在棉纺设备上纺制毛型纤维的探索

Spinning wool type fiber on cotton spinning equipment

为实现在棉纺织设备上纺制多种纤维长度的粗纱,对TJFA458A粗纱机进行改造：更换中罗拉承座、增加上清洁支撑板调量、将下清洁改为消极式清洁等.并给出了不同长度纤维的纺制方案,以38-51 mm、85 mm改性涤纶/粘胶纤维的试纺为例验证了新型粗纱机的纺纱效果.结果表明：研制的粗纱机可纺制多种纤维长度的粗纱;控制牵伸比滑溜牵伸的纺纱质量好.

In order to spin the wool type fiber on cotton spinning equipment,the fly frame of TJFA458A is rebuilt： changing seats of middle rollers,increasing the regulating range of top support plate,using passive bottom cleaner and so on.The spinning scheme to spin different length fibers is provided.Through spinning the modified polyester fibre/ viscose fibre of 38-51 mm and 85 mm,the spinning effect of the new fly frame is verified.The results show that the new fly frame can spin roving with multi-length fiber and the quality of control spinning is better than slip spinning.
