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 materials and its preparation method and application.It is primarily adapted for use in cotton, fiber crops and
The printing with reactive dye of its blended fabric.
Background technique
In reactive printing gum, sodium alginate is traditional and important printing gum ingredient, the intimate Newtonian liquid of rheological characteristic
Body, has well a net, stamp depth and de- paste rate thoroughly, but its own the shortcomings that also can not be ignored, be such as easy mildew, print
Fine chemical wastewater clarity processed is not high, the paste producing time is longer, price is higher etc..
Complex printing gum is mainly the compound of carboxymethyl cellulose (CMC) and sodium alginate in the market, such is compound
The more independent sodium alginate thickener of object reduces costs to a certain extent, while improving CMC thickener and taking off the low disadvantage of paste rate.But
Such thickener reduces costs, but does not reach the printing effect of sodium alginate.
If publication number CN 103741509A discloses a kind of reactive printing gum and its method of production, to the effect that will
Sodium alginate is mixed with inorganic salts, carboxymethyl cellulose class thickener, although the invention maintains seaweed to a certain extent
The advantages of sour sodium, moreover it is possible to reduce cost using the additive amount of inorganic salts, but cannot guarantee simultaneously printing clearness, stamp depth,
Feel is printed, resultant performance enhancements are unobvious.Include as disclosed a kind of reactive printing gum in publication number CN 103924456A
Carboxymethyl starch, sodium alginate, hydroxypropyl guar gum, nano silica, albumen slurry are auxiliary agent.Thickener used in the invention,
Type is more, preparation process is complicated, and the de- paste rate of modified starch is not high to directly affect feel, and hydroxypropyl guar gum alkali resistance is not
Height influences stamp depth, and comprehensive printing effect is compared with alginic acid sodium error.
Reactive printing gum research in recent years rests on the reducing in cost of sodium alginate always, and modified cellulose ethers
There are also larger gaps compared with sodium alginate for the printing effect of class or modified starch series thickener.Although printing clarity improves,
But stamp depth is inadequate or de- paste rate is not high, i.e., does not reach the unification of stamp depth and feel, comprehensive printing effect
It is undesirable.
Summary of the invention
It is an object of the invention to overcome the above deficiencies in the existing technologies, and provide a kind of stamp depth it is high, at
This low, good hand touch, reactive printing composite paste material easy to process and its preparation method and application.
