Disperse dye mixture and its product

Abstract

The present invention relates to disperse dye mixture and its product. The disperse dye mixture and its product have excellent level dyeing property, good compatibility, high build-up and good dyeing homochromatism at different temperature. The disperse dye mixture consists of following fiver dye components: dye A 10-80 wt%, dye B 1-70 wt%, dye C 10-80 wt%, dye D 1-50 wt%, and dye E 1-35 wt%, with all the dye components being shown in the expresses. The disperse dye mixture product features its composition of the disperse dye mixture and assistant in weight ratio of 1 to 0.6-8.

Description

technical field [0001] The invention relates to a black or navy blue disperse dye mixture and its products, in particular to a black or navy blue disperse dye mixture and its products for printing and dyeing acetate fiber materials. It can be mixed with other additives, such as dustproof agent, wetting agent and so on. Background technique [0002] In order to dye acetate fiber into dark colors (such as navy blue, black, etc.) at room temperature, a dye with excellent level dyeing and lifting rate is especially needed. Generally, disperse dyes need to be dyed under high temperature and high pressure, while acetate fiber requires dyeing at room temperature, which is undoubtedly a challenge for disperse dyes. GB2346150 discloses dispersion dye mixtures and their use in dyeing or printing fibrous materials containing semi-synthetic hydrophobic cellulose acetate. If cellulose acetate is mixed, the mixture cannot color wool or cotton. In addition, some dyes suitable for acetat...
