DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink-jet fabric, and more particularly to an ink-jet fabric capable of producing a high-quality product with a delicate image and no stain on ink jet dyeing.

[0002]

2. Description of the Related Art Conventionally, screen printing, roller printing, rotary screen printing, transfer printing, and the like have been used as a method of printing a pattern on a cloth. It is necessary to prepare engraving rollers, transfer paper, and the like, and the production of these screen frames, engraving rollers, and transfer paper is quite expensive. It has the disadvantage that it cannot respond quickly to diversification of fashion.

In order to eliminate these drawbacks, a sample is read by a scanner, and image processing is performed by a computer.
A technique for printing the result by an ink jet method has been developed, and has recently been put to practical use in the paper field. This ink-jet system has attracted attention in the field of textiles since it can be produced without spending time and money, and attempts have been made to apply it to fabrics.

[0004] However, in order to obtain a delicate image in the ink jet system, it is necessary to move the object as close as possible to the ink jet nozzle so that the ink is not diffused. However, fabrics, especially short fibers (staples)
There is fluff on the surface of the fabric consisting of Aiba), when the ink jet nozzles as close to the fabric is to try not to diffuse, up to become thread stain occurs jet nozzle in contact with the fluff of the cloth It is necessary to perform printing by separating the ink jet nozzle more than the fluff length, and there is a problem that a delicate image cannot be obtained.
Further, there has been a problem that the ink adheres to the fluff due to the fluff of the fabric, does not reach the surface of the fabric, and whitening occurs.

[0005]

SUMMARY OF THE INVENTION The present inventors have conducted intensive studies on ink-jet fabrics, and as a result, by using a fabric having a specific fluff length and fluff density,
The inventors have found that all of the problems of the existing method can be solved, and have completed the present invention. SUMMARY OF THE INVENTION An object of the present invention is to provide an ink-jet fabric that can obtain a high-quality product having a delicate image, no stain, and no whitening.

[0006]

An object of the present invention is to provide a staple fiber.
(Staple fiber), wherein the fluff length on the surface of the fabric is 0.9 mm or less,
The fuzz density of a fuzz having a length of 5 to 0.9 mm is 15/10.
cm ² or less, and fluff fluff density of length of less than 0.5mm is achieved by an ink jet cloth, characterized in that at 30 lines / 10 cm ² or less.

Hereinafter, the present invention will be described in detail.

In the present invention, a fabric is a short fiber ( staple ).
Fabrics consisting of Le fibers), a knitted or nonwoven fabric, the fibers of cotton constituting them, hemp, natural fiber wool, acetate, semisynthetic fibers triacetate, polyester, nylon, synthetic fibers such as acrylic or Les
-Yeon .

The fluff length on the surface of such a fabric is 0.9 mm.
Or less, preferably 0.7 mm or less;
The fluff density of the fluff having a length of 9 mm is 15 pieces / 10 cm ² or less, preferably 10 pieces / 10 cm ² or less, and 0.5% or less.
The fuzz density of the fuzz having a length of less than 30 mm is 30 pieces / 10 cm ²
Below, it is necessary to set it preferably to 15 lines / 10 cm ² or less.

If the fluff length exceeds 0.9 mm,
The fuzz density of fuzz having a length of 0.5 to 0.9 mm is 15 /
When the fuzz density of the fluff having a length exceeding 10 cm ² or less than 0.5 mm exceeds 30/10 cm ² , thread is likely to be generated due to contact between the ink jet nozzle and the fluff of the fabric, and it is attempted to avoid the thread. Then, the ink jet nozzle cannot be brought close to the cloth, and a delicate image cannot be obtained.

In order to satisfy the above-mentioned fluff length and fluff density, a fluff-suppressing agent treatment, an enzyme weight-reducing treatment, a double-grilling treatment of a baking after preparation such as a baking and a scouring of a raw cloth, + A shaving treatment after preparation such as scouring, etc., is not limited thereto.

[0012] The above-mentioned fuzzing agent includes water-soluble polyester resin, polyvinyl alcohol, polyacrylic acid,
Casein, gelatin, paste for printing (starch, natural rubber, sodium alginate, ammonium alginate,
Water-soluble resins such as carboxymethyl cellulose, maleic acid, hydroxymethyl cellulose and derivatives thereof, and emulsion resins such as hydrophilic polyester resins and vinyl compound polymers (polyvinyl acetate, polyvinyl acrylate resin, polyvinyl methyl resin). Such a fluff binding agent may be applied to the fabric by a padding method, a spray method, a dipping method, a coating method, or the like, and may be used in combination with another pretreatment agent as needed. The amount of the fluff binding agent used is appropriately selected so as to satisfy the above-mentioned fluff length and fluff density.

For the above-mentioned enzyme weight reduction, a cellulase enzyme, which is a cellulolytic enzyme, and a protease enzyme, which is a protease, are used. Examples of the cellulase enzyme include those extracted from cells such as Coniosilium jibulus diella, Alpergillus oryzae, Fusarium moniliforme, Irbex lacteus, Trichoderma koningi, Trichoderma viride, Rhizopus ariss fischer, Aspergillus niger, and the like. Specifically, Cell Crust 1.5L, SP359 manufactured by Novo Industry Japan, Cellulase A manufactured by Amano Pharmaceutical Co., Ltd.
P, cellulase AP-3, cellulase T-AP2, cellulase T-AP4, cellulase T-AP6, Entilon CM-10, Entilon CM-20 manufactured by Rakuto Kasei Kogyo Co., Ltd.
L, Novatex TH-20L, and the like.

As protease enzymes, Aspergillus meles, Aspergillus oryzae, Basilis subtilis, Carica papaya, Pineapple cannelli,
Examples include those extracted from cells such as Rhizopus niveus, and specifically, protease O manufactured by Nagase Seikagaku Corporation.

[0015] Such enzyme weight loss is determined by the dipping method, pad-
What is necessary is just to be made to a cloth by a batch method, a pad-steam method, etc. The amount, temperature, time, pH, etc. of the enzyme reducing agent are appropriately selected according to the suitability of the enzyme so as to satisfy the fuzz length and the fuzz density described above.

In addition, the above-mentioned fluff burning is performed by a method such as a gas burner method or an electric heating method. Length and fluff density. In addition, shaving may be performed instead of the second baking.

The ink-jet fabric of the present invention is made into a product through an ink-jetting step, a coloring step, a soaping step, and a finishing step. In the ink jet process, a heating resistor element is embedded in the nozzle, the ink is boiled by the heat generated, and the ink is ejected by the pressure of the bubble. The bubble jet method applies an electric signal to the piezoelectric element and deforms it to excite the volume change of the ink chamber. The pulse jet method, in which the ink particles are ejected, the ink is continuously jetted under pressure from the nozzles that vibrate ultrasonically to form particles, and the particles are controlled to a charged amount. The recording is performed by a charge control method or the like. It is preferable to use three primary colors or three primary colors and a black dye. The type of the dye may be selected according to the fiber constituting the fabric, and any of a direct dye, a reactive dye, an acid dye, a cationic dye, and a disperse dye can be used.
