Problems solved by technology

[0019] However, practice shows that, as commercial dyes, the improvement rate and color fixation rate of bicyclic formazan reactive dyes are not ideal yet.
Co-dye with commonly used red and yellow reactive dyes, compatibility needs to be further improved

Embodiment 1

[0119] Shade of navy blue reactive dye composition of the present invention

[0120] The color and luster of the dye represented by the general formula (I) is sky blue and relatively light, and cannot be used as the blue component of the three primary colors, and the color and luster of the dye represented by the general formula (II) is dark navy blue.

[0121] 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

[0123] Lift rate test (K / S value at absorption wavelength 620nm)

[0124] Measure the lifting rate of the following dyes according to the above method, and the test results are recorded in Table 2

[0125] Table 2

[0126]

[0127]

[0128] It can be seen from Table 2:

[0129] 1) navy blue reactive dye composition of the present invention, compared with the dyestuff represented by general formula (I), its promotion rate is significantly improved;

[0130] 2) The measured value of the promotion rate of the navy 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.

Embodiment 3

[0132] Determination of initial dyeing rate and exhaustion rate

[0133] Measure the initial dyeing rate and exhausted dyeing rate of the following dyestuffs according to the above method, and the test results are recorded in Table 3

[0134] table 3

[0135]

[0136]

[0137] It can be seen from Table 3:

[0138] 1) the initial dyeing rate of navy blue reactive dye composition of the present invention is compared with the dyestuff represented by general formula (1), all improves to some extent, has reduced the initial dyeing rate of general formula (1) expression, has avoided dyestuff to be dyed too much The rapid color flower phenomenon improves the level dyeing property and shows good compatibility with the conventional three primary colors yellow and red dyes when co-dyeing;

[0139] 2) The navy blue reactive dye composition of the present invention still maintains a higher exhaustion rate.

Abstract

The invention provides a navy reactive dye composition and dying application thereof. The dye composition comprises one or more dye compositions expressed by a formula (1) shown as the specification and one or more dye compositions expressed by a formula (2) shown as the specification, which are mixed at a certain ratio. Compared with the dyes expressed by the formula (1), the navy reactive dye composition provided by the invention has obviously improvement in fixation, leveling property, compatibility and upgrade rate. Surprise is that the navy reactive dye composition provided by the invention can still maintain the good color fastness of the dyes expressed by the formula (1). The navy reactive dye composition provided by the invention has the advantages of excellent dyeing property and various color fastness, and excellent compatibility when in co-dyeing with other common red and yellow active dyes. FORMULA (1) and FORMULA (2).

Description

technical field [0001] The invention relates to a reactive dye composition and its dyeing application on fiber materials. Specifically, the invention relates to a navy blue reactive dye composition and its dyeing application on fiber materials. Background technique [0002] The invention relates to a navy blue reactive dye composition, which significantly improves and enhances its dyeing application performance and color fastness through compounding and synergizing. [0003] One of the components of the navy blue reactive dye composition of the present invention is a formazan dye containing copper metal. [0004] In 1986, Hoechst Company published the patent US4607098, which disclosed the formazan type reactive dye with the following structure and its synthesis method. [0005] [0006] dye m [0007] This dye structure is different from the structure of the formazan reactive dye disclosed in the patent US4336190 published by Hoechst in 1982. [0008] [0009] dye n...
