Description

Thermoplastic upper

A multi-layer leather upper structure, in particular a thermoplastic upper layer multi-layer upper structure.

Since the No Sew process can reduce the human resources during manufacturing and processing, it can avoid the waste of materials due to the cutting, sewing or trimming process of the processing materials, so that the sewing process is gradually prosperous. Manufacturing industry such as footwear, garment industry or bag accessories.

At present, the non-sewing process is applied to the footwear industry mainly in the no-sewing process of the upper, and the thermoplastic polyurethane elastomer (TPU) material is the mainstream application material. The TPU has the advantages of thermoplasticity and can be sewn without sewing. In the process of hot pressing or plastic forming, it is widely used in running shoes or sports shoes and other uppers. It is designed with breathable mesh holes to make running shoes and sports shoes have the advantages of ventilation and light weight.

However, the current types of shoes that are not available on the market are mainly made of running shoes or sports shoes, lacking casual shoes or casual shoes, and the leather materials used in casual shoes or casual shoes are not hot-plastic. The characteristics cannot be applied to the no-sewing process, which limits the application of the no-sewing process.

In order to solve the current no-sewing process, it is mainly based on running shoes or sports shoes. Mainly, the lack of casual shoes application, and the main leather material of casual shoes can not be applied to the difficulty of the sewing process. The present invention provides a thermoplastic upper, which comprises a layer of leather layered and integrally formed into a shape of the upper, a heat A plastic layer and an inner layer.

Wherein two adhesive layers are respectively disposed between the leather layer and the thermoplastic layer and the thermoplastic layer and the inner layer to bond the leather layer and the thermoplastic layer with the thermoplastic layer and the inner layer.

Wherein, the thickness of the thermoplastic upper is between 9mm and 12mm.

Wherein, the thickness of the leather layer is between 2 mm and 3 mm.

Wherein, a texture is formed simultaneously on the leather layer and the thermoplastic layer.

With the above structural features, the present invention has the following advantages:

1. In order to improve the shortcomings of the current non-sewing process only for specific shoes such as running shoes or sports shoes, the present invention utilizes the characteristics of the thermoplastic layer to be molded and laminated, and then heat-pressed or blistered together. After the hot plastic layer is formed by hot pressing or plastic forming, the leather layer can form a vamp shape corresponding to the thermoplastic layer, and the leather material can not be applied to the shortcoming of the no-sewing process, and the comfort is made according to different foot shape appearances. Beautiful casual shoes.

2. The present invention utilizes a thermoplastic layer to heat the shape of the moldable shape, and further shapes a particular texture or pattern into the thermoplastic layer, and the leather layer corresponds to the texture or pattern of the thermoplastic layer on the upper surface. Together form a corresponding texture or pattern to increase visual aesthetics and texture.

Figure 1 is a schematic view showing the molding of the first preferred embodiment of the present invention.

Figure 2 is a perspective view of the first preferred embodiment of the present invention.

3 is a schematic view of a second preferred embodiment of the present invention applied to a casual shoe.

Referring to FIG. 1 to FIG. 2, the present invention is a thermoplastic upper 10. It is mainly applied to a casual shoe, which comprises a leather layer 111, a thermoplastic layer 113 and an inner layer 115. In this embodiment, the leather layer 111, the thermoplastic layer 113, and the inner layer 115 are cut into a predetermined shape and laminated by using a no-sewing process (No Sew), and then hot pressed or sucked by a mold 20. The plastic molding method is integrally formed into the thermoplastic upper 11 and the subsequent steps of no additional sewing are required to achieve the advantages of the simplified process. The thickness of the thermoplastic upper 11 varies depending on the demand, and the thickness is between about 9 mm and 12 mm, which is suitable for casual shoes of different sizes and shapes. Further, an adhesive layer 114 may be further disposed between the leather layer 111, the thermoplastic layer 113 and the inner layer 115, such that the leather layer 111 and the thermoplastic layer 113 and the thermoplastic layer 113 and the inner lining Layers 115 can be adhered to each other and secured for subsequent processing.

The material of the leather layer 111 is mainly leather, including animal leather leather, plastic artificial leather or real imitation mixed leather. The material of the leather can increase the overall beauty and texture of the casual shoes 10, and the leather is soft and elastic, which can enhance the wear. The comfort of the leather layer 111 is different for men's and women's shoes, the thickness of the men's shoes is about 3 mm, and the thickness of the women's shoes is about 2 mm; the thermoplastic layer 113 is the key to the main molding of the casual shoes 10, and thermoplastic polyurethane is optional. (TPU), thermoplastic elastomer (TPE/TPR), polyvinyl chloride (PVC) and other materials, which can be molded when heated, and fixed to the shape after molding after cooling, so that the leather layer can be made without plasticity. 111, because it is co-pressed with the thermoplastic layer 113, and the thermoplastic layer 11 is formed into a thermoplastic upper 11 of the casual shoe 10; the inner layer 113 is disposed on the inner side of the thermoplastic upper 11 The thermoplastic upper 11 contacts the user's foot The area of the skin is preferred because it has a fine and soft surface.

Referring to FIG. 3, the second preferred embodiment of the present invention further forms the thermoplastic upper 11 of the first preferred embodiment into a texture 112, and then is fixedly coupled with the large base 30 to form a complete one of the casual shoes. 10. Further, the pattern 112 is formed by providing a texture on the mold 20 in the first preferred embodiment, and the thermoplastic upper 1 of the first preferred embodiment is formed when the mold 20 having the texture is formed. The texture 112 can be formed on the leather layer 111 and the thermoplastic layer 113 to increase the visual appearance of the casual shoe 10. The novel change of the existing non-sewing process is only applied to specific shoe types such as running shoes or sports shoes, and the hot pressing of the leather layer 111, the thermoplastic layer 113 and the inner inner layer 115 is performed by the non-sewing process. Or the way of blistering, the leather layer 113 and the inner lining 115 which are not plastic-forming ability are formed into the thermoplastic upper 10. The seamless sewing process is successfully applied to the casual shoes, and the existing sewing process is broken. limit.
