated at a fee of 1.25% every year, the slowest progress fee amongst all chemical fibers manufacturing. Within the yr 2005 192,000 tons of acrylic fibers had been produced in Germany.
In 2005, the acrylic fiber trade was adversely affected by rising uncooked materials value. Acrylonitrile was dearer by nearly 22-23% in USA, 16-17% in Europe and by 20% in Asia throughout 2005. Throughout this time, acrylic staple fiber costs elevated at a slower tempo. They had been up 15% in USA, 4% in Europe and 3-5% in Asia.
Thai Acrylic Fibre Co., Ltd., a subsidiary of the Adyta Birla Group of Industries, is likely one of the main acrylic fiber producers on the planet. In Europe, Bayer was the primary producer, since 1954 has been manufacturing on a big scale.
