padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　条干均匀度是指纱条在长度方向横截面的粗细均匀度。纱条条干的均匀度对以后的布面条干均匀度起着决定作用，而布面条干均匀度是纺织品评等级的主要依据。成纱条干均匀、布面平整、纹路清晰、条影少、手感舒适，那么用它加工出的纺织品质量也高，针织物对条干均匀度的要求比机织物高。尤其是细节、竹节纱疵会造成断头和纺织品明显的疵点。如果想要良好的织物外观，纱线条干的均匀度要好。原棉中的以下几个因素对纱线条干均匀度产生的主要影响有：</span></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important;

margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　短纤维含量和长度整齐度。由于纤维长度是决定纺纱工艺和设备的主要依据。罗拉隔距、加压、牵伸倍数、捻度等纺纱工艺参数都对成纱条干有显著的影响，而短纤维含量与长度整齐度关系密切，一般短纤维含量高的，整齐度也差，所以长度整齐度和短纤维含量对纱线条干的均匀度有较大影响。纺纱过程中牵伸机构不能对不同长度的纤维进行有效控制，导致部分纤维的失控和浮游时间长，是构成浮游纤维的主要部分。浮游纤维越多，牵伸形成的不均匀度就越严重。如果纺织厂使用不同产地的棉花，长度差异很大时，除了考虑短纤维含量外，还须注意纤维的长度，减少各地棉花间的长度差异，因为混合棉中长度整齐度差，罗拉隔距等工艺参数就需要重新调整。</span></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important;

margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　回潮率。原棉回潮率对纺织厂的纺纱也有很大的影响。大家都知道，棉纤维吸水后，横向膨胀，强力增加，弹性变差，柔软性增加，相互间摩擦增加，产生静电的能力和电阻均降低；反之，棉纤维失水后，横向收缩，强力下降，弹性变好，相互间摩擦减少，产生静电的能力和电阻均增高。原棉回潮率高，棉块不易开松，棉卷易层层粘结，棉卷不均增高，梳棉机分梳除杂效率低，棉网易下垂，生条均匀度差。棉条回潮率高，棉纤维柔软度增加，有利于罗拉对纤维的控制，牵伸过程纤维易伸直平行，并可增加纤维间的抱合力，减少飞花，改善条干均匀度。但是，棉条回潮率太高的话，又容易在皮辊、罗拉、皮圈等部位发生缠绕现象。原棉回潮率太低，纺织过程中纤维容易被打断和损伤，短纤维增多，静电增高，在皮辊、罗拉、皮圈等部位产生“干绕”现象。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　细度。研究表明，纤维越细，而且整体的细度差异小，对改善条干的均匀度就越好，但细度常常受成熟度控制，细度太细成熟度一般都较差，强度和品级偏低，清梳处理中纤维容易断裂，形成短绒，还形成棉结，间接影响成纱条干的均匀度。</span></p><p style="max-inline-size: 100%;

padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　在实际工作中发现：棉结、索丝、不带破籽壳的僵片对纺纱无任何益处，纺织厂早已将棉结、索丝和不带破籽壳的僵片列入杂质中。鉴于棉结、索丝、不带破籽壳的僵片对纺织品的危害与杂质相同，没有本质的区别，为了统一标准，进一步提高我国棉花检验方法标准的国际竞争力和在实际工作中的指导意义，促进我国原棉质量的提高，便于纺织工业使用，建议将索丝、棉结和不带破籽壳的僵片列入杂质的定义中，检验方法应与疵点检验方法一致，均应在10g试验样中进行检验，这样就能更好地指导纺织厂正确计算用棉量，降低成本，并减少成品疵点，提高产品质量。</span></p><p style="max-inline-size: 100%;
