    Abstract: A new, pulp-like, acrylic short fiber having excellent heat- and chemical-resistance is provided. The fiber has a thickness distribution of 0.1 .mu.m to 50 .mu.m, a length distribution of 1 mm to 20 mm, and a thermal transition temperature (Tg) of above 200.degree. C. The fiber is produced by heating a mixture of polyacrylonitrile and water of about 5% to 100% by weight to temperatures above hydration-melting temperature under seal to an amorphous melt; cooling the resulting amorphous melt to temperatures between the melting and the solidifying temperatures of the melt to form a supercooled melt; extruding the resulting supercooled melt to give extrudates; heat-stabilizing the resulting extrudates at temperatures between 180.degree. C. and 300.degree. C. for 1 minute to 4 hours after drying and drawing; and cutting and beating the resulting heat-stabilized extrudates into an appropriate size.

    Abstract: Disclosed is an acrylic fiber composed of an acrylonitrile homopolymer or copolymer whose surface consists of particulate and/or microfibrillar structures having a width of 0.01 to 0.5 .mu.m and a length of 0.05 to 10 .mu.m and fibrillar structures formed by aggregation of the particulate and/or microfibrillar structures and having a width of 0.1 to 10 .mu.m and a length of at least 50 .mu.m. The fiber is prepared by spinning a dope of an acrylonitrile homopolymer or copolymer in a solvent at a draft ratio of at least 5 into a coagulating bath comprising a solvent and a coagulant and having a composition such that a skin layer is not formed on the coagulated fiber; taking up the coagulated fiber from the coagulating bath so that the retention time in the coagulating bath is within 60 seconds; and then drawing the fiber in a drawing bath comprising a solvent and a coagulant and having a coagulating property to the dope and a composition such that a skin layer is not formed on the fiber.
