Problems solved by technology

[0005] In addition, in addition to the problems associated with the dyeing bath ratio, there is also the problem of color differences caused by the temperature of alkali addition, resulting in poor reproducibility at both the laboratory scale and the factory scale.
[0006] In order to solve such problems, for example, various studies have been carried out in the following patent documents, but satisfactory results have not yet been obtained.
[0007] In addition, Japanese Patent Application Laid-Open No. 2000-192374 describes a red reactive dye composition excellent in dyeing reproducibility, but its solubility is insufficient and it is difficult to put it into practical use.

Embodiment 3～ Embodiment 12

[0230] Using the combination and usage amount of the dyes shown in Table 5 instead of the combination and usage amount of Compounding Example 1 in Example 1, water was added to 15 parts of anhydrous sodium sulfate to prepare a total of 490 parts of dye baths. 50 parts of knitted cotton fabrics were placed in this dye bath, and the temperature was raised to 60° C. over 20 minutes. After treating at 60°C for 10 minutes, add 10 parts of sodium carbonate and dye at the same temperature for 60 minutes. Then, after washing with water and hot water, saponify at 100° C. for 15 minutes in 500 parts of an aqueous solution containing a commercially available saponification agent (Skoalol C-1200, manufactured by Kitahiro Chemical Co., Ltd., 1 g / L), and then perform Washing with water and drying to obtain a dyed product.

Abstract

The existing dyes used as primitive colors different affinity to cellulose base fiber and different dyeing behaviors, such that there is a problem of difference colors due to concentration or color shade variation along with the variation of dye bath ratio, and coloration correction and decolouration correction must be performed frequently in a workshop. Therefore, primitive colors having an identical dye bath ratio variation behavior are required in a dyeing workshop. In addition, there is a problem of color difference due to alkalization temperature, and reproducibility badness is brought in laboratory scale and plant scale. The present invention provides a reactive dye composition and a dyeing method using the same, wherein a reactive dye composition combination contains red reactive dye composition containing special dyes represented by formula (1), formula (2) and formula (3), blue reactive dye composition containing more than one dyes represented by formula (4), formula (5) and formula (6), dark blue reactive dye composition containing dyes represented by formula (5), and formula (7), and yellow reactive dye represented by formula (8).

Description

technical field [0001] The present invention relates to a reactive dye (reverse dye) composition suitable for dyeing cellulose fibers or fibers containing cellulose fibers and a dyeing method using the reactive dye composition. Background technique [0002] In the dyeing of cellulose fibers using reactive dyes, it is known to use reactive dyes of yellow, red, blue, or navy blue (cyan) as dyes for three primary colors, and to blend them in various ratios for dyeing. [0003] For the reactive dyes used as the three primary colors, it is required that the dyes have good build-up properties and level dyeing properties, the dyeing speed of the three primary colors is basically equal and the temperature dependence is consistent, and the various fastnesses of the three primary colors are excellent. In addition, special requirements can meet the needs of the actual process. That is, in general, in order to make the dyed product into a product, it will go through the steps of labora...
