Hereinafter, the present invention will be described in detail for each embodiment with reference to the description. Denim washing method according to a first embodiment of the present invention, the steps of preparing an embossed plate having a pattern to be formed at a predetermined position of the denim material is embossed, and placing the denim material on the embossed plate, and the upper part of the embossed plate Including the step of forming a pattern by grinding the denim material using an abrasive member. In the embossed plate, the pattern to be formed on the denim material is embossed in the polishing step. As long as the embossed plate has enough hardness and strength to support the denim material in the polishing step, it may be made of various materials, for example, it may be made of wood or metal. Here, when the embossed plate is made of a soft material, the denim material can flow during friction with the abrasive member, so the pattern is softly expressed. On the other hand, when the embossed plate is made of a hard material, the denim material flows Because it is limited, there is a characteristic that the pattern is expressed clearly. Therefore, it can be prepared by freely adjusting the hardness of the embossed plate according to the type of pattern to be formed. On the other hand, of course, the pattern formed of the embossed plate can be produced in various patterns as needed. In addition, the embossed plate may be provided as a flat plate, but since it is provided in a cylindrical shape in the case of denim, that is, the trouser end of jeans, the embossed plate may also be provided in a cylindrical shape. The embossed plate is provided with a plurality of different areas of the protrusions protruding in response to the pattern, and can be polished by sequentially replacing the embossed plates with the smaller areas of the protrusions. That is, in the case of repeatedly polishing by replacing the embossed plate with a narrow end area of the protrusion first, then gradually replacing the embossed plate with a large protrusion area, the central part of the pattern is repeated and the polishing is performed. It becomes a lot, and the washing becomes less toward the outer side of the pattern. Therefore, by making the washing density of the pattern to form a layer, it is possible to improve the naturalness of the pattern. Here, the material, pattern, and shape of the embossed plate described above can be equally applied to the engraved plate to be described later. In the step of forming the pattern using the abrasive member, a certain portion of the denim material protruding by the protrusion of the embossed plate is discolored while the abrasive member is repeatedly rubbed and washed. Here, the abrasive member may be provided in various types, for example, may be provided with a brush, sandpaper, or a tile having irregularities formed on the surface. For example, when the abrasive member is provided with a brush, it is moved up and down or moved left and right while being rubbed with the denim material to cause discoloration. At this time, when the abrasive member provided with the brush is moved up and down, when the polishing is performed, there is less wear or damage to the denim material and the dye is discolored, so there is an advantage of a more natural pattern than when polishing while moving forward or backward or left and right. . On the other hand, when the abrasive member is provided with sandpaper, washing is performed while moving forward, backward, left and right. Here, the step of forming the pattern using the abrasive member may be performed in a water tank containing water heated to a set temperature range of the denim material. That is, when the polishing operation is performed in water, the fibers of the denim material are in a relaxed state unlike in the air, so that the polishing conditions by the abrasive member are more advantageous, and the water performs the same function as a solvent to decolorize the dye. This makes washing much easier and also prevents wear and tear on the denim material. Here, the temperature of the water contained in the water tank may be variously set as needed. On the other hand, the embossed plate may include the step of heating to a set temperature range. This reduces the degree of wear of the denim material by reducing the number of times of polishing the abrasive member to achieve the same washing level by creating conditions for the dye to be easily discolored, as in the above-mentioned polishing in heated water. , so that a natural pattern is formed. Here, a solvent that promotes washing may be applied to a portion of the denim material corresponding to the pattern.

The engraved plate is formed as an opening with a pattern to be formed on the denim material in the polishing step. The engraved plate may be provided with a plurality of bars having various sizes of openings, similar to the embossed plate described above, so that the size of the opening is gradually changed from a small one to a large one while being polished. As a result, the central portion of the pattern has a large number of polishing times, so washing is performed, and as the number of polishing decreases toward the periphery, washing is reduced and a gradation effect can be exhibited. Here, when the embossed plate or the engraved plate is provided in plurality, all may be provided in plurality, but only the engraved plate may be provided in plurality. On the other hand, it may include the step of heating one or more of the embossed plate or the engraved plate to a set temperature range. Here, a solvent that promotes washing may be applied to a portion of the denim material corresponding to the pattern. In this embodiment as well, as in the first embodiment described above, the polishing operation may be performed in a water tank containing water heated to a set temperature. Denim washing method according to the third embodiment of the present invention, characterized in that the washing is made using only the intaglio plate. Accordingly, the denim washing method according to the third embodiment includes the steps of preparing an engraving plate having an opening having a pattern to be formed at a predetermined position of the denim material, locating the denim material under the engraving plate, and the engraving plate and polishing the denim material using an abrasive member on the upper part of the to form a pattern.
