<p>The present invention relates to a polyvinyl chloride-based resin fiber having a shrinkage stress of 70 µN/dtex or less at 130°C. When fiber bundles for artificial hair which includes 20 to 100% by weight of this polyvinyl chloride-based resin fiber and 0 to 80% by weight of a thermoplastic resin fiber having a Young's modulus of 4 to 9 GPa and a shrinkage percentage of 10% or less at 130°C and having a composition including no polyvinyl chloride-based resin are processed, a fiber for artificial hair and an artificial hair product having an excellent styling property and texture similar to those of human hair can be obtained.</p> |
