Embodiment 1

[0030] With the dyestuff A of 60 grams of formula (Ia), the dyestuff B of 16 grams of formula (IIb), the dyestuff C of 24 grams of formula (IIIa), the sodium lignosulfonate of 195 grams, after adding water and blending, grind and disperse with grinder , and spray-dry to obtain the finished product. The dye can provide bright blue color to the fabric.

[0031]

Embodiment 15

[0039] Take 0.5 grams of the disperse dyes prepared in Examples 1 to 14 and disperse them in 500 milliliters of water, absorb 20 milliliters and mix them with 60 milliliters of water, adjust the pH of the dyeing bath to 5 with acetic acid, heat up to 70°C and put 2 grams of poly The ester fiber is dyed, the temperature is raised from 70°C to 130°C within 30 minutes, the temperature is kept for 30 minutes, and the sampling starts when it is cooled to 90°C. Observe the color and light of the sample cloth, and use the national standard GB / T3921-1997, GB / T3920-1997, GB / T3922-1997, GB / T8427-1998 to test its fastness to washing, rubbing, perspiration and sunlight respectively. The results are shown in table 3.

Abstract

A dispersed blue dyestuff compound is made up of the one or a few dyestuff A, one or few dyestuff B, one or a few dyestuff C and the assistant which the weight percent of the A is 30-90%, the B is 5-50%, the C is 1-40%. The Dacron fiber material dying by the dyestuff has the good pile-on properties, so the dying fabric has the good color, dispersibility and sun proof, wash resistance, sweat resistance.

Description

(1) Technical field [0001] The invention relates to a disperse blue dye composition, in particular to a disperse blue dye composition for printing and dyeing polyester materials. (2) Background technology [0002] C.I. Disperse Blue 56 is recognized as one of the most important blue disperse dyes in the world. It can provide polyester and polyester blended fabrics with extremely bright red light blue and excellent light fastness. However, the anthraquinone dyes represented by this have unsatisfactory coloring strength, which increases the dyeing cost and pollution when dyeing dark colors. In addition, there are also deficiencies in level dyeing. With the rapid development of new polyester fibers in recent years, higher requirements have been put forward for the dyeing performance of disperse dyes. Therefore, in order to overcome the deficiency of C.I. Disperse Blue 56, people try to add other disperse blue dyes for blending, so as to improve the dyeing properties such as l...
