不同种类的UHMWPE/R复合纱织物力学及防刺性能对比

Comparison of mechanical and puncture-proof properties of different typesof UHMWPE/R composite yarn fabrics

文章选用由UHMWPE及黏胶纤维所纺制的相同线密度UHMWPE短纤纱/R、UHMWPE长丝/R包芯纱,UHMWPE短纤纱/R、UHMWPE长丝/R赛络菲尔纱4种不同种类的UHMWPE/R复合纱,分别织制相同规格平纹织物,并对其进行力学及静态防刺性能的测试对比。结果表明:各试样的拉伸断裂强度其纬向都略大于经向,而撕裂强度则相反。纱线的结构及物理性能在很大程度上影响了织物的力学性能。各试样的经向穿刺力略大于纬向,而沿试样45°方向的穿刺力都小于经纬向,且各试样中织物强力较高的普遍穿刺力较高,织物中毛羽的提高也有利于穿刺力的提高。

This article selects four kinds of UHMWPE/R composite yarns with the same linear density,namely,UHMWPE staple yarn/R,UHMWPE filament/R core-staple yarn,UHMWPE staple yarn/R,UHMWPE filament/R Sirofil yarn spun by UHMWPE and viscose fiber,to weave plain weave fabrics with the same specifications,and their mechanical properties and static puncture-proof properties were tested and compared.The results indicate that the tensile breaking strength of each sample is slightly greater in the weft direction than in the warp direction,while the tearing strength is the opposite.The structure and physical properties of yarn greatly affect the mechanical properties of fabric.The puncture force in the warp direction of each sample is slightly greater than that in the weft direction,while the puncture force at an angle of 45°with the sample is smaller than those in the warp and weft directions.Among all samples,the puncture force is generally higher for fabrics with higher strength and the improvement of hairiness in fabrics is also beneficial to the improvement of puncture force.
