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 known compounds in the prior art.

[0027] Examples 1-4 and Comparative Examples 1-9 all use monomer dry powder blending, using a common conical blender in the dye industry, blending for 3 hours, and returning the material once per hour, a total of 3 times, fully blended evenly, The difference between the upper and lower sampling intensity is not more than 2% to meet the standard.

Abstract

The invention discloses application of dye to dyeing. The invention provides the application of the dye to dyeing. The dye is prepared by mixing a dye raw material composition and an aid; and the dye raw material composition comprises a dye monomer A as shown in a formula (1) and a dye monomer as shown in a formula (2) according to the weight part ratio being 2.5:1 to 5.5:1. The dye is applied to a discharge printing process, the hue is close to active blue 19 and can replace brilliant blue 19 which cannot be discharged originally, white discharging can be conducted by the conventional discharge printing process, excellent discharging performance is achieved, high-grade printing products can be produced, and the additional value of the products is increased. (The formulas are as shown in the description).

Description

technical field [0001] The invention relates to the application of a dye in dyeing. Background technique [0002] Discharge printing, also known as carving printing, is the process of printing discharge dyeing paste on colored fabrics to eliminate local colors, and at the same time, another dye can be added to the discharge dyeing paste to form colored ground color flowers. [0003] This process uses the strong reducibility of the white powder to destroy the background color. It is generally divided into two types: neutral and alkaline discharge. The difference is whether to add alkali agent. The choice of alkali agent can be caustic soda (30%, 36°Bé (Baume)) / Soda Ash / Potassium Carbonate. In terms of dye selection, the activity of vinyl sulfone type is generally not alkali resistant, and it 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 more difficult to pull out ...
