Abstract
The invention provides a reactive dye compound and a dyeing method. The compound is provided with dyeingcellulosefiber or fiber material containing cellulose which has good reproducibility, leveling property and color fastness, and has hydrophilicity and well reactivity of dyeing in balance. The reactive dye compound of the invention comprises a blue reactive dye compound of a blue reactive dye shown in a general formula (A) containing a free acid form and a blue reactive dye shown in a general formula (1), and a reactive dye compound containing the blue reactive dye compound, a special red reactive dye and / or a yellow reactive dye. The invention also provides a dyeing method using the cellulosefiber or the fiber material of the compound; in the formula, R represents a hydrogen atom, a halogenous atom or a C1-C4 alkoxyl radical; ml represents an integer form 0 to 2, R1 and R2 respectively and independently represent a hydrogen atom or an alkyl radical which can be substituted; Xl represents a halogenous atom; Y1 represents that -SO2CH is equal to CH2 or SO2CH2CH2Z1 (Z1 represents a radical which breaks away due to the alkaline effect).
Description
technical field [0001] The present invention relates to a reactive dye composition suitable for dyeing cellulose fibers or materials containing cellulose fibers and a dyeing process using the composition. Background technique [0002] Reactive dyes are mostly used in the dyeing of cellulose fibers such as cotton and rayon. It is well known that in the dyeing of cellulose fibers using reactive dyes, it is useful to use yellow, red and blue reactive dyes as dyes for the three primary colors and mix them in various ratios for dyeing. [0003] However, when the affinity, reactivity, dyeing speed, and temperature dependence of each dye used as the dye of the three primary colors are different, there are problems with uniform dyeing such as dyeing spots during dyeing, and color differences between dyeing batches. and other issues such as dyeing reproducibility. With regard to level dyeing and dyeing reproducibility, in recent years, with the diversification of the types and form...
