A washibility improver for a textile article, which comprises a reaction product obtained by radical polymerization of at least one monomer selected from the group consisting of acrylic acid, methacrylic acid, maleic acid and salts thereof in the presence of poly- alpha -hydroxyacrylic acid or a salt thereof. The washability improver attains excellent dispersibility-improving, washability-improving, and metal-removing effects and prevents a soil deposition on fibers and machines and a formation of scales. |
