[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink-jet fabric used to reproduce an original image read by a computer by printing ink with an ink-jet printer.

[0002]

2. Description of the Related Art In order to sharpen the outline of an image reproduced on a cloth (hereinafter referred to as an ink-jet image) by an ink-jet printer or to increase the density, a water-soluble resin is applied to the surface of the cloth to form an ink. A method of preventing bleeding to the surroundings or smoothing the surface of the fabric with the water-soluble resin to eliminate the variation in the amount of ink adhered has been adopted.

[0003]

However, the prior art,
It aims to make inkjet images as sharp as conventional offset or gravure printed images or photographic images, and has an artistic value superior to conventional offset or gravure printed images or photographic images It does not render an image.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to reproduce an ink jet image which has a deeper color, has a three-dimensional effect, and is artistically valuable on fabric, as compared with offset or gravure printed images and photographic images. And

[0005]

That is, the ink-jet cloth 17 according to the present invention comprises the ink-jet cloth main body 11.
A powder 16 granulated by fibers 13, inorganic fine powder 14, and binder 15 is spray-bonded to the surface of the adhesive 12 applied to the surface of the substrate. It is preferable to use pulp fiber for the fiber 13 and calcium carbonate or diatomaceous earth for the inorganic fine powder 14.

[0006]

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, ink ejected from a nozzle of an ink jet printer is a powder 1
The gap 18 between the powder 6 and the powder 16 hits the surface of the powder 16. The ink ejected between the powders 16 enters the gap 18 and does not rebound. Further, the ink ejected onto the surface of the granular material 16 has a curved surface whose surface is slightly inclined with respect to the ejection direction of the ink. Since adjacent particles are interposed in the direction, the repelled ink enters the gap 18 between the adjacent particles 16. The powder 16 is composed of the fiber 1
3 and a mixture of inorganic fine powder 14 and binder 15, on the surface of which is formed fine irregularities with some of the fibers protruding, and fibers 13 and fibers 13 are separated inside by inorganic fine powder 14. Fine gap 19
The ink jetted onto the surface of the powder 16 is absorbed by the fine irregularities on the surface, and is transmitted to the fiber from there, and is absorbed by the fine gap 19 inside. Further, the ink ejected to the surface of the powder 16 is urged in the ejection direction, and flows and diffuses in the ejection direction while being absorbed by the fine gaps 19 inside the powder 16 to be dispersed. Is coated over the entire surface. Thus, the ejected ink adheres to a very limited narrow portion corresponding to the particle diameter of the granular material 16 to which the tip of the nozzle of the printer faces, and does not bleed out around the same, so that the inkjet image is sharp. Will be reproduced.

As described above, the inorganic fine powder 14 is mixed so as to separate the fibers 13 from each other and to form fine gaps 19 therebetween. Therefore, the particle size of the inorganic fine powder 14 is as fine as possible to be equivalent to the thickness of the fiber 13, and generally 20 to 300 μm.
It is good to Inorganic fine powders 14 include those used as fillers for latex and other resin compositions such as calcium carbonate, zeolite, clay, talc, aluminum hydroxide, barium sulfate, magnesium carbonate, diatomaceous earth, cement, gypsum, etc. Can also be used. Among them, it is recommended that the inorganic fine powder 14 itself has a porous structure, such as diatomaceous earth. This is because the fine gaps 19 can be densely formed inside the granular material 16.

[0008] The length of the fibers 13 is also set to 10 times or less, generally 10 mm or less, preferably 5 mm or less of the particle size of the powder 16 in order to reduce the particle diameter of the powder 16. Preferred fibers are cellulosic fibers that have water absorbency and are easily compatible with the ink, and pulp fibers are particularly recommended. The pulp fibers may be crushed waste paper.

The binder 15 is used in such a small amount that the fiber 13 and the inorganic fine powder 14 are adhered to each other and the shape of the powder 16 is maintained. So that it is not blocked. The size of the powder 16 is generally 1 mm or less, preferably 300 μm or less, and the particle size varies depending on the use of the ink jet image. For those that can be seen from a relatively close distance, make them smaller.

The fibers 13 are intertwined with each other at a small amount to form a net-like three-dimensional structure, in which the inorganic fine powder 1 is contained.
4 are entangled and held, the fibers 13
The amount of the binder and the binder 15 used may be less than half of the volume of the inorganic fine powder 14 in volume ratio, and by doing so, the non-combustibility can be imparted to the ink-jet fabric 17. In order to increase the non-combustibility of the ink jet fabric 17, it is preferable to use aluminum hydroxide which contains water of crystallization and has a flameproofing effect.

It is preferable to apply a paint 20 on the spray-laminated surface of the powder 16 so as to prevent peeling and falling off. Further, in order to suppress the detachment and detachment of the powder 16, it is preferable to apply or not apply the paint 20, and to pass through the embossing roll to suppress the irregularities due to the powder 16, and to make the spraying lamination surface smooth. Even when the material passes through the embossing roll, the recesses (gap 18) between the granules 16 remain without disappearing, and the fibers 13 exposed on the surface guide the ink to the fine gap 19 inside. In addition, it is crushed by the embossing roll and the cracks 21 are finely formed on the surface of the granular material 16 and the ink is easily absorbed. Therefore, even if the surface is smoothed through the embossing roll, there is no inconvenience. Does not grow,
Inkjet fabric 1 with smooth surface and excellent wear resistance
Finished at 7.

As described above, the dough body 1 is formed by the granular material 16.
1 is imparted with ink absorbency. Therefore, the fabric body 11 includes not only a porous sheet such as paper or cloth (woven fabric or nonwoven fabric) having water absorption, but also a plastic film or metal sheet (thin metal plate or metal foil) which has not been conventionally used for ink jet. Other non-water absorbing sheets can also be used. In addition, even if the crack 21 is formed on the surface of the granular material 16 by passing through the embossing roll, the granular material 16 is not crushed finely because the fiber 13 is entangled.

A pulp fiber 13 having a length of about 2 to 5 mm, a calcium carbonate 14 having a particle size of about 50 μm, and a powder 16 having a particle size of about 350 μm granulated with an acrylic resin emulsion 15 are mixed with a carboxymethyl cellulose soda salt (C. MC), and the dough 17 obtained by spraying and laminating on the coated surface of a flame-retardant backing paper for wall covering having a basis weight of 98 g / m ² coated with the acrylic resin emulsion composition 12 thickened according to When the ink was applied through an ink jet printer for a personal computer, a printed material with clear images and a three-dimensional effect was obtained.

[0014]

As described above, according to the present invention, the ink absorbing property is imparted by the granules 16, so that the plastic film or the metal sheet is used for the fabric main body 11, and the inkjet fabric 17 having excellent water resistance is used. Can be obtained.

The ink ejected from the nozzles of the ink jet printer does not scatter on the surface of the cloth 17 and adheres to dots in a narrow place defined by the powder 16 facing the nozzles, so that the ink jet image is clearly reproduced. Is done.

The whole of the granular material 16 scattered and adhered to the fabric body 11 is covered with the ink, giving an appearance as if the ink was raised and applied, and the fine undulations (irregularities) due to the granular material 16 were observed on the surface. Therefore, it is possible to reproduce an inkjet image that has a deeper color, has a sharp outline, has a three-dimensional effect like an oil painting, and has an artistic value, as compared with an offset or gravure print image or a photographic image.

Since the powder 16 contains the non-combustible inorganic fine powder 14, a non-combustible ink-jet printed material suitable for interior and exterior materials can be obtained.
