A process for the preparation of a homogeneous spinning solution for the production of acrylic fibers, which includes: preparing an aqueous suspension of homopolymer or copolymer of acrylonitrile through the polymerization of monomers in aqueous suspension, removal of the unreacted monomers, filtration and washing of the aqueous suspension, obtaining a filtration cake; dispersing the filtration cake; and evaporating the dispersion of polymer or obtaining the homogeneous spinning solution.

Process for the production of acrylic fibers

The invention relates to modified materials based on polyacrylonitrile having amidic groups on their surface. The modification gives the material greater hydrophilic characteristics improving its comfort properties. In addition, it permits the polyacrylonitrile to be dyed also with acidic dyes thus making it possible for it to be used for the preparation of yarns mixed with natural fibres, such as wool for example. The process for their production involves treatment of the material with enzymes of the nitrile hydratasis class obtained from Brevibacterium imperiale.
