<section data-role="paragraph" class="_135editor" style="font-size: medium; max-inline-size: 100%; margin: 0px; padding: 0px; border: 0px none; z-index: 0; overflow-wrap: break-word !important; outline: none 0px !important;"><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;"><span style="max-inline-size: 100%; margin: 0px; padding: 0px; cursor: text; font-size: 14px; overflow-wrap: break-word !important; outline: none 0px !important;">  通常把涤纶锦纶这类化纤叫热塑性纤维,是因为在热作用下,这类纤维大分子运动加剧,分子链发生重排,晶区发生溶融和重结晶,内应力消除,大分子在新的位置建立稳定相互作用和联结,即在热作用下发生了超分子结构层面的重塑。</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; 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;"><span style="max-inline-size: 100%; margin: 0px; padding: 0px; cursor: text; font-size: 14px; overflow-wrap: break-word !important; outline: none 0px !important;">  而棉麻这类纤维素纤维不具备热塑性,它们要发生上述类似的超分子结构层面的重塑,要在其“溶胀-溶解”态下,比如液碱或液氨丝光条件下,纤维素大分子链发生重排,半晶区发生溶解,转变为无定形区,内应力消除,大分子在新的位置建立稳定相互作用和联结,如果这时外界施加张力其取向度也会随之增加,即在“溶胀-溶解”作用下发生了超分子结构层面的重塑。</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; 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;"><span style="max-inline-size: 100%; margin: 0px; padding: 0px; cursor: text; font-size: 14px; overflow-wrap: break-word !important; outline: none 0px !important;">  因此棉麻可以称为溶塑性纤维,这是我刚发明的一个新词。</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; 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;"><span style="max-inline-size: 100%; margin: 0px; padding: 0px; cursor: text; font-size: 14px; overflow-wrap: break-word !important; outline: none 0px !important;">  丝光这个词有一定的误导性,导致不少人望文生义的去理解丝光在染整中作用,认为仅仅是增加织物光泽,这是有问题的。丝光英文为Mercerizing,其含义是非常中性,这项处理技术最先由Mercer发明,才被命名为Mercerizing。中文译成丝光后,其实对于麦赛处理的内在含义,是有误导性的,“丝光”对棉麻等纤维素纤维织物性能改善有很多,而且每项都可以追溯到其超分子结构层面的原因:</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; font-size: 14px; overflow-wrap: break-word !important; outline: none 0px !important;">  1,拉伸强力增加:在有张力的情况下发生超分子结构重排,取向度增加所致。取向度对纤维强度的影响如下图</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; font-size: 14px; overflow-wrap: break-word !important; outline: none 0px !important;">  2,染深性增加:半晶区被溶解,转变成无定形区,无定形区占比增大。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; font-size: 14px; overflow-wrap: break-word !important; outline: none 0px !important;">  3,反应活性增加:原先在水中不可及的羟基,经丝光后变得可及,与染料、纤维素酶等药剂的反应活性提高。</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; font-size: 14px; overflow-wrap: break-word !important; outline: none 0px !important;">  4,尺寸稳定性增加:内应力消除,大分子在新的位置建立稳定相互作用和联结,全棉梭织布纬向门幅控制,丝光落布门幅是关键控制点。</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; font-size: 14px; overflow-wrap: break-word !important; outline: none 0px !important;">  5,消除布面褶皱:在有张力下将褶皱拉平,通过强碱的溶胀-溶解作用重塑纤维超分子结构,令纤维素大分子在平整状态下再次建立稳定的相互作用和联结,而达到去除褶皱的目的。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; font-size: 14px; overflow-wrap: break-word !important; outline: none 0px !important;">  7,织物手感挺阔增加:强碱大溶胀导致有捻纱线发生内塌缩,纱线变得更紧实,导致织物挺括度增加</span></p><p style="max-inline-size: 100%;

padding: 0px; cursor: text; font-size: 14px; overflow-wrap: break-word !important; outline: none 0px !important;">  8,织物活络度变好,悬垂性增加:强碱大溶胀导致有捻纱线发生内塌缩,纱线变得更紧实更细,使得织物间留有缝隙,这些缝隙成为纱线的自由活动空间,使织物变得更活络,悬垂感更好。而且这些纱线弯曲的内应力处于消除状态,而不是紧绷状态,也会令活络感有所提升。</span></p><p style="max-inline-size: 100%;

padding: 0px; cursor: text; font-size: 14px; overflow-wrap: break-word !important; outline: none 0px !important;">  9,抗起毛起球性能改善:大溶胀导致有捻纱线发生内塌缩,纱线变得更紧实,纱体对纤维的抱合力增加,起毛起球改善。</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; font-size: 14px; overflow-wrap: break-word !important; outline: none 0px !important;">  10,改善入(吸)水后的柔软度:纤维素纤维织物入水变硬是由于其纤维入水以后横向产生大溶胀,导致纱线变粗,织物紧度变大而变硬。丝光的强碱大溶胀导致有捻纱线发生内塌缩,纱线变得更紧实更细,使得织物间留有弯曲缝隙。因水溶胀远小于碱溶胀,这种强碱极致溶胀涨开的缝隙,在遇水溶胀时会留有余地,从而使得湿织物的紧度并不会变得特别大,而改善了织物入水手感变硬的情况。同时入水紧度的控制变小亦会改善织物的水中抗皱性能。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; font-size: 14px; overflow-wrap: break-word !important; outline: none 0px !important;">  11,布面变得更平整:通过消除内应力的方式消除纺丝残留扭矩,使纱线在布面上更帖服,不发生布面扭结扭转拱起。12,消除配棉差的棉布面死棉疵点。</span></p><p style="max-inline-size: 100%;
