摘要
文章针对4.2 tex长绒棉专纺纱细纱工序中粗纱及细纱自然断头率偏高的问题,通过原料性能分析、工艺参数调整及设备状况检验,发现对于马克隆值较大、长度较短的长绒棉,粗纱的捻系数应偏大掌握,且其值需根据原料的质量变化进行调整。对于超细特长绒棉专纺纱,粗纱定量偏重,细纱的牵伸倍数过大是导致自然断头率偏高的主要原因。
The paper addresses the problem of higher natural breakage in the spinning process of 4.2 tex long-staple cotton yarn. By analyzing the properties of raw material, adjusting process parameters and inspecting the condition of equipment, it is found out that for long-staple cotton with higher Micronaire value and shorter length, higher number of twists should be applied to the roving and the number of twists should be adjusted in accordance with the change of material quality. For specially-spun ultrafne long-staple cotton yarn, high roving weight per unit and high drafting ratio of spun yarn make major contribution to high natural breakage.
