Abstract

The invention discloses an alkali-resistant color fixing agent. The alkali-resistant color fixing agent is prepared from, by weight, 10-16 parts of butyl methacrylate, 6-10 parts of 2,5-dichlorobenzoic acid, 2-8 parts of 2,4-hexadienoic acid, 9-15 parts of triethylene tetramine, 12-18 parts of 2-amino propanol, 8-14 parts of pinacolone menthanone, 12-20 parts of monopotassium phosphate, 20-26 parts of epibromohydrin, 15-24 parts of 4,5-diamido-2-nitrophenetol, 7-15 parts of 3,4-dihydroxyl benzedrine and 80-130 parts of distilled water. The alkali-resistant color fixing agent can adapt to an alkali operation environment and is high in dry rubbing fastness, wet rubbing fastness and soaping fastness.

Description

technical field [0001] The invention belongs to the field of color fixing agents, in particular to an alkali-resistant color fixing agent and a preparation method thereof. Background technique [0002] At present, most fabrics are dyed with reactive dyes. In the soaping environment, because the relationship between the hydrophilic group contained in its structure and the dyeing particle size itself will affect the soaping fastness of the dyeing, it is usually added The color fixing agent achieves the purpose of color fixing. There are many kinds of environments in the process of fabric dyeing, and there is no color-fixing agent that can adapt to the alkaline working environment and has good color-fixing effect in the existing technology. Contents of the invention [0003] Aiming at the above technical problems in the prior art, the present invention provides an alkali-resistant color fixing agent and a preparation method thereof, so as to adapt to the alkaline working env...
