<p>An artificial hair made of a fibers comprising a poly- alpha -amino acid derivative insoluble to water and alcohols and represented by one of the following general formulae (1) - (4): <CHEM> providing that R in each of the above formula (1) - (4) is R<a>, R<b> and R<c> represented, respectively, by the following general formula (5), (6) or (7): &lparstr& CH2)kCONR<1>(CH2)lNR<2>R<3> (5), &lparstr& CH2)kCONR<1>(CH2)lSR<2> (6), &lparstr& CH2)kCOOR', H, R' or -CH2CH2SMe (7), or made or polyamino acid urethane fiber comprising a copolymer of an amino acid N-carboxy anhydride and a polyurethane, in which the copolymer is subjected to an amidation reaction with an organic diamine and an organic amine having amino groups and mercapto groups or disulfide groups and to shaping into a fibrous form. The artificial hair has a dyeability, shape retainability, natural and soft and flexible feeling, excellent tough and brushing property, as well as has natural color and gloss and toughness like that natural protein fiber.</p> |
