摘要/Abstract

摘要：

为开发兼具弹性和导电性能的电磁功能纱线,以氨纶为芯丝、外包不锈钢短纤维/棉混纺纱,研制系列弹性不锈钢短纤维/棉包覆氨纶纱。在Instron 5566万能试验机上,结合万用表,获得弹性纱线的应力-应变、应变-电阻以及定伸长弹性回复曲线,研究纱线在不同拉伸状态下的电学性能。结果表明:不锈钢短纤维/棉包覆氨纶芯丝的纱线,存在氨纶芯丝的断裂现象,将不锈钢短纤维/棉包覆氨纶芯丝的纱线直接与氨纶丝或氨纶/棉包芯纱直接并合的方式,赋予纱线弹性;随着不锈钢短纤维含量的增加,弹性纱线的弹性伸长和回复性能都降低,塑性变形增加;随着弹性纱线应变的增加,其电阻先增加后降低。

关键词: 电磁功能纱线, 弹性回复率, 塑性变形率, 电学性能, 导电纱线

Abstract:

In order to develop electromagnetic functional yarns with both elastic and electrical properties, a series of elastic stainless steel fiber/cotton ammonia yarns were developed with spandex as the core yarn and wrapped with stainless steel fiber/cotton blended yarn. On the Instron 5566 tester, combined with a multimeter, the stress-strain, strain-resistance and elongational elastic recovery curves of the elastic yarn were obtained, and the electrical properties of the yarn under different tensile conditions were investigated. The results show that the addition of spandex yarn improves the elastic properties of stainless steel fiber/cotton blended yarn, but the spandex core yarn would fracture easily. When the content of stainless steel short fiber increases, the elastic elongation and recovery properties of elastic yarn decrease, and plastic deformation increases. The strain increases of the elastic yarn, causes the electrical resistance of the stainless steel fiber/cotton ammonia yarn to increase first and then decreases until the yarn breaks, and the maximum value of the resistance occurs when the spandex filament is straight but not elongated.

Key words: electromagnetic functional yarn, elastic recovery rate, plastic deformation rate, electrical properties, conductive yarn
