A kind of reactive printing composite paste material and its preparation method and application
Technical field
The present invention relates to a kind of reactive printing composite paste material and its preparation method and application.It is primarily adapted for use in cotton, fiber crops and
The printing with reactive dye of its blend fabric.
Background technology
In reactive printing gum, sodium alginate is traditional and important printing gum composition, and its rheological characteristic is close to Newtonian liquid
Body, has net, the stamp degree of depth and de-paste rate the most thoroughly, but the shortcoming of himself also can not be ignored, as easily gone mouldy, printing
Fine chemical wastewater definition processed is the highest, the paste producing time is longer, price is more high.
On market, complex printing gum is mainly the complex of carboxymethyl cellulose (CMC) and sodium alginate, and such is combined
Thing more independent sodium alginate thickener reduces cost to a certain extent, improves CMC thickener simultaneously and takes off the shortcoming that paste rate is low.But
Such thickener reduces cost, but does not reach the printing effect of sodium alginate.
As publication number CN 103741509A discloses a kind of reactive printing gum and method of production thereof, to the effect that will
Sodium alginate mixes with inorganic salt, carboxymethyl cellulose class thickening agent, although this invention maintains Sargassum to a certain extent
Acid sodium advantage, moreover it is possible to utilize inorganic salt addition reduce cost, but can not ensure simultaneously printing clearness, the stamp degree of depth,
Printing feel, resultant performance enhancements is inconspicuous.Include as publication number CN 103924456A discloses a kind of reactive printing gum
Carboxymethyl starch, sodium alginate, hydroxypropyl guar gum, nano silicon, albumen slurry are auxiliary agent.Thickener used by this invention,
Kind is more, complicated process of preparation, and the highest feel that directly affects of de-paste rate of modified starch, hydroxypropyl guar gum alkali resistance is not
Height, affects the stamp degree of depth, comprehensive printing effect relatively alginic acid sodium error.
Reactive printing gum research in recent years rests on the reduction cost of sodium alginate all the time, and modified cellulose ethers
The printing effect of class or modified starch series thickener relatively sodium alginate also has bigger gap.Although printing definition to improve,
But the stamp degree of depth is inadequate, or de-paste rate is the highest, is i.e. not reaching to the unification of the stamp degree of depth and feel, comprehensive printing effect
Undesirable.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency present in prior art, and a kind of stamp degree of depth height is provided, becomes
This low, good hand touch, reactive printing composite paste material easy to process and its preparation method and application.
