Problems solved by technology

[0003] In order to improve the dyeing efficiency of polyester-cotton blended fabrics in actual production, some enterprises adopt the simpler and more efficient one-bath method instead of the two-bath method for dyeing, that is, two-step methods are used to dye polyester-cotton fabrics in the same dyeing bath. However, when polyester-cotton is dyed by the one-bath method, the dyeing effect and color fastness are easily affected by the dyeing sequence of polyester-cotton, and then the defects of poor dyeing effect and color fastness are prone to occur, which limits its use

[0098]

[0099] Note: The color light of the dye composition of this application can be adjusted by the ratio of the general formula (I), general formula (II) and general formula (III) dyes, which can give it excellent color and luster, and can also make the blue reactive dye The composition has better color fastness and is less likely to decolorize after being applied to polyester-cotton fabrics.

Abstract

The invention relates to the technical field of dyes, in particular to a blue reactive dye composition and application thereof. The blue reactive dye composition comprises one or more dye compounds represented by a general formula (I), one or more dye compounds represented by a general formula (II) and one or more dye compounds represented by a general formula (III), general formula (II); and general formula (III). After the blue reactive dye composition is applied to polyester-cotton blended fabric dyeing through a one-bath method, the blue reactive dye composition not only has good dyeing performance, but also can guarantee various dyeing fastnesses, compared with a single dye, the blue reactive dye composition is remarkably improved, compared with a two-bath method, the process is simplified, the step of replacing a bath lotion is omitted, and then the dyeing efficiency is guaranteed.

Description

technical field [0001] The application relates to the technical field of dyes, more specifically, it relates to a blue reactive dye composition and its application. Background technique [0002] With the improvement of people's living standards, people have a higher pursuit of the color and comfort of clothing. Taking polyester-cotton fabric as an example, it has the advantages of both polyester and cotton fibers, and its dyeing quality depends on Due to the choice of dyes and dyeing methods, more and more mixed dyes and supporting dyeing processes have emerged, among which the most widely used reactive mixed dyes and the two-bath method are examples. [0003] In order to improve the dyeing efficiency of polyester-cotton blended fabrics in actual production, some enterprises adopt the simpler and more efficient one-bath method instead of the two-bath method for dyeing, that is, two-step methods are used to dye polyester-cotton fabrics in the same dyeing bath. However, when ...
