overflow-wrap: break-word !important;">在纺纱从清花→梳棉→精梳→并粗→细纱的工艺流程中，有优良的半制品是纺好纱基础，所以要找出原因就要注意源头可能产生的问题。如：棉包堆放排列不当，开松、抓取不良;棉卷不匀、轻重卷，不把关上棉台;缠罗拉、胶辊、生条轻重不匀、轻重条，不取出精梳棉网破洞或重叠粘卷;并、粗牵伸后形成长粗节、长细节。偶发性的长粗节、长细节主要产生于前纺的并粗工序，重点是设备和操作原因造成，工艺不当也会产生此类疵点。针对以上问题，需提高值车工的质量意识，把一切因掉(棉网、棉条)、缠、粘、挂产生的不良条子及时取出，预防流入下工序形成纱疵。</span></p><p style="margin-bottom: 0px;
