摘要
为了减少突发性长细节纱疵,详细分析了并粗工序与细纱工序产生突发性长细节纱疵的6个案例,即集束器吸条子造成的不规律长细纱疵、严重机械波造成的Cm/CCm纱疵异常、粗纱后胶辊运行不良造成意外牵伸、粗纱后罗拉轴头键槽与键磨损造成规律性细节、粗纱高架上频繁劈条子以及粗纱停喂装置碰后胶辊造成细条等,探讨问题产生的原因并提出解决措施。结果表明:长细节纱疵是纺纱各项基础性工作的综合反映,应根据不同纱疵问题产生的具体原因,针对性制定科学操作方法,及时整改设备问题,使长细节纱疵消失;解决长细节纱疵是系统性工作,日常应多开展捉疵、防疵活动,发现异常及时处理。
In order to reduce the sudden long thin places defects,six cases of sudden long thin places defects in drawing,roving and spinning process are analyzed in detail.The cases include the irregular long thin places defects caused by condenser suctioning the sliver,the abnormal Cm/CCm yarn defects caused by severe mechanical waves,the unexpected drafting caused by poor operation of back cots in roving,the regular thin places caused by wear of the keyway and key of the back roller head in roving,the frequent splitting of slivers on the roving overhead and the thin slivers caused by the roving stop feeding device colliding with the back cots,etc.The causes of the problems are explored and solutions are proposed.The results show that the long thin places defects are comprehensive reflection of various basic spinning tasks.According to the specific causes of different yarn defects,scientific operation methods should be formulated,and equipment problems should be corrected in time to make long thin places defects disappear.Resolving long thin places defects is a systematic work,so we should carry out more activities to catch and prevent defects,and deal with abnormalities in time in daily life.
