Abstract
Fibres formed from an acrylonitrile polymer are treated to make them suitable for use in the manufacture of paper by reducing them p to staple lengths, immersing them in an aqueous solution of an oxidizing salt, to partially disrupt them, washing and drying them. They may then be beaten in an aqueous dispersion and formed into a sheet or web. The polymer may be polyacrylonitrile, a binary or ternary copolymer containing at least 80% by weight of acrylonitrile or a blend of polyacrylonitrile or such copolymers with another polymeric material, the blend having an overall content of polymerized acrylonitrile of at least 80% by weight. The oxidizing salt is a bichromate, hypochlorite, permanganate, persulphate or perborate of an alkali metal or ammonia.
