  • Publication number: 20090126753
    Abstract: An adhesive for a wig, a wig using the same, and methods of manufacturing the both are such that the adhesive for a wig has a single layer, is bondable unpeelably to the inner side of a wig base, and is bondable by pressure re-peelably to scalp, wherein the adhesive layer (4) is provided to fix needle foot portions of hair (3) penetrated to the inner side of the wig base (2). One side of the adhesive layer (4) is bondable by chemical reaction to the inner side of the wig base (2) during gelation reaction of the adhesive solution applied to the inner side of the wig base (2), while the other side is bondable by pressure re-peelably to scalp. One side of the adhesive layer (4) has the hair fixing function to fix the needle foot portion of hair (3A) planted penetrating the inner side of the wig base (2). Since the wig (1) is made as double layer structure with a single adhesive layer (4), it is light-weighted, and since the adhesive layer (4) has re-peelability, it can be used repeatedly, resulting in low cost.
