摘　　要：介绍了常发性纱疵的细节、粗节和棉结3种情况,指出常发性纱疵主要产生的原因,列举案例说明原料性能和工艺流程是否合理对常发性纱疵的影响,并提出常发性纱疵控制方法。结果表明,从原料的选配、工艺、设备、纺纱关键器材等入手加以系统控制,使用好现有检测仪器,做好清洁工作,加强设备的更新改造和并粗细工序牵伸的合理配置,采用新型金属针布,增加梳棉机盖板速度等方法可有效地减少常发性纱疵的产生。Introduces the normal yarn faults in detail, slub and nep of 3 kinds of situation,pointed out thatthe reason for normal yarn mainly produced, A case study is given to illustrate the influence of raw material per-formance and process flow on the normal yarn faults, and a method for controlling the normal yarn faults is pforward. This paper shows that, from the selection of raw materials, technology and equipment, key equipment ofspinning control system, the use of existing testing instruments, do cleaning work, strengthen equipment renewal and renovation and reasonable arrangement of drawing in thick and thin process, the adoption of new metal needle cloth to increase the speed of carding machine cover plate can effectively reduce the occurrence of normal yarn faults.
