▎ 摘　　要

NOVELTY - The polyester has a hollow polyester fiber, a wheat straw fiber and a graphite fiber connected with each other. The wheat straw fiber and the graphene fiber are provided with a hollow part of the hollow polyester fiber, where denier of the polyester fiber and graphite fiber is about 150 deniers and 50 deniers respectively. USE - Heat-insulating radiation-resistant polyester. ADVANTAGE - The polyester has better insulating performance and heat preservation and anti-radiation effect, and avoids grease and provides the wheat straw fiber with better heat preservation effect, the graphene fiber with high strength and the wheat straw fiber with sufficient length. DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of a heat-insulating radiation-resistant polyester.
