Reactive blue M-2GE is a commonly used reactive dye, which is a kind of reactive dye. Reactive blue M-2GE contains active groups that can react with hydroxyl groups in cellulose and amino groups in protein fibers, and form covalent bonds with fibers during dyeing to form "dye-fiber" compounds. The Reactive blue M-2GE produced by Milestone Industrial Co. Ltd. is mainly used for the dyeing of cotton, linen, viscose and other fibers. It can also be used for the dyeing and printing of silk, wool and other fibers.

Application performance of Reactive blue M-2GE:

1) The structure of Reactive blue M-2GE dye

Reactive blue M-2GE is a H acid bis-azo reactive dye containing monochloros-triazine and vinyl sulfone double reactive groups. Reactive blue M-2GE dye has good soap fastness and perspiration fastness, but the light fastness is not very good.

2) Affinity of Reactive blue M-2GE dye

The RF of Reactive blue M-2GE dye is greatly affected by sodium sulfate and soda ash, so during the dyeing process, sodium sulfate and soda ash should be added slowly to avoid color blur or color difference.

3) The change of the dye bath ratio has no obvious influence on the color yield of Reactive blue M-2GE, so the color yield of Reactive blue M-2GE is relatively stable during the dip dyeing process, and the influence of the bath ratio is relatively small.
