Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional pattern forming agent for forming a three-dimensional pattern on a fabric, a three-dimensional pattern forming method using the same, and a three-dimensional pattern forming product.

[0002]

2. Description of the Related Art Conventionally, there has been a physical or chemical method for forming a three-dimensional pattern on a cloth, and the physical method is a molding by contact pressure of an engraving roll under high-temperature heating, that is, embossing. , And shrinker processing. However, in this method, the cloth is inserted between the heating rolls under heavy pressure, so that the hardening of the texture and the flattening of the cloth are very large, and there is a defect that the hot roll causes metallic luster and sometimes thermal discoloration.

As a chemical method, a three-dimensional pattern forming method by printing or transfer printing has been disclosed. One of them is a method described in JP-B-47-23709, in which a naphthol derivative is used as a fiber contracting agent. However, naphthol is water-insoluble and cannot be uniformly present in an aqueous liquid only by mixing a sizing agent, tends to be uneven when applied, and not only does not provide uniform unevenness, but also in subsequent dyeing. It inhibits dyeability and tends to be uneven.

Japanese Patent Publication No. 58-55277 discloses a method using transfer. This is a method in which a transfer paper having a pattern formed with a treatment liquid containing a dye and a fiber swelling dissolving agent (hereinafter, referred to as a “dissolving agent”) is polymerized on a target fabric and treated at high heat and high pressure. In this, a treatment method in the case where the dissolving agent is a liquid and a solid is described.
There is a drawback that strikethrough occurs without remaining on the surface of the fabric, and the unevenness difference is weakened. When the dissolving agent is a solid, it is dissolved in a solvent, which is not preferable in terms of environment, safety and cost. In the case of dispersing, a high-viscosity liquid is used to maintain the dispersibility, but this causes problems such as uneven coating and aggregation of the dissolving agent. When the dissolving agent is water-soluble, it is generally not highly toxic and should not be used.

Further, Japanese Patent Application Laid-Open No. 10-298863 discloses a method of forming a three-dimensional pattern by an ink-jet method capable of various expressions. In the above invention, a high-viscosity (100 to 2000 cps) ink is used to prevent strikethrough, but a widely used inkjet printing apparatus adopts a low-viscosity type (1 to 10 cps) ink. Because
There is a drawback that clogging occurs and the fiber shrinkage agent does not reach the depth of the fabric, and irregularities tend to be insufficient. Further, the fiber shrinking agent used is a liquid substance or a substance having a low melting point at room temperature, and even when applied to a fabric, strikethrough or bleeding does not occur and a clear feeling of unevenness cannot be obtained. Furthermore, the irregularities become insufficient because the fiber shrinkage agent tends to volatilize or sublimate during the heat treatment.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in more detail. In order to form a clear three-dimensional pattern, it is necessary to cause the fiber contracting agent to efficiently react with the fibers and to contract the fibers. For that purpose, it is important to select a fiber contracting agent having a specific structure and physical properties. The details are described below.

In the present invention, in the three-dimensional pattern forming agent containing a fiber shrinking agent for shrinking fibers by heat treatment to form a three-dimensional pattern on a fabric, the fiber shrinking agent is solid at room temperature, more specifically, has a melting point of 50 to 50. Select one in the range of 200 ° C. Further, the fiber shrinking agent has a good melting point of 90-
Those at 200 ° C. are preferred. When the melting point is 50 ° C or less,
That is, even when applied to a fabric at room temperature, even when applied to a cloth, strike-through or bleeding occurs, and a clear feeling of unevenness cannot be obtained. Further, since the fiber contracting agent is easily volatilized or sublimates easily, unevenness is insufficient. Also, 200
If the temperature is higher than or equal to ° C., the stability of the fabric itself during heat treatment is impaired, and embrittlement occurs and the shape cannot be maintained.

[0011] Further, in order to shrink the polyester fiber, it is basically necessary to cut the polyester at its ester bond portion. Therefore, when the polyester and the aromatic ring of the fiber shrinking agent overlap, the carbon of the carbonyl group in the polyester molecule is reduced. A fiber shrinking agent having a substituent that causes a nucleophilic attack is preferred. That is, it is important that the fiber shrinking agent of the present invention is a compound in which at least one of a hydroxyl group and a carboxyl group is bonded to an aromatic ring, or an anhydride thereof.

Addition of an anionic surfactant and / or a nonionic surfactant as a dispersing agent can stabilize the dispersion state of the finely divided fiber contracting agent and is useful when used for a long period of time. Further, examples of the aqueous medium include ordinary water, ion-exchanged water, distilled water, and a water-soluble organic solvent.

The fiber shrinking agent has a molecular weight of 130.
It is preferably from 300 to 300. Fiber shrinking agents having a molecular weight of 130 or more are preferred because they are solid at room temperature and hardly sublimate, and generally have low toxicity. Further, when the molecular weight is 300 or less, it is easy to diffuse even inside the fiber having high density, and the fiber is well adsorbed, so that a three-dimensional pattern excellent in unevenness is formed.

Further, when 90% or more of the fiber shrinking agent is adjusted to have a particle size of 15 μm or less, a dispersion liquid having a well-balanced particle and a uniform concentration distribution can be obtained. Is preferred. In particular, when the ink is applied by the ink jet method, the ejection amount from the nozzle is stable, and unevenness and head clogging hardly occur.

Further, since the fiber shrinking agent can be uniformly applied, the average particle size of the fiber shrinking agent is 0.01 to 10 μm.
It is preferable to make the particles fine so as to be in the range of m. Here, the average particle size is synonymous with the average particle size. By setting the average particle size to 0.01 μm or more, aggregation of the fiber contracting agent hardly occurs and the dispersion state can be stably maintained. Further, when the thickness is 10 μm or less, clogging of the screen mesh or the inkjet nozzle is prevented, and when applied to the fabric, the fiber shrinkage agent can penetrate into the interior of the fiber. Since the fibers can be efficiently shrunk, a three-dimensional pattern excellent in unevenness can be formed.

Incidentally, the heat treatment temperature at which a three-dimensional pattern can be formed is a temperature at which the fiber contracting agent can react with the fibers, specifically 100 to 200 ° C., preferably 130 to 200 ° C. Therefore, if the fiber shrinking agent sublimates and volatilizes when the fiber is heated to 130 to 200 ° C., there is a problem that an intended three-dimensional pattern cannot be obtained. The present inventors have grasped that it is also an important factor to select a fiber contracting agent which is difficult to sublimate and volatilize based on this point. That is, the fiber shrinking agent is preferably one that hardly causes sublimation and volatilization, and a fiber shrinking agent having a weight reduction rate of 20% or less when the temperature is increased from room temperature to 130 to 200 ° C. is preferably used. More preferably, the weight reduction rate is 15% or less.

Specifically, the fiber shrinking agent can be selected by raising the temperature of the fiber shrinking agent at 10 ° C./min by the TGA method and measuring the weight loss rate. Here, the TGA method is a so-called thermogravimetric analysis method in which a change in weight when a sample is heated is continuously measured. By using a fiber shrinking agent having a weight reduction rate of 20% or less, it is possible to suppress a decrease due to sublimation or volatilization of the fiber shrinking agent when shrinking the polyester fiber, and it is possible to efficiently form irregularities.

Further, if an ink containing a high concentration of a fiber contracting agent can be prepared, the amount of ink applied can be reduced, so that the scanning speed of the ink jet apparatus can be increased and the bleeding of the fiber contracting agent can be suppressed. . However, the fiber shrinking agent may be solidified or gelled by drying to cause clogging of the ink jet head. Therefore, it is preferable to add a non-volatile polyhydric alcohol to this ink since stable ink jet printing becomes possible. Specific examples of the polyhydric alcohol include ethylene glycol, diethylene glycol, propylene glycol, butylene glycol, hexanetriol, thiodiglycol, hexylene glycol, glycerin, triethylene glycol, tetraethylene glycol, dipropylene glycol and the like.

In particular, a raised fabric made of a pile is preferable in order to more effectively show a three-dimensional pattern. The material may include a polyester fiber, and a composite product with a fiber other than the polyester fiber may be used.

The application method may be a screen method, a roller method, an ink-jet method, or the like, but an ink-jet method is preferred in which various irregularities can be expressed by adjusting the amount of application. That is, in the ink jet system which is being diversified, the three-dimensional pattern forming agent can be uniformly applied, and a clear feeling of unevenness can be obtained.
When the ink jet method is used, the viscosity of the three-dimensional pattern forming agent is set to 1 to 10 cp in order to stabilize the dispersion of the fiber contracting agent.
It is preferable to adjust to s.

Any of an on-demand method such as a jet (registered trademark) method and an electrostatic suction method can be adopted.

In the case of the ink jet system, it is preferable to apply a pretreatment agent comprising an ink holding agent and an aqueous medium to the cloth before applying the three-dimensional pattern forming agent. Examples of the ink retainer include starch, natural rubber, natural gum, natural paste such as sodium alginate, hydroxyethylcellulose, carboxymethylcellulose, methylcellulose,
Semi-synthetic sizing agents such as hydroxymethylethylcellulose, processed starch, guar gum, etc., synthetic sizing agents such as polyvinyl acetate, polyoxyethylene, polyvinyl alcohol, sodium polyacrylate, polyacrylate, polyacrylamide, starch-acrylic copolymer, etc. No.
