摘要:为了减少纱线毛羽、提高成纱质量,详述环锭纺和集聚纺纱线毛羽形成机理,以及毛羽指数H值和根数毛羽的检测方法及原理,分析纤维线密度、长度和刚度等指标对纱线毛羽的影响。以针织纱为例,对比不同粗纱定量、隔距块规格和钢丝圈型号对纱线毛羽指数H值以及其他成纱质量指标的影响。指出:不同原理和技术方法的测试仪测试毛羽结果差异较大,评价应选用同型号仪器;粗纱定量对加捻三角区宽度影响大,纤维长度是影响纱线毛羽的根本因素,钢丝圈是影响细纱工序毛羽增加的关键因素;生产中,应重点关注粗纱号数选择、熟条以及粗纱中的纤维长度,通过试验对比确定钢丝圈号数和弓形。

Abstract:In order to reduce yarn hairiness and improve yarn quality,the formation mechanism of yarn hairiness in ring spinning and commpact spinning is described,and the detection method and principle of hairiness index H value and number hairiness are described in detail,and the effects of fiber linear density,length and stiffness on yarn hairiness are analyzed.Taking knitting yarn as an example,the influences of different roving weight per unit,spacer specifications and traveler types on yarn hairiness index H value and other yarn quality indexes are compared.It is pointed out that there is a great difference in the test results of hairiness by the tester of different principles and technical methods,and the same instrument should be used for evaluation.The roving weight per unit has great influence on the width of twist triangle area,the fiber length is the fundamental factor affecting yarn hairiness,and the traveler is the key factor affecting the hairiness increase in spinning process.In production,we should pay more attention to the selection of roving number,and fiber length in drawn sliver and roving,and determine the number and bow of traveler through test and comparison.
Key Words:hairiness;ring spinning;commpact spinning;twisting triangle area;hairiness index;number hairiness;roving quantity;spacer;traveler
