Abstract

The invention relates to a complex blue dye composition, a complex dispersion blue dye and a preparation method thereof. The complex blue dye composition comprises 5-20% by weight of compound as shown in the formula (I), 35-75% by weight of compound as shown in the formula (II) and 20-45% by weight of compound as shown in the formula (III). The complex dispersion blue dye prepared by the complex blue dye composition has the advantages of good light fastness, high elevating power and high strength, and is suitable for dyeing and printing of terylene and blended fabric thereof.

Description

technical field [0001] The invention relates to an environment-friendly composite blue dye composition, a composite disperse blue dye and a preparation method thereof. The composite disperse blue dye is suitable for dyeing and printing polyester and its blended fabrics. Background technique [0002] Chinese Invention Patent No. 200810061729.4 discloses a black and blue series of environmentally friendly disperse dye compositions, but its components largely restrict the lifting power and production cost of the composition. [0003] No. 99104177.1 and No. 03107038.8 Chinese invention patents disclose a mixture of disperse azo dyes. The invention focuses on the improvement of sublimation fastness, affinity and the expansion of the applicable range of pH value, while its lifting power and light fastness effect is poor. Contents of the invention [0004] The invention provides an environment-friendly composite blue dye composition. The composite blue dye composition can not on...
