What is polyester industrial yarn


Polyester industrial yarn refers to high-strength, coarse-denier polyester industrial filament, and its fineness is not less than 550 dtex. According to its performance, it can be divided into high-strength and low-stretch type (ordinary standard type), high-modulus low-shrinkage type, high-strength low-shrinkage type, and active type. Among them, high-modulus low-shrinkage polyester industrial yarn has a tendency to gradually replace ordinary standard polyester industrial yarn in tires and mechanical rubber products due to its excellent properties such as high breaking strength, high elastic modulus, low elongation, and good impact resistance. ; High-strength and low-elongation polyester industrial yarn has the characteristics of high strength, low elongation, high modulus, and high dry heat shrinkage. It is mainly used as tire cord, conveyor belt, canvas warp, and vehicle seat belts and conveyor belts; Low-shrinkage polyester industrial yarn has little shrinkage after being heated, and its fabric or woven rubber products have good dimensional stability and heat resistance stability, can absorb impact loads, and have the characteristics of nylon softness, mainly used for coated fabrics (advertising light box cloth, etc.), conveyor belt weft, etc.; active polyester industrial yarn is a new type of industrial yarn, which has a good affinity with rubber and PVC, which can simplify the subsequent processing technology and greatly improve the quality of the product.
