Abstract
A preparation method of functional woad belongs to the preparation technical field of woad which is a fine chemical vat dye. The functional woad comprises the components of woad filter mass, dispersant, deep-dyeing agent and industrial salt, and all of the components are respectively calculated by weight percentage of the woad filter mass as follows: 1-25 percent of the dispersant, 1-18 percent of the deep-dyeing agent and 1-23 percent of the industrial salt. The deep-dyeing agent is naphtholsulfonic acid formaldehyde condensation product and/or fatty alcohol polyethenoxy, wherein the condensation degree of the naphtholsulfonic acid formaldehyde condensation product is 5-8, and the epoxy number of the fatty alcohol polyethenoxy is 25-35. Aiming at the characteristics of the woad, the invention effectively improves the degree of dyeing, the degree of exhaustion, the tinctorial yield and the fixation ratio of the woad product on cotton fabric and blended fabric through further adding the deep-dyeing agent and the industrial salt and reasonably proportioning all components based on the preparation of the woad by singly adding the dispersant, and reduces the emission of pollutant in dye wastewater.
Description
Technical field
The present invention relates to a kind of preparation method of functional woad, belong to the indigo preparing technical field of fine chemistry industry vat dyes.
Background technology
Bipseudoindoxyl dye is water-fast polycyclc aromatic compound, the essential characteristic of their molecular structures is, in the two key systems of molecular conjugation, contain two carbonyls, and the carbon atom of carbonyl must be the carbon atom in the aromatic ring, carbonyl acts on mutually and is reduced with vat powder in basic solution, changes hydroxyl into, the oxy-compound vat acid, and become water-soluble substance sodium salt, i.e. leuco compound gone back.
The dyeing course of bipseudoindoxyl dye is through reduction and two chemical reactions of oxidation, is adsorbed on leuco compound on the fiber during dyeing through the oxidation of air or other oxygenants, transfers insoluble vat dyes again to and anchors on the fiber, thereby make fiber catch color.Indigo water insoluble, pure, ether and benzene; All dissolvings hardly in diluted acid or dilute alkaline soln, but dissolve in the vitriol oil, also be dissolved in ebullient phenol, oil of mirbane or the aniline.290 ℃ of distillations.390～392 ℃ of decomposition.
Indigoly compare with other vat dyes, color is darker, and lower to the avidity of fiber, can not once dye heavy colour.Indigo sublimation fastness is low, and its coloured fibre should not press.Traditional indigoly be divided into two kinds, a kind of is that the indigo direct oven dry after cleaning is obtained indigo filter cake, and another kind is with the indigo adding dispersion agent after cleaning, and pulls an oar into indigo slurry, spray-dried and wetting properties particulate state or powdery are indigo.But it is low that the indigo ubiquity of these method preparations dye uptake, the not high situation of dye utilization rate.
Summary of the invention
It is reasonable to the purpose of this invention is to provide a kind of formulating of recipe, can effectively improve dyeing behavior, reduces the preparation method of the functional woad of production cost and environmental pollution.
The present invention is a kind of preparation method of functional woad, comprises indigo filter cake, dispersion agent, it is characterized in that also comprising simultaneously hyperchromicity agent and Industrial Salt, the composition of each component is respectively with the weight percent meter of indigo filter cake: dispersion agent 1%～25%, hyperchromicity agent 1～18%, Industrial Salt 1～23%.
Described hyperchromicity agent can be sulfonaphthol formaldehyde condensation products and/or fatty alcohol-polyoxyethylene ether, and the condensation degree of its sulfonaphthol formaldehyde condensation products is 5～8, and the epoxy number of fatty alcohol-polyoxyethylene ether is 25～35.
Described dispersion agent can be condensation compound of methyl naphthalene sulfonic acid and formaldehyde (Dispersant MF), naphthalene sulfonic acidformaldehyde condensation product (dispersing agent NNO), benzyl naphthalene sulfonic formaldehyde condensation compound (dispersing agent CNF), the mixture of any one or more of sodium lignosulfonate (xylogen 85A, 83A) etc.
The addition of described dispersion agent can be preferably 1%～15%.The addition of described hyperchromicity agent can be preferably 1～12%.The addition of described Industrial Salt can be preferably 1～16%.
The present invention is directed to indigo characteristic, prepare on the indigo basis at former single interpolation dispersion agent, compare through optimization design and test of many times, by further interpolation hyperchromicity agent and Industrial Salt, and each component carried out rational proportion, effectively improved the dye uptake of indigo finished product on cotton fabric and BLENDED FABRIC thereof on the one hand, degree of exhaustion, tinctorial yield, degree of fixation, increase the avidity of bipseudoindoxyl dye to fiber, increase indigo intensity and fastness, can effectively reduce consumption indigo when dyeing, reduce indigo production cost, reduced the quantity discharged of pollutent in the dyeing waste water on the other hand, reduce the difficulty of indigo treatment of dyeing wastewater and to the pollution of environment, economic benefit and environmental benefit are fairly obvious.
Embodiment
