Abstract
A process of producing a vinyl chloride fiber with a small fineness having seven-tenth to half of the full luster surface and feel remarkably similar to human hair is provided. The process provides the vinyl chloride fiber comprising a vinyl chloride resin composition obtained by formulating (a) 1-35 parts by weight of ethylene-vinyl acetate resin, (b) 0.2-5.0 parts by weight of thermal stabilizer, and (c) 0.2-5.0 parts by weight of lubricant to 100 parts of a vinyl chloride mixture consisting of 100-60% by weight of a vinyl chloride resin and 0-40% by weight of chlorinated vinyl chloride resin. The process also provides the vinyl chloride fiber obtained by melt spinning the resin composition described above. The vinyl chloride fiber is useful for an artificial hair fiber for the decoration of hair or a doll's hair fiber such as a doll hair.
