Red reactive dye and cotton fiber dyeing method thereof in non-aqueous media

The invention discloses red reactive dye. The structure of the red reactive dye is as shown in formula I, wherein R1 and R2 are independently selected from hydrogen and substituted or non-substitutedC1-C4 alkyl; X is F, Cl or Br; R3 and R4 are independently selected from C1-C4 alkoxy, halogen, hydroxyl and sulfonic group; D1 and D2 are independently selected from substituted phenyl. The red reactive dye has high solubility in non-aqueous media and high affinity to cotton fibers and can dye the cotton fibers in a high dye uptake manner, and corresponding part of hydrolyzed dye which is not fixed to the fibers can be easily washed.

Triazinylaninlino-disazo dyes, methods of preparing them and their use for dyeing and printing fiber materials

The present writing relates to a novel fiber-reactive dye of the formula wherein R11, D, R0, X and Z are as defined in the specification. The novel dye according to the present writing can be used in dyeing and printing fibre materials, especially, cellulosic fibre materials by a general fixing method, and a good adsorbing/fixing rate and an excellent fastness to light and wet treatment.
