The paint pad dyeing afterfinish liquid is prepared by uniformly mixing the following components by weight: 50-200 parts of a polymer emulsion, 1-3 parts of a penetrant, 1-3 parts of color fixing agent, 50-200 parts of a migration inhibitor water solution, 0.5-1 part of a wetting agent, 1-2 parts of a dispersant, 50-200 parts of water, and 0-100 parts of color paste; the migration inhibitor water solution is selected from a hydroxypropyl methyl cellulose water solution; the concentration of hydroxypropyl methyl cellulose is 1-5 g/L. the paint pad dyeing afterfinish liquid and the preparation method are applicable to pad dyeing of products with the thickness of more than 1.0 mm in fields such as textile, non-woven and composite materials, and achieves the effect that the inner layer and the outer layer of a thick non-woven material after dyeing are uniform.
Description
Technical field
The present invention relates to Pigment Padding field, relate in particular dressing liquid and preparation method after a kind of Pigment Padding, its pad dyeing for weaving, non-woven, composite etc. has very outstanding effect, for thickness, is especially product more than 1.0mm.
Background technology
Pigment Padding flow process is short, equipment is simple, easy to operate, chromatogram neat, lovely luster, steady quality, the percentage of A-class goods are high, favorable reproducibility, saving labour, energy-conservation and economize on water, and generally favored by the world.In the U.S.'s approximately 80% this explained hereafter of painting cloth, and China 20% left and right only, vast dyeing and finishing and printing and dyeing assistant worker just jointly make great efforts research and development, make Pigment Padding technique constantly perfect, become process for cleanly preparing worthy of the name, actively expand the extent of spreading amd application.
On coating, dyeing and weaving thing is different from dyestuff, because of coating water insoluble, to fiber without substantivity, in dyeing course, be evenly spread in paint particles in water and the adhesive of emulsion dispersion and together padded on fabric, after drying or baking, water evaporates, adhesive bag embedding coating particles forms the film of tridimensional network, sticks to fiber surface, thereby complete on whole, dyes process.
Because most of fibers are with negative charge in dye bath, and conventional coating and adhesive are also electronegative, because electrostatic repulsion causes the adhesion of coating and fiber not firm, there are at present two kinds of methods to address the above problem, a kind of is to carry out cation-modified to fiber, another kind is cation paint and the adhesive of selecting very, these two kinds of methods all can realize coating smoothly on dye.In this external dyeing drying course, along with the evaporation of moisture, the hydrone of pollutant inside is constantly along capillary flow to evaporating surface, when capillary diameter is greater than the diameter of dye molecule, when capillary is full of by water again, dye molecule can be shifted to evaporating surface with hydrone, thereby produces migration phenomenon.The generation of migration phenomenon is totally unfavorable for the level dyeing of fabric, need to add appropriate migration inhibitor, migration inhibitor is generally polymer substance, owing to producing absorption between macromolecule long-chain and dyestuff, form loose agglomerate, cause dyestuff to be got off by capillary retention, and can not move with the movement of hydrone, thereby reach the object of anti-migration.More conventional migration inhibitor has sodium alginate, polyacrylamide etc. at present.
As Chinese patent 200810123958.4 < <, a pigment dyeing adopts cationic type coating mill base, cationic adhesive or nonionic adhesive with cationic binder emulsion and its production and use > >, guaranteed the binding strength of coating and fiber, do not need DYED FABRICS to carry out cationization preliminary treatment, but it is not to proposing corresponding scheme adding of migration inhibitor.
And for example the coating-dye composite staining method > > of a Chinese patent 201010557700.2 < < ribbon product adds coating and dyestuff in compound stain solution simultaneously, solved the indeterminable Fastness Problems of simple pigment dyeing, although it has the migration inhibitor of adding, but to its composition, do not illustrate.
Summary of the invention
The object of the present invention is to provide dressing liquid after a kind of Pigment Padding, to solve thick type product, the inhomogeneity problem of especially thick type nonwoven material dyeing ectonexine.
In order to reach above-mentioned purpose, solution of the present invention is:

Further, this macromolecule emulsion is selected from one or more in acrylic emulsion, polyaminoester emulsion, butylbenzene, NBR latex.
Further, this bleeding agent is non-ionic surface active agent.
Further, this bleeding agent is selected from fatty alcohol polyethenoxy ether class or polyoxyethylene ester class.
The preparation method who another object of the present invention is to provide dressing liquid after a kind of Pigment Padding, wherein, comprises the steps:
1. under the condition stirring that remains a constant speed, by the dispersant of the mill base of 0-100 weight portion and 1-2 weight portion, be added in the water of 50-200 weight portion;
2. in water, add successively again the macromolecule emulsion of 50-200 weight portion, the color-fixing agent of the bleeding agent of 1-3 weight portion, 1-3 weight portion, the wetting agent of the migration inhibitor aqueous solution of 50-200 weight portion, 0.5-1 weight portion, the stirring that remains a constant speed, until each component is fully mixed; This migration inhibitor aqueous solution is selected the hydroxypropyl methylcellulose aqueous solution, and the concentration of hydroxypropyl methylcellulose is 1-5g/L.
Further, this macromolecule emulsion is selected from one or more in acrylic emulsion, polyaminoester emulsion, butylbenzene, NBR latex.
Further, this bleeding agent is non-ionic surface active agent.
Further, this bleeding agent is selected from fatty alcohol polyethenoxy ether class or polyoxyethylene ester class.
Adopt after said structure, dressing liquid and preparation method thereof after a kind of Pigment Padding the present invention relates to, its by the choose reasonable migration inhibitor aqueous solution with and and macromolecule emulsion between proportion relation, so at least there is following beneficial effect:
One, hydroxypropyl methylcellulose is a kind of nonionic cellulose ether, not only has hydrophilic effect, and also has good associativity with fiber, and it is thick in rear dressing liquid, can adsorb mill base, and mill base is distributed in whole dye liquor equably;
Two, in pad dyeing process, because hydroxypropyl methylcellulose and fiber have good associativity, can be evenly distributed in fiber surface with macromolecule emulsion together with, formation one deck membranoid substance, is evenly being coated on fiber surface by dye granule;
Three,, in drying course, due to the anti-migration effect of hydroxypropyl methylcellulose, guarantee that dye granule is with moisture evaporation, the object of dying on reaching evenly;
Four, hydroxypropyl methylcellulose also has the effect that improves adhesive film forming property, and it can further improve the COLOR FASTNESS of pigment dyeing with coordinating of macromolecule emulsion.In addition, by the mutual proportion relation of rational selection, also avoided affecting rear dressing liquid mobility because of the toughness of hydroxypropyl methylcellulose simultaneously, and then caused the problem of pad dyeing degradation.
