The present invention relates to an embroidery fabric which is formed by embroidering a part or a decorative material for various fabrics and embroidering the embroidery using a coating yarn coated with a thermoplastic polyurethane (TPU) resin on the core and heat- .

In general, products such as shoes, bags, wallets or various pouches are products having fashion sense according to the trend of the times, and various parts or ornaments are sewn and adhered to the body of fabric or synthetic resin fabric.

On the other hand, in the case of manufacturing the shoe among the above-mentioned products, for example, various parts (back stay, fore stay, toe cap) are stuck to the outside of the shoe upper fabric and then various kinds of ornaments Or a sewing process. In the case of products such as a bag or a purse, the shoes are manufactured through the same process as the shoe manufacturing process.

However, in the conventional shoes as described above, since various parts and ornaments are formed on the upper fabric, the production process is complicated and the production cost is increased, and the productivity is lowered. In addition, since the weight of the shoes is increased, There is a problem in that the product is not suitable for the trend of lightening.

In addition, there are many restrictions on materials, shapes, designs and colors such as various parts and ornaments, and further, there is a problem that the production efficiency such as production process, time and cost is very low when these parts and decorations are formed. In addition, the conventional method as described above has a problem that it can not be applied to a base fabric such as a leather or a water-repellent fabric having a significantly low adhesiveness.

Recently, techniques for bonding various parts or ornaments to various fabrics by means of a hot-melt film or the like have been developed. However, this has also led to problems such as waste of materials due to the manufacture of various parts and ornaments, There is a problem that the production efficiency is lowered and the shape, design and color of various parts or ornaments are not variously applied, and it is still difficult to apply to a fabric having low adhesiveness such as leather or water-repellent fabric .

Therefore, in recent years, techniques for forming various parts and ornaments by embroidery method have been actively developed. In related art, Patent Document 1 discloses a method of embedding an embroidery on an aqueous web made of polyvinyl alcohol, And dissolving in water to use the embroidery portion as various fabrics themselves (for example, a shoe upper). However, in the case of Patent Document 1, there is a problem in that the yarns of the embroidery portions in the process of dissolving the web can not be fixed or fixed to each other, and are scattered or the positions of the yarns are shifted, so that the desired embroidery pattern can not be formed.

In addition, there is an attempt to form various parts or ornaments on various fabrics such as a shoe upper using embroidery, but since most of the embroidery parts are not formed firmly, they are easily peeled off or disturbed from the base fabric, .

In addition, the embroidery portion is also easily changed in a deformed environment such as the base fabric is stretched or the like, so that the restoring force is insufficient and the dimensional stability is very poor.

In order to solve this problem, Patent Document 2 discloses a method of absorbing hot melt to a yarn or coating a hot melt adhesive on the outer surface of a yarn, and then heat-treating the embroidery by using the hot melt adhesive. In the case of Patent Document 2, The shape of the yarn (yarn shape) is not clear and the value of the product is deteriorated. Also, when the fabric is applied to a base fabric (for example, leather) weak in heat, the base fabric is easily damaged by the heat treatment.
