Embodiment 12

[0024] Each get 0.5 grams of the disperse dyes prepared in Examples 1 to 11 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 with acetic acid to be 5, 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 shade of the sample cloth, and measure its color fastness with national standards GB / T3921-1997, GB / T3920-1997, and GB / T5718-1997. The test results are shown in Table 2.

Abstract

The invention relates to a compound dispersive red dye, especially relating to a polyester material printing and dyeing compound dispersive red dye, containing the following components in weight percent: monomer A 20%-45%, monomer B 5%-15% and auxiliary. It has the advantages of high dyeing ratio, good dyeing repeatability, good dyeing uniformity, excellent fastness, approach of coloured light to dispersive red S-5BL, etc.

Description

(1) Technical field [0001] The invention relates to a composite disperse red dye, in particular to a composite disperse red dye for polyester material printing and dyeing. (2) Background technology [0002] In the dyeing of polyester materials, Disperse Red S-5BL (Disperse Red Jade SE-2GFL) is a widely used dye, but its application performance is not good in dyeing reproducibility, the color rate of the dye is low, and the pollution of three wastes in production is large. , The sublimation fastness is not good when used for printing and dyeing. (3) Contents of the invention [0003] In order to overcome the deficiencies of the existing disperse red dyes, the purpose of the present invention is to provide a composite disperse red dye that can effectively replace the existing disperse red dyes. [0004] Disperse red dye of the present invention comprises the following components by weight percentage: [0005] 20% to 45% of the monomer A shown in formula (1), [0006] ...
