Description

Surface treatment method for sole with hollow structure

The present invention relates to a surface treatment method for a sole having a hollow structure, and more particularly to a method for forming a coating layer and a protective layer on the surface of an article having a hollow structure by a technique of water transfer printing.

In today's scientific process, in order to make the appearance of the product more changeable and textured, the surface treatment of the transfer technology is usually applied to the surface of the product to make the product more competitive.

Traditionally, the color of the sole of a generally transparent or translucent hollow structure has been changed, usually by painting or dyeing.

There are many ways to form a color pattern on the surface of the product so that the product has a beautiful color. Generally, traditional printing or painting, in the face of complex products, such as car dashboards, steering wheels, computer housing kits, mobile phones, mouse and other electronic products, glasses, rackets and other daily-use boutiques, often only No help.

However, water transfer can not only cope with such problems, but also transfer the color pattern through water transfer printing technology, and is more suitable for products having different materials. Moreover, since the pattern and color of the water transfer are vivid, the added value of the product can be greatly improved.

The feature of water transfer printing technology is that it can be used for products with quite complicated shapes. Furthermore, water transfer The range of materials that can be applied to the technology is also quite wide, such as plastic, metal, glass and ceramics, which can be applied to the surface of the product by water transfer.

The surface treatment method of the present invention utilizes a water transfer technique to utilize a shrinkage effect caused by drying of a fine surface on which a coating surface is stretched on the surface of a flexible or translucent transparent or semi-transparent hollow structure sole. The method of forming a tiny pit to form a vivid color and a transparent texture. Another object of the present invention is to provide a method for attaching a film layer to an article, instead of changing the color and pattern of a generally transparent or translucent hollow structure sole by means of painting or dyeing, and imparting a three-dimensional printing effect to the product. With intricate patterns and colors, it has more heavy and diverse visual effects, and its pattern film and the manufacturing process attached to the article use only the general activation solvent, so there is no problem of treating air pollution and dye wastewater. It can greatly reduce the pollution and harm to the environment.

Please refer to both Figure 1 and Figure 2. 1 is a flow chart showing a surface treatment method in accordance with a preferred embodiment of the present invention.

Figure 2 is a schematic illustration of a surface treatment method embodying the present invention with ink transferred to a surface of a hollow-structured sole object via selective masking of a predefined surface.

The surface treatment method of the present invention can be used to treat a hollow structure sole surface with embossing and to treat the article by selectively shielding a pre-defined surface, which may be a midsole or a combination of a midsole and an outsole. First, in step 102, a method of surface treatment of the article of the present invention is started. Then, in step 104, a step of wetting and diffusing the coating is performed. That is, a portion of the film 209 coated with a coating such as the ink 211 is immersed in a container 205 containing a liquid such as water 207, and the film 209 is floated on the water 207.

Generally, before the film 209 is placed in water, the ink 211 attached to the film 209 is activated with an activator, and then the film 209 is placed in water, and the activator acts to soften the ink 211 and The film 209 is immersed in water to cause a diffusion effect, and the ink 211 can be separated from the film 209.

Next, in step 106, a transfer step is performed. That is, the object 201 having the hollow structure sole is immersed in the water 207 of the container 205, and the ink 211 is uniformly transferred onto the surface 203 of the object by the hydraulic pressure of the water 207, so that a coating layer is formed on the surface 203 of the object. And the cover layer is covered On the concave and convex lines of the object surface 203, the surface of the object surface 203 has a color pattern to be transferred.

Thereafter, in step 108, the step of washing is performed. The object is washed with water so that the excess ink 211 remaining on the surface 203 of the object is removed to wash the surface of the object 201.

Then, in step 110, the step of drying and forming a pit on the ink surface is performed. Then, after drying the object 201, in step 112, a step of applying a protective layer is performed to form a protective layer over the coating layer and penetrate the ink surface pit to further adhere to the object surface 203, except for preventing the ink 211 from the object. The surface 203 is detached, and the ink on the surface 203 of the object has a light transmitting effect. The step of applying the protective layer can also be completed at least once, or more than one time by spraying and drying.

Please refer to FIG. 3 , which is a schematic diagram of the surface 203 of the object 201 having the concave and convex lines, and the ink 211 and the protective layer 301 are sequentially transferred. At this point, the product can present a completely different visual effect. The material of the protective layer may be a transparent paint, and the transparent paint may be a PU glue or a UV glue. Finally, in step 114, the method of surface treatment of the article of the present invention is terminated.

In the above steps 104 and 106, that is, in the step of performing the wetting and diffusion of the coating and the step of performing the transfer, the method can be carried out in an automated manner, and on the other hand, it can also be manually divided. The segment is implemented, and in the actual commercial production operation, all or any of the steps of the present invention can be implemented by means of automation of the mechanical structure design or by manual operation.

Please refer to FIG. 4 , which is a schematic view showing the surface of the object with a hollow structure sole provided with a shielding jig in the surface treatment method of the present invention.

Referring to the fifth figure, in the surface treatment method of the present invention, a schematic diagram of a completed product of the surface of the object provided with the hollow structure sole is applied.

Referring to the sixth figure, in the surface treatment method of the present invention, the surface of the object having the hollow structure sole is provided, after the water transfer step is completed, drying is performed to form an ink surface pit, and then the step of applying the protective layer is performed. The flow diagram is formed by forming a protective layer over the coating layer and penetrating the ink surface pit to further adhere to the object surface 203.

It can be seen from the above that the water transfer technology can impart different visual qualities to different products (such as wood, stone, fabric, leather) and different colors, and the pothole effect caused by ink diffusion can make the surface of the product have good. Transparent texture and touch. Therefore, the product produced by the surface treatment method of the present invention can have the visual impression of the product which is water-transferred at the same time, and the firmness of the adhesion of the ink to the surface of the product, and the visual effect of the transparency of the product can be expressed. . Therefore, the surface treatment method of the present invention enables the manufactured product to have the advantages of the product manufactured by the water transfer and dyeing technology. The product can have a new appearance value, which greatly enhances the added value of the product.

In the above, the present invention has been disclosed in the above embodiments, and is not intended to limit the present invention, and various modifications and refinements may be made without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
