[0003]

SUMMARY OF THE INVENTION In view of such technical background, the present invention is to provide a resin-processed fabric having a three-dimensional pattern excellent in aesthetics and design.

[0004]

The present invention employs the following means in order to solve the above problems. That is, the resin-processed fabric having a three-dimensional pattern of the present invention is characterized in that at least the resin coating on the surface of the resin-processed fabric is ground in a pattern.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, since the patterns of conventional resin processed products are lacking in aesthetics and designability, when it was earnestly studied whether or not a novel three-dimensional pattern could be imparted, the resin processed fabric By buffing the surface of the machine with a buffing machine and grinding it, it was surprisingly discovered that a novel patterning that was not possible in the past can be applied.

The three-dimensional pattern referred to in the present invention means that the surface is removed depending on the degree of grinding and the pattern is formed in a recessed state as compared with the surroundings. The resin coating may be a single layer or a laminated coating, and each layer may be a differently colored resin coating or a differently colored resin coating in the plane direction. If the resin coating is colored differently for each layer, the color of each layer appears by grinding and a more three-dimensional pattern can be formed.

The base of the cloth used in the present invention may be either a non-woven fabric or a woven or knitted cloth, and the cloth may be a raised product or a cut pile product. A raised product is a product in which fibers on the surface are fluffed by a buff, a needle cloth, a thistle or the like. The cut pile product is a double pile weave, a double pile knitted product, or a loop knitted product, which is formed into a napped fabric by pile cutting or shirring.

The fiber material constituting such a cloth is not particularly limited, but natural fibers composed of plant fibers such as cotton and hemp and animal fibers such as wool, silk and leather. Regenerated fiber consisting of cellulosic, semi-synthetic fiber,
Synthetic fibers such as synthetic fibers made of polyester, polyamide, polyacrylonitrile, polyethylene, polyvinyl chloride and the like can be used. Further, low melting point elastic fibers such as polyester elastomer, polyurethane elastomer, polyisoprene and polybutadiene, resins may be mixed and used.

When a fabric is coated, the coating resin, the film forming method, the coating method, etc. differ depending on the material of the fabric and the purpose of the functionality. It is a product with unique characteristics.

The surface coating resin film of the cloth is made of polyurethane, vinyl chloride, acrylic, amino acid, chloroprene, or a mixture thereof, and contains inorganic materials such as metal oxides and calcium compounds in the resin. An organic substance such as a fluorine-based water repellent or a silicone resin may be added, or a dye or a pigment may be added to the resin for coloring. Further, as a film forming method, there are a dry method, a wet method, a hot melt method, a latex method and the like, and a coating method includes a method using a reverse roll coater, a gravure roll coater, a knife coater, a roll doctor, etc. It may be appropriately used in the present invention.

Coloring of the surface of the fabric includes printing using a dye color paste on a flat screen or a rotary screen, and a method of coating a dye or a pigment using a gravure roll coater. You can use it.

The present invention relates to a cloth product in which a resin film on the surface of the cloth product is buffed in a pattern by a buffing machine and the resin film of the cloth product or the cloth product is made into a three-dimensional pattern by the degree of grinding. A buffing machine is a machine that grinds with an abrasive, and as the abrasive, sandpaper, which is generally called a paper file, is mainly used.The sandpaper is sanded by moving the sandpaper in a certain direction or reciprocating. Touch the paper and grind. A general buffing machine has a structure for buffing the contact between the cloth and the sandpaper via a linear support in the width direction called a bed. The degree of polishing is determined by the sand particle size of the sandpaper, the relative speed of the sandpaper and the cloth, the contact pressure, the contact time, and the like. The patterning is performed by contacting the fabric partially or entirely and fluffing and removing the resin coating of the fabric or the fabric.
Depending on the degree of cutting, the surface morphology may differ due to differences in the non-contact area or contact conditions, resulting in a three-dimensional pattern. As a patterning method, it is necessary to control partial contact with sandpaper and contact conditions. In the case of computer control, the bed pressed against the sandpaper is divided into several millimeters in the width direction, and each element is independently moved up and down by computer instruction. The vertical movement distance can also be controlled by a computer and the degree of grinding can be adjusted. As a patterning method other than computer control, a flexible support with an uneven pattern is attached to the back side of the fabric and passed through a buff machine to give an uneven pattern pattern that is the reverse of the uneven pattern, or the edge of the bed edge. For example, a method of giving a vertical stripe pattern by processing unevenness and passing a fabric through it, a mechanically moving the bed up and down to provide a discontinuous linear pattern, and reciprocating left and right to give a vertical wavy pattern Can be used.

The pattern referred to in the present invention means a pattern, a symbol, a figure, a character and the like. By applying a pattern, it is possible to impart or identify aesthetic and design properties, transmit information, and partially adjust the adhesive strength and frictional resistance.

For patterning a conventional coated fabric, a transfer method using a release paper in which a pattern is preliminarily engraved in the manufacturing process, a method of impressing an uneven pattern on the resin coating surface with an embossing roll, etc. have been proposed. However, in each method, the pattern showed the surface condition of the same material, was not interesting, and had little change. On the other hand, although the patterning by color on the fabric is mainly the printing at present, it is necessary to raise the pattern on the screen, which is a problem in terms of cost in processing a small lot.

In the present invention, since the resin-processed fabric is directly ground by using a buff machine, it can be performed in a shorter time than the conventional method.
It is also an attractive method in terms of cost because it can process small lots.

Further, the grinding pattern by the buff is an unprecedented one, and when the resin layer is completely removed by the buff to expose the base cloth portion, a more contrasting pattern can be formed. A buffing of the resin layer, which is particularly microporous, gives a nubuck-like pattern with a deep tint. In addition, with a resin-processed fabric in which the resin layer is colored differently with a laminated coating of two or more layers, it is possible to form a colorful and even more aesthetic three-dimensional pattern.

The present invention will be described in more detail with reference to the drawings. The patterned fabric according to the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 indicates a nonwoven fabric artificial leather base fabric made of the polyester ultrafine fibers and polyurethane polymer obtained according to the present invention, and wet-coagulated with polyurethane. In the cloth made of the resin coating obtained by the method, the portion 2 is a portion which is not buffed and is generally called a silver surface. The part 3 is a pattern part consisting of a nubuck-like part in which the surface of the resin film is ground by partially buffing the part 2 by buffing, and it is clear due to the unprecedented pattern form and the reflection and absorption of light. A three-dimensional pattern appears.

Next, the buffing machine used in the present invention will be described. FIG. 2 is a schematic side view of the buffing machine, and FIG. 3 is a schematic front view of the buffing machine showing a state in which no cloth is hung. The endless sandpaper 4 rotates at a constant speed and grinds the napped fabric 1 via a bed 5 composed of elements divided in the width direction in units of several millimeters. As for the operation of the elements, each element is operated up and down independently through the air cylinder according to the instruction of the computer which inputs the pattern in advance. The operating distance can also be adjusted, and the amount of grinding in the strongly pressed part will increase and the change will be clearly seen,
In addition, the weakly pressed portion is in a blurred state because the amount of grinding is small. This makes it possible to draw more realistic designs. In addition, adjustment of grinding amount and fluffing state
It can also be carried out by the grain size and material of the sand of the sandpaper, the speed of the sandpaper and the relative speed of the cloth, and the rotating direction of the sandpaper.
