ABSTRACT:
A production method for implanted hair articles including superfine fibers is disclosed in which the tension and nerve are strong, hair falling is eliminated, and a high grade appearance and flexibility are given. Composite fibers composed of fiber-forming polymers of a plurality of components having an identical or different solubilities for a chemical or solvent are processed into piles P, the piles P are subjected to hair implantation on a face of a base material 4 on which an adhesive for hair implantation is applied and are dried, subsequently a chemical reaction suppressing agent 5 for the above-mentioned chemical or solvent is coated on the hair implantation face of the base material 4, and thereafter the above-mentioned chemical or solvent is used to dissolve and treat components having larger solubilities of the piles P, or each of the components is subjected to a peeling treatment, whereby only portions other than roots of the above-mentioned piles P are divided into each of the polymers.
