Abstract
The invention relates to a method for preparing reactive dyeing and printing paste of linen fabric. The method comprises the following steps: preparing carboxymethyl starch; preparing a mixture of carboxymethyl starch and nanosilicon dioxide; preparing albumen size and mixing ingredients. The process disclosed by the invention is simple, and the prepared reactive dyeing and printing paste mainly comprises nanosilicon dioxide modified starch, carboxymethyl starch and guar gum. The performances of the paste can meet the printing and dyeing requirements, the traditional sodium alga acid can be replaced, the production cost of a printing and dyeing enterprise is reduced, and the paste disclosed by the invention is especially applicable to reactive dyeing of the linen fabric.
Description
Technical field
The present invention relates to the preparation method of the active dyeing paste of a kind of sodolin.
Background technology
In printing with reactive dye, thickener is generally used as thickener and regulates the rheological property of mill base.Sodium alginate because it does not react with REACTIVE DYES, tinctorial yield is high, chromatogram is complete, easily from fabric wash away, the advantage such as fabrics feel soft, be the first-selection of active dye printing thickener always.But its price is more expensive, stamp cost is relatively high, and therefore finding the thickener that a kind of # with low cost can print meticulous colored type has become the task of top priority.
Starch is a kind of renewable resource, and its deposit is abundant, easily obtains, but has active hydroxyl on its molecule, easily reacts with dyestuff, therefore in the application of active dye printing thickener, is restricted.
Summary of the invention
The object of the invention is to: overcome the defect of above-mentioned prior art, propose the preparation method of the active dyeing paste of a kind of sodolin.
In order to achieve the above object, the preparation method of the active dyeing paste of sodolin that the present invention proposes, comprises the steps:
The first step, cornstarch is fully mixed with NaOH, monoxone after, the extruding of use screw extruder, the second half at extruder is sprayed formaldehyde to material, and final drying makes, and described cornstarch, farina, NaOH, chloroacetic mass ratio are 100:5:8;
Second step, carboxymethyl starch add in deionized water after mixing with silica flour, and add NaOH and methyl alcohol, after being hydrolyzed, dry purification obtains nano SiO 2 modified starch, wherein, and carboxymethyl starch: silica flour: NaOH: the quality proportioning of methyl alcohol is: 110:6:0.2:0.4;
The 3rd step, the maize straw of pulverizing and absolute alcohol, NaOH are carried out to quaternization, and then under nitrogen protection, add monoxone and epoxychloropropane to react; Then add NaOH to continue slaking, finally utilizing salt acid for adjusting pH is 8, after being dried, makes carboxymethyl cellulose;
The 4th step, according to weight proportion, by 50 parts of nano SiO 2 modified starch, 24 parts of carboxymethyl celluloses, 28 parts of modified guars are poured in agitator and are uniformly mixed, and to obtain final product, described modified guar is hydroxypropyl guar gum or cation guar gum.
The preparation method of the active dyeing paste of sodolin of the present invention also has following improvement:
1,, in the 4th step, also pour the Sodium Benzoate of 5 parts by mass into agitator.
2,, in the 4th step, also pour the sodium thiosulfate of 3 parts by mass into agitator.
3,, in the 4th step, also pour the tamarind gum of 10 parts by mass into agitator.
Technique of the present invention is simple, the active dyeing paste of preparation mainly comprises nano SiO 2 modified starch, carboxymethyl cellulose and modified guar, the various aspects of performance of thickener can meet printing and dyeing demand, and alternative traditional sodium alginate has reduced the production cost of printing and dyeing enterprise.Thickener of the present invention is particularly useful for the activity printing and dyeing of sodolin.
In thickener prepared by the present invention, added modified guar, more traditional dyeing paste has more excellent performance.As good rheological characteristic, be difficult for knot and scraping on the edge of a knife, stamp cutter defect is less; Good penetrability, printed surface good level-dyeing property; Paste making rate is high, and washing performance is good; Water retention property is good, can be used for the stamp acid and alkali-resistance of hydrophobic fibre fabric, and electrolyte-resistant is good with all kinds of fastness.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described.
The preparation method of the active dyeing paste of the present embodiment sodolin, comprises the steps:
The first step, cornstarch is fully mixed with NaOH, monoxone after, the extruding of use screw extruder, the second half at extruder is sprayed formaldehyde to material, and final drying makes, and described cornstarch, farina, NaOH, chloroacetic mass ratio are 100:5:8;
Second step, carboxymethyl starch add in deionized water after mixing with silica flour, and add NaOH and methyl alcohol, after being hydrolyzed, dry purification obtains nano SiO 2 modified starch, wherein, and carboxymethyl starch: silica flour: NaOH: the quality proportioning of methyl alcohol is: 110:6:0.2:0.4;
The 3rd step, the maize straw of pulverizing and absolute alcohol, NaOH are carried out to quaternization, and then under nitrogen protection, add monoxone and epoxychloropropane to react; Then add NaOH to continue slaking, finally utilizing salt acid for adjusting pH is 8, after being dried, makes carboxymethyl cellulose;
The 4th step, according to weight proportion, by 50 parts of nano SiO 2 modified starch, 24 parts of carboxymethyl celluloses, 28 parts of hydroxypropyl guar gum, 5 parts of Sodium Benzoates, 3 parts, sodium thiosulfate, 10 parts of tamarind gums are poured in agitator and are uniformly mixed, and to obtain final product.
In this example, hydroxypropyl guar gum can be replaced with cation guar gum.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
