Procedure for the obtaining of acrylonitrile polymer fibers, which have applications for the manufacture of easy tissue fabrics. It consists of the yarn of a polymer of acrylonitrhyl containing at least 85% of acrylonitrhyl and the rest one or more copolymerizable monomers, free of functional groups, which serve from acid coloring points in the fiber; the polymer has a molecular weight of 40,000-50,000 and terminal groups containing derivatives of the reducing component of a redox system constituted by bisulphite and a composite soluble mercapto in water.
