Embodiment 1

[0102] The dye A and the dye B of the present invention are used for pad dyeing, and the color of the dyed fabric is bright golden yellow. Measured according to relevant international standards, the staining fastness of dyed fabrics is 4 grades, the color change is 4-5 grades, the dry rubbing fastness is 4 grades, the wet rubbing fastness is 3-4 grades, and the color fastness to perspiration (alkali sweat) is 4 grades. Grade 4, color fastness to perspiration (acid sweat) grade 4.

[0103] The dye A and the dye B of the present invention are used for exhaust dyeing, and the color of the dyed fabric is bright golden yellow. Measured according to relevant international standards, the staining fastness of dyed fabrics is 4 grades, the color change is 4-5 grades, the dry rubbing fastness is 4 grades, the wet rubbing fastness is 3-4 grades, and the color fastness to perspiration (alkali sweat) is 4 grades. Grade 4, color fastness to perspiration (acid sweat) grade 4.

Embodiment 2

[0109] Example 2 Resistance to photochromism

[0110] For yellow reactive dyes, its photochromic resistance is particularly important. The color measurement data are listed in Table 2, Table 3, Table 4, and Table 5 (dyeing depth: 4% o.w.f. depth).

[0111] Table 2

[0112] DE Dye C Dyeing Fabric Unlit 0 Dye C dyed fabric light for 8 hours 0.73 Dyed fabric dyed with dye C for 8 hours after exposure to light for 8 hours 1.09

example 3

[0122] Example 3 color fixing rate

[0123] The color fixation rate is the percentage by weight of the dyes that are finally absorbed by the fabric in the total amount of dyes.

[0124] The determination of color fixation rate is listed in Table 6 and Table 7.

[0125] Table 6

[0126]

[0127] Table 7

[0128]

[0129] It can be seen from Table 6 and Table 7 that the color fixation rate of the yellow reactive dye composition of the present invention is higher than that of a single dye.

Abstract

The invention provides a yellow active dye composition. The composition comprises one or a plurality of known yellow active dyes I and active dyes II mixed according to a certain proportion. The yellow active dye composition has the advantages of fresh golden color and excellent fastness; compared with the component dyes of the combination, the composition is remarkably improved in relative dyeing depth, dye-fixing percentage, dye uptake and increase rate; and amazingly, the photochromic resistance of the composition is also obviously improved.

Description

technical field [0001] The invention relates to a reactive dye composition and its dyeing application on fiber materials, in particular to a yellow reactive dye composition and its dyeing application on fiber materials. Background technique [0002] Reactive dyes are known for their bright color, complete chromatogram, easy application, low cost and excellent fastness. Reactive dyes have become the most important dye category for the dyeing of cellulosic fiber textiles. [0003] The development and research of yellow reactive dyes has always been one of the hot spots in the dye industry. [0004] C.I.Reactive Yellow 145 is the representative variety widely used in the current yellow reactive dyes. [0005] Its structural formula is: [0006] [0007] This dye has good color fastness, but it also has certain defects, such as relative dyeing depth, lifting property and level dyeing property, which are difficult to meet the current printing and dyeing requirements.
