Compound reactive brilliant blue dye composition as well as application and use method of compound reactive brilliant blue dye composition

Abstract

The invention relates to a compound reactive brilliant blue dye composition as well as an application and a use method of the compound reactive brilliant blue dye composition, and particularly relates to a reactive dye compound product suitable for dyeing cellulose fiber or cellulosic fiber. The compound reactive brilliant blue dye composition is composed of an auxiliary and an active substance composed of two or more selected from five dye components. The compound reactive brilliant blue dye is excellent in washing fastness, light fastness and rubbing fastness, bright in colored light, and capable of showing the color and luster same as those of jewelry blue; the compound reactive brilliant blue dye is simple in process and easy to control during dyeing, and the price of the dye is more than 30% lower than that of a vat dye Indian blue in the traditional technology under the condition that the performance of the product is unchanged, so that the compound reactive brilliant blue dye is high in economic benefit; the compound reactive brilliant blue dye is good in alkaline resistance, capable of dyeing cold pad batches, high in fixation rate and good in dyeing stability; the compound reactive brilliant blue dye is moderate in directness, and capable of realizing the balance of a dye migration phenomenon and a dyeing supplement problem.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a reactive dye composite product suitable for dyeing cellulose fiber or cellulose-containing fiber, specifically a composite reactive brilliant blue dye composition with high fastness and its application and application method . Background technique [0002] In the dyeing of cellulose fibers using reactive dyes, reactive brilliant blue dyes have always been a hot item in the market, mainly showing excellent light and bright colors. Brilliant blues are generally anthraquinone type, triphenyldioxazine type, formazan Type reactive dyes, most of them have excellent fastness. And all kinds of brilliant blues have certain defects, such as: anthraquinone-type brilliant blues have poor alkali resistance when used alone, and are easy to dye flowers and other defects, such as reactive blue 19. agent to prevent discoloration and hydrolysis. When triphenyldioxazine-type brilliant blue is used alone, ...

AI Technical Summary

Problems solved by technology

And all kinds of brilliant blues have certain defects, such as: anthraquinone-type brilliant blues have poor alkali resistance when used alone, and are easy to dye flowers and other defects, such as reactive blue 19. agent to prevent discoloration, hydrolysis

When triphenyldioxazine-type brilliant blue is used alone, the color light is too green, and there are few medium-temperature dyes, so the application area is too narrow

And A When the type of brilliant blue is used alone, the shade is darker, and the dye is not easy to dye dark

In order to solve these problems of Yanlan, various studies have been carried out in many patent documents, but satisfactory results have not yet been obtained.
