Abstract
The invention relates to an alkali-proof active dye and belongs to the technical field of fine chemistry. Common active dyes are susceptible to alkali and cannot exist in dye solution with alkalis, so textiles are usually dyed by a process of first padding with dye solution, drying, padding with alkaline solution and steaming; however, this dyeing process is long in flow, high in energy and water consumption and low in product quality stability. The invention discloses the composition and preparation method of the alkali-proof active dye. After the alkaline dye solution of the active dye prepared by the method is stood for different time periods, the dyeing effect of the dye is not affected. Therefore, when the alkali-proof active dye is used for dyeing textiles, a dyeing process of first padding the textiles with dye solution and then directly steaming or stacking at room temperature can be adopted. When the alkali-proof active dye provided by the invention is used, the energy-conservation and emission reduction effect is obvious, and the product quality is stably.
Description
Technical field
The present invention is a kind of alkaline-resisting reactive dyestuffs, belongs to the fine chemical technology field.
Background technology
Reactive dyestuffs are the dyestuffs that are widely used in cellulose dyeing and stamp at present, and the dyeing flow process of padding dye liquor → oven dry → alkali immerging → decatize is mainly adopted in its continuous dyeing at present.Because this process energy consumption, water consume height, wastewater discharge is big, the cold rolling heap of reactive dyestuffs and wet weak point steam the pay attention to day by day that dyeing obtains people in recent years.Cold rolling heap and wet short steam dyeing and dyestuff and alkali need be mixed with alkaline aqueous solution is applied to fabric by the mode of padding then and gets on, by bank up or directly decatize make dyestuff finish the fixation reaction.Because common reactive dyestuffs are not alkaline-resisting, when dyestuff and alkaline agent were present in the aqueous solution simultaneously, hydrolysis can take place in dyestuff, causes the degree of fixation of dyestuff to reduce.For vinyl sulfone(Remzaol class reactive dyestuffs, because running into alkali, can slough the sodium sulfovinate salt group in the active group, 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; Prevent some dyestuff simultaneously because of solubleness after running into alkali reduces the dyeing defect that causes, guarantee cold rolling heap and the wet short painted one-time success rate that steams, have important production application and be worth.

31/8-1/10.201010195549.2 disclose a kind of accelerant 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 of being made up of by a certain percentage alkyl naphthalene sulfonic acid formaldehyde condensation products, naphthalene sulfonic acidformaldehyde condensation product, additive, itself and reactive dyestuffs can be improved the alkaline-resisting stability of dyestuff after composite by a certain percentage, prevent that the dyestuff cohesion from separating out and finish dyeing course smoothly.
Summary of the invention
A kind of alkaline-resisting reactive dyestuffs of the present invention, be applied in the commercialization production process of dyestuff, in the commercial dye prescription, add a certain proportion of alkaline-resisting conditioning agent, directly be mixed with alkaline-resisting reactive dyestuffs with general mixing equipment, have and use conveniently characteristics such as alkaline-resisting good stability.The content of alkaline-resisting conditioning agent is 1～50% of commercial dye quality in the alkaline-resisting reactive dyestuffs of the present invention.
Above-mentioned alkaline-resisting reactive dyestuffs are mainly used in cold-rolling heap staining and the wet short dyeing that steams, and the alkaline dye liquor of preparing with its has stability at normal temperatures.Wherein, alkaline-resisting conditioning agent plays the ionic equilibrium and the pH value of regulation and control dyestuff basic solution, and the dyestuff of separating out can be disperseed rapidly by tensio-active agent.Simultaneously, by the molecular interaction of conditioning agent and dyestuff, the reactivity worth of regulation and control dyestuff, the inhibition dyestuff by the tendency of alkali catalyzed hydrolysis, reaches the prolongation reactive dyestuffs alkaline aqueous solution purpose of storage period in the aqueous solution.
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 form according to mol ratio at 2: 1, for example naphthalenesulfonate formaldehyde condensation compound, benzyl naphthalenesulfonate formaldehyde condensation compound, 1-methyl naphthalene sulfonic acid salt formaldehyde condensation products, butyl naphthalene sulfonate-naphthalenesulfonate-formaldehyde condensation products, propyl naphthalene sulfonate-naphthalenesulfonate-formaldehyde condensation products, propyl naphthalene sulfonate-benzene sulfonate-formaldehyde condensation products, the molecular weight of these condensess is 300-700.B is the co-poly carboxylic acid salt that two kinds of carboxylic acid monomers obtain according to the certain molar ratio polymerization.The blending ratio of A and B be by percentage to the quality A account for A and B total amount 20%～80%.
The general structure of B is as follows:
The molecular weight of above-mentioned polymkeric substance is 3000-80000, and the mol ratio p of two kinds of structural units: q is 7: 3 or 4: 6 or 5: 5 in the macromolecular chain.
