margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="text-align: center; margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; line-height: 1.75em; overflow-wrap: break-word !important;">　　01、认识莱卡纤维<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　“莱卡”是英文单词LYCRA的译音。作为一种氨纶弹力纤维，由柔性链段和刚性链段组成的嵌段分子链段聚氨基甲酯。它是1937年由德国拜尔公司(Bayer)研究成功，1959年美国杜邦公司(DuPont)开始生产，是杜邦公司氨纶纤维的注册商标。由于具有诸多优点和良好的品质被同行所认可，因此只要采用了莱卡的服装都会挂有一个三角形吊牌，这个吊牌也成为高质量的象征。<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="text-align: center; margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; line-height: 1.75em; overflow-wrap: break-word !important;"><img src="https://dayaotex-edu.fsh.bcebos.com/v1/dayaotex-edu/20210916111411.png?authorization=bce-auth-v1%2F59b7a26546d74b64bfd056b483465817%2F2021-09-16T03%3A18%3A26Z%2F-1%2F%2F85d0be9358527bbc0c1907a2a8fc5a36175f5a2ff2b1f545d434b1cd6c10aa1e" style="width: 726px;" data-filename=""> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　虽然莱卡纤维是一种合成弹力纤维，在美国也被称为氨纶，且氨纶与弹性纤维是同一种物质的通用名，但是只有莱卡公司生产真正的LYCRA（莱卡）纤维。<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　那么，氨纶与莱卡有什么区别呢？<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="text-align: center; margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; line-height: 1.75em; overflow-wrap: break-word !important;">　　02、氨纶与莱卡的区别<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　1）莱卡属于氨纶的一种，但氨纶不一定是莱卡<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　莱卡比一般氨纶性能更好，拥有特殊的化学结构，在湿水后处于湿热密封的空间里也不会长霉。<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　2）氨纶是一种高分子化合物弹性纤维<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　氨纶，又名聚氨酯类纤维，具有其他纤维无法比拟的优点，如：比重轻、断裂强度高、断裂伸长高、弹性回复好等。<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　3）莱卡的伸展度可达500%，且能回复原样<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　莱卡的伸展度远远优于传统弹性纤维，它可以非常轻松地被拉伸，回复后仍可紧贴在人体皮肤表面，对人体的束缚力很小。<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="text-align: center; margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; line-height: 1.75em; overflow-wrap: break-word !important;">　　03、莱卡纤维的特点<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　1）纤维细度范围广<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　莱卡纤维细度范围为22~4778 dtex，最细的橡胶丝为156 dtex。由于莱卡比其他弹性纤维在织造过程中张力更均匀，所以含莱卡的织物具有良好的平整度，且手感柔软。<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　2）更高的强度及伸长性<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　莱卡的强度是橡胶丝的2~4倍。由于莱卡在同样伸长下比橡胶丝有更大的弹性，所以含莱卡的织物有更高的松紧度。<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　3）耐高温性<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　弹力织物一般都是由少量的弹性纤维与其他纤维混合而成。常规合成纤维的热定型、染色都必须经过高温热处理，故混纺用弹性纤维也必须经得起高温热处理。莱卡丝热定型温度可达195℃，而其他品牌的弹性纤维最高热定型温度为180~185℃。所以，在同样高温条件下，含莱卡织物的拉伸率及回弹力比其他弹性织物更显优势。<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　4）水洗缩率及增长率低<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　织物的水洗缩率及增长率是影响成衣尺寸稳定性和抗皱性的主要因素，也是反映织物和成衣变形的重要指标。水洗缩率及增长率低，说明服装保形性好，织物不易变形起皱。<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　5）拉伸性和回弹性好<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　适当的回复和保持度给予弹性织物舒适的伸缩性、形态保持性、适身性、成形性。莱卡可以伸展到比原来长7倍的长度而不断裂；回缩性也很好，伸长50%时，回缩率大于99%；伸长200%时，回缩率为97%；即使伸长500%时，其回缩率也在90%以上。其回缩率的大小与纱线粗细有关，纱线越粗，回弹力越大。<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　6）可染色<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　莱卡可用酸性、金属络合、活性和分散等染料染色，而橡胶丝不易染色。<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　7）抗老化性和不易泛黄<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　含氨纶丝的织物或加工的服装，随着时间的延续，反复使用或洗涤会产生泛黄，而含莱卡的弹性毛坯放置三个月，其白度比其他氨纶织物要好得多，白度保持比一般产品好10%~20%，同时有较好的抗老化性。<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　8）耐磨性好<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　在伸长范围为50%~300%，每分钟做200次疲劳试验，可耐100万次以上而不断裂，而橡胶只有24万次。<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　9）耐光性和耐氯性好<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　莱卡在耐晒牢度试验仪中照40 h，强力降低约20%。而橡胶丝经同样照射，导致老化，使强力全部丧失。<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;">　　莱卡对一般化学药品有一定的抵抗力，但对氯（如NaClO漂白剂）相对比较敏感，使纤维泛黄损伤，使之失去弹性和延伸性，这是它最主要的缺点之一。对含氧的漂白剂比较稳定。<p style="margin-right: 8px; margin-bottom: 0px; margin-left: 8px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-align: justify; line-height: 1.75em; overflow-wrap: break-word !important;"> <p style="text-align: center;
