摘要： An artificial hair bundle (10) is made up by mixing a first artificial hair made of a polyester resin (1, 2) and a second artificial hair made of a polyamide resin (5, 6), and the first artificial hair (1, 2) is made of polyethylene terephthalate and polybutylene terephthalate, having a cross-sectional size and bending rigidity similar to those of natural hair, wherein the bending rigidity is in the range of about 6.5 to 7.8×10−3 gf·cm2/strand at humidity 40%, and the first artificial hair (1, 2) suppresses bundling of the second artificial hair (5, 6), and the first and the second artificial hairs (1, 2, 5, 6) behave similarly to natural hair.

摘要： An artificial hair and a wig using the same are provided which have the property of thermal deformation expanding upon heating by a hair drier or others used for hair styling.The artificial hair 1 is made by mixing at the pre-determined ratio a semi-aromatic polyamide having a glass transition temperature between 60-120° C. and a resin not expanding in said temperature range. The artificial hair may have a sheath/core structure comprising a core portion 5B and a sheath portion covering the core portion. As the resin not expanding in said temperature range, polyethylene terephthalate or others can be used, and as the sheath, nylon 6 or nylon 66 can be used. Said artificial hair 1 can maintain its shape at room temperature or after shampooing due to thermal deformation by heating in steam atmosphere at temperature of glass transition or higher or about 80-100° C.

摘要： A hair material for a wig is preliminarily curled and then bound to a wig base to thereby orient the curled hair in a definite direction. A folded part (10c) of a hair material (10) is penetrated from one side of a filament (15) to the other side under a wig base (12) so that a first loop (17) is formed in the inner side of the folded part (10c). A curved part (10d) is inserted though the first loop (17) so that a second loop (19) is formed in the inner side of the curved part (10d). A part (10b) of the hair material is inserted through the second loop (19). Next, the hair material parts (10a, 10b) are pulled in directions opposite to each other and tied with the filament (15) to (20). Thus, the hair material (10) is bound to the filament (15).
