Embodiment 1

[0039] Component A of 84 grams of formula (I-1), component A of 5 grams of formula (I-2), component B of 11 grams of formula (II-1), sodium lignosulfonate of 195 grams, add water After blending, use a grinder to grind and disperse, and spray dry to obtain the finished product. The dye can provide uniform orange color to the fabric with good fastness.

Abstract

The disperse yellow-brown dye composition and corresponding disperse dye are provided. The disperse yellow-brown dye composition consists of component A in 1-99 wt% and component B in 1-99 wt% basically, with the structures of component A and component B being shown. The disperse yellow-brown dye composition may be treated into liquid state with particle, emulsion, powder or granule. The disperse yellow-brown dye based on the disperse blue dye composition is used in dyeing polyester fiber material, and through regulating the ratio of different components, excellent yellow to orange dyed fabric with bright color, excellent dispersivity, sunfast property, water resistance, sweat resistance and other advantages may be obtained.

Description

(1) Technical field [0001] The invention relates to a disperse yellow-brown dye composition and a disperse dye, in particular to a disperse yellow-brown dye composition and a disperse dye for printing and dyeing polyester and its blended fabrics. (2) Background technology [0002] With the rapid development of new polyester fibers in recent years and the improvement of people's requirements for textiles, correspondingly, higher requirements have been put forward for the dyeing performance and environmental protection performance of the dye itself. That is to say, the dyestuffs are required to have high lifting power and various dyeing fastnesses. [0003] As far as disperse dyes are concerned, the large-scale development of new dye structures is rare, and a lot of work has turned to the research on the application performance of dyes, the synergy between dyes and the compounding and synergy of dyes and auxiliaries. However, judging from the existing varieties of compound dy...
