PURPOSE: To provide a processing method for polymer fibers and their fibrous structure to permanently improve an antistatic property, hygroscopic property, dye-affinity, stain releasing property, adhesion between fibers and bondability of the polymer fiber and the fibrous structure.
CONSTITUTION: The improvement of the polymer fibers having an active hydrogen atom by processing comprises (a) forming a single molecular monomer addition on the filament free from substantial graft polymerization of the monomer by bringing the surface of the fibers into uniform contact with an aqueous solution of at least one kind of unsaturated monomers having concentration enough to disperse and penetrate homogenously in a bundle of fibers, and pH≤7, at 75-100°C, (b) starting the graft polymerization of the monomer on the fibers by adding a polymerization initiator of the monomer, and (c) continuing the graft polymerization on the fibers until a sufficient amount of the graft polymer produced to modify the surface properties of the filaments.
