Abstract
The present invention relates to a kind of alkali-proof active dye, belong to technical field of fine.General reactive dyestuffs are not alkaline-resisting, and dyestuff and alkali can not be present in dye liquor simultaneously, and pad after dye liquor dries so fabric generally adopts, then alkali immerging carries out the dyeing of decatize.These dyeing long flow paths, energy consumption, water consumption is large, and constant product quality is poor.The invention discloses a kind of composition and compound method of alkali-proof active dye, with the reactive dyestuffs alkalescence dye liquor of the method for the invention preparation, after different time is placed, the Color of dyestuff is not affected.Therefore, with alkali-proof active dye of the present invention to textile dyeing, after textile pad dye liquor can be adopted, directly carry out the dyeing of decatize or stacking at room temperature.Adopt alkali-proof active dye of the present invention, effects of energy saving and emission reduction is remarkable, constant product quality.
Description
Technical field
The present invention is a kind of alkali-proof active dye, belongs to technical field of fine.
Background technology
Reactive dyestuffs are the dyestuffs being widely used in cellulose dyeing and stamp at present, and its continuous dyeing at present mainly adopts the dyeing flow process of padding dye liquor → oven dry → alkali immerging → decatize.Due to this process energy consumption, water consumption is high, wastewater discharge large, and the cold pad--batch of Reactive Dyestuff in Recent Years and wet short steaming dyeing obtain the pay attention to day by day of people.Cold pad--batch and wet short steaming dyeing need dyestuff and alkali to be mixed with alkaline aqueous solution, are then applied to fabric by the mode of padding and get on, by bank up or directly decatize makes dyestuff complete fixation reaction.Because common reactive dyestuffs are not alkaline-resisting, when dyestuff and alkaline agent are present in the aqueous solution simultaneously, dyestuff can be hydrolyzed, and causes the degree of fixation of dyestuff to reduce.For vinyl sulfone(RemzaolHuo Xingranliaohuoxingjituan) class reactive dyestuffs, can slough because the sodium sulfovinate salt groups in active group runs into alkali, cause the solubleness of dyestuff to reduce, dyestuff is separated out from dye liquor.Therefore, reactive dyestuffs and alkaline agent are mixed with the stable aqueous solution, reduce the hydrolysis of dyestuff, improve the degree of fixation of dyestuff; Preventing some dyestuff from reducing because running into solubleness after alkali the dyeing defect that causes simultaneously, ensureing cold pad--batch and the wet short one-time success rate steaming dyeing, there is important production application value.
Patent application 200810032831.1 discloses a kind of phthalocyanine reactive dyeing leveling agent, comprise methylene-bis naphthalenesulfonate 10-15%, sulfonated lignin 15-20%, carboxymethyl cellulose 2-5%, urea 25%, solublization is had to dyestuff, dyestuff can be made to add in electrolytical situation and can not separate out, obtain even dyeing effect.Patent application 200910301870.1 discloses a kind of dyeing accelerant of reactive dyestuffs, and its component is organic bronsted lowry acids and bases bronsted lowry, utilizes organic acid and alkali reaction to generate organic salt and promotes reactive dyeing to replace ordinary salt, realize the dyeing of environmental protection low-salt active.200910300953.9 disclose a kind of accelerant for textile dyeing, its main ingredient is rare earth (in rare earth element) 2-5 part, organic phenol halogenide 10-20 part, organic acid 1-10 part, modifier A 1-5 part, levelling agent B1-5 part, can be used in cotton fibre reactive dyeing, reduce the consumption of Sodium sulfate anhydrous.min(99).200810139388.8 disclose a kind of phosphorus-free color fixing alkali, and it consists of sodium metasilicate 20-40 part, crystalline sodium disilicate 5-10 part, Sodium Ethoxide 5-6 part, salt of wormwood 7-9 part, sodium sulfate 10-12 part, chelated dispersants 5 parts, and consumption is Na

31/8-1/10.201010195549.2 accelerants disclosing a kind of reactive dyestuffs, component is amino acid whose sodium salt and sylvite, can realize low-salt active dyeing.Patent ZL200410067188.8 discloses a kind of alkali proof stabilizer for active dye be made up of by a certain percentage alkyl naphthalene sulfonic acid formaldehyde condensation products, naphthalene sulfonic acidformaldehyde condensation product, additive, the alkali stability of dyestuff can be improved after itself and reactive dyestuffs are composite by a certain percentage, prevent dyestuff from condensing and separate out and complete dyeing course smoothly.
Summary of the invention
A kind of alkali-proof active dye of the present invention, be applied in the merchandized handling process of dyestuff, in commercial dye formula, add a certain proportion of alkaline-resisting conditioning agent, be directly mixed with alkali-proof active dye with general mixing equipment, there is application convenient, the features such as alkali stability is good.In alkali-proof active dye of the present invention, the content of alkaline-resisting conditioning agent is 1 ~ 50% of commercial dye quality.
Above-mentioned alkali-proof active dye is mainly used in cold-rolling heap staining and wet short steaming dyeing, has stability at normal temperatures with the alkaline dye liquor of its preparation.Wherein, alkaline-resisting conditioning agent works the ionic equilibrium and the pH value that regulate and control dye base solution, and the dyestuff of precipitation is disperseed rapidly by tensio-active agent.Meanwhile, by the molecular interaction of conditioning agent and dyestuff, the reactivity worth of regulation and control dyestuff, suppresses dyestuff to be alkali catalyzed the tendency of hydrolysis in aqueous, reaches the object extending reactive dyestuffs alkaline aqueous solution storage period.
Alkaline-resisting conditioning agent of the present invention is made up of condenses A and polycarboxylate B.A is the condenses that naphthalene sulfonic salt and formaldehyde are formed according to mol ratio 2: 1, such as naphthalenesulfonate formaldehyde condensation compound, benzyl naphthalenesulfonate formaldehyde condensation compound, 1-methyl naphthalene sulfonic acid salt formaldehyde condensation products, butyl naphthalene sulfonate-naphthalene sulfonate-formaldehyde condenses, propyl naphthalene sulfonate-naphthalene sulfonate-formaldehyde condenses, propyl naphthalene sulfonate-benzene sulfonate-formaldehyde condensation products, the molecular weight of these condensess is 300-700.B is that two kinds of carboxylic acid monomers are polymerized the co-poly carboxylic acid salt obtained according to certain mol ratio.The blending ratio of A and B is that A accounts for 20% ~ 80% of A and B total amount by percentage to the quality.
The general structure of B is as follows:
The molecular weight of above-mentioned polymkeric substance is 3000-80000, and in macromolecular chain, mol ratio p: the q of two kinds of structural units is 7: 3 or 4: 6 or 5: 5.
