Or, described active red dye composition is by component A, B component, and component C and/or component D composition, component A based on described and B component, component A quality percentage composition is 20%~80%, and B component quality percentage composition is that quality percentage composition is 20%~80%, and component C and/or component D quality are not more than 40% (being preferably 5%~30%) of component A and B component quality sum; Described component A be compound (I-1), (I-3) and (I-7) in one or more, described B component is compound (II-1), described component C is compound (III-1), and described component D is compound (IV-2).
The dye composition of formula of the present invention (I)~formula (IV), can free acid (M
1~M
4for-H) or salt (M
1~M
4for alkali metal atom) form exist, preferably exist with the form of salt, described salt is preferably sodium salt (M
1~M

Active red dye composition of the present invention, component A, B component, component C and the component D using can be synthetic by mode well known to those skilled in the art easily, as prepared according to the method described in patent US5359040, US4341699, JP60023453 and CN1447840 or similar method.
Red reactive dye composition of the present invention, its preparation method comprises formula (I)~formula (IV) dyestuff is mixed according to aforementioned proportioning, mixing can adopt conventional mechanical system to carry out, as at shredder, in kneader or clarifixator, carry out, in mixing process, single dyestuff (I), (II), (III) and (IV) can powdery, granular, the aqueous solution or resulting solution form exist, as single dyestuff (I), (II), (III) during and (IV) with the form blending of resulting solution, separating red reactive dyes mixture of the present invention from resulting solution can be undertaken by general known method, for example use ionogen (as sodium-chlor or Repone K) from reaction medium, dyestuff to be saltoutd and leached, or mixing solutions is evaporated, spraying is dry.
Active red dye composition of the present invention also can contain the coloration additive of various conventional uses in dyeing and dye formulations, its consumption can be selected according to actual needs, and additive and dyestuff weight ratio are (10~90) conventionally: (10~90).Described additive is electrolyte salt sodium sulfate, pH adjusting agent SODIUM PHOSPHATE, MONOBASIC, dust-proofing agent, solubility promoter, dispersion agent etc. such as.
Active red dye composition of the present invention, is specially adapted to the dyeing of cellulosic fibre material, as the printing and dyeing of cotton, fiber crops, regenerated fibre and yarn fabric thereof, in addition, is also applicable to the dyeing of tynex, protein fibre and yarn fabric thereof.Dyeing process can carry out according to known, usual dip-dye, pad dyeing and printing method.
Dip method is to adopt the electrolytic salt (as sodium sulfate, sodium-chlor) of knowing and the acid binding agent (as sodium carbonate, sodium hydroxide) of knowing to be used alone or as a mixture.Can once or in batches add in dye bath according to ordinary method.Also can further add dyeing auxiliaries (as levelling agent, retarding agent) etc., dyeing temperature is generally 40~90 ℃, and preferably dyeing temperature is 50~70 ℃, and dye bath ratio is generally 1: 5~50 (pollutants: staining fluid).
Pad dyeing rule, as cold-rolling heap staining method, makes the material of wish dyeing, utilizes neutral salt and acid binding agent (as water glass, sodium hydroxide) pad dyeing, then at room temperature banks up and dyes for 6~20 hours.Continuous one bathes pad dyeing method, is to mix with the acid binding agent of knowing and padding liquor, makes fabric carry out pad dyeing, then dry or vapour steaming colour fixing according to ordinary method; Two bathe pad dyeing methods be first with dyestuff to fabric pad dyeing, then with inorganic neutral salt and the acid binding agent known, dyeing and weaving thing is processed, dye fabric drying or vapour steaming colour fixing according to ordinary method by what processed.
Textile printing method, as single-phase Decal, to stick with paste containing the stamp of knowing acid binding agent, is imprinted on fabric, and with being dried or vapour steaming colour fixing; Two-phase stamp comprises stamp stick with paste and be imprinted on fabric after, immerse high temperature (90 ℃ or more than) containing fixation in the solution of inorganic neutral salt and acid binding agent.
Active red dye composition of the present invention, compatibleness is good, and enhancing is good, and solubleness and degree of fixation are high, and easily washing property is good, can obtain dark heavy colour and adjust while being applied to the printing and dyeing of the materials such as cellulosic fibre.
