Problems solved by technology

[0002] In the printing and dyeing of polyester materials, Disperse Red S-5BL (that is, Disperse Red Jade SE-2GFL) is a very large dye, but the application performance of this dye is not good in dyeing reproducibility, and the level dyeing property is poor. Sensitive to the PH value of the dye bath, the dye color rate is low, and the sublimation fastness is poor
[0003] Chinese patent document CN1597790A discloses "a kind of composite disperse red dye", but has following deficiencies, the one, the compatibility of the composite disperse dye of this patent is not ideal, the 2nd, the fastness of the composite disperse dye of this patent is relatively poor

Embodiment

[0029] According to the ingredients list (Table 1) data as the basis, dye A, dye B, dye C, dye D and auxiliary agent (methylnaphthalenesulfonic acid formaldehyde condensate (MF), diffusing agent benzylnaphthalenesulfonic acid formaldehyde condensate ( CNF), diffused naphthalenesulfonic acid formaldehyde condensate (NNO), sodium lignosulfonate (Reax 85A), mixed in a certain ratio, added water in a ratio of 1:1, and then ground and dispersed in a sand mill, and then sprayed Dries into a commercial dye.

[0030] Example

[0031] Each take 0.5 grams of the disperse dyes prepared in Examples 1 to 9 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 t...

Abstract

The present invention relates to one kind of red dispersive dye mixture for printing and dyeing polyester material, and provides one new kind of red dispersive dye mixture with high level dyeing property, good dyeing reproductivity, high build-up and excellent fastness. The red dispersive dye mixture is prepared with dye A 12-27 wt%, dye B 21-42 wt%, dye C 1-10 wt%, dye D 1-10 wt%, and assistant for the rest, and through a conventional preparation process. The assistant is one or several of naphthalene sulfonic acid-formaldehyde condensate, methyl naphthalene sulfonic acid-formaldehyde condensate, benzyl naphthalene sulfonic acid-formaldehyde condensate and lignosulfonate.

Description

technical field [0001] The invention relates to an organic dye, in particular to a red disperse dye mixture for printing and dyeing polyester materials. Background technique [0002] In the printing and dyeing of polyester materials, Disperse Red S-5BL (that is, Disperse Red Jade SE-2GFL) is a very large dye, but the application performance of this dye is not good in dyeing reproducibility, and the level dyeing property is poor. It is sensitive to the pH value of the dye bath, the dye color rate is low, and the sublimation fastness is poor. [0003] Chinese patent document CN1597790A discloses "a kind of composite disperse red dye", but has following deficiencies, the one, the compatibility of the composite disperse dye of this patent is not ideal, the 2nd, the fastness of the composite disperse dye of this patent is relatively poor. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a new red disperse dye mixture ...
