  • Temperature adaptable textile fibers and method of preparing same
    Patent number: 4908238
    Abstract: Temperature adaptable textile fibers are provided in which phase-change or plastic crystalline materials are filled within hollow fibers or impregnated upon non-hollow fibers. The fibers are produced by applying solutions or melts of the phase-change or plastic crystalline materials to the fibers. Cross-linked polyethylene glycol is especially effective as the phase change material, and, in addition to providing temperature adaptability, it imparts improved properties as to soil release, durable press, resistance to static charge, abrasion resistance, pilling resistance and water absorbency.
