由刨花金属短纤维制备技术用金属纱线

Metal spun yarns from planed metal staple fibers for technical applications

目前,德国纺织机械和高性能材料技术研究所(ITM)正对刨花金属短纤维纺制纱线的工艺过程进行广泛的调查研究。为顺利纺纱,必须考虑这类纤维的高耐磨性、高脆性和高刚性等特性,以及它们较高的塑性变形和粘滑运动倾向。基于传统成纱工艺,开发出以刨花金属短纤维为原料,经拉伸断裂、牵伸和纺纱过程制备纯金属纱线的纺纱工艺链。基于目前的研究,由刨花金属短纤维制备纯金属纱线的可行性已得以证实。所得金属纤维在高性能、低成本技术应用方面具有较高的潜力。

Currently,extensive investigations are being performed at the Institute of Textile Machinery and High Performance Material Technology(ITM)to gain profound insight into the yarn formation process based on planed metal staple fibers.For this purpose,the special properties of these fibers such as high abrasiveness,high brittleness and high rigidity,in addition to their strong high tendencies for plastic deformation and stick-slip motions are considered.The developed process chain based on the conventional yarn formation process consists of stretch breaking,drafting,and spinning of 100%metal spun yarns from planed metal staple fibers.According to the current developmental state,functionality of the yarn formation process from 100%planed metal staple fibers is regarded as proven.Thus,a high potential of utilizing these fibers for high-performance and cost-efficient technical applications clearly exists.
