TREATING OF FIBER OR FIBER STRUCTURE

摘要

A novel process for imparting durable antistatic and hygroscopic properties together with an excellent hand to fibers comprised of a high polymer having active hydrogen atoms in its molecule or fibrous structures made thereof is provided. The process is performed by heat treating such fibers or fibrous structures in the presence of a treating solution comprising at least one water-soluble vinyl monomer, acid and water. When the fibers impregnated with the solution are heated, the water-soluble vinyl monomers are graft polymerized with the fibers. The fibers are considered to act as a polymerization initiator, so that the graft polymerization reaction according to the present invention, different from conventional processes, can be effected without the aid of any polymerization initiators such as persulfates or peroxides.
