preparation example Construction

[0083] The preparation method of the navy blue reactive dye composition of the present invention comprises mixing the above-mentioned dyestuff of the general formula (1) and the dyestuff of the general formula (2) according to the prescribed weight ratio. Various conventional methods can be used for mixing, such as mechanical mixing methods. When mixed, the dyes of general formula (1) and general formula (2) may be present in powder form, or in granular form, or in aqueous solution. For example, the mixing step can be carried out in suitable mills such as ball mills or pin mills as well as in kneaders or mixers.

[0084] The navy blue reactive dye composition of the present invention is suitable for dyeing a wide variety of materials, especially materials containing carboxylic acid and / or carboxamide groups, more particularly fiber materials such as cotton, flax and hemp fibers, and fiber Vegan and regenerated cellulose, polyester or polyamide fiber materials, etc.

Embodiment 1

[0110] Shade of navy blue reactive dye composition of the present invention

[0111] The color of the dye represented by the general formula (I) is bright blue. Because the shade is very bright, it is not suitable for use as the three primary colors, and its application range is small. The color of the dye represented by the general formula (II) is dark blue.

[0112] The color shade of the reactive dye composition of the present invention can adjust the ratio of the dyes of the general formula (I) and the dyes of the general formula (II) according to the needs, so that the mixture can effectively form three primary color combinations with other red and yellow dyes, and improve its practical application value.

Embodiment 2

[0114] Salt and Alkali Solubility Test

[0115] Measure the saline-alkali solubility of the following dyes according to the above method, and the test results are recorded in Table 2

[0116] Table 2

[0117]

[0118]

[0119] It can be seen from Table 2:

[0120] The navy blue reactive dye composition of the present invention has better saline-alkali resistance solubility and better level dyeing property.

Abstract

The invention provides a navy reactive dye composition and dyeing application thereof in a fiber. The dye composition comprises one or more of dye compounds represented by a general formula (1) and one or more of dye compounds represented by a general formula (2). The navy reactive dye composition provided by the invention has excellent promoting power, leveling property and various dye fastness and has excellent compatibility with other common red and yellow reactive dyes to perform co-dyeing.

Description

technical field [0001] The invention relates to a reactive dye composition and its dyeing application on fiber materials. Specifically, the present invention relates to a navy blue reactive dye composition and its dyeing application on fiber materials. Background technique [0002] Triphenyldioxazine-type reactive dyes are a new chromogenic system developed and applied following the anthraquinone-type reactive dyes that have dominated blue reactive dyes for many years. [0003] The color intensity of triphenyldioxazine reactive dyes is higher than that of anthraquinone and azo reactive dyes, which is 4-6 times that of anthraquinone reactive dyes. directness. [0004] The parent structure of triphenyldioxazine is a planar, linear five-membered polycyclic ring, which is orange in color. Amino groups that introduce amino groups or substituents into the parent structure are blue. If a hydroxyl or alkoxy group is introduced, it will be red. These introduced groups generally ...
