Abstract
Acrylic synthetic fibers having excellent touch and luster properties are produced, wherein such fibers are prepared from a copolymer comprising 30 weight % or more of acrylonitrile, 70 weight % and less of vinyl chloride and/or vinylidene chloride and from 0 to 10 weight % of other polymerizable vinyl monomers. The copolymer also contains at least one metallic compound which is present in an amount of from 0.1 to 8.0 parts per 100 parts of copolymer and, additionally, at least one cellulose derivative which is present in an amount from 1.0 to 8.0 parts per 100 parts of the copolymer. Fibers produced from such copolymer have the touch and luster very similar to natural animal hair.
