Description

Hot melt adhesive film combination structure

The invention relates to a composite structure of a hot melt adhesive film, in particular to a plurality of fine holes arranged on the hot melt adhesive film for infiltrating the ink pattern, so as to facilitate the hot press bonding protective film on both sides of the hot melt adhesive film and The combined structure of the hot melt adhesive film of the substrate.

Press, sports shoes, casual shoes, etc., in addition to wearing comfort, in order to improve the aesthetics and value of the shoes, the shoes must also have a pattern on the upper, in order to increase the aesthetics of the shoes, in order to attract consumption Those who favor it, and achieve the benefits of improving the sales rate of shoes.

Traditional shoes, such as the pattern on the upper, are mainly sewn on the upper of the shoe, or directly printed on the upper with a pattern printed on the screen; however, as the cost of the artificial sewing increases, the pattern The pattern is sewn to the upper, and the production cost is too high. The screen printing is directly printed on the upper by the screen printing, and the pattern is not easily attached to the upper. Therefore, as shown in the fifth figure, the manufacturer has developed a decorative sheet (6) with a pattern to adhere to the upper, in order to improve the cost of the above-mentioned sewing and the difficulty in attaching the pattern to the upper. The decorative sheet body (6) is mainly produced by screen printing an ink pattern (62) on the surface of a film (61), and then coating the surface of the film (61) on which the ink pattern (62) is printed. The adhesive layer (63) is adhered to the surface of the film (61) by the adhesive layer (63) to prevent the ink pattern on the film (61) from being scraped off, and a hot melt is continued. Film (65) and the tool The film (61) having the ink pattern is sequentially disposed on a substrate (66), and then hot pressed by a hot pressing device to thermally activate the hot melt film (65), and the film having the ink pattern is used. (61) Bonding to the substrate (66), thereby completing the production of the decorative sheet (6).

According to the manufacturing process of the decorative sheet body (6), the decorative sheet body (1) is composed of at least a film material (61), an adhesive layer (63), a protective film (64), a hot melt adhesive film (65), and a base. The material consists of five layers: (66); however, the five layers are not only costly, but also the five layers are sequentially bonded, which is cumbersome and time consuming, especially for super glue. When the adhesive layer (63) such as an organic solvent or an aqueous glue is applied, volatile gas is volatilized, causing damage to the respiratory tract of the operator, and uneven coating is likely to occur, affecting the firmness of adhesion, and the adhesive overflows. Missing after drying, etc. Therefore, in view of the fact that the conventional decorative sheet body (63) still has many defects such as the above-mentioned complicated steps, high production cost, and weak adhesion between the layers, it is the manufacturing and design experience and knowledge of the related fields for many years. Accomplished, and through many ingenuity, research and development of the present invention.

The invention relates to a composite structure of a hot melt adhesive film, and the main purpose thereof is to provide a plurality of fine holes on the hot melt adhesive film for infiltrating the ink pattern, so as to facilitate hot pressing of the two side faces of the hot melt adhesive film. The combined structure of the adhesive protective film and the hot melt adhesive film of the substrate.

In order to achieve the above-mentioned object, the present inventors have studied the following composite structure of a hot melt adhesive film, which is mainly provided with a hot melt adhesive film which is a film body having a sheet shape and a thickness, and The film body is formed with a plurality of irregular pores from the inside and the outside, and a protective film is disposed on one end surface of the hot melt adhesive film, and the hot melt adhesive film is provided with ink on the other end surface of the protective film. a pattern, and the ink pattern is infiltrated into the hot melt adhesive film from the pores of the hot melt adhesive film, and a substrate is further disposed, so that the substrate is correspondingly disposed on the hot melt adhesive film. The other end surface of the protective film is disposed, and the hot melt adhesive film is thermally bonded to the protective film and the substrate disposed on the both end faces thereof, and the pores of the hot melt adhesive film are adhered.

The combination structure of the hot melt adhesive film as described above, wherein the plurality of fine pores of the hot melt adhesive film include a film penetrating through the film body and not penetrating the film body.

Therefore, when the hot melt adhesive film of the present invention is combined with the protective film and the substrate, the plurality of irregular pores are provided on the hot melt adhesive film so that the ink pattern printed thereon is heated by the heat. After the pores of the molten film penetrate into the hot melt adhesive film, the hot melt adhesive film can be firmly bonded to the protective film and the substrate disposed on the two sides thereof to form a decorative sheet having a pattern, thereby being effective Simplify the number of layers and processes that make up the decorative sheet, and achieve substantial benefits such as material cost savings and manufacturing hours.
