经编用短纤纱技术研究

Status of Staple Fiber Yarn Technology for Warp Knitting

阐述当前我国短纤纱经编产品研究现状,为适应经编设备及产品性能要求,研究经编对短纤纱成纱质量要求,从纱线断裂强度、捻度、表面毛羽和延伸性能等方面进行测试。进一步从纺纱方式、前处理技术和经编织造3个方面分析短纤纱经编产品生产技术中的问题并提出解决方法。再以棉纱在经编产品开发中实际应用为例,分析了短纤纱经编产品应用现状;结合我国经编行业目前所面临应用形势及迫切生产需求,预测短纤纱经编产品逐渐向多样化、高档化和功能化的发展趋势。

The current research situation of staple fiber yarn warp knitted products in China is described in order to meet the requirements of warp knitting equipment and product performance,and the requirements of warp kniting on the yarn quality of staple fiber yarn are studied,and the yarn breaking strength,twist,surface hairiness and elongation are tested as well.The problems in the production technology of staple fiber yarn warp kntting products are further analyzed from three aspects of spinning mode,pretreatment technology and warp knitting,and the solutions proposed by experiments are also analyzed.Taking the actual application of cotton yarn in the development of warp knitted products as an example,the application status of staple fiber yarn warp kntted products is analyzed.Combined with the current application situation and urgent production demand of warp knitting industry in China,the development trend of staple fiber yarn warp knitted products towards gradual diversification,high-grade and functionality is predicted.
