聚酯纤维纱/撕裂线 POLYESTER YARN
聚酯纤维纱采用*优质纤维原料，具有强度高、热收缩率低、体积小，不吸潮，耐高温等特点。主要用于电线电缆和光缆的填充，使线缆达到圆整。同时可以增加线缆抗拉强度与弯曲性能，还可以用于线缆外线编织。
Polyester fiber yarn is made of the best fiber materials, with high strength, low thermal shrinkage, small size, no moisture absorption, high temperature resistance and other characteristics. It is mainly used for filling wire and cable to make the cable round. At the same time, it can increase the tensile strength and bending performance of the cable, and can also be used for cable outside braiding.

撕裂绳又称撕裂线，由多股高强度聚酯纱加捻而成,起到增加电缆拉伸强度,也可以起到撕裂护套的作用。
Tear cord, also known as tear line, is made of multiple strands of high strength polyester yarn, which can increase the tensile strength of the cable and also play a role in tearing the sheath.
