Description

Method for shaping and wearing upper by using resin

The invention relates to a method for shaping and wearing a shoe upper by using a resin, which is coated on a shoe upper with a thermoplastic resin, and can be shaped by infiltration and bonding with the upper.

According to the common consumer products on the market, such as shoes, purses, clothes, etc., in addition to the use of leather materials, the uppers of the shoes, in order to improve the style and appearance of the upper, also use mesh, non-woven, Weaving or knitting cloth to make the upper part, while mesh, non-woven fabric, woven or knitted fabric are all soft materials, so the wear resistance is poor, the hardness is low and it is not easy to shape, which is easy to cause the appearance to be not stiff. The upper wear rate is high, so the service life of the upper is short.

The inventor specializes in the development, manufacture and sale of viscose-related products. In view of the traditional materials such as woven fabric (PET), suede, plastic, etc., it is difficult to shape and make it stiff, so it is hard to think hard. The solution, and with its own professional and years of work experience, and after several trials, corrections and improvements, finally developed a thermoplastic resin (Polyester...) materials, using screen printing and general The coating method is combined with woven fabric (PET), suede or plastic, and can achieve the stiffening and setting effect of the upper after cooling by the characteristics of the thermoplastic resin, which can replace the need for the toe and heel in the traditional shoe. It is an ideal production method by using the rubber lining to protect the shape and protect the wear resistance.

The invention relates to a method for shaping and wearing a shoe upper by using a resin, the main point being that the shoe upper is prefabricated and cut and formed, wherein the material of the shoe upper is mesh cloth, non-woven cloth, woven or knitted cloth. These are all soft fabrics. Although the appearance is diversified and gorgeous, the surface hardness is poor and it is easily damaged by friction. Therefore, the present invention uses a thermoplastic resin (Polyester) as a kind of glue for making the upper, which coats the thermoplastic resin on the upper by screen printing and general coating (mesh, non-woven, woven or knitted fabric). ) and by the temperature bonding with it, After drying and cooling, the purpose of hardening is achieved. The woven thermoplastic resin of the present invention, by different temperature control (60 ° C ~ 120 ° C), the thermoplastic resin is softened by heating, and is shaped according to the desired part and shape, and can be shaped after cooling and has Stiff characteristics, and does not affect the original shoe design color design.

Secondly, the properties of the thermoplastic resin are adjusted according to the hardness requirements, and the purpose is to be comfortable to wear in order to achieve an appropriate hardness requirement.

As for the manufacturing process of the upper of the present invention, the manufacturing process is as follows:

1. Cutting and forming: cutting and forming the material into a shoe upper shape, the material is one of a mesh cloth, a non-woven fabric, a woven or a knitted fabric, or a combination thereof.

2, screen printing and general coating: Re-screen printing and general coating, the thermoplastic resin is coated on the shoe to be shaped.

3, activation stereotype: it uses different temperature control (60 ° C ~ 120 ° C) by demand, the thermoplastic resin is softened after heating, and the upper is shaped according to the required part and shape.

4. Cooling and solidification: After the thermoplastic resin is dried and cooled, it can be solidified to shape the upper.

The above-mentioned forming technology is the first in the industry for the use of shoe-making technology, because the traditional mesh, non-woven fabric, woven or knitted fabric is a soft material that cannot be shaped, and it is also made into a shoe upper, and of course it will be loose, and this The invention can use the original soft cloth-like material, by using screen printing and general coating, and the bonding property of the thermoplastic resin, so that the upper can be shaped and stiffened to enhance the wear resistance and effectively extend the upper. Service life.

Figure 1 is a block diagram showing the process of shaping the upper of the present invention.

First of all, the design focus of the present invention is pre-made and cut and formed on the upper, wherein the material of the upper is mesh, non-woven fabric, woven or knitted fabric, etc., these are soft fabrics, although the appearance The colors are varied and gorgeous, but the surface hardness is poor and easily damaged by friction. Therefore, the present invention uses a thermoplastic resin (Polyester) as a kind of adhesive on the upper surface, which is a thermoplastic resin, which is coated with a thermoplastic resin on a shoe to be shaped by screen printing and general coating. And by controlling the temperature between 60 ° C and 120 ° C, in the process, the thermoplastic resin is softened by heating, and can be uniformly covered on the upper surface, by the viscosity of the thermoplastic resin, The material of the upper (mesh, non-woven fabric, woven or knitted fabric) can be closely bonded, and the original soft fabric is gradually stiffened, and the upper can be shaped according to the manufacturing requirements.

Next, regarding the manufacturing process of the upper molding of the present invention, please refer to FIG. 1 , which is a block diagram of the manufacturing process of the shoe upper molding of the present invention, and the steps of the shaping are as follows:

1. Cutting and forming 1: The material is first cut into a shoe upper shape, and the material is a mesh cloth, a non-woven fabric, a woven or a knitted fabric, or a combination thereof.

2, screen printing and general coating2: Re-screen printing and general coating, the thermoplastic resin is coated on the shoe to be shaped.

3. Activation type 3: It uses different temperature control (60 ° C ~ 120 ° C) to make the thermoplastic resin soften after being heated, and the upper is shaped according to the desired part and shape.

4. Cooling and solidification 4: After the thermoplastic resin is dried and cooled, it can be solidified to shape the upper.

In addition, the characteristics of the thermoplastic resin are adjusted according to the hardness requirements (about 60 ° C ~ 120 ° C), in order to achieve a suitable hardness and comfortable to wear, especially the raw materials used in the present invention are all environmentally friendly materials, After being eliminated, it can be recycled or incinerated, and it will not pollute the environment at all. It is an environmentally friendly raw material.

In summary, the technology of the present invention is the first in the industry for the use of shoemaking technology, because the traditional mesh, non-woven fabric, woven or knitted fabric is a soft material that cannot be shaped, and it is also formed as a shoe upper, of course, The invention is capable of reinforcing the wear resistance of the material of the original soft cloth by bonding the thermoplastic resin to the upper and the bonding property of the thermoplastic resin to make the upper shape and stiffen. Effectively extending the service life of the upper is an ideal method for making the upper, and it is not found in the publication. It has already met the patent requirements of the invention and has filed a patent application according to law.
