Polypropylene fiber with auto temperature control, manufacturing method of the same, and fabric prepared from the same

摘要

PURPOSE: A method for preparing polyolefin fiber with function of controlling temperature is provided to prevent rapid change of body temperature and to be used as a material for sportswear and alpine clothing. CONSTITUTION: A polyolefin fiber with function of controlling temperature contains polyolefin resin and phase change material. The phase change material is dispersed in polyolefin resin. The melting point of the phase change material is 25-45°C. The phase change material is paraffin wax. The poly olefin resin is polypropylene resin. The isotactic index of the polyolefin resin is 95% or more.
