| titleOfInvention | Artificial hair and its processing method |
| abstract | An artificial hair which comprises a fiber prepared from an acrylic polymer comprising 40 to 74 wt% of acrylonitrile, 25 to 59 wt% of vinylidene chloride and 1 to 5 wt% of a sulfonic acid group containing vinyl monomer copolymerizable with above monomers and having a gloss contrast of 0.88 or more, a knot strength of 0.5 cN/dtex and an average fineness of a single fiber of 30 to 1000 dtex; and a method for producing the artificial hair which comprises incorporating 5 to 20 parts by weight of water into 100 parts by weight of a polymer solution comprising the above acrylic polymer and a good solvent to prepare a spinning stock solution, subjecting the stock solution to a wet spinning to prepare a fiber, subjecting the fiber to a stretching treatment by a factor of 2.5 to 12, and then to a softening treatment by a softening percentage of 15% or more. The artificial hair is improved in processability, such as hair cutting in a machining step in manufacturing a tress or during setting the hair to the skin in manufacturing a wig or toupee. |
