The present invention relates to a method of forming an embossed pattern on a mesh-type fabric paper used as a blind fabric, and more particularly, after weaving a mesh-type fabric paper having a predetermined light transmittance with a synthetic yarn coated with a thermoplastic resin, After heating to a temperature, orthogonal synthetic yarns are fused together, and then passed through an embossed roller having a predetermined uneven pattern, the thermoplastic resin coated on the synthetic yarn is melted and pressurized at a predetermined pressure to decorate a mark or logo of a company. The present invention relates to a method for forming an embossed pattern on a mesh type textile paper forming an embossed pattern of the present invention, and a blind fabric obtained therefrom.

In general, windows of banks and offices are equipped with various types of blinds for shading and privacy protection. For example, FIG. 1 is a perspective view illustrating an example of a roll screen blind, and includes a frame 11 attached to a wall or a ceiling, a gear box 12 provided at both ends of the frame 11, and a gear box 12. The chain 13 to be installed, the upper roller 14 which rotates in the pulling direction of the chain 13, and fixed to the upper roller 14 is wound up or unrolled in the pulling direction of the chain 13 to cover the window It consists of the screen 15 which becomes.

The blind fabric used as the screen 15 may be classified into a blackout type that completely blocks the external light and a semi-transmissive part that partially blocks the external light. The semi-transmissive type, which blocks the view from the inside while blocking, is mainly used. As the semi-transmissive blind fabric, a mesh type textile paper having a light transmittance of 3% or more is used.

On the other hand, the screen 15 is not only used as a means of shading but also used as an element of the interior design that can produce the indoor atmosphere beautifully, in recent years by printing a pattern or a picture of various shapes on the screen of the blind personality It has a beautiful and beautiful indoor atmosphere. However, most of them use a printing method such as live-action or silk-screen printing or by fusion of sheets printed with pictures or patterns, so that the flat pictures or patterns are expressed, which does not match the atmosphere of a bank or office. When the back is separated or detached and exposed to sunlight for a long time, not only the color changes but also the printed picture or pattern overlaps or shifts when the screen is retracted or folded.

Accordingly, the present invention forms a visual three-dimensional embossed pattern on the mesh-type fabric used as a roll screen or vertical blind fabric to match the bank or office atmosphere and not separated or detached during washing, but also exposed to sunlight for a long time It relates to a blind fabric that does not change color even if.

That is, a technique for forming an embossed pattern to enhance the aesthetic effect on paper, leather, vinyl paper, wallpaper, textile fabrics, etc. is well known, but there is no known technique for forming an embossed pattern on a mesh type fabric used as a fabric for a blade. In other words, the mesh fabric used for the blinds has not only a plurality of openings formed in the fabric to have a predetermined light transmittance, but also on one side or both sides of the mesh fabric to maintain a certain degree of stiffness and to have good durability, heat retention, and washability. Since a predetermined synthetic resin is coated, the embossing method applied to conventional paper, leather, or the like could not be applied to a mesh type textile paper having a plurality of openings.

The present invention has been made to solve these problems of the prior art, the main object of the present invention is to weave a synthetic yarn coated with a thermoplastic resin to form an embossed pattern on the mesh-type fabric paper to make a mesh-type fabric paper, irregular pattern on the outer peripheral surface Is formed and heated to a predetermined temperature to melt and pressurize the thermoplastic resin coated on the synthetic yarn to seal the openings uniformly formed in the mesh-type textile paper with the molten thermoplastic resin to correspond to the uneven pattern. It is to provide a method for forming an embossed pattern.

In addition, the present invention by partially sealing the opening of the mesh-type fabric paper by the molten thermoplastic resin to cut the mesh-shaped fabric paper with the embossed pattern of a predetermined shape to a predetermined size to use as a yarn for blades, such as minor tissue defects and contamination This prevents the entire fabric from being disposed of due to defects, which not only wastes resources, but also greatly improves the productivity of the fabric, and makes it possible to avoid decorative patterns or damages without complicated and expensive processes such as due diligence, silkscreen printing and film fusion. It can express the mark or logo of a company, and when it is installed on a window, the embossed pattern such as the mark or the logo is clearly displayed due to the difference in light transmittance, thereby providing a roll screen or vertical blind fabric that can enhance aesthetic and advertising effects.

Method for forming an embossed pattern on the mesh-type fabric paper according to the present invention in order to achieve the above object, the step of coating a thermoplastic resin, such as FB, blood oil, synthetic yarns, such as nylon, polyester, and the thermoplastic resin Weaving the coated synthetic yarn into a mesh type textile paper having a predetermined light transmittance, and heating the mesh type textile paper to a predetermined temperature to fuse the orthogonal synthetic yarns using a molten thermoplastic resin to each other; Pass the type textile paper between the embossed rollers with the irregularities formed on the outer circumferential surface to melt the thermoplastic resin coated on the synthetic yarn and press it at a predetermined pressure to seal the opening formed between the synthetic yarns to seal the embossed pattern of the predetermined shape. It comprises a step of forming.

The blind fabric using the embossed patterned mesh fabric according to the present invention is a mesh fabric woven from a synthetic yarn coated with a thermoplastic resin, wherein the thermoplastic resin is coated on the synthetic yarn on one side of the mesh fabric. Is melted and compressed to include an embossed pattern of a predetermined shape in which an opening formed between the synthetic yarns of the mesh type textile paper is partially sealed.

Hereinafter, a method of forming an embossed pattern on a mesh-type fabric paper according to the present invention and a blind fabric obtained therefrom will be described in detail with reference to the accompanying drawings.

First, Figure 2 is a perspective view schematically showing a blind fabric embossed pattern formed in accordance with the present invention, Figure 3 is an enlarged photograph showing a blind fabric embossed pattern formed in accordance with the present invention. As shown, the blind fabric 20 is a mesh-like fabric woven from synthetic yarn 22, such as nylon, polyester coated with a predetermined thickness of the thermoplastic resin 21, such as FB, blood oil, A part of the plurality of openings 25 formed in the original fabric forms the embossed pattern 30 having a predetermined shape by melting and compressing the thermoplastic resin coated on the surface of the synthetic yarn 22.

As described above, the embossed pattern 30 formed in the blind fabric 20 according to the present invention is formed by partially closing the opening 25 of the mesh fabric, so that the window of the blind is installed in the closed opening 25. The difference in the light transmittance between the embossed pattern 30 formed by the embossed pattern 30 and the base portion formed by the open opening 25 is large, so that the embossed pattern 30 is clearly displayed. Therefore, when the mark or logo of the enterprise on the blind fabric installed in the bank or office is represented by the embossed pattern 30 according to the present invention, the mark of the enterprise formed on the screen of the blind due to the difference in the transmittance of light entering through the window The logo is clearly displayed, which is very effective in enhancing the corporate image.

In addition, since the decorative pattern represented on the screen forms a shadow pattern on the floor or the wall according to the direction of sunlight, it can produce a very unique and beautiful indoor atmosphere. In addition, the embossed pattern 30 engraved in the mesh-like fabric is softly expressed in the same color as its bark color, so that when the screen is wound or folded, the light is not transmitted and the embossed pattern is not visually expressed, thus providing a visually clean and stable feeling. Given.

At this time, openings of a predetermined size are formed between the synthetic yarns to weave to have a light transmittance of a certain degree. For example, the light transmittance of the mesh type textile paper is preferably woven in the range of 3% to 30%.

Subsequently, the mesh type textile paper is heated to a predetermined temperature to melt and then harden the thermoplastic resin coated on the synthetic yarn so that the orthogonal synthetic yarns are fused to each other (300). Therefore, the openings formed between the synthetic yarns are fixed to a predetermined size by the thermoplastic resin. Then, the mesh fabric is manufactured so as to pass through the embossed roller having a predetermined uneven pattern to form an embossed pattern (400). Therefore, the thermoplastic resin which is in contact with the concave-convex pattern of the embossed roller is melted and pressed at a predetermined pressure to close the opening, thereby forming an embossed pattern corresponding to the concave-convex pattern. Finally, a predetermined cut of the mesh-shaped fabric paper with embossed patterns is formed into a roll screen or vertical blind fabric. 500 If necessary, before the embossed pattern forming step 400, a dyeing process or a surface treatment process is performed. It may be further included.

In this way, the blind fabric formed in accordance with the present invention is not only the opening of the mesh-like fabric is fixed by the thermoplastic resin, but also the embossed pattern is not deformed because the opening forming the embossed pattern is closed by the thermoplastic resin. In addition, the thermoplastic resin is coated to maintain a certain degree of stiffness, not to twist or warp, as well as excellent durability, thermal insulation, chemical resistance and washability. In addition, the blind fabric according to the present invention, when installing a blind screen formed with various types of decorative patterns or corporate marks or logos on the window, the decorative pattern or marks made of closed openings are clearly expressed by the difference in light transmittance. The visual effect is excellent.
