Embodiment 1～4 and comparative example 1～9

[0031] 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.

[0032] 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 a dye, a dye composition and a dye raw material composition. The invention provides the dye raw material composition which comprises a dye monomer A as shown in formula (1) and a dye monomer B as shown in formula (2); and a ratio (in parts by weight) of the dye monomer A to the dye monomer B is 2.5:1 to 5.5:1. The invention further discloses a dye composition comprising the dye raw material composition, and dye prepared from the dye composition; hue of the dye is close to active blue 19#, the dye can be subjected to white discharging through a normal discharge printing process, has excellent discharge performance, can replace bright blue 19# which cannot be discharged previously, and is applied to the discharge printing process to produce high-grade printed products, so that a product additional value is increased. (The formula is shown in the description.).

Description

technical field [0001] The invention relates to a dye, a dye composition and a dye raw material composition. 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 mo...
