Problems solved by technology

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

Abstract

The invention discloses an application of a blue disperse dye composition as blue disperse dye. The composition 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 the application of 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.
