Abstract: 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.
Abstract: An object of the present invention is to surely provide a wig with hairs that ensures the desired voluminous feeling. A wig comprises an alternate arrangement, the alternate arrangement including: a first region of a wig base in which a plurality of first hairs having a first curl diameter are implanted, the first hair being an artificial hair or a natural hair; and a second region of the wig base in which a plurality of second hairs having a second curl diameter smaller than the first curl diameter are implanted, the second hair being an artificial hair or a natural hair, the first and second regions being adjacent to each other and alternately arranged.
Abstract: A wig base is disclosed, which comprises a first stretchable net-region with a predetermined width, two non-stretchable net-regions connected to lower right and left sides of the first stretchable net-region, and a second stretchable net-region between the two non-stretchable net-regions. An area of a wearer from “hollow of the neck” to “nucha” is covered mainly by the first stretchable net-region. The two non-stretchable net-regions would be at around the “hollow of the neck” of the wearer without deforming itself. Thanks to the second stretchable net-region existing between the between the two non-stretchable net-regions, the distortion of the wig base can be effectively relieved, and thus, higher fitness of the whole wig base can be obtained.
Abstract: A wig base of the present invention is at least partially made of net-material, and to periphery of which a strip of net-material is attached. The strip has a quadruple constitution, wherein the net-material of the strip is folded double along a folding line, and side edges of the folded net-material is further folded inwardly. The periphery edge of the wig base is covered by the folded strap. There is kept a first space (X) between the folding line of the strip and the periphery edge of the wig base. Thanks to this constitution, the camouflage effect can be given to boundary line between a user's head and the wig periphery, and the tangle of the wig base at its periphery region can be prevented.
