摘　　要：为了制备防切割织物,以氨纶长丝为芯纱,超高分子量聚乙烯(UHMWPE)短纤和不锈钢(SSF)短纤混纺为外包纱纺制包芯纱,选择SSF纤维含量、成纱捻系数和氨纶丝预牵伸倍数为因素,设计三因素五水平正交试验,并以纱线的毛羽数、断裂强力、弹性回复率以及所织织物的切割力为主要质量评价指标,研究了SSF纤维含量、成纱捻系数和氨纶丝预牵伸倍数对所织织物防切割性能和舒适性的影响。试验结果表明:包芯纱的最优工艺参数为SSF纤维含量40%、成纱捻系数350、氨纶丝预牵伸2.8倍;纱线毛羽数、弹性回复率与织物防切割性能未见明显相关关系,断裂强力与织物防切割性能呈负相关关系;SSF纤维含量是影响织物防切割性能的主要因素,成纱捻系数和氨纶丝预牵伸倍数对其影响不显著。认为:按照优选后工艺纺制的UHMWPE/SSF氨纶包芯纱,其织物具有良好的防切割性能。In order to prepare anti-cutting fabric,spandex filament was used as core yarn,ultra high molecular weight polyethylene(UHMWPE)staple fiber and stainless steel(SSF)staple fiber were blended as outer fiber to spin core-spun yarn.Three-factor five-level orthogonal test was designed by selecting SSF fiber content,yarn twist factor and pre-drafting ratio of spandex as factors.Hairiness,breaking strength,elastic recovery rate and cutting force of the woven fabric as the main quality evaluation indexes.Effects of SSF fiber content,twist factor of the yarn and pre-drafting ratio of spandex on anti-cutting property and comfort of the woven fabric were studied.The test results showed that the optimum process parameters of core-spun yarn were 40%SSF fiber content,350 twist factor and 2.8 times pre-drafting ratio of spandex.There was no obvious correlation among yarn hairiness,elastic recovery rate and the anti-cutting property of fabric,but the breaking strength was negatively correlated with the anti-cutting property of fabric.The content of SSF fiber was the main factor affecting the anti-cutting property of fabric,the twist factor and the pre-drafting ratio of spandex had no significant effect on it.It is considered that the fabric of UHMWPE/SSF spandex core-spun yarn according to the optimized process has better anti-cutting property.
