FAR INFRARED RAY RADIANT COMPOSITE FIBER

摘要

distributing far-IR radiating ceramics into the thermo plastic linear polymer, e.g. thermoplastic polyamide or polyester linear polymer to make core portion (B); distributing silicon compd. in microparticles state which is extractable by after treatment in the thermoplastic linear polymer, e.g. thermoplastic polyester to make sheath portion (A); composite melt spinning the above polymers; drawing and alkali weight reducing. Among the whole cross-section of resulting fiber, sheath portion (A) occupies 20-80 %, core portion (B) 20-80 % and hollow portion (C) 0-40 %.
