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: 15px; overflow-wrap: break-word !important; outline: none 0px !important;">　　①涂料粒子的细度及用量是影响摩擦和刷洗牢度的重要因素，涂料颗粒细度要求在0．2～1μm之间，2μm以下粒径的涂料尚可使用，大于2μm的牢度明显下降。如涂料蓝FFG是酞菁结构，颗粒较大，用量多时，往往牢度不合格。</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: 15px; overflow-wrap: break-word !important; outline: none 0px !important;">　　②黏合剂的选用也很重要，涤棉混纺织物印花时应考虑黏合剂的成膜牢度及耐热性和热变性。成膜牢度包括膜本身的牢度和膜在织物上的缚合力。缚合力不良会造成熨烫时膜的脱落，促使花纹剥皮。故黏合剂及交联剂的用量要比纯棉织物上高。一般不小于40%～50％，交联剂不少于3％，并尽量选用热变性好的黏合剂。常用的有东风牌黏合剂、320胶着剂BAN及104胶着剂，高温焙烘不泛黄。为改善手感或提高牢度，也可选用}昆合黏合剂。如在东风黏合剂或104胶着剂T／C与黏合剂BH、707、750胶着剂BF中任选一种，以1：1混合使用，效果较好。</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: 15px; overflow-wrap: break-word !important; outline: none 0px !important;">　　③选择良好的乳化剂以制取乳化糊，使乳化糊的液滴分布均匀，液滴变小，可提高牢度。如用3％平平加0与5％乳化剂(聚氯乙烯非离子乳化剂)制成的乳化糊，最大颗粒直径仅1μm，而单独用5％平平加0制成的乳化糊，最大颗粒直径为3μm，后者的刷洗牢度为3-4级，湿摩2-3级，前者刷洗牢度为4级，湿摩为3-4级。</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: 15px; overflow-wrap: break-word !important; outline: none 0px !important;">　　④黏合剂与乳化糊不宜存放过久。</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: 15px; overflow-wrap: break-word !important; outline: none 0px !important;">　　⑤印花后用树脂整理可提高牢度。如用50％变性三聚氰胺甲醛10g、柔软剂EM 20g、硫酸铵3g配成1L的浸轧液，在其中浸轧、烘干，经150℃焙烘可提高刷洗牢度。也可用TMM树脂及6MD树脂进行整理，但2D树脂的整理效果较小。</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: 15px; overflow-wrap: break-word !important; outline: none 0px !important;">　　⑥印花最后宜压一只淡水白浆光板花筒，可提高织物上各种花纹的压透，以改善膜层粘搭情况和提高刷洗牢度。</span></p><p style="max-inline-size: 100%;
