Abstract: Fibrillated acrylic fibers which are suitable for oxidation in the form of staple fibers are formed as copolymers of acrylonitrile and an unsaturated carboxylic acid such as itaconic acid or methacrylic acid. A further monomer may also be included, such as methacrylate, methylmethacrylate or vinyl acetate. Fibers having a Canadian Freeness value of 350-500, and a decitex value of 1.2 to 1.7 may be produced.
