A process for producing regenerated collagen fiber from solubilized collagen including adjusting a degree of swelling of solubilized collagen to 100 to 300% and then treating the resulting solubilized collagen with an aqueous solution of a metallic salt. The regenerated collagen fiber has excellent water resistance and undergoes no waving on contact with water.

Process for producing regenerated collagen fiber

The present invention discloses a flame-retardant acrylic synthetic fiber comprising acrylonitrile and a vinyl monomer copolymerizable therewith and containing a finely divided inorganic tin compound. The fiber has high flame retardancy, outstanding gloss and transparency, and satisfactory whiteness and dyeability.

Flame-retardant acrylic fibers and process for preparing same

A copolymer comprising (a) vinyl chloride or a mixture of vinyl chloride and a monomer copolymerizable therewith and (b) 1,2-polybutadiene oligomer and/or epoxidized 1,2-polybutadiene oligomer. The plasticized copolymer can be molded into soft moldings having a low compression set and high tensile and tear strenghts. Also, by the incorporation of the copolymer into vinyl chloride homopolymer or copolymers, hard moldings having delustered surface can be obtained without conducting delustering operation.
