overflow-wrap: break-word !important;">粗纱重量不匀率主要控制&nbsp;</span></strong></p><p style="margin-bottom: 24px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; font-variant-numeric: normal; font-variant-east-asian: normal;

padding: 0px; outline: 0px; max-width: 100%; color: rgb(89, 89, 89); visibility: visible; overflow-wrap: break-word !important;">1、由于筒管直径大小差异以及筒管孔径或底部磨灭、锭子凹槽与锭翼销子配合不良、压掌弧形或位置不当以及压掌圈数不一、锭子高低不一或因其他原因造成的锭子运转不平稳都会造成同一排粗纱伸长律的锭间差异，影响粗纱的条干。通过波普图有时还会发现有卷绕波出现。应加强机件和筒管日常性检修工作。&nbsp;</span></p><p style="margin-bottom: 24px;

color: rgb(89, 89, 89); visibility: visible; overflow-wrap: break-word !important;">2、由于卷绕齿轮选择不当而造成的同一锭子大、中、小纱之间伸长的差异，应合理配置粗纱卷绕成形齿轮，保证一落纱大、中、小纱张力的基本一致。此外粗纱的张力也随车间的温湿度变化而变化，这就要对张力齿轮的更换具有实时性。&nbsp;</span></p><p style="margin-bottom: 24px;

color: rgb(89, 89, 89); visibility: visible; overflow-wrap: break-word !important;">3、假捻器的摩擦系数会影响成纱的毛羽量，要合理选择粗纱前后排假捻器，减少前后排粗纱张力差异，前排假捻数多于后排。&nbsp;</span></p><p style="margin-bottom: 24px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; font-variant-numeric: normal; font-variant-east-asian: normal; letter-spacing: 0.544px; text-align: justify; color: rgb(62, 62, 62); font-size: 16px; line-height: 27.2px;

visibility: visible; overflow-wrap: break-word !important;">4、棉条筒的摆放。棉条筒摆放要避免规律性发生。比如供里排纱的棉条筒放在离机器近的位置，供外排纱的棉条筒放在离机器远的位置，这样就会导致供外排纱的棉条行程长，从而也会引起里外排纱重量不匀。摆放的时候也得注意尽量使棉条垂直于导棉棍平面，避免倾斜。&nbsp;</span></p><p style="margin-bottom: 24px;

overflow-wrap: break-word !important;">5、导棉棍的旋转速度也要控制好。减少棉条喂入时形成的意外牵伸。</span></p><p style="margin-bottom: 24px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; font-variant-numeric: normal;
