Artificial hair and wig using the same

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.

主权项

1. An artificial hair consisting of a sheath/core double filament structure comprising a core portion and a sheath portion covering said core portion, wherein
said core portion consists of polyethylene terephthalate and a semi-aromatic polyamide resin mixed together, the polyethylene terephthalate having a concentration of 3-30 weight % in the core portion, said semi-aromatic polyamide resin having glass transition temperature between about 60-120° C., said semi-aromatic polyamide resin being an alternate copolymer of metaxylylene diamine and adipic acid and said sheath portion is made of a polyamide resin having lower bending rigidity than said core portion.
