Embodiment 1

[0134] The shade of dark blue reactive dye composition of the present invention

[0135] The color of the dye represented by the general formula (I) is sky blue, and the color of the dye represented by the general formula (II) is red light blue.

[0136] The color light of the reactive dye composition of the present invention can adjust the ratio of the dyes of the general formula (I) and the dyes of the general formula (II) according to the needs, so that the mixture can effectively form three primary color combinations with other red and yellow dyes, and improve its practical application value.

Embodiment 2

[0138] Salt and Alkali Solubility Test

[0139] Measure the saline-alkali solubility of the following dyes according to the above method, and the test results are recorded in Table 2

[0140] Table 2

[0141]

[0142] It can be seen from Table 2:

[0143] Compared with the dye represented by the general formula (I), the deep blue reactive dye composition of the present invention has significantly improved solubility in salt and alkali resistance, thereby improving the level dyeing property of the dye represented by the general formula (I).

Embodiment 3

[0145] Lift rate test (K / S value at absorption wavelength 620nm)

[0146] Determination of the lifting rate of the following dyes by the above method, the test results are recorded in Table 3

[0147] table 3

[0148]

[0149] It can be seen from Table 3:

[0150] 1) the deep blue reactive dye composition of the present invention, compared with the dyestuff represented by general formula (I), its promotion rate is significantly improved;

[0151] 2) The measured value of the promotion rate of the dark blue reactive dye composition of the present invention is much higher than the weighted average value of its constituent dyes, reflecting the effect of compounding and synergizing.

Abstract

The invention provides a dark blue active dye composition and application thereof in dyeing fibers. The dye composition comprises one or more of dye compounds shown in a general formula (1), and one or more of dye compounds shown in a general formula (2). The dark blue active dye composition has excellent dyeing property and various items of dyefastness, and excellent compatibility with other common red and yellow active dyes. Substituent groups in the general formulas (1) and (2) are shown in the specifications.

Description

technical field [0001] The invention relates to a reactive dye composition and its dyeing application on fiber materials, in particular to a dark blue reactive dye composition and its dyeing application on fiber materials. Background technique [0002] The development and research of dark blue reactive dyes has always been one of the hot spots in the dye industry. Not only is blue the most used of all the shades, but it is also a major component of blended black reactive dye compositions or mixtures. [0003] With the increasingly stringent requirements for printing and dyeing fabrics, dark blue reactive dyes must not only have excellent fastness, but also have good application properties, such as dyeing uptake, lifting, color fixation and compatibility. [0004] The blue active dye shown in the general formula (1) of the present invention has a kind of formazan containing copper metal Class (Formazan) dyes. In the late 1980s and early 1990s, major companies published re...
