Abstract (en)
Cellulose or acrylonitrile fiber having methacrylic acid or hydroxyalkyl methacrylate graft-copolymerized in an amount of 3-60 % by weight is disclosed. The graft fiber is produced by reacting methacrylic acid or a hydroxyalkyl methacrylate with cellulose or acrylonitrile fiber in an aqueous medium containing hydrogen peroxide and a ferrous salt.
