【摘要】 探讨消除针织物横档的纺纱质量控制途径和方法。分析了纺纱原料及纺纱过程中造成针织物起横档的主要原因,阐述了主要控制措施。指出:通过采取科学配棉,减小配棉质量波动;正确选择原料混和工艺路线,改进开清棉工艺与管理,提高原料混和质量;控制成纱捻度差异,减少成纱长粗节和长细节,降低毛羽不匀率和重量不匀率,控制好针织纱重量偏差;采用新型电子清纱器清除成纱细节等措施,可消除和减少纱线引起的布面横档。若能采用先进原料检测仪器,进一步控制配棉中不成熟纤维含量,则可取得更好的控制效果。更多还原

【Abstract】 Spinning quality control methods of eliminating knitting fabric cross bar were discussed.Spinning raw material and main reasons of causing knitting fabric cross bar were analyzed and main control measures were introduced.It is pointed out that fabric surface cross bar caused by yarn could be eliminated and reduced through adopting scientific cotton assorting,reducing cotton quality fluctuation,selecting raw material blending processing correctly,modifying opening and picking processing management,improving raw material blending quality,controlling finish yarn twist difference,reducing finish yarn long thick places and long thin places,reducing hairiness unevenness and weight unevenness,controlling knitting yarn weight variation well,adopting new electronic yarn cleaner to reduce finish yarn thin places et al.Better control effect could be made by adopting advanced raw material tester to reduce immaturity fiber content further in cotton assorting.更多还原
