According to the present invention, various fabrics such as a logo, a pattern, and a character are partially embossed on various fabric fabrics such as clothes, bags, hats and shoes to provide a wide variety of designs by protruding the entire cloth fabric, The embossing operation is carried out by pressing the urethane and the PVC sheet on the front and back sides of the fabric, respectively, and then the protruded embossing shape is deformed in the washing process and the repetitive wearing over a long period of time So that the embossing can be maintained semi-permanently.

As shown in FIG. 1, the present invention includes a mold installation step S1, a shape cutting step S2, a fabric setting step S3, an embossing molding step S4 to emboss various shapes on the cloth fabric 20, And a product completion step (S5).

In the mold mounting step (S1), a mold having various shapes such as a logo, a pattern, and a letter is engraved on a high frequency adhesive machine to prepare an embossing operation.

The mold is used in the same conditions and methods when the urethane 10 cut and the urethane 10 cut on the fabric 20 are pressed against the PVC sheet 30.

In the shape cutting step S2, a polyurethane (PU) sheet is laminated on the upper side of the urethane material 10 and the urethane 10 is placed on the lower end of the metal mold provided in the high frequency adhesive, The mold is lowered at a pressing force of 15-20 Kg to cut the shape of the mold.

When the polyurethane (PU) sheet is laminated on the upper end of the urethane 10 in the above step, the urethane material other than the shape to be embossed after the shape cutting is easily removed, the urethane material having the shape to be embossed is cut well, This is to prevent the materials from tangling or pressing together.

The thickness of the urethane 10 cut in the above step is preferably 4-6 mm.

When the thickness is less than 4 mm, the height of embossing protruding is low, and the discrimination power is lowered. When the thickness is 6 mm or more, the fabric 20 is not harmonized.

However, depending on the characteristics of the fabric 20 and the product, the embossing operation may be performed at 6 mm or more.

In the fabric setting step S3, the polyurethane (PU) sheet is removed after raising the mold of the high frequency adhesive, and the remaining urethane except for the shape of the cut urethane 10 is assembled and the cut urethane 10 to be embossed And a step of laminating the fabric sheet 20, the PVC sheet 30 and the polyurethane (PU) sheet on the top.

When the fabric setting is completed as described above, the embossing molding step S4 is performed.

In the embossing forming step S4, a mold having a temperature of 120-160 DEG C mounted on the high frequency adapter is lowered at a pressing force of 15-20 Kg, and the urethane 10 cut by the same metal mold is pressed on the lower part of the fabric 20 And pressing the PVC sheet 30 on the upper part.

 The above-described PVC sheet 30 enables various colors to be applied, thereby improving the harmony and aesthetics of the fabric 20 with the design.

Lamination of the polyurethane (PU) sheet on the top of the PVC sheet 30 in the above step facilitates the removal of the PVC material other than the shape to be embossed after the cutting of the shape of the PVC material, and the PVC material of the shape to be embossed Is the same as the reason for the shape cutting step (S2) in order to prevent the PVC material from being tangled or pressed against each other.

The product completion step S5 is a step of removing the polyurethane (PU) sheet after the embossing step S4 and cutting the remaining PVC sheet except for the shape of the pressed PVC sheet 30, Can be produced.

The PVC sheet 30 is removed in the fabric setting step S3 as shown in FIG. 3, that is, the polyurethane (PU) sheet is stacked on the upper portion of the cut urethane 10, The embossing operation may be performed by pressing only the urethane 10 on the fabric 20 through the molding step S4 and the product finishing step S5.

The above-mentioned embossing operation allows the fabric 20 to protrude due to the urethane 10 pressed on the lower portion of the fabric 20, thereby providing another design and aesthetics.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. And such changes are within the scope of the claims.
