Description

Technical Field

[0001] The present invention relates to the technical field of dyes, and more specifically, to a composite high sunlight fastness reactive red dye composition and its use. Background Art

[0002] With the continuous development of cellulose fiber varieties and the continuous development of dyeing technologies, when using reactive dyes to color cellulose fibers, higher and higher requirements are put forward for the application performance of reactive dyes. In recent years, many review articles on reactive dyes have been published, covering not only the development of reactive dyes themselves, but also their application performance and processes, with the focus on improving their application performance and environmental friendliness. Among them, particular attention is paid to sunlight fastness in terms of application performance. Many product standards in the textile industries of China and the world take the comprehensive performance of dyes as an important assessment indicator. China has specifically formulated the standard requirements of "GB / T 31888-2015 for School Uniforms of Primary and Middle School Students", putting forward new requirements for indicators such as the sunlight fastness of textiles. Under this background, there is an urgent need to develop a high sunlight fastness dye with comprehensive application performance and excellent performance in various aspects to be used in textiles.

[0003] The sunlight fastness index is a shortcoming for reactive dyes. Most of the sunlight fastness indexes of reactive dyes do not meet the standards and do not meet the requirements of school uniforms or brand clothing. School uniforms or brand clothing specifications require a sunlight fastness of level 4 or above. Moreover, the red series in reactive dyes is particularly prominent in terms of the defect of sunlight fastness. Most reactive red dyes have a sunlight fastness of only level 2-3. To solve the problem of the sunlight fastness of reactive red dyes, various studies have been carried out in many patent literatures, but satisfactory results have not been obtained. Therefore, there is an urgent need to develop a reactive red dye with high sunlight fastness and stable application performance in all aspects to meet the market demand. Summary of the Invention

[0009]

[0010] wherein, M1, M2, and M3 each independently represent -H, -Na, -K or -Li;

[0011] R1 represents -H or -SO3M; M represents -H, -Na, -K or -Li; R2 represents -H or -C2H5; X represents -Cl or -F;

[0012] The ortho position of the azo group has a hydroxyl group with coordination ability, forming a stable chelate ring with copper ions.

[0013] Furthermore, M1, M2, and M3 each independently represent -H, -K or -Li; R1 represents -SO3M, M represents -Na, -K or -Li; X represents -F.

[0014] Furthermore, the compound represented by formula (1) is formula (1-1), formula (1-2), formula (1-3), formula (1-4) or formula (1-5);

[0029] 3. Beneficial effects

[0030] Compared with the prior art, the advantages of the present invention are as follows:

[0031] (1) The product obtained in the present invention is a copper complex structure dye, while most of the reactive red dyes in the market (reactive red 195, reactive red 194, reactive red 111, reactive red 198, reactive red 250, reactive red RGB, reactive red S-B) are azo type structure dyes. For example, the dye provided in the patent CN104927396B "A Composite Reactive Deep Red Dye and Its Preparation Method and Application" is also an azo type structure dye. When dyeing light to medium colors, especially light colors, due to the poor sunlight fastness of azo type red dyes, the actual use requirements cannot be met. In contrast, the product obtained in the present invention has a copper complex structure. Since the two adjacent positions of the azo group contain hydroxyl groups with coordination ability, a stable chelate ring can be formed with copper, thereby improving the sunlight fastness.

[0032] (2) The composite high sunlight fastness reactive red dye provided by the present invention can be medium-temperature colored on cellulose fibers or cellulose-containing fibers. During dyeing, it has excellent performance parameters in terms of directness, levelness, synchronism, and hue reproducibility, and is not easy to dye unevenly. The dyed fibers can not only meet the high sunlight fastness red color requirements, but also have excellent application properties such as rubbing fastness, washing fastness, and perspiration fastness.

[0033] (3) The composite high sunlight fastness reactive red dye provided by the present invention is compounded with reactive dyes having different application properties. The various indicators of the dyed finished product obtained by using the dye of the present invention are superior to those of traditional single red reactive dyes, and it is particularly suitable for the dyeing requirements of primary and secondary school student school uniform fabrics. Specific embodiments

[0034] Each of the dyes contained in the present invention, namely, those of formula (1), formula (2) and formula (3), can be prepared by those skilled in the art by known methods respectively.

[0035] In the composite high-sunlight fastness reactive red dye composition provided by the present invention, there is no particular limitation on the compounding method of each reactive dye. The following methods can be adopted: the method of separately manufacturing each reactive dye first and then compounding them; for example, the method of mixing the reaction solutions containing each reactive dye generated during manufacturing and then drying to obtain the composition; or the method of dissolving each reactive dye in a dyeing bath to obtain the same composition as each composition in the dyeing bath, etc. At this time, the mixing ratio of the dyes of formula (1), formula (2) and formula (3) in the composite high-sunlight fastness reactive red dye composition can be appropriately compounded according to the required hue, and can be compounded according to the fastness index in the application performance. Among them, the auxiliaries in the composite reactive red dye can be mixed with the reactive dyes in the composite high-sunlight fastness reactive red dye in any weight ratio according to needs.

[0036] When preparing a dyeing bath by adding each dye of the composite high-sunlight fastness reactive red dye composition of the present invention and additives used as needed to a dyeing bath or a padding dyeing bath and then carrying out dyeing. The dissolution order of each dye, additive and some required substances can be in any order, and the usage amounts of each component can also be determined with reference to known methods.

[0037] The composite high-sunlight fastness reactive red dye composition is useful for cellulose fibers and fibers containing cellulose fibers, such as cotton, linen, rayon and wool. In its dyeing method, the usage amount of the composite high-sunlight fastness reactive red dye composition is usually 0.005%-15% of the fiber weight. Preferably, the usage amount of the composite high-sunlight fastness reactive red dye composition is usually 2% of the fiber weight.

[0038] The dyeing usage method of the composite high-sunlight fastness reactive red dye composition can be carried out according to methods well-known in the art, but is not limited thereto. For example, in the dyeing of cellulose fibers such as cotton, the reactive dye composition of the present invention that meets the required hue and concentration is added to the dyeing bath, and an inorganic neutral salt and a base binder are used separately or in combination. At this time, there is no particular limitation on the usage amount of the inorganic neutral salt or base binder used. In addition, the addition of the inorganic neutral salt or base binder to the dyeing bath can be carried out at one time or in batches. In addition to this, dyeing aids well-known in the art can also be used in combination, but the dyeing aids are not limited thereto. The dyeing temperature is 40°C - 90°C, and the preferred dyeing temperature is 50°C - 70°C.

[0039] The use of the composite high sunlight fastness reactive red dye composition can adopt a continuous dyeing method. The alkali binder can be added to the dye padding liquor alone or in combination with the composite high sunlight fastness reactive red dye composition. After padding according to a known method, it is dried, and then dyed by dry heat or steam heat according to a known method by a single-bath padding method, or it can be padded with the dye and then dried, and then padded in a known inorganic neutral salt, and dyed by dry heat or steam heat according to a known method by a two-bath padding method. However, the continuous dyeing method is not limited to this.

[0074] Examples 16 to 30:

[0075] 100 g of cotton cloth was dyed with the composite high-sunlight fastness reactive red dye composition obtained in Examples 1 to 15 at 2% of the fabric weight in a dye bath containing 60 g / L of sodium sulfate and a bath ratio of 1:20. It was adsorbed at 60 °C for 30 min, and then fixed with soda ash for 45 min. The amount of soda ash used was 15 - 20 g / L.

[0078]

[0079] According to this table, it can be seen that the application performance of yellowish red 2 and yellowish red 5 is more superior in the sunlight fastness index of yellowish red.

Blueish red 7 is compounded from formula (1-1), formula (1-3), formula (1-4), and formula (3-2), and blueish red 10 is compounded from formula (1-1), formula (1-3), formula (1-5), and formula (3-2). That is, formula (1-4) can make the dye have a higher light and perspiration composite effect;

Bordeaux 11 is compounded from Formula (1-1), Formula (2-2) and Formula (3-1), while Bordeaux 13 is compounded from Formula (1-3), Formula (2-2) and Formula (3-1). That is, Formula (1-1) can endow the dye with higher light fastness to perspiration, water fastness and soaping fastness;

[0085] Comparing Bordeaux 12 with Bordeaux 14, the comprehensive performance index of Bordeaux 14 is higher than that of Bordeaux 12.

[0089] For 100 g of cotton fabric, use the composite high-sunlight fastness reactive red dye composition obtained in Example 31 at 2% of the fabric weight. In a dye bath containing 60 g / L of sodium sulfate and with a liquor ratio of 1:20, adsorb at 60 °C for 30 min, add soda ash for fixation for 45 min, with the soda ash dosage being 15 - 20 g / L. After washing, soaping and drying, the obtained dyed cotton fabric has a uniform color, excellent sunlight fastness and wet rubbing fastness. The specific application performance parameters are shown in Table 3 as follows:

[0090]

[0091] Example 33:
