Phase change materials incorporated throughout the structure of polymer fibers

摘要

The present invention is directed to a fiber composition comprising a fiber forming polymer and a phase change material integrally incorporated throughout the fiber forming polymer which is either a polyalkylene oxide, polyalkylene ether or mixture of various polyolefins. The phase change material has a melting temperature between about 15 DEG C. and about 65 DEG C. The fiber composition can be used as a loose fill insulating material for use in clothing or bedding articles or can be formed into a fabric for the same uses.
