摘要：

为降低高性能纤维防刺织物的成本,改善产品的舒适性,通过将芳纶、超高分子量聚乙烯纤维与涤纶进行复合纺纱并制备防刺织物,测试分析了复合纱线基织物以及铺叠层数等对其静态防刺、透气和透湿性能的影响。结果表明:织物穿刺载荷随着面密度的增加而增加,复合纱中引入涤纶可保持或提高织物的防穿刺性能;增加复合纱线织物堆叠层数,织物刺破载荷值最大提升536%;通过增加纤维根数可在较低铺叠层数下达到相当程度的穿刺载荷;加入复合纱后,织物的透湿性和透气性无明显变化;多层织物堆叠对织物透气性有明显影响,随织物经纬密增大,堆叠后织物透气率下降,最大为64.82%。

Abstract:

In order to reduce the costs and improve comfortability of puncture-resistant fabrics made from high performance fibers, the compound yarn with aramid or ultrahigh molecular weight polyethylene fiber (UHMWPE) and polyester were prepared and used as the yarn materials of puncture-resistant fabrics. The influence of compound yarn, fabric density and overlying layers on static puncture properties, air and moisture permeability of fabrics were measured and analyzed. The results show that the puncture force increases with the increase in fabric areal density, and the addition of polyester fibers either maintain or improve the puncture resistance of the fabrics. By increasing the fabric layers, the maximal load improvement is close to 536%. In addition, the puncture load could be achieved by increasing fiber content with small fabric layers.The addition of compound yarn has no influence on air and moisture permeability of the fabrics. However, the air permeability are significantly decreased with overlying layers to 64.82% with the increase of fabric warp and weft densities.

Key words: puncture-resistant fabric, compound yarn, static puncture, aramid, ultrahigh molecular weight polyethylene fiber, polyester, high performance fiber
