摘　　要：为了防控偶发性疵点,降低疵品率,分析异性纤维、横条、竹节疵点、飞花毛羽、大棉粒、乱纱、腰带纱等常见偶发性疵点的危害、成因和防控措施。指出:异性纤维的防控应保证棉花纯度、提高异纤检出率;规律性横条的防控要确保纱线品质,注意调整针织机工艺参数;规律性竹节疵点的防控应加强生产检查,杜绝粘缠堵挂问题,并按周期扫锭;非规律性竹节疵点的防控应合理优化牵伸工艺,确保同台同品种的纺纱工艺和器材专件一致,控制浮游纤维;飞花毛羽的防控应结合空调调节及优化工艺,加强清洁清扫和过程检查;大棉粒的防控应优化主要梳理器材隔距;自动络筒机异纤清除功能在异性纤维、竹节疵点、飞花毛羽、乱纱、腰带纱的防控方面发挥重要作用;挡车工应加强把关意识,做到勤检查、善分析总结并落实,以减少客户对偶发性纱疵的投诉。In order to prevent and control the occasional yarn defects and reduce the defect rate,the hazards,causes and prevention measures of the common occasional defects,such as foreign fiber,stripiness,slub defects,flying hairines,big neps,ravelings,belt yarn are analyzed.It is pointed out that we should ensure the purity of cotton and improve the detection rate of foreign fiber to prevent and control foreign fiber;we should ensure the yarn quality and pay attention to adjust the process parameters of knitting machine to prevent and control regular stripiness.To prevent and control regular slub defects,production inspection should be strengthened to prevent sticking,winding,plugging and blocking,and spindle cleaning should be carried out periodically.To prevent and control irregular slub defects,the drafting process should be rationally optimized to ensure that the spinning process and accessories of the same machine and variety are consistent,and control the floating fiber.The prevention and control of flying hairines should be combined with air conditioning and process optimization,and strengthen cleaning and process inspection.The gauge of main carding accessories should be optimized to prevent and control big neps.The clearing function of foreign fiber of automatic winder plays an important role in the prevention and control of foreign fiber,slub defects,flying hairines,ravelings and belt yarn.In order to reduce customers’complaints of occasional yarn defects,textile worker should strengthen the awareness of inspection,and make regular inspection,good analysis,su-mmary and implementation.
