活性染料单面防印工艺

Blotch reverse printing with reactive dyestuffs

对于比较复杂的花型,采用活性染料直接印花,存在着对花困难,印花易产生疵病等问题,而采用防印印花工艺可获得较好的效果。介绍了K型活性染料防印KN型活性染料、涂料酸性防印活性染料和涂料胶浆防印活性染料等三种防印工艺的染料选择、色浆配方和操作注意事项等。

Problems such as poor register and printing defects easily arise in direct printing with reactive dyes for complex patterns. Reserves printing can produce good results in these conditions. This paper introduces three processes such as K reactive dyes reverse printing KN reactive dyes, pigment plusing citric acid reverse printing reactive dyes, and pigment mucilage reverse printing reactive dyes. Matters needing attentions are put forward.
