INDUSTRIAL APPLICATION FIELD The present invention relates to a novel disazo-based reactive dye. BACKGROUND ART In recent years, there has been an increasing demand for blended fabrics of cellulose fibers and other fibers, particularly blended fabrics with polyester fibers (hereinafter simply referred to as C/P fibers). Traditionally, when dyeing cellulose fibers, reactive dyes are used in the presence of acid binders such as sodium carbonate, potassium carbonate, and sodium hydroxide, and electrolytes such as sodium chloride and sodium sulfate.
The dyeing process is carried out at a pH of 10 or higher and a temperature of 100°C or lower.When dyeing polyester fibers, disperse dyes are used and dyeing is carried out at a temperature of about 130°C. When dyeing fibers, a two-bath method is generally used in which one fiber, cellulose or polyester, is dyed and then the other fiber is dyed in a separate bath. However, in order to simplify the dyeing process, the above C/
If P fibers were to be dyed in the same process (one-bath method), two different dyes would be used in combination, a reactive dye and a disperse dye. When using disperse dyes, it is necessary to raise the pH to 10 or higher using an acid binder in order to fully dye the reactive dye on the cellulose fiber side, but the presence of an acid binder accelerates the decomposition of the disperse dye. The dyeing of the disperse dye to the polyester fiber is insufficient, and high temperature conditions (usually 130°C) are required to dye the disperse dye to the polyester fiber side, but under the high temperature mentioned above, There were problems such as accelerating the hydrolysis of reactive dyes and significantly inhibiting the dyeing of cellulose fibers. Problems to be Solved by the Invention The object of the present invention is to provide a disazo-based reactive dye that can dye cellulose fibers under the pH and dyeing conditions when dyeing polyester fibers with disperse dyes. It is something. Means for Solving the Problems The present invention is based on the general formula [] (In the formula, M represents a hydrogen atom or an alkali metal, X represents a hydrogen atom, a lower alkyl group, a lower alkoxy group, an acetylamino group, or a carbamoylamino group, and Y represents a hydrogen atom, a lower alkyl group, or a lower alkoxy group. and m represents 2 or 3). In the disazo-based reactive dye represented by the general formula [] of the present invention, the alkali metal represented by M includes sodium, potassium, etc., and the lower alkyl group and lower alkoxy group represented by X and Y include: Examples include alkyl groups and alkoxy groups having 1 to 4 carbon atoms. The disazo-based reactive dye represented by the general formula [] can be produced as follows. For example, the following general formula [] (In the formula, M, X, Y and m are the same as defined above) and the following general formula [] (wherein M, X, Y and m are the same as defined above) can be condensed to produce a disazo-based reactive dye represented by the general formula []. Action/Effect Fibers that can be dyed with the disazo-reactive dye of the present invention include cellulose fibers such as cotton, viscose rayon, cuprammonium rayon, and hemp, and nitrogen-containing fibers such as polyamide, wool, and silk. . Furthermore, cellulose fibers in mixed fibers such as polyester, triacetate, polyacrylonitrile, polyamide, wool, silk, etc. containing cellulose fibers can of course be dyed well. In the fiber dyeing method using the disazo-based reactive dye of the present invention, dyes necessary for dyeing non-cellulose fibers, such as Color Index
(3rd edition) can be added to the dye bath at the same time for dyeing. When dyeing cellulose fibers using the disazo-based reactive dye of the present invention, for example, using the disazo-based reactive dye represented by the above general formula [] and maintaining the dye bath at pH 5 to 10 during dyeing, Necessary buffering agents (for example, acids such as carbonic acid, phosphoric acid, acetic acid, citric acid, and sodium salts or potassium salts of these acids, usually 0.5 to 5.0 g/mixture) and electrolytes as necessary (chlorinated A dye bath containing sodium or sodium sulfate (usually about 1 to 150 g) is prepared, and cellulose fibers are added to this dye bath and heated at a temperature of 100 to 150 degrees Celsius for 30 to 50 minutes. It is possible to perform various staining. In addition, blended fabrics manufactured by adding other fibers such as polyester fibers to cellulose fibers,
In order to dye mixed woven and knitted fabrics, etc., a disazo-based reactive dye represented by the above general formula [] of the present invention,
By adding the disperse dye listed in the Color Index to the dye bath, cellulose fibers and polyester fibers can be dyed simultaneously by a one-bath, one-stage method. In addition, when dyeing blended fabrics, blended knitted fabrics, etc., as described above, the conventional one-bath two-step method of dyeing one fiber and then dyeing the other fiber in the same bath is used. May be applied, and furthermore,
It is also possible to adopt a two-bath method in which cellulose fibers and other fibers are dyed from separate baths by combining the dyeing method using the disazo-based reactive dye of the present invention and the dyeing method for fibers other than cellulose fibers. It is. EXAMPLES Hereinafter, the method of the present invention will be specifically explained using examples, but the present invention is not limited to the following examples. Example 1 Structural formula below The monoazo dye 1 molar ratio represented by and the following structural formula After condensing 1 molar proportion of the monoazo dye represented by produced dyes. 0.2 g of the disazo-based reactive dye of the present invention represented by the above structural formula, 16 g of Glauber's salt, and as a buffering agent.
Add 0.4 g of Na 2 HPO 4 12H 2 O and 0.1 g of KH 2 PO 4 to water.
Add 10g of unmercerized cotton knitted fabric to a dye bath adjusted to PH7 and raise the temperature to 120℃ over 30 minutes. After dyeing at the same temperature for 60 minutes, wash, soap, wash and dry to create a yellow color. A dyed product was obtained. The degree of dyeing of this dye was very good, and the dyed product obtained was extremely dense, and the light fastness, chlorine fastness, and sweat fastness to daylight were all good. Example 2 Structural formula below The monoazo dye 1 molar ratio represented by and the following structural formula A disazo-reactive dye of the present invention represented by the following structural formula (free acid form) was produced by condensing 1 molar proportion of the monoazo dye represented by . 0.2 g of the disazo-based reactive dye of the present invention represented by the above structural formula, 16 g of Glauber's salt, and as a buffering agent.
Add 0.5 g of Na 2 HPO 4 12H 2 O and 0.02 g of KH 2 PO 4 to water.
Add 10g of unmercered cotton knitted fabric to the prepared dye bath and heat up to 130℃ over 30 minutes.
After dyeing at the same temperature for 30 minutes, washing with water, soaping,
After washing with water and drying, a reddish yellow dyed product was obtained. This dyeing bath had a pH of 8 before and after dyeing. The dyed product obtained was extremely dense and had good light fastness, chlorine fastness, and sweat fastness. Example 3 The following structural formula used in Example 1 The monoazo dye represented by the following structural formula Instead of the monoazo dye represented by, and the following structural formula The monoazo dye represented by the following formula A disazo-reactive dye of the present invention represented by the following structural formula (free acid form) was produced according to the method described in Example 1, except that the monoazo dye represented by was used instead. 0.2 g of the disazo type reactive dye of the present invention represented by the above structural formula, the following structural formula: 0.2g of quinophthalone dye, 12g of mirabilite,

This dyeing bath had a pH of 8 before and after dyeing. Furthermore, the dyeing property was very good, and the dyed product obtained was extremely rich, and the light fastness, chlorine fastness, and sweat fastness to daylight were all good. Example 4 According to the method described in Example 1, the disazo-based reactive dyes of the present invention shown in Table 1 below (in the form of free acids) were produced, and cotton fabrics were made with the obtained disazo-based reactive dyes. It was stained and the results are shown in Table 1.
