margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">　　一般有三种原因可能导致这个现象的出现，分别是原料问题、织造问题和染整问题。当染整后出现断氨纶现象时，要把布样拆散，仔细观察氨纶断裂处的形态。如果氨纶丝断点截面呈锯齿状，说明氨纶丝在染整前就受到损伤，染整过程中面料受力较大所以氨纶断裂；如果氨纶丝断点截面是球状，则是因为染色时氨纶丝熔断或者是氨纶本身质量存在问题。</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-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; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">　　纺丝方法不同，氨纶的性能差异也比较大，比如干法纺丝的氨纶弹性伸长好，回复率稍差，而湿法纺丝氨纶则相反，弹性伸长较差，但回复率比较好。所以选用不同品牌的氨纶丝，首先要先了解它的特性，然后在织造时适当调整氨纶的输纱量，以避免造成织造时产生断氨纶现象。</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; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">　　另外，氨纶生产方式不同，其结构也不同。氨纶从表面看是单根丝，其实是由几根丝复合在一起的，例如晓星牌4.4 tex（40 D）氨纶丝就是由3根单丝组成，如果在编织时断了其中的一根是不容易发现的。这就要求工人在开幅机上验布时，要经常把布用力下拉，认真检查坯布是否有小亮点，如果有，可能就是存在断氨纶现象。</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; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">　　氨纶对温度很敏感，温度过低会降低氨纶强力，尤其是北方，车间内要保持一定的温度，在氨纶使用前要提前把氨纶放在温度比较高一点的地方，把纸箱包装打开，使氨纶先预热。</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; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">　　2.织造问题</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; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">　　有的客户为了降低成本，一味地缩短氨纶的纱长，以至于氨纶丝在面料中的张力过大，染整时就容易断掉，因此，一般氨纶和纱线的纱长比例要控制在1∶3左右。</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; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">　　有时在织造时会造成氨纶损伤，这种损伤下机后肉眼是无法察觉的，但在经过染整时，氨纶丝就会断裂。例如织针表面不够光滑，从而划伤氨纶丝，或者氨纶喂纱位置不正确，导致针钩的尖部刺穿氨纶丝，损伤氨纶，特别是织造较粗的氨纶丝时尤其需要注意。</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; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">　　另外，如果设备上的机油滴到布面上，一定要及时处理干净，否则染整时氨纶丝就会发生熔断现象。</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; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">　　3.染整问题</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; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">　　氨纶汗布染色时比普通针织布多了一个坯布预定形的过程，预定形就是要先把坯布按成品布的幅宽和克质量要求在染色前先进行一次定形，这个过程对氨纶丝的损伤很大。由于氨纶丝的玻璃化温度为135 ℃左右，所以如果定形机的车速和温度控制不好，很容易产生断氨纶现象。</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; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">　　另外，如果面料进行了生物酶处理，以及面料进行返修时，染整过程中也容易出现断氨纶现象。</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; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">　　总之，造成断氨纶的原因很多，但坯布预定形是最关键的，定形的温度和车速要掌握好。此外，幅宽和克质量的掌握也要注意，假如面纱线圈长度较长、成品克质量相对比较轻，就要在织造的时候适当放长一点氨纶的输纱量，这样才不会在预定形时把氨纶拉断。另外，一旦工艺确定，就不要经常更换氨纶的品牌，这样才能使氨纶汗布的品质有保障。还有就是氨纶含量的确定不要以其他工厂为准，而是要根据自己使用的氨纶丝摸索出自己的经验，还要根据氨纶的性能在织造时相应地增加或减少一点氨纶的含量，以避免断氨纶现象发生。</p><p style="max-inline-size: 100%;
