Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a blue disperse dye composition in order to overcome the defects of existing blue disperse dye compositions such as dark shade, poor alkali resistance, and poor light fastness. Excellent, good light fastness, can be used for the one-bath scouring and dyeing method or one-bath bleaching method of strong alkali and super alkali resistance, disperse reactive same paste printing and alkaline burnt-out printing process

Abstract

A blue disperse dye composition is disclosed and comprises dye and a dispersant. A ratio of the mass of the dispersant to the mass of the dye is 0.35:1-5.0:1. The dye comprises, by weight, 15-85% of a component B and 15-85% of a component C. The component B is one or more of compounds 2. The component C is one or more of compounds 3. The composition is bright in color and light, extremely good in alkali resistance and good in light fasteness and can be used for strong-base resistant and superstrong-base resistant scouring-dyeing one bath processes or bleaching-dyeing one-bath processes, disperse / active one-emulsion printing processes and alkaline burn-out printing processes.

Description

technical field [0001] The present invention relates to blue disperse dye composition. Background technique [0002] Polyester fibers and their blended fabrics have important applications in current high-grade fabrics, and the applicable dyes are disperse dyes. When disperse dyes are used in the dyeing of polyester fiber products, acidic dyeing baths are generally used for dyeing, but acid dyeing is prone to disadvantages such as staining spots, color spots, and dyeing flowers caused by oligomer contamination. The basic dyeing process of disperse dyes can effectively remove the oligomers produced in the dyeing process, which is expected to shorten the production process, and has the characteristics of low consumption, high efficiency, energy saving and time saving. Chinese patents CN200910101329.6, CN201010240844.5, CN201110043597.4, and CN201210442433.3 all relate to disperse dye compositions suitable for basic dyeing. [0003] Blue is an important color in the applicatio...
