Abstract
This invention is a productive method of printing paste, it is a complex starch its viscosity is adjustable. It contains: Carboxymethylated starch, and inter-connected carboxymethylated starch, and complex them to produce it. This complex starch is a complex denaturation starch use to reactive dyes, its adjustable viscosity range may be expanded, be useful to printing and starching.
Description
Technical field
The preparation method and the application of the composite converted starch printing gum that a kind of viscosity is adjustable, this printing gum are the composite modified starchs that a kind of carboxymethyl starch and crosslinked-carboxymethyl starch complex obtain, and belong to technical field of modified starch.
Background technology
Printing gum is a kind of macromolecular compound that plays thickening power in print paste, general equal energy water-soluble or in water fully swelling, dispersion and form the colloidal solution of stiff.It determines the fineness of stamp behavior in service, dyestuff surface tinctorial yield, pattern profile etc. as the main component of print paste.Printing gum commonly used has sodium alginate, imperial glue, gum Arabic etc., but price is more expensive.Therefore seeking close, the moderate product of a kind of performance, is very necessary.
Carboxymethyl starch is a kind of water soluble anion type starch product, substitution value is big, on the starch polymer the negative charge of being with many, because static repels intermolecular generation, stretching, extension can both contact each carboxyl fully with hydrone in water, and produces attraction, thereby the thickener water-retaining property is strengthened, water-soluble increase, and soluble in water, can be used for the cotton fabric printing dyestuff by the instead of part sodium alginate.Sodium alginate and carboxymethyl starch are dissimilar fluids, and sodium alginate is a Newton type fluid, and anti-dilution property is good, carboxymethyl starch is a pseudoplastic fluid, viscosity changes greatly during dilution, wayward when using needed viscosity, give and bring certain trouble when using.
Summary of the invention
The object of the present invention is to provide a kind of etherificate converted starch and crosslinked-etherificate converted starch to carry out preparation method and application thereof composite and the composite modified starch that obtains.Obtain single carboxymethyl starch with the chloroacetic acid reaction by starch in alcoholic solution and under the alkali condition earlier, undertaken under alkali condition, obtaining crosslinked-etherificate converted starch after the cross-linking reaction by crosslinking agent and starch again with chloroacetic acid, two kinds of converted starches are according to the requirement of the different clothes of textile printing and dyeing, carry out the composite of different proportion, the printing paste with active dye that can regulate as a kind of viscosity.
Technical scheme of the present invention: a kind of preparation method of composite converted starch printing gum be with a kind of carboxymethyl starch and a kind of crosslinked-carboxymethyl modified starch is composite and make, and makes it have etherificate simultaneously, the characteristic of crosslinked-etherification starch.
The synthetic method of described carboxymethyl starch, be to be raw material with starch, with ethanol is reaction medium, be deployed into mass percentage concentration and be 30～50% starch emulsion, add chloroacetic acid, use adjusting PH with base, react under alkali condition, reactant makes carboxymethyl starch through washing, dehydration, drying.
Described crosslinked-preparation method of carboxymethyl starch, be to be raw material with starch, with ethanol is reaction medium, be mixed with mass percentage concentration and be 30～50% starch emulsion, disposable adding crosslinking agent and chloroacetic acid, use adjusting PH with base, react under alkali condition, reactant makes crosslinked-carboxymethyl starch through washing, dehydration, drying.
The composite of described two kinds of converted starches is meant according to the different requirements of printing gum to sticking with paste, and changes the relative scale of two kinds of starch.Carboxymethyl starch: crosslinked-carboxymethyl starch complex mass percent is 20～80%: 80～20%.
The used etherifying agent of etherificate sex change can be chloroacetic acid etc.
The used crosslinking agent of crosslinked sex change can be epoxychloropropane, formaldehyde, phosphorus oxychloride, sodium trimetaphosphate etc.
The process conditions of key reaction etherification reaction and crosslinked-etherification reaction are: the reaction time was controlled between 1～4 hour, reaction temperature is controlled between 25～50 ℃, the pH value is controlled between 8.5～13.0, add chemical reagent and all under agitation carry out with reaction, reactant gets product through ethanol washing, Water Extraction Machinery dehydration, pneumatic conveying drying.
The application of described composite converted starch is mainly used in the printing gum that REACTIVE DYES is gone up in weaving.
Beneficial effect of the present invention: the printing gum that the present invention makes is compared with sodium alginate with existing carboxymethyl starch printing gum, has following advantage:
1, because this printing gum is the compound of composite modified starch and single converted starch, can partly replace the sodium alginate thickener, so can obviously reduce the printing with reactive dye cost.
2, this printing gum is compared with the carboxymethyl starch of single sex change, has the silk of paste weak point, and the viscosity adjustable range is big, is beneficial to starching and stamp.
3, this built-up starch is to be that the basis makes with the carboxymethyl starch, and carboxymethyl starch has the characteristic of dissolving in warm water, belongs to normal-temperature dissolution type starch.When it used as thickener, modulation was convenient.
4, the carboxymethyl starch thickener is anionic property in the aqueous solution, and it sticks with paste the Heat stability is good of liquid, and is good with the compatibility of other chemical adjuvant.
5, single carboxymethyl starch thickener anti-wear performance is poor, and the crosslinked starch that contains in the built-up starch makes its performance optimization.
The specific embodiment:
