KR20160087070A - Ethylene Vinyl Acetate foaming shoes and coating method of fabric - Google Patents

Abstract

The present invention relates to a method for coating a fabric in an ethylene-vinyl acetate (EVA) foam shoes, which comprises the following steps: applying a liquid primer on a surface of the shoes and then drying the same thereafter; applying an adhesive on the coated film on which the liquid primer is applied; and spreading pile power on the coated film on which the adhesive is applied and then drying the same. According to the present invention, formation of a fabric coating layer on the EVA foam shoes creates a soft texture and makes an exterior of the shoes elegant and luxurious. In addition, a sweat absorbing function can bring outstanding wearability, and anti-slip properties can help prevent accidents.

Description

[0001] The present invention relates to a method for fabricating an EVA foamed shoe and a EVA foamed shoe,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an EVA foam footwear, and more particularly, to an EVA foam footwear and a shoe coating method which enable a sweater to be absorbed and prevented from slipping,

In general, the development of a variety of footwear has progressed in various forms through the development of materials.

Particularly, production of low-cost consumable shoes such as sandals and slippers using injection technology is actively performed so that shoes can be manufactured quickly through a simple production process.

EVA (Ethylene Vinyl Acetate), which is one of the ethylene copolymers, is mainly used as the material of the synthetic resin shoes manufactured using the injection technique as described above. This is because the EVA material has flexibility, impact absorbability, , Heat insulation, and warmth.

However, the EVA foam shoes of the prior art have a certain limit to make the appearance of the EVA material look good, and it is difficult to absorb sweat and slip easily.

An object of the present invention is to provide an EVA foam shoe and an EVA foam shoe fabrication method which can make the appearance of a shoe look good, has excellent sweat absorption rate, and can prevent slippage.

In order to solve the above-mentioned problems, the present invention intends to form an EVA foaming shoe and a fabric coating layer on the shoe surface.

The material of the fabric is made of any one of nylon, rayon, and polyester, and shoes are molded. A strap is provided on the outside of the shoe for wearing comfort and safety of the shoe. EVA < / RTI >

The EVA foam shoe according to the present invention is provided with a fabric coating layer so that it can feel soft touch, feel good sweat absorption, and feel comfort when walking without slippery.

The present invention has various types of straps to smoothly put on or take off shoes, and the emboss layer is formed on the bottom of the shoe, so that it is light, flexible and slippery, and can feel comfort when walking.

BRIEF DESCRIPTION OF THE DRAWINGS Fig.

The EVA foam shoe 100 according to the present invention not only can make the appearance of the EVA foam shoe 100 look good but also forms a cloth coat layer 101 on the shoe surface so as to absorb sweat and prevent slippage, And a strap 102 is provided on the outside.

Here, the fabric material may be any one of nylon, rayon, and polyester, and the fabric coating layer 101 may be formed on the entire inner or outer surface of the shoe.

The strap 102 can be sewn through a high-frequency press in order to effectively support the ankle. The strap 102 has a dual strap structure, which is opened at both right and left sides, .

The EVA foam shoes 100 according to the present invention can attach the rubber brush to the outer bottom surface of the shoe so as to prevent slippage, and the embossed layer can be formed by silicon screen printing the outer bottom surface of the shoe.

Normally, in the case of shoes, rubber soles can be attached, but in the case of shoes for infants and children, flexibility and light weight are required. Therefore, it is preferable to form embossed layers instead of rubber soles to satisfy these conditions and slip resistance.

The EVA foam shoes 100 according to the present invention can cut a part of the upper side of the shoe and sew the ultimate cloth 106 thereon. That is, the upper end of the EVA foam shoes 100 is cut and skimmed, and sewed with the fabric upper 106. In the EVA foam shoe 100 according to the present invention, an insole having a high hardness on the inner side where the inner side of the foot is located and a low hardness on the outer side where the outer side of the foot is located Can be inserted.

3 is a flowchart illustrating a process of coating a fabric on EVA foam shoes according to the present invention.

First, the shoe surface is coated with ultraviolet (UV) coating (S110), which is a method of coating a substrate using a coating material which is cured in a short time by irradiating ultraviolet rays. This step is a pre-treatment step for improving the adhesion of pile powder, rubber brush, etc., which is a post-work process.

Subsequently, the primer solution is coated on the UV coated coating film and dried (S120). This step is also a pre-treatment step, and the primer solution may contain an olefin resin having excellent properties of adhesion and workability and excellent elongation.

Subsequently, an adhesive is applied to the coating film coated with the primer solution (S130). At this time, the adhesive may be any one of natural rubber, synthetic rubber latex, polyvinyl acetate, and polyacrylic acid ester, and the same color as the pile powder applied in the following process may be used.

Finally, pile powder is coated on the coated film with the adhesive and dried with hot air at about 60 to 70 ° C

At this time, the pile powder may be any one of nylon, rayon, and polyester. In this process, the pile of shoe is adhered to the shoe surface by the adhesive applied on the shoe surface to form a flocking layer, that is, a monolayer. After that, if the unfixed pile powder is removed, the whole process is completed.

In the present invention, when the fabric is coated only on a part of the EVA foamed shoe, it is preferable that a mask is attached to the surface of the shoe which is not required to be coated before the application of the primer solution, The step of removing the mounted mask may further include removing the mounted mask.

Hereinafter, the operation of the present invention will be described.

When the EVA foam shoe according to the present invention is worn, it is possible to feel soft touch with a fabric coating layer, to feel sweat comfort, to feel comfort, and to feel a sense of stability when walking without slippery. Moreover, the appearance of the shoe is beautiful, and it is possible to feel the luxury when worn.

In addition, various types of straps can be provided to smoothly wear or take off shoes. In addition, the silicone screen prints the embossed layer on the bottom of the shoe, making it lightweight, flexible and slippery so you can feel comfortable when walking. Also,

The insole having different in- and outer-side hardness can be provided to prevent the toe-toe phenomenon that the foot moves inward when walking.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the invention is not limited to the disclosed exemplary embodiments, And various alternatives, modifications, and changes may be made within the scope of the present invention to those skilled in the art.
