Problems solved by technology

However, these three dyes have complex structures, numerous preparation procedures, long cycle times, and difficult disposal of the three wastes, which make the dyes extremely expensive. At the same time, the pH of the dyes can only be used between 3 and 8, and the compatibility is poor, and the promotion rate is low. The utilization of dyes Low rate, poor sublimation fastness

Abstract

The invention provides a disperse gray dye composition, a dye product, a preparation method and an application of the dye product, and a colored product. The disperse gray dye composition comprises, by mass, 12-25% of a component A, 19-30% of a component B, 4-15% of a component C and 40-65% of a component D. The dye product comprises the disperse gray dye composition, assistants and water. The preparation method of the dye product comprises the following steps: mixing the disperse gray dye composition, the assistants and water, and grinding the obtained mixture. The application of the dye product is characterized by dyeing and printing of synthetic fibers and blend materials thereof. The colored product is produced from the synthetic fibers or blend materials thereof, printed and dyed withthe disperse gray dye composition. The disperse gray dye composition and the dye product have the advantages of wide applicable pH range, excellent fastness, high strength, extremely low metamerism index, greenness and environmental protection.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a disperse gray dye composition, a dye product, a preparation method and application thereof, and a colored product. Background technique [0002] The original disperse gray dye, the market is dominated by N gray, and its dye composition is: disperse blue 2BLN 42%, disperse red 3B34%, disperse yellow RGFL24%, these three dyes have high light fastness, combined The disperse gray N produced has good light fastness, good level dyeing property, and can be dyed at low temperature. It is a very important disperse gray product. [0003] However, with the improvement of environmental protection requirements and people's increasing attention to safety issues, disperse yellow RGFL (C.I.23) has become a banned dye. At present, disperse yellow 3GE is mainly used to replace it in the market. The disperse gray on the market is made of disperse blue 2BLN (C.I.56), disperse red 3B (C.I.60) and disperse yell...
