background: transparent;"><p style="vertical-align:inherit;">砂洗的话和水洗的工艺其实差不多，但是加的东西不一样，一般是加碱性或者氧化性助剂，当然也会适量的加一些柔软剂。而加碱性助剂就是为了破坏面料表面的组织，使砂洗好之后的面料手感更软，然后面料的表层会起一些绒毛，还会有一层淡淡的白雾。所以，砂洗之后面料会变柔软，会起绒，面料会有一种加厚的错觉，但是这样的面料很容易发劈，轻轻一拉就有可能会破掉，我们一般不建议薄织物做砂洗。</p></section><section style="display: flex;justify-content: flex-end;margin-top: 15px;"><section style="line-height: 0;
