POLYVINYL CHLORIDE FIBER REDUCED IN INITIAL COLORATION

摘要

Polyvinyl chloride fibers having satisfactory transparency and reduced in initial coloration although the fibers are ones formed from a composition comprising a vinyl chloride resin and a chlorinated vinyl chloride resin in combination in order to obtain heat-resistant polyvinyl chloride fibers and containing a metal soap stabilizer. The invention is characterized by adding a specific amount of a ß-diketone to a composition which comprises a combination of a vinyl chloride resin and a chlorinated vinyl chloride resin and has been stabilized with a stabilizer comprising a metal soap and a hydrotalcite.
