2. Description of the Related Art

In general, a screen printing process is typically used to print patterns of various types on fabrics. Various designs, including letters, numbers, images, or real photos, are screen-printed, but are not limited to two-dimensional representations.

Therefore, technologies for stereoscopically displaying various types of designs on the surface of a fabric have been developed in recent years. The technologies mainly use a pop-screen printing method of stereoscopic pattern imaging of foams, a lamination method of stereoscopically displaying patterns by injecting and laminating the patterns by means of a 3D scanner or injection robot, or a PU casting method for stereoscopically displaying patterns by introducing liquid polyurethane (PU) into a mold.

More specifically, in the case of the pop-screen printing method, a foamed resin is applied to a cloth and dried by hot air or naturally at room temperature, and then heat is applied to the solid foamed resin to foam the resin to form a stereoscopic pattern as in Patent Document 1 discloses.

However, Patent Document 1 involves a problem in that the process is very complicated and the process time is very long.

Patent Document 1 is faced with a problem that, when a worker performs work by manually applying the foam to the cloth, a difference in the appearance of the design occurs depending on the capabilities of the worker, resulting in a difference in the quality of the finished fabric leads. In addition, there is a problem in that, when the resin is not completely foamed, a desired stereoscopic texture is completely displayed.

In addition, in the lamination method, a composition for forming a pattern from a nozzle is sprayed onto the surface and laminated using a device including an ignition mechanism, and the laminated composition is cured so as to form a three-dimensional part as disclosed in Patent Document 2 ,

However, Patent Document 2 is also faced with a problem because the injection and lamination time is long and the curing time of the stereoscopic illustrated pattern is very long, resulting in an extension of the entire process time.

In addition, in the case of the PPU casting method, a base layer and a resin are transferred into a mold shaped according to a desired pattern, and then the resin is removed from the mold and cured so as to form a stereoscopic pattern, as in Patent Document 3 disclosed.

However, Patent Document 3 is also faced with a problem because the curing time of the stereoscopic pattern is very long, resulting in an extension of the entire process time.

In order to solve the above-mentioned problems, the applicant of the present invention has filed an application of an invention entitled "Method of Forming Three-Dimensional Pattern using Adhesive Fabric" as Patent Document 4 (not published, granted on April 24, 2014).

More specifically, Patent Document 4 discloses that either a yarn coated with a hot melt resin or a yarn coated with a hot melt resin and a TPU ( thermoplastic polyurethane) yarn in the form of a knitted fabric with continuous holes in jersey weave is made to produce an adhesive, wherein the adhesive is laminated to a base material and the laminated adhesive by a simple surface molding process with a protruding part and a depressed portion, thereby forming a stereoscopic pattern and leading to a significant reduction in the number of processes and the process duration.

However, the patent document 4 is also faced with a problem that either the hot-melt resin or the yarn coated with a hot-melt resin and the TPU yarn are woven to express a plastic texture but not a textile texture, resulting in a Reduction of flexibility leads.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention for achieving the above-mentioned effects relates to a shoe midsole coated with an adhesive. In the meantime, in the detailed description and the accompanying drawings, a description and explanation of the construction and operation that a person skilled in the art can easily understand will be made briefly, or will be omitted to avoid redundancy. In particular, the illustration and explanation of the detailed engineering and operation of elements having no direct connection with the technical features of the present invention will be omitted, and only the technical constructions directly related to the present invention will be briefly illustrated and explained ,

Hereinafter, an adhesive material formed by circular knitting and a method of forming a three-dimensional pattern using the same according to the present invention will be described in detail with reference to the accompanying drawings.

First, a circular knit-shaped adhesive 20 according to the present invention configured such that a yarn coated with a hot melt resin 21 and a cloth yarn 22 be formed by circular knitting to form the adhesive, as in 1 (a) shown. The adhesive substance 20 formed by circular knitting includes an upper layer L1 that separates from the fabric yarn 22 is woven, and a lower layer L2, that of the hot-melt resin-coated yarn 21 is woven as in 1 (b) shown.

As used herein, the term "circular knitting" refers to a form of knitting in which a yarn of knitting needles is formed into annular layers to form a knit in a break-through manner, such that multiple layers (ie, multiple layers) in a single fabric which is already known in the art.

In other words, since the weave shape, the method and the device for forming a fabric by circular knitting, which are already known in various variants in the art, differ greatly from each other according to the purpose, design and the like of a particular fabric, they are not particularly limited. Although all weave shapes, methods, and devices known in the art can be applied to the present invention, the adhesive becomes 20 shaped so that the top layer L thereof is of the fabric yarn 22 is woven and the lower layer L2 thereof from the hot-melt resin-coated yarn 21 is woven as in 1 (b) in an embodiment of the present invention.

In the meantime, as in 2 shown, a hot melt resin 21d on the outer surface of a fabric yarn 21c that's from a core 21a and a serving 21b is applied in an amount of 0.05-0.3 g / m. When the application amount of the hot melt resin 21d is less than 0.05 g / m, the three-dimensional pattern will not be smoothly formed. If, however, the order quantity of the hot melt resin 21d Exceeds 0.3 g / m, an error will occur if the adhesive material 20 is formed by circular knitting because of the large amount of the hot melt resin 21d ,

In this case, a polyester yarn, a nylon yarn or a cotton yarn alone or a combination of two or more kinds thereof may be used as the cloth yarn 21c used in the hot melt resin coated yarn 21 and a polyester resin, a polyurethane resin, an acrylic resin, a polyimide resin, an ethylene vinyl acetate resin or a polyolefin resin may be used alone or a combination of two or more kinds thereof may be used as the hot melt resin 21d be used.

Herein can the hot melt resin 21d on the fabric yarn 21c regardless of the type of fabric yarn 21c be applied. However, if the fabric yarn 21c is the polyester yarn, preferably the polyester resin or the polyurethane resin is applied thereto, due to a fusion property between the cloth yarn 21c and the hot melt resin 21d through the coating. If the fabric yarn 21c is the nylon yarn, the acrylic resin or the polyimide resin is preferably applied thereto. If the fabric yarn 61c For example, when the cotton yarn is the ethylene vinyl acetate resin or the polyolefin resin is preferably applied thereto.

In addition, a polyester yarn, a nylon yarn or a cotton yarn may be applied alone or a combination of two or more kinds thereof may be used as a cloth yarn 22 used with the hot melt resin coated yarn 21 is woven by circular knitting.

Herein, the reason why the yarn of the adhesive formed by circular knitting is limited to the hot melt resin coated yarn and the fabric yarn is that when either only the hot melt resin coated yarn or the hot melt resin coated yarn and the TPU yarn is formed by circular knitting, a plastic texture but no textile texture is expressed, which also leads to a reduction in flexibility, since the yarn is melted and compressed during the surface molding and therefore the through holes of the adhesive are blocked, which the air permeability deteriorates.

In the meantime, the basic material 10 use different substances which are suitable for the purpose of use of a corresponding substance.

Next, a method of forming a three-dimensional pattern using a circular knit-shaped adhesive includes a step (S100) of laminating the circular-knit adhesive and a step (S200) of performing a surface-forming process as shown in FIG 3 shown, a.

The step S100 is a step in which the adherend formed by circular knitting 20 on the upper surface of a base material 10 , as in 4 is laminated, so that the lower layer L2, that of the hot-melt resin-coated yarn 21 in the adhesive substance 20 is woven with the base material 10 is connected.

The step S200 is a step in which the laminated adhesive 20 to a surface molding process to form the three-dimensional pattern. In step S200, the surface of the circular knit-formed adhesive becomes 20 at a temperature of 100-150 ° C and a pressure of 10-50 kg / cm ² for 10-30 seconds using a mold 30 on which an embossed part 30a is shaped, compressed (in this case, the configurations of the mold and the embossed part can be modified in various ways, depending on the design and shapes used in 5 only one exemplary embodiment, and the present invention is not limited to this embodiment) as shown in FIG 5 shown so that a protruding part 20a on an area of the adhesive 20 is formed, the embossed part 30a the mold 30 corresponds, and a depressed part 20b is on the remaining area (ie an area where the embossed part 30a not on the mold 30 shaped), the adhesive 20 shaped, extending from the protruding part 20a by compressing and melting the remaining area, thereby forming the three-dimensional pattern, as in 6 shown.

In the meantime, when the surface shape state is out of the above-specified range, the three-dimensional pattern is not smoothly formed.

Thus, according to the present invention, the yarn coated with a hot melt resin becomes 21 and the cloth yarn 22 interwoven by circular knitting to the adhesive substance 20 to form, with the upper layer L1 passing through the fabric yarn 22 is woven, and the lower layer L2 (ie, a bonding surface with the base material 10 connected) through the resin coated with a hot melt resin 21 is woven, shaped, so that the adhesive material 20 from the lower layer L2 (ie, a layer formed by the resin coated with a hot melt resin) even without a separate adhesive having a base 10 during the surface forming process, and wherein a textile texture, but not a plastic texture, from the top layer L1 (ie, a layer that is separate from the fabric yarn 22 woven), which improves flexibility and air permeability. Next is the adhesive substance 20 on the base material 10 laminated, and then the laminated adhesive with the protruding part 20a and the indented part 20b is formed by a simple surface molding process of forming a three-dimensional pattern to thereby form a stereoscopic pattern, resulting in a significant reduction in the number of processes and the process time and improving the abrasion resistance against the compressed part during surface molding.

As described above, it will be readily understood by those skilled in the art that while the shoe midsole coated with an adhesive according to the present invention has been described and illustrated in connection with certain exemplary embodiments with reference to the accompanying drawings, various modifications and changes can be made to the present invention within the technical idea and the scope of the present invention, which is defined in the claims.
