The present invention relates to a reactive dye for cellulose fibers. More particularly, the present invention relates to vinylsulfonyl-type reactive dyes for dyeing cellulosic fibers, particularly natural or regenerated cellulose fibers, in a fast and intense orange to scarlet color. The reactive dye for cellulose fibers of the present invention has the general formula [] (In the formula, D represents a benzene or naphthalene-based diazo component residue, R 1 represents hydrogen, a methyl group, or an ethyl group, and R 2 and R 3 represent hydrogen, a methyl group, a methoxy group, or a sulfonic acid group. ,
X represents an aliphatic or aromatic amino residue having one or two sulfonic acid groups. ) It is a vinylsulfonyl-type reactive dye represented by: The dye represented by the general formula [] of the present invention is:
For example, general formula [] (In the formula, D and R 1 have the same meanings as in the above general formula []) and the following general formula X-H (wherein, X is as in the above general formula []) The following general formula [] is obtained by condensing the aminos represented by (In the formula, D, R 1 and X have the same meanings as in the above general formula []) and the following general formula [] (In the formula, R 2 and R 3 have the same meanings as in the above general formula [].) It is easily produced by condensing the compound represented by the formula in an aqueous medium at 90 to 95°C. Examples of cellulose fibers that can be dyed with the reactive dye of the present invention include natural fibers such as cotton and hemp, regenerated fibers such as viscose rayon, and blends of cellulose fibers and synthetic fibers such as polyester fibers and polyacrylonitrile fibers. Can be mentioned. For dyeing cellulose fibers with the reactive dyes of the invention, an acid binder such as sodium bicarbonate,
Dyeing can be carried out by a conventional method in the presence of an inorganic alkali such as soda carbonate or an organic base such as triethylamine. For example, in the case of dyeing by dip dyeing, the dyeing can be carried out by a conventional method in the presence of an inorganic salt such as common salt or mirabilite salt and an acid binder at a temperature of 40 to 60°C. Furthermore, when dyeing by a textile printing method, dyeing can be carried out by a commonly used method, such as a method using sodium alginate, urea, a reduction inhibitor, or an acid binder. Also, various dyeing methods used for vinylsulfonyl type water-soluble reactive dyes, such as a pad batch method and a pad steam method, can be applied. The dye of the present invention has a very high dyeing rate and is also advantageous in terms of wastewater treatment after dyeing. On the other hand, the fastness is also very good, and the fastness to chlorine, which has become a problem in recent years, is at an amazingly high level compared to conventional dyes of the same color.The fastness to sweat and sunlight, which is a problem in terms of composite fastness, is also high, and the fastness to orange and It has extremely high practical value as a scarlet dye. Hereinafter, the method of the present invention will be specifically explained with reference to Examples, but the present invention is not limited to these Examples unless the gist thereof is exceeded. Example 1 Structural formula Dissolve 0.3g of the dye shown in 300ml of water,
15 g of cotton cloth was immersed in the dye bath prepared by adding and dissolving 15 g of cotton cloth, and the temperature was raised to 50° C. over 30 minutes. Next, 4.5g of soda carbonate was added and dyed at 50℃ for 1 hour, then washed with water.
After soaping, washing and drying, a scarlet dyed product was obtained. The degree of dyeing of this dye is very high.The dyed product obtained is extremely dense, and the chlorine fastness is grade 5 (available chlorine 2.0 ppm according to JIS0884), which is excellent.Light fastness, sweat-sunlight fastness. It was also good. The dye used in this example has the formula 1 mole of the compound represented by the formula and 1 mole of 3-aminobenzenesulfonic acid were stirred in an aqueous medium at 30 to 40°C for 3 hours while keeping the liquid neutral with sodium carbonate. After preparing the dye, it was stirred with 1 molar proportion of 3-(β-hydroxyethyl)sulfonylaniline sulfate in an aqueous medium at 90 to 95°C while maintaining the pH at 5 to 6 with sodium acetate for 10 hours, and then salted with potassium chloride. Obtained by analysis. Example 2 Structural formula A cotton cloth was printed using the dye shown in the following method. Dye 2.0g Urea 10.0g Sodium alginate 3.0g Sodium 3-nitrobenzenesulfonate 0.5g Sodium hexametaphosphate 0.5g Sodium bicarbonate 1.0g Water Remainder 100.0g In other words, the printing paste with the above composition was printed on cotton cloth.
After intermediate drying at 100°C, it was steamed at 100°C, followed by washing with water, soaping, washing with water, and drying. As a result, a deep orange dyed product with good light fastness and wet fastness was obtained, and the chlorine fastness of this dyed product was extremely excellent at grade 5 (available chlorine 20 ppm according to JIS 0884). The dye used in this example has the formula 1 molar proportion of dye and aniline-2,5-
Stir 1 mole of disulfonic acid in an aqueous medium at 30 to 40℃ for 3 hours while keeping the liquid neutral with sodium carbonate. After preparing the dye, it was stirred in an aqueous medium with 1 molar proportion of 4-(β-hydroxyethyl)sulfonylaniline sulfate at 90 to 95°C while maintaining the pH at 5 to 6 with sodium acetate for 10 hours, and then salted with potassium chloride. Obtained by analysis. Example 3 Cotton cloth was dyed using the dyes shown in the table below in a manner similar to Example 1 above, and the results are as follows.
