▎ 摘　　要

NOVELTY - The heat-absorbing fiber (100) has a base layer (110) which is made of acrylate-based fibers. An intermediate layer (120) is made of fibers containing ceramic particles formed on the base layer. A check-type graphene laminating line (140) is formed under a metal layer (130) made of silver or aluminum for coating an upper portion of the intermediate layer and a lower portion of the base layer. USE - Hygroscopic heat-absorbing fiber for making clothes such as shirt or trousers. ADVANTAGE - The fiber improves heat retention by absorbing heat from sweat or water vapor generated in human body, has excellent workability compared to reflectance by adopting silver or aluminum as metal layer, and prevents discomfort due to static electricity in winter. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the laminated state of heat absorption and heat fibers.
