padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">影响丝光效果的主要因素 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">① 棉纤维用不同浓度烧碱溶液处理后，长度和直径的变化情况： <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">浓度＞8%，直径增加，长度缩短至最大 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">②棉纱在不同浓度NaOH溶液中的收缩和染着力 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">③棉布丝光对浓度要求(C与收缩及钡值关系) <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">C=177g/L时，钡值为150，C=245g/l，钡值最高。 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">C=240~280g/l，收缩趋于稳定。 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">因此丝光最适宜的烧碱浓度是245g/l左右，考虑到织物本身吸碱、空气中酸性气体的耗碱等因素，棉布丝光碱浓度为260～280g/l。实际生产中，可根据半制品的品质和成品的质量要求选择。 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;"> <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;"><strong style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">2、张力 </strong><br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">1）、张力对织物光泽的影响 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">    棉织物用浓碱处理时，只有加上适当的张力，才能显示出良好的光泽，从张力对棉纱丝光后性能的影响可以看出：张力大，光泽好。 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">2）、张力对织物机械性能和吸附性能的影响 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">    即在无力条件下，棉纱线的强力已获得提高，如果施加适当的张力，其强力还可以进一步提高，但光泽增加的并不多，且断裂延伸度和吸附性能却有所下降。 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">3）、张力对织物缩水率的影响 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">    丝光时，经纬向张力对织物缩水率有极为重要作用。 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">    实际生产中，各种规格的织物经纬向缩水率是不平衡的。卡其、府调等经密较高的织物，经向缩水率大大超过纬向缩水率，所以优先考虑经向张力；而平布等一类薄织物则正好相反。 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;"> <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;"><strong style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">3、温度</strong> <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">烧碱与纤维素纤维的作用是放热反应，所以提高碱液温度有减弱纤维溶胀的作用，从而降低丝光效果，表现在收缩率和钡值下降，所以丝光碱液以低温较好，但实际生产中考虑到经济效益，以及温度过低碱液粘度增大，使减液难以渗透到纱线和织物内部，再有扩幅较难，所以通常采用轧槽夹层通入冷流水使碱液冷却即可。 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;"><br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;"></span></p><p style="margin-bottom: 0px;

padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">丝光作用是使烧碱迅速均匀而充分地渗入棉纱or织物内部和纤维发生作用，因此必须保证一定的时间。 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">将棉纱用280g/lNaOH在无张力下丝光，发现，20s时间就能使纱线收缩率和对染料吸收率达到最大值，延长时间对增进丝光效果并不显著。此外，时间与碱浓度和温度有关，浓度低时，应适当延长作用时间；一般采用50～60s。 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;"> <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;"><strong style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">5、去碱 </strong><br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">去碱对丝光的定型作用有很大影响，若放松张力后，织物上还有5%以上的碱，则织物仍会收缩，从而影响光泽、纬向缩水率。去碱分两步进行：①在扩幅情况下，使用冲吸装置将热稀碱淋洗织物；②放松纬向张力后，进入去碱箱，用淡碱洗蒸。 <br style="margin: 0px;

padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">与布铗丝光机的区别主要在于扩幅与初洗部分 ，其扩幅部分是由一个浅平阶梯铁槽和10～12对弯辊组成。  扩幅作用是依*织物绕经弯辊套筒弧形斜面时所产生的纬向分力将其门幅展宽。  弯辊丝光机加工时，常常两层织物叠在一起进行，产量较高，但洗碱效率低，扩幅效果差。虽有机身短、结构筒单的优点，但易产生经密不匀，纬纱成弯月状，染色易有阴阳面，应用远不如布铗丝光机广。 <br style="margin: 0px;

padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">与前两种不同的是，没有轧车和绷布辊筒，也没有扩幅装置。 <br style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">特点：常以双层进行，产量较高，丝光均匀，不会产生破边；机身较短，传动简单，操作方便，但扩幅作用差(纬回缩水率难达国标)，这是其主要缺点。国内有的厂采用布铗与直辊并用，较好的解决了这一问题。</span></p><section class="_135editor" data-role="paragraph"><p><br></p></section></section>
