Abstract
The invention discloses an indigo reduction staining deep dyeing promoter which is a high performance deep dyeing promoter for denim indigo dyeing reduction. The invention is prepared mainly by dispersant, sodium polyacrylate, anionic surfactant, industrial salt, at least one kind of C8-C18 fatty alcohol ethoxylate and at least one kind of rare earth sulfonate. When the deep dyeing promoter is used for indigo dyeing reduction for denim, depth and fastness of the dyeing denim are obviously improved, degree of dyeing is further improved, and using amount of toxic dye indigo and dyeing period are reduced.
Description
One, technical field
The invention belongs to denim dyeing and finishing technique field.
Two, background technology
At present, being applied to denim indigo reduction dyeing high-performance deep-dyeing agent at home mainly is from the imported product in areas such as America and Europe, costs an arm and a leg.Domestic printing and dyeing assistant enterprise does not see as yet can produce and provide this series products.
Three, summary of the invention
The objective of the invention is to provide a kind of high performance indigo reduction deep dyeing promoter, to overcome the defective that present domestic printing and dyeing assistant enterprise fails to produce this series products.
The object of the present invention is achieved like this: indigo reduction deep dyeing promoter of the present invention is mainly by dispersant, Sodium Polyacrylate, anion surfactant, Nacl, at least a C8～C18 fat alcohol ethoxyl compound and composite the forming of at least a rare earth sulfonate.It at first drops into quantitative dispersant, Sodium Polyacrylate and Nacl in the high speed homogenization reactor, adds quantitative pure water, heats up 80～85 ℃, with 3000～4000 rev/mins rotating speed homogeneous 0.5～1 hour; Then, quantitative C8-C18 fat alcohol ethoxyl compound and rare earth sulfonate are dropped in the high speed homogenization reactor, be incubated 80～85 ℃,, be cooled to 50～60 ℃ of dischargings then, make product at last with 100～2000 rev/mins rotating speed homogeneous 1～2 hour.
The present invention is mainly used in indigo reduction dyeing, dyes especially for the denim indigo reduction.The degree of depth and concentration that it can significantly improve denim dyeing further improve its dye uptake, thereby reduce indigo consumption and the dyeing time of toxic dye.Use it can save the materials cost and the technology cost of cowboy's dyeing, improve the class of fabric, improve indigo service efficiency, reduce its consumption.Therefore, independent research is used for denim indigo reduction dyeing high-performance deep-dyeing agent and can be the product that super quality and competitive price are provided in the industry.
Four, the specific embodiment
Indigo reduction deep dyeing promoter of the present invention is the high-performance industry auxiliary agent that a class is mainly used in the dyeing of denim indigo reduction, form through special process is composite by multiple functional surface activating agent and function additive, be a kind of homogeneous aqueous solution of containing certain active ingredient under the normality.It is mainly by dispersant, Sodium Polyacrylate, anion surfactant, Nacl, fat alcohol ethoxyl compound and composite the forming of at least a rare earth sulfonate.Its various components and content are respectively:
Dispersant 5%～70%;
Sodium Polyacrylate 1%～50%
Fat alcohol ethoxyl compound 1%～50%
Anion surfactant 0.2%～80%;
Rare earth sulfonate 0.2%～30%;
Nacl 0.2%～30%
Pure water 10%～90%.
Wherein, dispersant recited above is one or more of dispersant N, dispersant NNO, Dispersant MF or dispersant M series, fat alcohol ethoxyl compound is one or more of C8～C18 fat alcohol ethoxyl compound, Sodium Polyacrylate is a molecular weight at 500～100000 sodium polyacrylate solution or solid polypropylene acid sodium, and anion surfactant then is one or more of sodium alkyl benzene sulfonate, sodium alkyl sulfonate or sodium alkyl sulfate.
And preparation method of the present invention finishes by following steps:
The first step: quantitative dispersant, Sodium Polyacrylate and Nacl are dropped in the high speed homogenization reactor, add quantitative pure water, be warming up to 80～85 ℃, with 3000～4000 rev/mins rotating speed homogeneous 0.5～1 hour;
Second step: quantitative C8～C18 fat alcohol ethoxyl compound, rare earth sulfonate, anion surfactant are dropped in the high speed homogenization reactor, insulation is at 80～85 ℃, with 1000～2000 rev/mins rotating speed homogeneous 1～2 hour, be cooled to 50～6 ℃ of dischargings then, promptly make indigo reduction deep dyeing promoter of the present invention.
When using indigo reduction deep dyeing promoter of the present invention, directly be deployed into dye liquor denim is carried out reduction stain with indigo and other dyeing assistant, and by self functional component, to indigo reduction---oxidation reaction is carried out suitable regulation and control, and promotes the dispersion and the infiltration of dyestuff, thereby significantly improves the degree of depth and the fastness of dyeing, improve dye uptake, give the coloured light of fabric excellence, and can reduce the indigo consumption of toxic dye and shorten dyeing flow, reduce dyeing time.
Embodiments of the invention are:
100 parts of dispersant N, 120 parts of Sodium Polyacrylates, Nacl are dropped into the high speed homogenization reactor for 50 parts, add 500 parts of pure water, be warming up to 80 ℃, with 3000 rev/mins rotating speed homogeneous 1 hour.Then 80 parts in C18 aliphatic alcohol polyethenoxy (15) ether, 50 parts in rare earth sulfonate, neopelex are dropped in the high speed homogenization reactor for 150 parts, insulation is at 80 ℃, with 1000 rev/mins rotating speed homogeneous 2 hours, be cooled to 50 ℃ of dischargings then, promptly obtain indigo reduction deep dyeing promoter.Its product the key technical indexes is as follows:
Outward appearance: sepia transparency liquid;
Solid content: 40 ± 2 (%);
PH value: 7～8 (1% aqueous solution).
Above-described only is preferential embodiment of the present invention.Should be pointed out that to those skilled in the art under the prerequisite that does not break away from the principle of the invention, can also make some improvement, this also is considered as belonging to protection scope of the present invention.
