When dyeing polyester-cotton blended fabrics, disperse/reactive dyes are generally selected to dye polyester fibers by a two-bath two-step method, namely, the disperse dyes are used for dyeing polyester fibers at 130 ℃ and then the reactive dyes are used for dyeing cotton fibers at 60 ℃, the two dyeing processes are respectively carried out in two dyeing baths, and although the process can obtain better dyeing effect, the process production flow is long and the energy consumption is high. The dyeing industry gradually adopts a one-bath two-step method to dye the polyester-cotton blended fabric, namely the polyester-cotton blended fabric is dyed in the same dyeing bath step by step, and compared with the previous two-bath two-step method, the production efficiency is greatly improved.
In recent years, in order to further improve the production efficiency and reduce the energy consumption, a one-bath one-step dyeing method is further researched on the basis of a one-bath two-step method, namely, a disperse dye and a reactive dye are used for preparing a dye bath, and then polyester cotton is dyed at a certain temperature (generally 100-130 ℃).

As is clear from the data in tables 6 to 9, at a dyeing temperature of 60 ℃ (conventional), the color change grades of the raw fabrics under the conditions of acidic perspiration and alkaline perspiration of the reactive dye compositions A to K in the examples can reach 5 grades, no obvious color change occurs, the color change grade of the raw fabrics under the conditions of both the acidic perspiration and the alkaline perspiration of the reference dyes A to E in the comparative examples can reach 4 to 5 grades, the color change grade of the raw fabrics under the conditions of both the acidic perspiration and the alkaline perspiration is 4 grades, in addition, at a dyeing temperature of 130 ℃ (high temperature), the color change grade of the raw fabrics under the conditions of both the acidic perspiration and the alkaline perspiration of the reactive dye compositions A to K in the examples can still reach 4 to 5 grades, the color change grade of the raw fabrics under the conditions of both the perspiration of the reference dyes A to E in the comparative examples can be obviously reduced to 3 grades, and the color change grade of the raw fabrics under the conditions of only 2 grades or 2 to 3 grades. Therefore, the compound of the general formula (I) and the compound of the general formula (II) have synergistic promotion effect, and the perspiration fastness of the reactive dye composition at 130 ℃ can be greatly improved.
Test 5: water fastness test
The cloth sample a treatment method comprises the following steps: respectively providing dye bath compositions with the reactive dye compositions A-K and the reference dyes A-E, wherein the dosage of the dye bath compositions is 3% (o.w.f), putting pure cotton fabric into the dyeing bath at the temperature of 28 ℃, the bath ratio is 1:10, heating to 60 ℃ at the speed of 2 ℃/min, preserving heat and dyeing for 40min, and sequentially washing, soaping and water washing the dyed fabric.
The cloth sample b treatment method comprises the following steps: the difference from the cloth sample a treatment method is only that the dyeing temperature is 130 ℃.
The water fastness test was performed on the dyed fabric samples a, b according to the specifications of ISO 105-C10-2006 (3) (60 ℃ for 30 min), and the results are shown in tables 10, 11 below.
Table 10

TABLE 11
As can be seen from the data in Table 10 and Table 11, the color change grade of the base fabrics of the reactive dye compositions A to K in the examples can be 4 to 5, the color change grade of the six fibers can be 3 to 4, 4 or 4 to 5, and the color change grade of the base fabrics of the reference dyes A to E in the comparative examples can be 4, the color change grade of the six fibers can be 3 to 4 or 4, at the dyeing temperature of 60 ℃ in the conventional manner. At 130 ℃ (high temperature) dyeing temperature, the color change grade of the primary cloth of the reactive dye composition A-K in the examples still can reach 4-5 grades, the six-fiber staining grade still can reach 3-4 grades or 4 grades, the color change grade of the primary cloth of the reference dye A-E in the comparative examples is only 3 grades, and the six-fiber staining grade can only reach 2 grades or 2-3 grades. Therefore, the compound of the general formula (I) and the compound of the general formula (II) have synergistic promotion effect, and the water-resistant color fastness of the reactive dye composition at 130 ℃ can be greatly improved.
Test 6: light color fastness test
The cloth sample a treatment method comprises the following steps: respectively providing dye bath compositions with the reactive dye compositions A-K and the reference dyes A-E, wherein the dosage of the dye bath compositions is 3% (o.w.f), putting pure cotton fabric into the dyeing bath at the temperature of 28 ℃, the bath ratio is 1:10, heating to 60 ℃ at the speed of 2 ℃/min, preserving heat and dyeing for 40min, and sequentially washing, soaping and water washing the dyed fabric.
The cloth sample b treatment method comprises the following steps: the difference from the cloth sample a treatment method is only that the dyeing temperature is 130 ℃.
The dyed cloth samples a, b were tested for light fastness according to the specification of GB/T8426-1998, the results being included below
Table 12.
Table 12
As can be seen from the data in Table 12, the light fastness ratings of reactive dye compositions A-K in the examples can reach a rating of 7-8, while the light fastness ratings of reference dyes A-E in the comparative examples are only 6-7, at 60℃dyeing temperature (conventional). At a dyeing temperature of 130 ℃ (high temperature), the light fastness grade of the reactive dye compositions A-K in the examples still reached 7, whereas the light fastness grade of the reference dyes A-E in the comparative examples was only 4-5 or 5, far lower than the reactive dye compositions in the examples. It follows that the reactive dye compositions A-K have better light fastness than the reference dyes A-E. Thus, the compound of the general formula (I) and the compound of the general formula (II) have synergistic promotion effect, and the light fastness of the reactive dye composition at 130 ℃ can be greatly improved.
