摘要: 活性黑5(活性黑KN-B)是活性染料中产量最多、用途最广的一种染料,但是最大的不足是乌黑度不高。10余年前,利用补色原理,复配了活性橙82,乌黑度有所改进,但尚有不少问题。提高活性黑5的乌黑度是当前热门的研究课题之一,主要筛选溶解度高,直接性、反应性、相容性与活性黑5匹配的橙色和红色活性染料。

Abstract: Among the reactive dyes,Reactive Black 5(Reactive Black KN-B) is the most versatile dye with the largest production volume.But its main drawback is not black enough.About ten years ago,Reactive Orange 82 was formulated using the principle of complementary color,the blackening was improved.However,some problem still remained.Improving the blackening of Reactive Black 5 is one of the hot topics under research,and the orientation is to select an orange or red reactive dye which has high solubility,and is substantive,reactive and compatible to Reactive Black 5.
