margin: 0px; padding: 0px; cursor: text; font-size: 15px; overflow-wrap: break-word !important; outline: none 0px !important;">　　织物的树脂整理是一种无色加工，无法用肉眼来直接判定其效果。而通常采用测定织物的撕破强力、折皱回复性、缩水率及甲醛含量等指标来评价整理效果。而树脂交联指示剂HI-2,可用点滴法或染色法来直接确定交联程度，以此来判别不同指标。使用方法如下。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; font-size: 15px; overflow-wrap: break-word !important; outline: none 0px !important;">　　①试样准备。从经树脂整理的白色织物样布上剪取5cmX 5cm试样一块，称重，用175℃ 熨斗压烫试样一半面积1min，冷却待用。</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配制HI-2染液。准确称取Hl一2若干克，加入200倍量水，搅拌均匀使之溶解，配制成Hl一20．5％的染液，取需要量的染液，加热至沸，待用。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; font-size: 15px; overflow-wrap: break-word !important; outline: none 0px !important;">　　③操作。将准备好的试样按1：60浴比投入沸染的HI一2染浴中不断翻动，沸染2min，倒去染液，用热水、冷水洗去表面浮色，然后晾干。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; font-size: 15px; overflow-wrap: break-word !important; outline: none 0px !important;">　　④交联程度的判别。树脂整理后的织物经用HI2染色后，由于交联程度不同而呈现不同颜色。一般来说，未交联试样呈绿色；部分交联试样色光偏草绿；充分交联的色光偏黄或红棕。例如几种织物用N一羟甲基类树脂整理后用HI一2染色后显示不同色相，如表5-10 所示。</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色相与物理机械性能的关系。用涤／棉布经2D树脂处理后，由于采用不同焙烘温度，用HI-2染色后得到不同色相与各项指标的关系如表5-11所示。</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;">　　使用Hi-2最适用于白色织物，如果是有色织物，则可在有色织物上缝贴一块同规格、同品种、经前处理而未染色的白布样。用Hl一2染色法鉴别树脂交联性能时，最好由工厂自己预先自制色卡，以便准确对照。</span></p><p style="max-inline-size: 100%;
