A process and apparatus for automatically weighing and introducing chemicals are intended to automatically weigh the chemicals and introduce the chemicals into a treatment tank; the chemicals are injected into a chemical container and weighted, and then transported to a dissolving tank adjunct to the treatment tank, and then introduced into the dissolving tank. A control means is provided to put under its control the operations of injecting into a chemical container a desired amount of desired chemicals selected from among plural sorts of chemicals and driving a transportments and an introducing means automatically in association with this injecting operation.

Durable excellent water absorption property and antistatic property can be given to synthetic fiber by a simple method. In the method, a polymerization initiator is absorbed in the fiber and then the fiber is applied with a water-soluble polymerizable monomer and heat treated to form a polymer thereon.

Method of treating synthetic fibers or synthetic fiber fabrics

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.
