Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing solution for imparting a water-soluble polymer to a fabric, and a method for producing the same, in order to impart good quality to the fabric in an ink jet or spray dyeing method. The present invention relates to a fabric to which a water-soluble polymer is imparted by using a fabric, a dyeing method using the fabric, and a dyed product thereof.

[0002]

2. Description of the Related Art Conventionally, hand printing, roller printing, screen printing, transfer printing, and the like have been used as a technique for forming a pattern on a cloth. It is a method of preparing and performing. However, in recent years, a new method of inkjet printing or spray dyeing, which is a plateless system that does not require these screens or transfer paper, is being put to practical use. In these methods, prevention of bleeding is the most important issue in order to obtain a fine image on the fabric.
For example, the following method has been proposed.

(1) A method of performing a pretreatment for preventing bleeding of a fabric (2) A method of adding an additive for preventing bleeding to ink (3) A combination of the above (1) and (2) In the method of using an additive for preventing bleeding of the ink as in (2) and (3), even if the effect of preventing bleeding is large, the ink viscosity increases, the viscosity increases,
Due to an increase in insoluble components and the like, the ink ejection properties and reliability are reduced.

[0004] Regarding the cloth pretreatment of the above (1), a water repellent treatment for preventing the movement of ink (JP-A-60-9908).
No. 1) and a water-soluble polymer treatment (JP-A-61-55277) for improving the water retention of the fabric.

However, according to the knowledge of the present inventors, simply applying a water-soluble polymer liquid often causes less bleeding of each ink droplet but does not absorb it in a short time. If two colors of ink come into contact with the boundary with the portion, bleeding occurs and a sharp pattern cannot be obtained.

Therefore, in order to further increase the water absorption and water retention, a treatment method for increasing the surface area of the water-soluble polymer in the fabric is being studied. Japanese Patent Application Laid-Open No. H11-112489 discloses a method using a treatment liquid in which a finely divided water-soluble polymer is dispersed in oil. Since the molecules are provided as fine particles to the cloth, the surface area is large, and the bleeding of the ink can be stopped well. However, for example, since the dried fabric is in a state of being covered with a water-soluble polymer, the water-soluble polymer tends to fall off, and the bleeding prevention stability may be lacking. In addition, since it is oil-based, cleaning of the pretreatment device is inconvenient, and explosion-proof equipment for the treatment device is required.

On the other hand, Japanese Patent Publication No. 7-122224 discloses a method of applying an oil-in-water (O / W) emulsion in which a water-insoluble solvent is dispersed in an aqueous solution of a water-soluble polymer. According to the findings of the inventors, this method is preferable in terms of operability since it is a water-soluble treatment liquid as disclosed in Japanese Patent Application Laid-Open No. HEI 2-112489, and a water-soluble polymer has a fluffy cross-linked state in the fiber gap. This has the advantage that the water-soluble polymer is less likely to fall off. However, when an amount of the water-soluble polymer that satisfies a sufficient quality is applied, the viscosity of the treatment liquid becomes high, so that the application equipment is limited, and the operability may be poor.

[0008]

DISCLOSURE OF THE INVENTION The present invention provides a treatment for imparting a water-soluble polymer to a fabric which is excellent in operability for treating the fabric, hardly causes the water-soluble polymer to fall off from the fabric, and has a high bleeding prevention effect. It is intended to provide a liquid and a method for producing the same, an ink-jet or spray fabric, a method for producing the same, an ink-jet or spray dyeing method, and a dyed product thereof.

More specifically, examples of the natural paste include starches such as raw starch and soluble starch, gums such as locust bean, guar and tamarind, and seaweeds such as sodium alginate.

Examples of the semi-synthetic paste include celluloses such as methylcellulose, carboxymethylcellulose and hydroxymethylcellulose.

Examples of the synthetic paste include vinyl based resins such as polyvinyl alcohol and polyvinyl methyl ether, acrylic based polyacrylic acid, polymethacrylic acid, polyacrylate, polymethacrylate, and polyacrylamide, and maleic acid copolymer. Examples of the product include a copolymer of styrene and vinyl acetate, and polyvinyl pyrrolidone and polyethylene oxide.

The amount of the water-soluble polymer applied to the cloth is preferably 0.05-25% owf, more preferably 1-15% owf, from the viewpoint of preventing bleeding. In addition, if it is more than 25% owf, the degreasing property is deteriorated,
It is not economically preferable. From this viewpoint, in the treatment liquid of the present invention, the content of the water-soluble polymer in the treatment liquid is preferably 0.1 to 30% by weight, more preferably 0.1 to 20% by weight. If the content is more than 30% by weight, the viscosity of the processing solution is too high, and the operability is inconvenient. It is preferable that the pickup rate of such a processing liquid is appropriately adjusted so as to be the above-mentioned applied amount.

Among the water-soluble polymers, a polyacrylic acid-based water-soluble polymer is particularly preferred from the viewpoint of high bleeding prevention effect. The polyacrylic acid-based water-soluble polymer referred to herein is a polymer or copolymer mainly composed of various acrylates represented by acrylic acid and its sodium salt, and methacrylic acid and its sodium salt. And a polymer or copolymer composed of various methacrylates. The number average molecular weight of the polyacrylic acid-based water-soluble polymer is not particularly limited.
It is preferably 10,000, and more preferably 10,000 to 3,000,000. When the amount is 4,000,000 or more, the addition of a water-soluble high molecular weight effective for preventing bleeding to the treatment liquid results in too high a viscosity, which is inconvenient in operation.

In the present invention, a compound having a viscosity reducing effect on an aqueous solution of a water-soluble polymer is added to the treatment liquid in order to improve the operability of the treatment liquid and the operability when applying the treatment liquid to the fabric. It is preferred to add. The compound having a viscosity reducing effect on the aqueous solution of the water-soluble polymer referred to in the present invention differs depending on the water-soluble polymer used, but when added to the aqueous solution of the water-soluble polymer, when it is not added. There is no particular limitation as long as the viscosity decreases. For example, when polyacrylic acid is selected as the water-soluble polymer, for example, sodium chloride, sodium sulfate, ammonium sulfate, calcium chloride, water-soluble inorganic salts such as sodium tripolyphosphate, organic acid salts such as tetrasodium ethylenediaminetetraacetate, hydrochloric acid, Acids such as acetic acid are examples of compounds having a viscosity reducing effect on an aqueous solution of a water-soluble polymer. Among them, water-soluble inorganic salts such as sodium chloride, sodium sulfate and calcium chloride are particularly preferably used. It has a large viscosity reducing effect, is relatively inexpensive,
In addition, the solubility in water is high, and a required amount can be added.

0.1 × B ≦ A <30 where A: concentration by weight of a compound having a viscosity reducing effect with respect to an aqueous solution of a water-soluble polymer B: concentration by weight of a water-soluble polymer 1 × B ≦ A <20, more preferably 0.1 × B ≦ A <10. If the amount of the compound having a viscosity reducing effect with respect to the aqueous solution of the water-soluble polymer is less than 0.1 times that of the water-soluble polymer, the viscosity of the treatment liquid is significantly increased due to a change with time, and the operability is inconvenient. In addition, the concentration by weight of a compound having a viscosity reducing effect on an aqueous medium of a water-soluble polymer
Is 30% by weight or more, the compound is precipitated,
The operation becomes inconvenient, for example, the possibility that the dispersion stability of the processing liquid is lacking increases.

In the treatment liquid of the present invention, since the water-soluble polymer is dispersed in the oily medium and further dispersed in the aqueous medium, it is preferable to add a surfactant for the purpose of imparting stability. The surfactant here is not particularly limited as long as it does not practically inhibit dyeing or pigment dyeing, and nonionic, anionic, cationic and amphoteric surfactants may be used alone or in combination. Can be used.

The viscosity of the treatment liquid of the present invention is preferably from 1 to 100 cp, more preferably from 5 to 50 cp. It is preferable to appropriately adjust the composition, the component ratio, the molecular weight, and the like of the treatment liquid in order to fall within this range. Since the treatment liquid mainly contains an aqueous medium, it is difficult to reduce the viscosity to 1 cp or less. On the other hand, if it is 100 cp or more, the operability at the time of treating the fabric is significantly reduced, which is not preferable.

The treatment liquid of the present invention is prepared by dispersing a composition containing at least a water-soluble polymer and / or dispersing an oily medium in an aqueous medium, in other words, W / O.
It is important that this is a / W emulsion. The term “dispersion” as used in the present invention refers to dispersion, which may be in any colloidal state, such as dispersion, emulsification, suspension, fine dispersion, microcapsule, etc., which are used in a narrow sense.

The method for producing the treatment liquid of the present invention can be produced by a method in which at least a water-soluble polymer and a dispersant are mixed in an oily medium and further dispersed in an aqueous medium. In the process liquid production method of the present invention, it is more preferable to add a compound having a viscosity reducing effect to the aqueous solution of the water-soluble polymer. As the addition method, at least a water-soluble polymer and a dispersant are mixed in an oil-based medium, and further dispersed in an aqueous medium containing a compound having a viscosity reducing effect on an aqueous solution of the water-soluble polymer, or It is preferable to disperse at least a mixture of a water-soluble polymer and a dispersant in an oil-based medium in an aqueous medium, and then add a compound having a viscosity-reducing effect to the aqueous solution of the water-soluble polymer.

The treatment liquid can impart a water-soluble polymer to the cloth. The treatment method is not particularly limited, and can be applied by a pad method, a coating method, a spray method, an inkjet method, or the like.

The fabric obtained by the present invention has the advantage that the effect of preventing bleeding due to the rubbing of the fabric is small, although the cause is not clear. This is probably because the water-soluble polymer is partially dissolved in the aqueous medium and serves as a binder for the particles of the water-soluble polymer, so that it is difficult for the water-soluble polymer to drop off from the fiber.

The ink jet or spray dyeing method of the present invention is carried out using the above-mentioned cloth. Any known method can be used as the ink jet method or the spray method.

Also, in the same polyacrylic acid-based pretreated fabric (Examples 1, 2 and Comparative Example 2), when the pretreated fabric was rubbed before printing, the pretreated fabric of the present invention (Examples 1 and 2).
It was found that the bleeding prevention property did not decrease. This means that even if the pretreated fabric is stored for a long time, the effect is not reduced.

Further, in the present invention, the amount of the solvent used is small, and the burden on the environment can be reduced.

Example 4 The W / O / W emulsion treatment solution prepared from the solution A and the solution B described in Example 1 was treated with a pad-dry method on a 100% polyester fabric instead of nylon. A pre-treated fabric 6 was obtained. Further, printing was performed using the ink jet apparatus II and the ink set B.
