<section data-role="outer" class="article135" label="edit by 135editor"><p style="vertical-align: inherit; margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: 25.6px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &quot;Helvetica Neue&quot;, Helvetica, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei&quot;, Arial, sans-serif; overflow-wrap: break-word !important;">纺织商务谈判及合同签订中往往对坯布有克重要求,坯布克重是指坯布每平方米的无浆干燥重量,简称坯布无浆干重。它是坯布的一项重要的技术指标,也是对织物进行经济核算的主要指标。</p><p style="vertical-align: inherit; margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: 25.6px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &quot;Helvetica Neue&quot;, Helvetica, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei&quot;, Arial, sans-serif; overflow-wrap: break-word !important;"><br></p><p style="vertical-align: inherit; margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit;

overflow-wrap: break-word !important;">  根据坯布样的大小及具体情况,可分为两种试验方法:称重法和计算法。计算法需要知道经纬纱织造缩率,有时估算经纬纱缩率偏差较大,导致计算结果误差较大,一般情况下企业的实验室和检测中心都采用较准的称重法来测试坯布无浆干重。</p><p style="vertical-align: inherit; margin-bottom: 0px;

font-family: &quot;Helvetica Neue&quot;, Helvetica, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei&quot;, Arial, sans-serif; overflow-wrap: break-word !important;"><br></p><p style="vertical-align: inherit; margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: 25.6px; max-width: 100%; clear: both; min-height: 1em;

margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: 25.6px; max-width: 100%; clear: both; min-height: 1em;

margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: 25.6px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &quot;Helvetica Neue&quot;, Helvetica, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei&quot;, Arial, sans-serif; overflow-wrap: break-word !important;"><br></p><p style="vertical-align: inherit; margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: 25.6px; max-width: 100%; clear: both; min-height: 1em;

margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: 25.6px; max-width: 100%; clear: both; min-height: 1em;

margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: 25.6px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &quot;Helvetica Neue&quot;, Helvetica, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei&quot;, Arial, sans-serif; overflow-wrap: break-word !important;"><br></p><p style="vertical-align: inherit; margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: 25.6px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &quot;Helvetica Neue&quot;, Helvetica, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei&quot;, Arial, sans-serif; overflow-wrap: break-word !important;">  1、取样布:用圆盘取样器取试验用的坯布样(面积为100平方厘米)或用剪刀把样布剪成长方形或正方形,用直尺量样布的长和宽,计算样布的面积(平方厘米)</p><p style="vertical-align: inherit; margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: 25.6px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &quot;Helvetica Neue&quot;, Helvetica, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei&quot;, Arial, sans-serif; overflow-wrap: break-word !important;"><br></p><p style="vertical-align: inherit; margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: 25.6px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &quot;Helvetica Neue&quot;, Helvetica, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei&quot;, Arial, sans-serif; overflow-wrap: break-word !important;">&nbsp; &nbsp; &nbsp; &nbsp; 2、(按10克坯布对应最少700ml水的比例)量杯量取试验样布所需的水加入铜锅(或烧杯)中,然后放在电磁炉上加热,待水沸腾后放入样布煮10分钟,用玻璃帮把样布捞出,用清水洗一下。</p><p style="vertical-align: inherit; margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: 25.6px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &quot;Helvetica Neue&quot;, Helvetica, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei&quot;, Arial, sans-serif; overflow-wrap: break-word !important;"><br></p><p style="vertical-align: inherit; margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: 25.6px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &quot;Helvetica Neue&quot;, Helvetica, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei&quot;, Arial, sans-serif; overflow-wrap: break-word !important;">   3、(按10克坯布对应最少700ml水的比例)再用量杯量取试验样布所需的水加入铜锅(或烧杯)中,放在电磁炉上加热至沸腾,(按700ml水对应14ml稀硫酸的比例)用量杯量取适量稀硫酸加入,把样布也放入沸腾的水中,盖上盖子,煮40分钟,用碘液检测样布退浆是否干净,若没退净,继续煮,直到浆退干净为止,用玻璃棒捞出样布用清水冲洗干净。</p><p style="vertical-align: inherit; margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: 25.6px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &quot;Helvetica Neue&quot;, Helvetica, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei&quot;, Arial, sans-serif; overflow-wrap: break-word !important;"><br></p><p style="vertical-align: inherit; margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: 25.6px; max-width: 100%; clear: both; min-height: 1em;

margin-bottom: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: 25.6px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &quot;Helvetica Neue&quot;, Helvetica, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei&quot;, Arial, sans-serif; overflow-wrap: break-word !important;"><span style="margin: 0px;
