azo dyeing

Azoic dyeing consists of reacting two components, neither of which itself is a dye, with one another inside the fiber to form an azo pigment.

不溶性偶氮娶嵯染色有两个反应组分组成，其中任何一个单独存在都不能称之为燃料，他们彼此在纤维中形成不溶性偶氮颜料。

Azo dyes are widely used by printing and dyeing industries, because of their bright colour, high fixation rate and good color fastness.

偶氮染料因其本身鲜艳的色泽，较高的固色率，良好的染色牢度等优势而被印染行业所广泛认同。

The dyeing properties of new non-azo dye ( Leather Black LR-N) for leather were studied by Color Difference analysis and UV-Vis spectroscopy.

本文利用色度色差分析及紫外可见吸收光谱等研究了非偶氮皮革专用新型染料一皮革黑LR-N的染色性能。
