▎ 摘　　要

NOVELTY - The yarn has a yarn main body provided with yarn core material and formed with a coating layer. The yarn core material is provided with an ultra-high molecular weight polyethylene fibre with intensity range of about 28-52cN/dtex. The core material is coated with a doped phase change material coating layer. The coating layer is provided with base material and phase change material. A substrate is selected from a group consisting of a chemical fiber filament or a short fiber. A heat-conducting material is provided with nanometer graphene, graphite powder and a carbon nano-tube USE - Heat-resistant ultra-high molecular weight polyethylene yarn. ADVANTAGE - The yarn has better high temperature tolerance under high temperature environment, still has high-strength and high-characteristics, can resist high temperature for a long time, and can be used repeatedly, and has industrial practicability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a heat-resistant ultra-high molecular weight polyethylene yarn manufacturing method.
