outline: none 0px !important;">　　<strong>一、定义</strong></p><p style="vertical-align: inherit; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br></p><p style="vertical-align: inherit; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 2em; overflow-wrap: break-word !important; outline: none 0px !important;">　　水洗尺寸变化的测试方法很多,目前常用方法可分为洗衣机洗涤法和浸渍法两类。洗衣机洗涤法包括家庭洗涤法和商业洗涤法;浸渍法包括冷水浸渍法、皂液浸渍法及温水浸渍法。大部分织物采用洗衣机洗涤法,而浸渍法适用于不宜剧烈洗涤的真丝织物、黏胶纤维织物及毛织物。</p><p style="vertical-align: inherit; max-inline-size: 100%;

clear: both; min-height: 1em; cursor: text; line-height: 2em; overflow-wrap: break-word !important; outline: none 0px !important;">　　<strong>二、依据</strong></p><p style="vertical-align: inherit; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br></p><p style="vertical-align: inherit; max-inline-size: 100%; margin-bottom: 0px;

margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 2em; overflow-wrap: break-word !important; outline: none 0px !important;">　　抽具体步骤：</p><p style="vertical-align: inherit; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 2em; overflow-wrap: break-word !important; outline: none 0px !important;">　　取样--调湿--测量洗前尺寸--洗涤--干燥--调湿--测量洗后尺寸--计算缩水率</p><p style="vertical-align: inherit; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 2em; overflow-wrap: break-word !important; outline: none 0px !important;">　　1、试样尺寸500㎜ ×500㎜，剪取4份试样，分两次洗涤，每次用两块。</p><p style="vertical-align: inherit; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 2em; overflow-wrap: break-word !important; outline: none 0px !important;">　　2、做标记，将试样放在平滑测量台上，在试样的长度和宽度方向，至少各做三对标，每对标记点之间相距350㎜，标记距离试样边缘应不小于50㎜。</p><p style="vertical-align: inherit; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 2em; overflow-wrap: break-word !important; outline: none 0px !important;">　　3、按要求预调湿和调湿。</p><p style="vertical-align: inherit; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 2em; overflow-wrap: break-word !important; outline: none 0px !important;">　　4、量取洗前尺寸，精确至最接近的1㎜。</p><p style="vertical-align: inherit; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 2em; overflow-wrap: break-word !important; outline: none 0px !important;">　　5、将试样放入洗衣机，加陪洗物，使其达到所选洗涤程序规定的总载荷值，加标准洗涤剂进行洗涤。</p><p style="vertical-align: inherit; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 2em; overflow-wrap: break-word !important; outline: none 0px !important;">　　5、干燥试样，并按要求进行调湿。</p><p style="vertical-align: inherit; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 2em; overflow-wrap: break-word !important; outline: none 0px !important;">　　6、测量洗后尺寸，精确至最接近的1㎜。</p><p style="vertical-align: inherit; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 2em; overflow-wrap: break-word !important; outline: none 0px !important;">　　7、结果计算，结果计算修约至0.1%</p><section class="_135editor" data-tools="135编辑器" data-id="109953"><section style="text-align: center;margin: 10px auto;"><section style="width: 100%;
