Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable to polypropylene scraps, other plastic scraps, and scraps other than plastic scraps. By using the non-woven fabric obtained by blending it as a rod material, it has excellent elasticity, oil resistance, heat resistance, water resistance, moisture absorption, and moisture release properties, and has high dry flexibility and is resistant to punching. etc. characteristics? This relates to a method for manufacturing machine products, mainly insoles.

The present invention will be explained in detail below.

Is the 9th grade fabric used as a bag material? A non-painted cloth made by uniformly combining 6r'? use.

Polypropylene Recycled Hair Acrylic Recycled Polyester Recycled Wool Miscellaneous Recycle @1 As shown in the figure, the above non-uniform fabric (1) having a thickness of about 13111 was placed in a hot air dryer and the polypropylene groove melting degree was approximately 170°C. After heating to ~210°C, compressor with roll or press compresses to 50 Kp/an''~20
Rapid cooling while compressing with a pressure of 0 fine/cm', I! 2. As shown in the figure, a flat plate (2) with a thickness of about 3 m is formed, sometimes a suitably matched offshore curved plate.

*No binder is required when heating the fabric +1) because the polypropylene melts and is uniformly fused to the other fabric. Also, by changing the blending ratio of polypropylene waste, a plate material having any hardness can be formed.

By the above manufacturing method, a plate material having the following characteristics, for example, can be obtained.

Hardness 90-95 Soukoku: No electrical equipment broken after 10,000 to 30,000 cycles Pushing force: 22-28 damage/wound.

The plate material obtained by the above manufacturing method is t-, W
It can be used for materials and other purposes, but when used for the insole of shoes, it is cut by applying a cutting die with a shape to the outline 1 of the insole of the shoe to one piece of material. Incidentally, the non-woven fabric (1) may be placed in a female mold for forming the inner sole and heated, and then cooled while being compressed with a male mold.

The insole of the shoe is the insole (as shown in Figure 3 and [1t4).
Glue the inside material (4) such as press board on the bottom surface of 31 from the area near the toe to the area near the hoof 11F++
At the same time, the s part has a heel core made of wood etc.
51 After attaching the tiff, it is hung on the shoe cover.

Therefore, the present invention focuses on adhesion of the midsole (4) and heel core (5).
Eliminates the hassle required for installation. Me, middle school 11(3) and
The non-woven fabric (1) is placed in a female mold in which the inner material (4) and the heel core (5) are integrally molded, heated to approximately 170°C to 200°C, and then compressed with a male mold. By rapid cooling, the inner sole with a midsole and heel core (61
This also includes integral molding.

In addition, when using the board manufactured by the present invention as the insole of shoes, compression of the non-woven fabric (1), especially fine mesh on the surface of the teaching material? After laying a stainless steel mesh with
FIIL, the surface of the board is sometimes given a mesh-like uneven pattern, and the inner sole is made by adding a deodorizing agent to the non-woven fabric +11 or inserting copper wire that has an odor effect and a bactericidal effect. In some cases, the board material or insole of the material may be formed.

The present invention is based on the above 11! Not limited to examples but 0
For example, non-woven fabrics made of the following formulations of each type of fabric may be heated at the melting temperature of the plastic reaction contained in each fabric, and then cooled while being compressed to form a sheet.

Formulation example 1 (melting temperature 215°C to 220°C) Nylon wool stripes 1 Example 2 (melting temperature 1250°C to 260°C) Nylon 66
Recycled wool blend-13 (melting temperature 350°C) Phenolic fiber wool blending example 4 (melting! If 350°C) Fluorine-based green miscellaneous wool 1 example 5 (molten water It 350°C) Fluorine-based fiber-fed glass fiber blending example 6 (Molten water [255° C. to 260° C.) Polyester recycled wool cotton In addition, in Blending Examples 3 to 5, plate products that also have flame resistance are obtained.

Since the present invention is constructed as described above, it is made of inexpensive resin material and has elasticity, oil resistance, heat resistance, water resistance, 9 moisture properties, and moisture release properties C:
A board product with excellent properties such as high flexibility, high C2, and strong resistance to punching can be obtained, and the manufacturing process is simple.
A large amount of raw material 1 can be produced. Also, an insole formed from a plate material manufactured by the method of the present invention or an insole manufactured by the present invention.

The nails hold well during the process of hanging onto the shoe cover.
Since it does not bend even when subjected to pressure during the hanging process, troubles during the shoe making process can be prevented. In addition, in the layer of safety work shoes and other shoes made using the above-mentioned insole, there is no wrinkles in the areas where the fibers are concentrated in the insole, or the fibers loosen and swell. This has the advantage that even if water from drops seeps into the shoes, there is no chance of the courtyard becoming wet, and the original strength is maintained for a long period of time.
