Hereinafter, with reference to the accompanying drawings, it will be described in more detail as an embodiment with respect to the configuration and fabrication of a composite composite for leather according to the present invention.

In order to obtain products of various designs in response to trends in which the graphic-oriented expression desire of consumers has been increased, the present invention, as shown in FIG. 1, first of all the various graphics 10 created by the computer 10 are inkjet due diligence. By outputting to the real-time output machine 11 to the original fabric 12, an actual optical fabric including various first designs is obtained.

As shown in FIG. 1, the actual output printer 11, the material 12, and the ink 13 used in the present invention are currently widely supplied by various manufacturers at home and abroad, and are widely used in real business fields such as banner production. Known general and universal product. In particular, the present invention adopts a piezo output method using a solvent ink, and as a digital real-time output device, it supports more than 6 colors (13) of CMYK (Cyan Magenta Yellow Black) + Or. (Orange) + Gr. (Green). It is possible to express intense and primary colors, and it uses a real-time output machine that can express various designs with excellent color.

The digital inkjet actual output machine 11 is divided into a thermal method and a piezo method in the output method, and the characteristics of the material and the ink are different depending on the output method, but in the present embodiment, the piezo method is used. To print it out. In addition, the solvent ink 13 used in the present embodiment is also called a solvent ink, and the main components of the solvent in the solvent ink include esters and ketone solvents. It accounts for 60 ~ 70%.

In the above, the piezo method is a method using a piezo-electric device that generates electricity when a certain pressure is applied. The piezo method uses a crystal oscillation force of the piezoelectric device to spray liquid ink, and the piezo method uses solvent ink. In the case of using (13), since the ink does not adhere to the surface of the material after printing, it penetrates into the material depth and is completely adsorbed, so that improved results can be obtained in terms of durability of the printed design. Use) to output the actual fabric in a piezo fashion.

In addition, the inkjet yarn fabric 12 used in the present invention is a known digital printing fabric paper that can be directly inspected and transferred by coating and chemically treating a fabric such as nylon, polyester, or cotton, and has excellent fastness to the printed design. Of course, it is possible to minimize the bleeding phenomenon of the output design, and to obtain excellent color and waterproof effect.

In the above, the present invention is preferably 150 denier of both the warp yarn and the weft yarn in consideration of durability and texture, considering the characteristics of the coating chemicals and the properties of the ink, fabric price, fabric cutting ease, etc. T / P fabric made of 100% polyester is suitable. This is because the T / P fabric has excellent surface absorbency among various yarns, and it does not spread out and has excellent water resistance and durability even without a separate coating. Since the T / P fabric has a weakness in durability or strength of its back side, it can be maximized by supplementing it with a base fabric described later. In addition, in the case of output using a solvent-only material coated with a top resin by mixing PVC resin (resin), such as the T / P fabric of the embodiment of the present invention described above, the problem that the ink penetrates deeply into the material to spread the ink It has the advantage of being eliminated.

The fabric which outputs clear photorealistic images through the above method is a material having color development and waterproofing in itself, but the composite fabric for leather has a certain limitation in terms of durability and texture. In order to satisfy this, as described below, the base material of the present invention is to have a three-layer structure shown in FIG.

The top 14 of the urethane resin 20, which is often used for fashion items, has a cool feeling, leather touch, and gloss on the printed matter 14 of the inkjet yarn fabricated by the computer, and is waterproof, water repellent, It has properties such as water resistance, antifouling property, abrasion resistance, flex resistance, surface smoothness, weather resistance and cushioning property, and also gives a leather-like appearance.

The coating is melted between a pair of rollers in such a manner that the urethane resin 20 is melted and pressed between the hot calcined metal calender rolls 21a and 21b and coated onto a sheet as shown in FIG. 2. The urethane resin is pulled out in the form of a thin film (mm) and transferred to the next pair of rollers, thereby coating the yarn. Although there is no particular limitation on the thickness of the coating film, in the present invention, the thickness of the coating film is preferably adjusted to 0.1 mm to 0.2 mm so as to fully utilize the physical properties having high surface smoothness and cushioning properties.

As described above, the urethane film topcoated fabric 23 has a two-layer structure, which functions as a coated composite fabric, but furthermore, to be a fabric having a suitable strength capable of structural molding such as handbags, fashion bags, and sundries. The base fabric 30 is combined to have a three-layer structure to facilitate workability.

By combining the base fabric 30, the yarn yarn coated with urethane resin is endowed with the final shape stability, aesthetics, and functionality necessary to be commercialized as a composite fabric for leather. The base fabric to be bonded can be used in various fabrics according to the use such as synthetic leather or nonwoven fabric without any particular limitation, but the present invention is easy to process and PVC sponge, which is a material that blocks air permeation of a closed cell structure Artificial leather (PVC SPONGE LEATHER (30)) was used as the base fabric. This is because the PVC sponge artificial leather is not for clothing or upper but for sundries, it is preferable that air permeation is not only blocked, but also has a function and design characteristics. However, it is obvious that there is no particular limitation on the material of the base fabric adhered in order to appropriately use the designed fabric for various uses.

In other words, the PVC sponge artificial leather (PVC SPONGE LEATHER 30) is used to reflect the design characteristics of the product derived from the product planning stage based on various factors, such as functionality, practicality, aesthetics, which is a surface similar to leather Manufactured to obtain the characteristics, it is made into a sponge-like form by inserting pores in the resin for the purpose of reducing the change of flexibility due to texture or Chinese character. In addition, the base fabric can obtain various physical properties such as soft and hard, depending on the composition ratio of the plasticizer, excellent durability, and low price. In addition, the PVC sponge artificial leather (SPONGE LEATHER (30)) has a porous structure inside, excellent in flexibility and feel, and has properties such as good thermal insulation, restoring force, chemical safety, flame retardancy and water resistance. However, since the internal pores are hermetic, air permeability and dimensional stability are low, and there are many changes in physical properties over time. And the thickness of the PVC sponge artificial leather is preferably 0.6mm to 2.4mm, it is preferable to change in various ways depending on the use.

Adhesive coating and bonding method for bonding the base fabric 30 to the coated yarn is different depending on the thickness, flexibility, softness and rigidity of the fabric, so that the commercialized method is appropriately applied to the fabric However, in the present invention, considering that the fabric 40 of the PVC sponge artificial leather used as the base fabric is a fabric such as polyester 14, which is a yarn, the adhesive is commercially available adhesive bonds 41a and 41b. ) Is applied to each fabric bonding surface to bond the fabrics under the pressure of the rollers 31a and 31b. However, when the base fabric is different, the adhesive may be changed in various ways depending on the material.

Mechanical bonding method such as urethane film bonding method may be used, but in this design, because of the design characteristics of the product, a thick 2.1mm PVC sponge artificial leather (30) is used as a base fabric, so that it is wound around the appropriate length (Feeding) In this case, it is preferable to cut the PVC sponge artificial leather 30 directly in a pattern and adhere to the urethane-coated yarn, which is cut separately, that is, after cutting.

In the present embodiment, the base fabric 30 and the thread of the yarn yarn 23 to be bonded are made, respectively, and after the adhesive bonds 41a and 41b are applied to the respective adhesive surfaces, the method is bonded by the pressure of the rollers 31a and 31b. Since the use of the cutting and bonding of the base fabric 30 and the yarn fabric 23 for each pattern is a hassle, but this method can make the design differentiation by making the adhesion neat, preferential It can be referred to as the adhesive method in consideration of the adhesive strength.

If the thickness of the base fabric 30 does not have a problem in the feeding (feeding) or adhesive strength, since the mechanical bonding can be performed at a time by the urethane-coated yarn and the film bonding method, the adhesion can be simplified. Suitable base fabric thicknesses of less than 1.5 mm are suitable for this method. However, even if the cut is glued at one time, in the processing of high-quality leather products, the edges are generally cut and finished with a seam allowance, so if the fabric is thick, it is necessary to cut the edges to an appropriate thickness.

The pattern of the product is applied differently according to the design and the edge of the urethane-coated yarn (23) is cut in consideration of seam allowance, and then bonded with the base fabric (30) cut without seam allowance so that the edge seam cover wraps the base fabric. It can be finished by stitching and the base fabric can be cut a little so that the edge is not too thick.

Shapes of fashion products that can be molded into the base material according to the present invention is divided into a planar structure and a three-dimensional structure, the planar structure 53 is a cut fabric made to the last step, as shown in Figure 5 (a), the edge Finishing is completed by a method such as bias taping processing 50 or the like. As shown in FIG. 8, the flat structure product may be applied to interior wall ornaments, other book covers, belts, accessories, and the like. In addition, the product of the three-dimensional structure, as shown in Figure 5 (b) and Figure 5 (c), depending on whether the shape of the side plate is a quadrangle 51 or a semi-circular (52), the product shape may be different and Figure 5 ( The square shape as shown in b) is a hexahedral shape 54 of a general square pattern for producing a product by stitching the bottom edge of the side plate by rolling the three-dimensional foundation 55, and the semicircular shape 52 shown in FIG. Since the bottom surface is a rolling form 57, the product can be naturally formed only by the characteristics of the fabric, thereby obtaining a product having a very unique design sensitivity. The three-dimensional product may be utilized as a handbag, a fashion bag, or a storage basket as illustrated in FIGS. 6 and 7, and the planar shape may be used as an interior wall decoration as illustrated in FIG. 8.
