Embodiment 1

[0050] After uniformly mixing 28 grams of dye 1, 31 grams of dye 2 and 41 grams of sodium lignosulfonate, a powdery dye composition is obtained. Use it to dye polyester fabrics, the color is bright, and the tone is similar to C.1. Disperse Blue 56.

Embodiment 2

[0052] 10 grams of synthetic raw dye of structure (I-1), 26 grams of dye 2, 2 grams of dye 4, 5 grams of diffusing agent MF, 1 gram of urea, 2 grams of glycerin and 54 grams of water were mixed, and then made into The micronized dye suspension is filtered to obtain a liquid dye composition, which is used to dye polyester fibers with bright colors and similar hues to C.1. Disperse Blue 56.

Embodiment 3～6

[0054] According to the data shown in Table 1, the corresponding dye composition can be obtained after mixing the dye components and the diffusing agent uniformly. It is used to dye polyester fabrics in bright blue.

Abstract

The invention relates to a composition of cobaly blue dispersed dye, belonging to the technical field of dyeing and printing of textile containing polyester fiber. The composition of cobaly blue dispersed dye utilizes anthraquinone dye and azo dye to complement mutual advantages, the obtained composition of the cobaly blue dispersed dye has good fastness and dyeing performance, increases dyeing capability of the dye, particularly improves sublimation fastness of the dye, overcomes the defects in C.1. dispersed blue 56, simultaneously improves wash fastness, and has wide application prospect.

Description

technical field [0001] The invention relates to a bright blue disperse dye composition, which belongs to the technical field of dyeing and printing of polyester fiber textiles. Background technique [0002] Among the disperse dyes, C.1. Disperse blue 56 is recognized as a bright and firm disperse blue, and is widely used at home and abroad. However, the sublimation fastness of the dye is low, and discoloration and staining will occur during heat-melt dyeing or heat finishing of the dyed fabric, which will reduce the quality of the dyed fabric, so the scope of its use is limited. For this reason, provide a kind of disperse blue with bright blue color and strong color, improve its sublimation fastness, make it suitable for the medium-temperature hot-melt dyeing process and printing of energy-saving continuous dyeing at the same time, to overcome the shortcomings of C.1. Disperse blue 56 especially necessary. Contents of the invention [0003] In order to overcome the probl...
