Embodiment 1

[0110] Lift rate test (K / S value at absorption wavelength 600nm)

[0111] Measure the promotion rate of following dyestuff according to above-mentioned embodiment measuring method, test result is recorded in table 2

[0112] Table 2

[0113]

[0114] It can be seen from Table 2:

[0115] The black dye composition of the present invention has good lifting performance, and a satisfactory dyeing depth can be achieved by using a small amount; at the same time, the dyeing depth of viscose and nylon fibers is close, and the synchronous lifting performance is good.

Embodiment 2

[0117] Dye exhaustion rate and color fixation rate test (absorption wavelength 600nm)

[0118] Determination of exhaustion rate and color fixation rate of following dyestuffs according to above-mentioned embodiment measuring method, test result is recorded in table 3

[0119] table 3

[0120] dye Exhaustion rate (%) Fixation rate (%) Dye Composition A 88.4 82.7 Dye composition B 90.2 83.9 Dye composition C 89.5 83.0 Dye composition D 88.1 81.8

[0121] It can be seen from Table 3:

[0122] The black dye composition of the present invention has higher dyeing exhaustion rate and color fixing rate, and the color fixing rate and the dyeing exhaustion rate are relatively close. This shows that the dye utilization rate is very high, the floating color is easy to remove, the actual production washing process is reduced, and the discharge of dyeing sewage in production can be greatly reduced.

Embodiment 3

[0124] Same color test

[0125] Measure the homochromaticity of following dyestuff according to above-mentioned embodiment measuring method, test result is recorded in table 4

[0126] Table 4

[0127]

[0128]

[0129] It can be seen from Table 4:

[0130] Compared with reference dye X and reference dye Y, the black dye composition of the present invention has similar apparent depth on both surfaces of nylon and viscose, and smaller color difference value. Excellent homochromaticity when dyeing brocade and viscose roman cloth, and can achieve excellent level dyeing effect.

Abstract

The invention provides a black dye composition and dyeing application and method thereof. The black dye composition and the dyeing application and method thereof are used for dyeing of brocade / cotton and brocade / viscose blended fabrics and interlacing fabrics through the one-bath and two-step method. The composition comprises one or more reactive dye compounds shown in the general formula (I), one or more reactive dye compounds shown in the general formula (II) and one or more 1:2 metal complex dye compounds shown in the general formula (III), wherein the dye compounds are mixed in a certain proportion. Fastnesses, especially light fastness and wet treatment fastness, of the dye composition are excellent, and the dye composition can be widely used in coloring of cellulose fibers, polyamide fibers, protein fibers, blended textiles and the like. The dye composition has an unexpected coloring effect during union dyeing of brocade / cotton and brocade / viscose blended fabrics and interlacing fabrics by means of the one-bath and two-step method. Please see the formulas in the description.

Description

technical field [0001] The invention relates to a dye composition and its dyeing application and method. Specifically, the present invention relates to a dye composition for one-bath two-step dyeing of nylon / cotton, nylon / viscose blended and interwoven fabrics, as well as its dyeing application and method. Background technique [0002] Nylon / cotton, nylon / viscose blended and interwoven fabrics combine the excellent properties of nylon fiber and cellulose fiber to a certain extent, not only have good moisture absorption and breathability of cellulose fiber, but also have good elasticity and excellent abrasion resistance of nylon . Nylon / cotton, nylon / viscose blended and interwoven fabrics feel plump, smooth, comfortable to wear, elastic and glossy, and are currently very popular clothing fabrics. [0003] Nylon fibers and cellulose fibers have different internal molecular structures, resulting in different dyeing properties, which brings certain difficulties to the dyeing p...
