Embodiment

[0027] Several formulas were screened out based on superior application performance and other characteristics, and the specific ratios are shown in Table 1.

[0028] Table 1

[0029]

[0030]

[0031] Each reactive dye composition in the above-mentioned Table 1 is carried out dry powder mixing in the mixing tank, or spray drying after dissolving together. There are other reactive dye compositions that are not listed one by one, but are included in the present invention.

Embodiment 2

[0032] Embodiment 2: 100g cotton cloth, the composite type reactive blue dye composition that obtains by embodiment 1, by the weight 2% of fabric, in the dyeing bath that contains 60g / l sodium sulfate, bath ratio is 20:1, 60 ℃ Absorb for 30 minutes, add soda ash (amount of 15-20g / l) to fix the color for 45 minutes. The dyed fabric is washed, soaped and dried. The obtained dyed cotton cloth has uniform color and satisfactory light and wet treatment fastness. The specific performance is shown in Table 2.

[0033] Table 2

[0034]

[0035]

[0036] According to a large number of experimental detections, the composite reactive blue dye of the present invention has better application performance than the traditional brilliant blue dye, and the specific comparative data are shown in Table 3.

Abstract

The invention belongs to the field of dyes and relates to an active dye composite product suitable for dyeing cellulose fibers or cellulose-containing fibers and particularly relates to a composite active blue dye. The composite active blue dye is prepared by compounding 10-90 parts by weight of a dye A represented by a formula (1), 10-90 parts by weight of a dye B represented by a formula (2) and 0-100 parts by weight of an additive. By the composite active blue dye, the medium-temperature coloring can be performed on the cellulose fibers, during the dyeing, the advantages of alkali resistance, good leveling, good even-dyeing property, good synchronization and color reproducibility and difficulty in uneven dyeing are achieved, and the colored fibers have not only a unique brilliant blue-green color and but also very good light fastness, rubbing fastness, water-washing fastness, sweat fastness and the like. The composite active blue dye can exhibit good application performance and fills the defects of commercially available other active brilliant blue.

Description

technical field [0001] The invention belongs to the field of dyes, and relates to a reactive dye composite product suitable for dyeing cellulose fiber or cellulose-containing fiber, in particular to a composite reactive blue dye. Background technique [0002] With the continuous development of cellulose fiber varieties and the continuous development of dyeing technology, when using reactive dyes to color cellulose fibers, higher and higher requirements are put forward for the application performance of reactive dyes. Due to the coloring of cellulose fibers by single-color dyes, the comprehensive value of various performance indicators is difficult to achieve satisfactory results. For example, reactive blue 19 is an anthraquinone-type monovinylsulfone-based active group. When it is coloring cellulose fibers, It is very prone to poor alkali resistance, and it is very easy to dye flowers when dyeing. Reactive Blue 198 is a triphenyldioxazine type containing two monochloro-s-tr...
