M " is H or K or Na;
Can be preferably any one or more than one dye monomer suc as formula the Compound C shown in (3) general structure suc as formula (10)~(12):
Surplus is an auxiliary agent.
A kind of active composite dye comprises following component by weight percentage:
5.0 the Compound C as the formula (3) of~60.6% compd A as the formula (1), 5.0~40.0% compd B as the formula (2) and 15.0~90.1%, surplus is an auxiliary agent.
Auxiliary agent described in the present invention is the commonly used salt (main component be NaCl) of reactive dyestuffs when composite, (main component is Na to Sodium sulfate anhydrous.min(99)
2SO
4), dispersion agent, diffusant and tensio-active agent or other stablizer etc.
The weight percentage of described compd A is preferably 15~49.6%; The weight percentage of compd B is preferably 8.1~25.5%; The weight percentage of Compound C is preferably 26.5~75.5%.
A kind of active composite dye of the present invention can prepare in order to the below method:
After the dyestuff of above-mentioned weight ratio and auxiliary agent, water mixing and stirring, oven dry or spraying drying in drying room.Above-mentioned compd A, compd B, Compound C also can adopt commercially available prod reactive golden yellow R-NN, and active carbuncle R-NN, reactive navy blue R-NN do to piece together and mix.
Three components of the present invention are tetrazo, dual-active (double active base is two ethene sulfuryls), middle warm type, oiliness and the water-based ratio is very near, on to dye curve very approaching, they are to the avidity of fiber, dye uptake, degree of fixation, to salt, to the susceptibility of alkali, to the influence of bath raio and all more approaching to the susceptibility of temperature, good dyeing synchronism and level-dyeing property are arranged between the composition, and higher degree of fixation is arranged, be applicable to the dyeing of Mierocrystalline cellulose or thiozell.
Compd A described in the present invention, B, C all meet environmental protection and the ecological requirement of the Oeko-Tex Standard of the European Community 100, solved effectively with red, yellow, the blue reactive dyestuffs of common double active group (containing a chloro-s-triazine and vinyl sulfone double-active base) and pieced together this problem that easily produces look flower and poor reproducibility when dying coffee color, black, make dyeing quality obtain more effective guarantee, have that lifting force is good, a premium properties such as good level-dyeing property, dyeing repeatability and dye uptake height.
Embodiment
The invention will be further described below in conjunction with embodiment and Comparative Examples, but protection scope of the present invention is not limited to this.
