FIBRILLATED ACRYLIC FIBRE

摘要

Fibrillated acrylic fibres which are suitable for oxidation in the form of staple fibres 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. Fibres having a Canadian Freeness valve of 350-500, and a decitex value of 1.2 to 1.7 may be produced.
