Abstract
A temperature-sensitive color-changeable composite fiber comprising a phase-(A) thermochromic resin phase formed of a polyolefin resin in which a thermochromic material and an adhesive resin having a molecular weight of 200 to 10,000 or a copolymer resin of an olefin with a unit monomer capable of forming a polymer having a solubility parameter (SP value) of 9.0 or more have been dispersed or dissolved, and a phase-(B) resin phase selected from nylon 12, a copolymer nylon, polyhexamethylene terephthalate and a saturated aliphatic polyester; the phase-(A) and the phase-(B) being joined to each other. This fiber can satisfy the glossiness and touch of fibers, and color changes caused by temperature changes can clearly be sighted thereon. It also can enhance commercial value of various fiber materials and that of wigs for doles and so form, making use of such a fiber.
