Problems solved by technology

[0002] Most of the currently used dyes have the problem of poor color fastness. During the dyeing process of vat dyes, some dyes fail to enter the interior of the fabric and can only be adsorbed on the surface to form floating colors. These floating colors seriously affect the washing fastness of fabrics. Spend

preparation example Construction

[0025] A kind of preparation technology of vat black DC dye, comprises the steps:

[0026] Step 1: Take raw materials disperse blue, disperse red, disperse green and disperse orange, diffusing agent, surfactant and dispersant;

[0027] Step 2: Raw materials are beaten and coarsely filtered, and the filtered fine materials are ground by an emulsification pump and a sand mill;

[0028] Step 3: Dry the ground slurry, and control the moisture after drying at 3% to 5%;

[0029] Step 4: testing and packaging the dried raw materials to obtain vat black DC dye.

[0030] In steps 2 to 4, the raw materials need to be filtered in each step, and the fineness of filtration should be increased successively.

Abstract

The invention discloses a vat black DC dye and a preparation process thereof, and belongs to the technical field of vat dyes. The vat black DC dye comprises, in parts by weight, 33-54 parts of disperse blue, 25-34 parts of disperse red, 20-30 parts of disperse green, 33-54 parts of disperse orange, 3-5 parts of a dispersing agent, 1-4 parts of a surfactant and 3-5 parts of a dispersing agent. Thefineness of the dye is increased through layer-by-layer grinding in the dye processing process, so that the dyeing rate of the dye in use is increased, and the fastness of the dye in later use is improved while the leveling property is improved.

Description

technical field [0001] The invention relates to a dye and a preparation process thereof, in particular to a vat black DC dye and a preparation process thereof, and belongs to the technical field of vat dyes. Background technique [0002] Most of the currently used dyes have the problem of poor color fastness. During the dyeing process of vat dyes, some dyes fail to enter the interior of the fabric and can only be adsorbed on the surface to form floating colors. These floating colors seriously affect the washing fastness of fabrics. Spend. Contents of the invention [0003] The main purpose of the present invention is to provide a vat black DC dye and a preparation process thereof in order to solve the deficiencies of the prior art. [0004] The purpose of the present invention can be achieved by adopting the following technical solutions: [0005] A vat black DC dye, in parts by weight, comprising: 33-54 parts of disperse blue, 25-34 parts of disperse red, 20-30 parts of...
