Embodiment 1
[0069] The following dye compositions are provided:
[0076] Dissolve the above dye composition in 1000 parts of water, add 20 parts of Glauber's salt and 100 parts of non-mercerized cotton cloth, stir the dyeing solution from room temperature for 30 minutes to reach 60°C, then add 10 parts of soda ash, and continue to maintain 60°C for dyeing 1 Hour. During the dyeing process, samples were taken regularly, and the fabric showed the same gray tone, showing excellent compatibility; after dyeing, it was washed, soaped and dried to obtain a light gray fabric with excellent level dyeing property.
Embodiment 2
[0078] The following dye compositions are provided:
[0079] red reactive dye
[0080] 0.2 parts of the dyestuff of formula (3)
[0081] yellow reactive dye
[0082] C.I. Reactive Yellow 176 0.2 parts
[0083] blue reactive dye
[0084] C.I. Reactive Blue 221 0.28 parts
[0085] Dissolve the above dye composition in 1000 parts of water, add 30 parts of Glauber's salt and 100 parts of non-mercerized cotton cloth, keep the dyeing solution at 60°C for 30 minutes, then add 15 parts of soda ash, and continue to maintain 60°C for 1 hour of dyeing. When finished, it is washed, soaped and dried to obtain a light brown fabric. Repeat the dyeing process many times, and the ΔC and ΔH of the obtained fabrics are all within 0.5 compared with each other, showing a high degree of presentability, and the one-time color matching rate is higher than 90%.
Embodiment 3
[0087] The following dye compositions are provided:
[0088] red reactive dye
[0089] 0.2 parts of the dyestuff of formula (2)
[0090] yellow reactive dye
[0091] C.I. Reactive Yellow 145 0.2 parts
[0092] blue reactive dye
[0093] C.I. Reactive Blue 194 0.28 parts
[0094] Dissolve the above dye composition in 1000 parts of water, add 30 parts of Glauber's salt and 100 parts of non-mercerized cotton cloth, stir the dyeing solution from room temperature for 30 minutes to reach 60°C, then add 15 parts of soda ash, and continue to maintain 60°C for dyeing 1 Hours, after dyeing, washing, soaping and drying, the dye composition has a high fixation rate, the unfixed part is easy to wash with water, and the wet fastness is good. The obtained fabric has excellent reproducibility, level dyeing and one-time color matching.

Description
technical field [0001] The present invention relates to a reactive dye composition suitable for dyeingcellulosefiber and materials containing cellulosefiber and its application, especially a reactive red dye composition containing amide groups and its application. Background technique [0002] Reactive dyes are often used for dyeingcellulose fibers such as cotton yarn and rayon. It is well known that in the dyeing of cellulose fiber materials using reactive dyes, it is useful to use red, yellow, and blue reactive dyes as dyes for three primary colors, and to add them in various ratios for dyeing. [0003] Although the development of the application of reactive dyes today is towards the requirement of one-time dyeing and finishing, when the affinity, reactivity, dyeing speed or temperature dependence of the dyes used as the dyes for the three primary colors are different, There are problems such as the so-called uniformity of dyeing caused by uneven dyeing in the middle ...
