&nbsp; 大家都知道，涤纶是一种化纤，表面比棉光滑且反射面较大，因此，全涤布表面光滑，有一种化纤的光泽，相对而言，全棉布就比较哑光，全涤布和全棉布是比较容易分别出来的。而现在生产的涤棉混纺布，纱线是由涤纶短纤和棉混纺而成，其中一个目的是使得这种涤棉布具有棉感外观，“以假乱真”比较难判断。如果是涤棉坯布，布面上棉子越多，颜色越黄，那么棉成分就越高。</p></section></section><section style="display: flex;justify-content: flex-end;align-items: flex-start;margin: -13px 0 0 0;"><section class="assistant" style="width: 25px;"><img class="assistant" style="vertical-align: inherit;

&nbsp; 这个是涤棉判断成分和比例主要方法，这里是两个概念，第一是判断成分，第二是判断成分比例。显然判断成分比例是比较难的。判断比例是通过两极分析法和对比分析法实现。<br>&nbsp; &nbsp; 首先，我们先看全棉布和全涤布的燃烧的表现特征分别是怎样的，那么介于中间的涤棉混纺布燃烧时各种特征肯定是全棉布和全涤布表现特征的中间有所偏向，从而判断大概比例。<br>&nbsp; &nbsp; 然后通过对比分析法，进一步判定成分比例。也就是拿一个已知比例的布一起对比燃烧，就可以更准确判断比例。我们生产销售的涤/棉65/35混纺布，经过第三方化学测试，实际比例为涤/棉65.5/34.5,&nbsp;可以作为对比参照。而市场上常规品种比例多为涤棉40/60，45/55，65/35，80/20等几种固定规格，这样判断起来就会容易一些。</p><p style="vertical-align: inherit;" hm_fix="346:478"><br><strong><span style="font-size: 16px;">那么燃烧时我们要观察那些特征呢？</span></strong></p><p style="vertical-align: inherit;" hm_fix="346:478"><span style="font-size: 16px;"><b><br></b></span>第一：<strong>烟雾</strong>，无染色的全棉布燃烧产生的烟雾是青烟或白烟，而全涤布是黑烟。而涤棉混纺布是黑烟伴有黑色飞絮，含涤越高，烟越黑，飞絮少。<br>第二：<strong>气味</strong>，全棉布是烧纸味，全涤布刺鼻烧胶味，而涤棉混纺布也是刺鼻烧胶味。<br>第三，<strong>燃烧速度和状态</strong>，全棉布易燃，且熄灭后继续伴有隐燃火星，全涤布难燃，热熔滴火，熄灭后无火星。涤棉混纺布，则介于两者之间，燃烧时出现的发亮火星越多，面积越大，熄灭后伴有火星隐燃时间越长，则含棉越多。<br>第四，<strong>燃烧残留物</strong>，无染色全棉布的是灰白色灰烬，一碰即化，全涤布则是坚硬黑色结块，且表面光滑。涤棉混纺布则介于两者之间，有黑色硬块，表面不光滑，碾压会碎但不会完全化开，含涤越多，残留物越硬，表面越光滑。</p></section></section><section style="display: flex;justify-content: flex-end;align-items: flex-start;margin: -13px 0 0 0;"><section class="assistant" style="width: 25px;"><img class="assistant" style="vertical-align: inherit;
