汉麻棉精梳涡流纱的开发

Development of Hemp Cotton Combed Vortex Yarn

为开发汉麻棉精梳涡流纱,对比了汉麻与苎麻、亚麻及棉纤维的性能指标、截面结构,阐述了汉麻纤维的性能特点,运用涡流纺纱技术纺制汉麻棉混纺精梳纱。通过汉麻预处理,正确选择原料混和工艺,合理配置前纺各工序及涡流纺纱机工艺参数,成功纺制出汉麻/棉60/40 21.6 tex混纺精梳涡流纱,且成纱毛羽较环锭纱得到大幅度降低。认为汉麻棉精梳涡流纱具有较好的开发前景,应进一步改进工艺,提高成纱强力和制成率,降低生产成本,方能更好地满足产品开发的需求。

To develop hemp cotton combed vortex yarn, property index and cross section structure of hemp, flax and cotton were contrasted. Property of hemp was introduced. Vortex spinning technology was used and hemp cotton blended combed yarn was spun. Hemp was pretreated, raw material and blending processing were selected correctly, processing parameters in fore-spinning process and vortex spinning were set rationally,hemp/cotton 60/40 21.6 tex blended combed vortex yarn was spun successfully. Hairiness was reduced greatly. It is considered that the development prospects of hemp cotton blended combed yarn is better, the processing should be modified farther, yarn strength and finished product rate should be increased and production cost should be reduced,demands of product development can be reached well.
