Abstract
The invention belongs to the field of textile printing and dyeing, in particular to a screening method for a foam dyeing chemical. The screening of dyes is operated by measuring the foaming effect in the invention, which comprises the following steps: (a) flat proof. Monochromatic disperse dyestuff and reactive dyes are weighed and mixed with water. Then the mixture is subject to slow stirring and accelerated stirring successively. (b) measurement of foaming effect. Record the time required during the process of lather collapse to half the amount of liquid separated out. The screening of dyes is operated by measuring the foaming effect in the invention, thereby saving the time of screening and lowering the difficulty of measuring Rf value in prior art.
Description
Technical field
The invention belongs to the textile printing and dyeing field, be specifically related to a kind of foam dyeing chemicals screening technique.
Background technology
Textile is before dyeing, need the foam dyeing chemicals is screened, its screening process is to take by weighing to disperse to dye reactive dye and mix with water, make dyestuff fully be dissolved in the water by stirring, draw blobs of dye again on filter paper, after treating that it all is diffused on the filter paper, the diameter that spreads on filter paper according to each dye well water is judged the Rf value size again.Diameter is big, and its Rf value is big; Otherwise diameter is little, and Rf value is just little.The dyestuff that the Rf value of being surveyed is little need be a reference point with the Rf value of water, adjusts out the rate of appending.The shortcoming of this method is a dyestuff when measuring the Rf value size, difficultly regulates its Rf value, and consuming time longer in this test process, and testing procedure is loaded down with trivial details, and this has brought certain inconvenience to subsequent production.
Summary of the invention
Technical matters to be solved by this invention is that a kind of foam dyeing chemicals screening technique is provided.
Foam dyeing chemicals screening technique of the present invention screens dyestuff by surveying foaming effect, and its step is as follows:
A, monochrome are drawn a design: take by weighing solid shade of disperse dye and/or reactive dye, add water and mix, stir at a slow speed, quicken then to stir;
B, survey foaming effect: the needed time of 1/2 liquid is separated out in the record lather collapse;
Disperse dyes were at least a in disperse red, disperse yellow, the disperse blue during monochrome was drawn a design, and reactive dye are at least a in reactive red, reactive yellow, the reactive blue, and disperse dyes and/or reactive dye add water to mix back concentration be 6～12g/L.
In monochrome was drawn a design, the rotating speed of Jiao Baning was 300～600r/min at a slow speed, and mixing time is 2～6 min, and the rotating speed that quickens to stir is 1000～1400r/min, and mixing time is 3～7 min.
Lather collapse is separated out the needed time of 1/2 liquid and is preferably 5～7min in the above-mentioned survey foaming effect.
Beneficial effect of the present invention is, owing to adopted above-mentioned screening technique, the Rf value of test dye again, directly test its foaming effect, the time that the recording dye foam reduces gets final product, and surveys before having reduced than the difficulty of moving, this method is easy to save time, dirigibility and versatility height.
