overflow-wrap: break-word !important;">用手感知针布锐度，将其分为5个等级：针齿锋利，有粘手、刺痛之感为上等针布；针齿锋利，颇有刺手感为中上等针布；针齿锐利，有刺手感为中等针布；针布稍具锐度，有正反方向感为中下等针布；针布滑溜，无正反方向感为下等针布。评价针布的锐度，以整个的锡林、道夫、盖板和刺辊幅宽内为准。</span></p><p style="text-align: justify;

overflow-wrap: break-word !important;">通过感官判断针布质量是最直接的方法，能够快速地对针布状态做到心中有数。在生产中，梳棉机上针布锐度、表面粗糙度通过感官判断已经到中下等，但由于整个机台上针布齿尖的圆柱度相当好，使隔距的校正相当标准，并且保证了上机生产中左、中、右隔距的一致性，达到了工艺要求，且指标较稳定。虽然有的梳棉机因为针布的锐度和表面粗糙度指标不稳定更换了针布，更换后产品指标反而下降，并给梳棉保全带来难度，不但浪费人力、物力，还降低了保全工的工作积极性，丧失工作信心。笔者认为，通过感官判断针布的锐度、表面粗糙度，从而界定针布是否失效，并不能满足生产管理的需求。</span></p><p style="text-align: justify;
