line-height: 24px; font-family: 宋体; overflow-wrap: break-word !important;">对于细纱牵伸不良引起的粗节、细节，可从以下四方面预防和解决：a) 降低粗纱捻度，即在不增加断头的前提下尽量采用小的粗纱捻度；b) 保证细纱和粗纱牵伸元件状态良好，保持适当的胶辊研磨周期、胶圈更换周期，并随时检查是否有起槽、划痕等问题，随时解决；c) 保持恒定的温湿度，避免出现短时大幅度的波动；d) 优化细纱工艺，主要是隔距、上销位置和摇架压力的一致性。对于细纱纺纱过程中产生的粗节和细节，只能利用络筒清纱器切除，这样会引起清纱器切次的增加，需要特别关注捻接质量避免因捻接不良二次形成粗节和细节。</span></span></p><p style="margin-bottom: 0px;
