Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fiber dyeing method, particularly to a textile printing and ironing dyeing method.

The present invention relates to a method of continuously and uniformly and beautifully printing and ironing dyeing by using a foam composition having a fine spatial structure and being stable for a long time.

By supplying a dyeing liquid composition that itself has a high viscosity to a rotating printing roll, a desired pattern or shape is applied to the target fabric.
Textile dyeing means for transferring and printing patterns in two colors, etc. is widely practiced as the most highly efficient dyeing method.

Conventionally, there has been a method for increasing the viscosity of a dye solution for textile printing to a viscosity suitable for application to this dyeing method.

Generally, methods using emulsified liquid hydrocarbons such as mineral spirits and methods using natural polymer adhesives have been used.

However, in recent years, a method has been developed in which a nonionic surfactant and an anionic surfactant are added as foaming agents to a dyeing solution that has been slightly thickened with a dye fixing agent and a small amount of a sizing agent to create a foamed dyeing composition. 1974-38474 and 1977-38474
This was proposed by Publication No. 5383.

In the invention disclosed in the above Japanese Patent Publication No. 47-38474,
When dyeing thick fabrics such as felt, carpets, and blankets, it contains a foaming agent and has a viscosity of 100 to 90 depending on the sizing agent.
A method has been proposed in which a dye solution adjusted to 0 cps is foamed so that the apparent volume becomes 2 to 5 times larger.

However, as a result of actually re-testing the invention, it was found that it was difficult to reproduce a good foamed dye solution due to the small amount of natural polymer thickeners such as alginate sorter and carboxymethylcellulose used, and that when using the dye solution, Therefore, it was found that it is difficult to apply it to textile printing that requires precise dyeing properties, such as for general clothing. Incidentally, if the foam composition itself has a high viscosity, the volume change during printing will be reduced, but on the other hand, since the viscosity change is large, it will be difficult to stably supply a constant amount of the composition, which will impede practical use. It becomes impossible to desire certain processing.

Therefore, in order to eliminate the above-mentioned drawbacks, we used an aqueous dispersion of natural or synthetic resin used as a pigment binder, which hardly thickened the dye liquor and exclusively used the action of the foaming agent to produce a dye with a diameter of 2.
It was proposed in JP-A-52-5383 to prepare a foam composition containing spherical air bubbles of 00μ or less and having a volume ratio of dye liquor to air of 1:1.5 to 4.0. There is.

However, even with this improved method, the colorants that can be used are essentially limited to pigments, and so-called dyes, such as disperse dyes,
With basic dyes, reactive dyes, direct dyes, etc., due to the presence of a fixing agent, the color development is insufficient, stiffness, fastness is significantly reduced, or the texture of the product becomes very rough. However, some drawbacks remain.

Therefore, the more recently published patent application publication 55-50
No. 0756, the gist of which is specifically directed to the application of colorant-containing foam compositions, to maintain accurate foaming ratios and to minimize the volume increase of colorant-containing foam compositions when used in textiles. The following is a summary of the points to be noted.

That is, [by introducing an inert gas, the foaming ratio is preferably increased to an upper limit of 10 times from 0.1 g/cc to 0.7
The foamed textile printing composition has a foam density in the range of 5 g/cc and a foam growth inhibitor is introduced into the foamed composition once the desired expansion ratio has been reached to limit further foaming. This foam growth inhibitor is preferably present at an upper limit of 10 to 15% by weight of the total composition, and its introduction provides foam growth control. Furthermore, the introduction of foam growth inhibitors during the initial formulation has only limited effectiveness. However, when we examine the method described in the specification of the above-mentioned publication in detail, we find that when we name the actual processing method, the foam growth inhibitor has a defoaming effect, so it is necessary to constantly check the upper limit usage amount. However, if left for a long time, the foam composition such as foam viscosity changes significantly, and defects such as color unevenness, color blurring, and bleeding occur, making it difficult to obtain uniform dyed products continuously. It was known that there was a problem.

As a result of extensive research, the present inventors have discovered a foam dyeing method that can continuously produce uniform and beautiful dyed products not only at room temperature but also at high temperatures, and have thus arrived at the present invention. That is, foam stabilizers, water-soluble polymer thickeners,
The present invention provides a foam dyeing method characterized in that a foam composition obtained by foaming an aqueous dyeing solution containing a surfactant, a dye, and a dyeing aid is applied to an object to be dyed to develop color.

The foam stabilizer used in the present invention is polystyrene sulfonic acid, polystyrene sulfonic acid salt, or a polymer compound containing one or more styrene sulfonic acid groups in the molecule. Polystyrene sulfonate includes sodium salt and potassium salt.

Either lithium salt or ammonium salt is fine.

Examples of polymeric compounds containing one or more styrene sulfonic acid groups in the molecule include copolymers of styrene sulfonic acid and acrylic acid, copolymers of styrene sulfonic acid and maleic anhydride, and polyalkylene oxides of styrene sulfonic acid. Any polymer compound containing one or more styrene sulfonic acid groups in its molecule, such as an adduct, obtained by a known reaction method such as a polymerization reaction, condensation reaction, or addition reaction, can be used.

Further, these polymer compounds may be acids or their salts, such as sodium, potassium, lithium, and ammonium salts.

The molecular weight of polystyrene sulfonic acid or its salt, or a polymer compound containing one or more styrene sulfonic acid groups in the molecule, is 500 to 10 million, preferably 5000-6.
It is 0,000,000. When the molecular weight is less than 500, it is difficult to maintain the foam composition stably for a long time at high temperatures, and the molecular weight
If the fi is 10 million or more, the stringiness is high, so
A foam composition that is stable for a long time cannot be obtained. Therefore, it is possible to continuously obtain dyed products with good level dyeing properties.

Since foam stabilizers are effective even when used in small amounts, the amount of foam stabilizers in the dyeing solution is 5.0% by weight or less, preferably 2.0% by weight. In the present invention, by incorporating a foam stabilizer, the foam viscosity, foam density, etc. of the foam composition can be maintained uniform for a long time not only at room temperature but also at high temperatures.

The water-soluble polymer thickener used in the present invention has thickening and foam regulating effects, and maintains the stability of the foam composition.

Such water-soluble polymer thickeners include, for example, natural gums such as xanthan gum, guacam, and tamarind gum, carboxymethyl starch, cationized starch, cyanethylated starch, starch derivatives, carboxymethyl cellulose, etc. Seaweed polysaccharide derivatives 1 such as cellulose derivatives, sodium alginate, alginate alkylene glycol ester, water-soluble synthetic polymer thickeners such as styrene-maleic acid copolymer, acrylic acid-vinyl acetate copolymer, etc. Any synthetic water-soluble polymeric thickener can be used. these are,
Optionally, two or more types may be used in combination.

When the water-soluble polymer thickener used in the present invention exhibits high viscosity when used in a small amount, it is sufficient to use the IO weight percent or less in the staining solution. However, the amount used can be within any range.

As the surfactant used in the present invention, any surfactant that acts as a foaming agent and has foaming power can be used.

If necessary, two or more of these may be used in combination.

Examples of such surfactants include nonionic surfactants such as polyethylene glycol nonylphenyl ether, polyoxyethylene stearylamine, oleic acid jetanolamide, lauryl dimethylamine oxide, and sorbitan monomyristate.

Also, sodium octylbenzenosulfonate, lauric acid triethanolamine salt, oleyl sulfate sodium salt, sodium lauryl sarcosine, sodium dodecyl phosphate, sodium stearylmethylsulfosuccinate, sodium N-methyl-N-oleyl taurate, lauryl phosphorus. fermentation ester, polyoxyethylene lauryl ether sulfate, -to sodium salt, anionic surfactant with IJ, laurylethylaminochloride, octylpyridinium chloride, N-N-stearylmethylmorpholinium chloride, polyethylenepolyamine lauric acid amide hydrochloride , dilauryldimethylammonium chloride, myristyldimethylbenzylammonium chloride, and the like can be used.

Sarah, N-N-dimethyl-N-stearyl-N-carboxyethylene ammonium bedaine, N-N-sodium dilaurylaminocaprate, N-lauryl-N-
Amphoteric surfactants such as N-diethyl-N-sulfomethylene ammonium betaine, 2-myristyl-1-hydroxyethyl-1-carboxymethylimidazolium sodium salt can be used.

If the amount of surfactant used is too small, foaming will be insufficient and a stable foam composition will not be obtained; if too much is used, the foam composition will change significantly when left for a long time at high temperatures, resulting in uniform color development. is not obtained. Therefore, in the staining solution, 0.1 to 5
．． Oi J is preferably in the range of 1%.

In the present invention, all common dyes such as disperse dyes, acid dyes, cationic dyes, and reactive dyes can be effectively used. Although the aforementioned foam stabilizer used in the present invention is anionic, in addition to its unique performance, it can be used in combination with cationic dyes because the amount used is only natural nails and the purpose is achieved. Foam dyeing with cationic dyes is also possible because no complex salts are produced.

In addition, as a dye, for example, acetic acid, tartaric acid, citric acid,
Malic acid, urea, sodium carbonate, etc. can be added, and preservatives and anti-mold agents can also be added to prevent the stain from rotting and molding.

To prepare the dyeing solution in the present invention, first, a dye and a dyeing aid selected according to the material of the material to be dyed are dissolved or dispersed in water, and then a water-soluble polymer thickener previously dissolved in water is added. and a surfactant may be added. The viscosity of the dyeing liquid thus prepared can be varied depending on the purpose of the dyeing object, such as the material, design, and type of dyeing machine.

When the prepared dyeing liquid is stirred with a mixer, foaming occurs easily and the desired foaming composition is obtained. Examples of the mixer used in this foaming process include a whipper type mixer,
Oaks Mixer-0 (manufactured by Aarhusmein), Fine Form L■ (newly manufactured by Suehiro Kakoki), High Mixer [
It is possible to use a conventional foaming stirrer such as "Phase" (manufactured by Toshisha Co., Ltd.), and a desired foamed composition can be obtained in a short time with a relatively small amount of stirring energy.

However, the type of mixer used and the foaming conditions are completely unrelated to the essence of the present invention.

The foamed product obtained as described above has a volume that is 15 to 10 times the volume before foaming (hereinafter, this magnification is referred to as the "foaming ratio"), and the diameter of the bubbles is Average about 100μ
It is. However, in order to further stabilize the foam composition, it is preferable to further subdivide it into fine bubbles with a diameter of 30μ or less using a Colloid IS mill, homomixer, or other high-speed mixing means. becomes higher as the constituent bubbles become finer.

Air or an inert gas such as nitrogen or carbon dioxide is used to form bubbles. These gases are naturally incorporated into the composition by stirring, but if they are forcibly introduced under appropriate pressure, they will foam. The time required can be significantly reduced.

In addition, by stirring only the pre-dissolved water-soluble polymer binder and surfactant using the mixer, an IJ foam composition containing a dye is obtained. A foam composition for dyeing can also be prepared by preparing a dye solution in which the dye and dyeing aid are dissolved or dispersed in water and uniformly mixed with the foam composition described above.

For such mixing, you can use a homo mixer, a Whizpur type stirrer, or a Whizpah type stirrer, but it is convenient to use a Hoytsuno 1° type stirrer. The number and mixing time are not limited.

In the present invention, the foam composition thus obtained is applied to the object to be dyed, such as clothing fabric, etc., to develop color. Examples of this application method include rotary screen printing, flat Normal textile printing methods such as screen printing, hand screen printing, roller printing, horizontal pad method, steam pad method, knife over roll method, floating knife method, applicator nozzle method 1j, and normal ironing dyeing method are all available. Can be used effectively.

As for the coloring step, known methods such as high-pressure steaming, high-temperature steaming, drying treatment, fixing treatment, etc. 1 can be used depending on the dye or the material of the object to be dyed. Thereafter, finishing steps such as soaping, washing with water, and drying with γS are carried out as usual.

Normally, the finishing process in the foam printing method is often much simpler than conventional processes, such as washing with water and drying.

Also, the material of the object to be dyed may be suitably selected, such as acrylic napkin,
If a fabric such as acrylic pile is used and appropriate color development conditions such as wet steaming are selected, a dyed product with excellent fastness can be obtained only through the color development process.

Therefore, finishing steps such as soaping, washing, and drying can be omitted. In the present invention, it is possible to obtain a foam composition that remains unchanged even after being left at a high temperature of around 40° C. for a long period of time, due to the effective action of the foam stabilizer at high temperatures. or,
The fact that the foam stabilizer exhibits an effective effect even at high temperatures can be inferred from its chemical structure. This is due to the excellent temperature stability of the foam stabilizer itself and the fact that physical properties such as surfactant ability fj do not change even at high temperatures.

Therefore, it is possible to obtain a very stable foam composition not only at room temperature but also at high temperature, making it possible to dye with good quality and good reproducibility. Therefore, the dyed object (hereinafter referred to as product 0) dyed according to the present invention has extremely good level dyeing properties and hue, and is also excellent in color fastness to rubbing.

In the present invention, unlike conventional printing pastes 1, there is no need to use different dyes depending on the type of dye, so a variety of products can be obtained. Examples include cotton products, wool products, acrylic fibers, synthetic fiber products such as polyester fiber IJ, blended fiber products such as Tetoron/cotton, etc.

In addition, in the case of dyeing synthetic w&fiber fabrics with low water absorption, and dyeing unscoured synthetic fiber fabrics with raw thread oil attached,
Shows excellent wetting effect. For this reason, uneven dyeing caused by sagging and insufficient staining, which is common in foam dyeing, is greatly improved, and practical dyeing becomes possible.

Hereinafter, the mode of carrying out the invention and its effects will be explained with reference to Examples. However, the description is merely for explanatory purposes and is not intended to limit the technical scope. (Note that parts and % indicate double star standards.)
