Embodiment 1～4 and comparative example 1～9

[0026] Reactive Brilliant Blue No. 19, Dye Monomer A, Dye Monomer B, Reactive Blue 203 and Reactive Red 21 can be prepared by methods well known in the art, and are compounds known in the prior art.

[0027] Examples 1-4 and Comparative Examples 1-9 are mixed with monomer dry powder, using a common cone mixer in the dye industry, mixing for 3 hours, feeding once per hour, a total of 3 times, fully mixing and evenly mixing, The above sampling intensity difference does not exceed 2% to meet the standard.

Abstract

The invention discloses a dye preparation method. The dye preparation method disclosed by the invention comprises the step of mixing a dye composition containing a dye monomer A shown by a formula (1) and a dye monomer B shown by a formula (2), wherein according to parts by weight, the dye monomer A to the dye monomer B is 2.5 to (1 to 5.5 to 1). The hue of prepared dye is close to No. 19 reactive blue, can be white discharged by a general discharge printing technology, has excellent dischargeable performance, can substitute No.19 brilliant blue which cannot be discharged, can be applied to the discharge printing technology to produce top-grade printed products and improves additional value of products. (The formula (1) and the formula (2) are shown in the description.).

Description

Technical field [0001] The invention relates to a method for preparing dyes. Background technique [0002] Discharge printing, also known as engraving, is the process of printing discharge paste on colored fabrics to eliminate the partial color, and at the same time, add another dye to the discharge paste to form colorful flowers. [0003] This process uses the strong reducibility of the white powder to destroy the background color. It is generally divided into neutral and alkaline discharge dyeing. The difference is whether to add an alkali agent. The choice of alkali agent can be caustic soda (30%, 36°Bé (Baume degree)) / soda ash / potassium carbonate. In terms of the choice of dyes, the activity of the vinyl sulfone type generally makes use of its non-alkali resistance and can be whitened under neutral or alkaline reducing conditions. Most of the dyes of monochloro-s-triazine or dichloro-s-triazine can be used in alkaline It is difficult to extract white under the conditions of a...
