After the po1ypropylene fiber successfully used into the cement concrete ,polyester fiber is a new-developed engineering material in recent years.With polyester as its raw material, the fiber is produced through adding some functional additive , by plastic  melting,extruding,high-

ratio stretching and special surface disposal.And shaped by cutting with special machine Its appearance is beam-like structure with many monofilament fiber collecting.
Besides the small thinness,high tensile strength and easily scattering,polyester has good heat-resistance.It can be used in hot-mixing bitumen concrete projects and reinforced crack-resistance for high-tensile concrete,so it is an ideal multi-functional reinforced material.
According to the testing report by  many authorized organizations,the polyester fiber's main technological performance indexes all reach the advanced level of the same products in the world.
