PURPOSE:To obtain a cationic regenerated cellulose product excellent in reactivi ty with an anionic dye or an anionic compound and adsorptivity for them by mixing a viscose with a bis(quat. ammonium salt) polymer. CONSTITUTION:A viscose is mixed with a polymer based on a monomer having two quat. ammonium groups (e.g. an acrylic monomer of the formula), desirably a bis(quat. ammonium salt) polymer of a viscosity of about 100 to 20000cP when determined in a 25wt.% aqueous solution at 30 deg.C, and the mixture is formed into a cationic regenerated cellulose product such as a cotton, yarn, cloth or the like of viscose rayon. The amount (in terms of the solid matter) of the bis(quat. ammonium salt) polymer mixed is 0.5 to 50wt.%, desirably 5 to 20wt.% based on the dry weight of the cellulose in the viscose solution. |
