Description

Digitalized method for printing shape of shoe capable of large production}

The present invention relates to a digital fabric transfer method of the shoe uppers capable of mass production of the pattern of the shoes, more specifically, to produce a large quantity of fiber fabrics inscribed with a predetermined pattern, mass production of the patterned shoe uppers It is possible to provide a digital transfer method of the textile fabric of the shoe upper can be made possible, to prevent water pollution and air pollution, and to reproduce the sophisticated and complex color design.

In general, a pattern having various shapes of colors is expressed on a surface of various materials such as clothing, cloth, advertising banners, glass, and iron doors. In the related art, the glyph is composed of simple screen printing, and in the screen printing, the work has to be performed several times depending on the number of colors to be expressed. However, in recent years, since this operation can be performed more simply by a method of thermal transfer using heat and pressure, it is widely used.

Thermal transfer basically uses heat as a medium to form images or letters to be produced using a transfer ink on a transfer paper, and then places the transfer paper on a fabric or transfer object (glass, iron plate, tile, cup, wood, etc.). After applying heat and pressure, the transfer ink is printed on the transfer object. Unlike the screen printing described above, such a transfer may be performed in a single operation, and thus, the transfer may be performed.

In particular, the printing technology that prints designs and drawings on the desired fabric fabric using sublimation, which is a physical or chemical phenomenon, is called "Sublimation Warrior." That is, sublimation transfer is a fiber transfer technique in which solidified ink particles printed on paper vaporize at a proper heat and pressure to penetrate into a fabric and print.

Currently, the transfer machine is mainly used as a plate transfer machine and a roll transfer machine. The flat plate transfer machine places the transfer object on the lower plate, places the transfer object transfer paper, and heat-compresses the upper plate to transfer the transfer ink to the upper surface of the transfer object. The roll transfer machine is installed so as to rotate the electric heating pressure roller in the center portion by the power, and transfers the transfer object and the transfer paper between the pressure rollers.

The temperature used for the transfer in the flat plate type transfer machine or roll transfer machine as described above is about 180 ℃ to 220 ℃, for this purpose is to use a plate coil-shaped heating wire.

This sublimation transfer has been mainly applied to cheap textile manufacturing parts such as quilts and curtains, and recently, it is also applied to the footwear industry by the demand of buyers who want colorful designs and colors.

Shoes usually consist of a sole and an upper coupled to the top of the sole. The sole consists of an outsole that forms the sole of the shoe and a midsole that usually forms the sole of the shoe. The outsole is made of rubber material to satisfy the functions for wear resistance and slippage, and the midsole is mainly made of foamed and expanded synthetic resin material to absorb the impact and restore the rest when the shoes are light and shocked. .

The upper is a part that forms most of the outer appearance of the shoe, and the outer surface of the upper is provided with various patterns, brand level, etc., thereby increasing the beauty of the shoe.

The upper is made of a leather material or a variety of functional fiber fabrics as raw materials, and the upper, which is formed with various patterns, is cut into a shape that can surround a person's foot and is coupled to the upper part of the sole.

1 is a development of the pattern forming apparatus of the fiber fabric according to the general method. As shown in this figure, in order to form a pattern on the surface of the fiber fabric, the desired pattern 5 must be formed in the mold 10 and the fiber fabric 20 is pressed against the mold 10 at high pressure and high pressure. . In this case, the mold 10 itself is expensive and excessively expensive, as well as an average of 10 days or more to produce a mold with a desired pattern is time-consuming. In addition, in order to form a pattern on the mold, press the fiber fabric on the mold, and press the fiber fabric to form a pattern on the fabric fabric, the pattern itself formed on the mold must have a certain depth. Therefore, there is a problem that it is difficult to form a fine pattern on the fiber fabric. In addition, since the fabric is pressed after heating the fabric at a high temperature, there is also a problem that the pattern is blurred after the process is finished.

On the other hand, a more various pattern forming method is applied to the fiber fabric. In other words, because of the characteristics of the fiber fabric can be wound in the form of a roll, a method of forming a pattern on the artificial leather by using the embossing roller to continuously press the fiber fabric. However, in the method of continuously forming a pattern using such a roller, the manufacturing cost of the roller itself is excessive. In addition, cowhide or pig leather and the fiber fabric is limited in the area of the product and there is a problem that can not be used in the form of a scroll according to mass production pattern printing method using a roller.

In addition, conventionally, a pattern was formed on the transfer paper by using an offset method, a gravure method, and a rotary press.

The process of forming a pattern on the transfer paper in the above manner is approximately as follows.

That is, after printing a graphic on a printing film, the printed film is corroded to form a printed pattern on the copper plate, and then colorized. Then, a printing job is performed on the transfer paper.

However, the above gravure printing or offset printing causes water pollution, air pollution, the working environment becomes dirty, and it is difficult to reproduce complex color designs.

Recently, a method of improving such a problem has been widely used.

That is, the graphic transfer paper 40 and the fiber fabric 50 having a pattern formed on the press 60 are superimposed on each other, and the graphic transfer paper 40 and the fiber fabric 50 are simultaneously pressed to thereby form a patterned fiber fabric ( 50) A lot of methods are used.

The above-described method will be described in more detail as follows.

In order to form a pattern on the graphic transfer paper 40, a predetermined pattern is first designed by using graphic software by a computer or the like.

When the designed pattern is output through the printer (graphical printer), the original plate of the pattern is made.

By the way, conventionally, one printer is connected to one computer main body, and a method of outputting a sheet of transfer paper is mainly used. However, by this output method, since a large quantity of the same transfer paper and fiber fabric cannot be mass-produced, there is a problem that it is difficult to mass produce the upper of the shoe and even the shoe.

In addition, as described above, the conventional sublimation transfer method is a process of transferring using gravure printing or offset printing, which is caused by problems of water pollution and air pollution of raw materials, uncleanness of working environment, and difficulty in reproducing fine and complicated color designs. It has been pointed out that there are many limitations.

Therefore, an object of the present invention, it is possible to produce a large amount of fiber fabrics inscribed with a predetermined pattern, it is possible to mass-produce the patterned shoe uppers, consistent and precise printing, accurate color and design reproduction is possible It is to provide a pattern forming method of the shoe to be.

In addition, another object of the present invention is to provide a method of forming a pattern of shoes that can prevent water pollution and air pollution, and to reproduce a sophisticated and complex color design.
