DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] like Figure 1-Figure 5 As shown, this embodiment provides a seamless seam upper with hot-melt splicing, including an outer protective surface 1 and a mesh surface 2. An adhesive tape 3 is provided at the bottom of the outer protective surface 1. In actual use, the outer protective surface 1 is bonded to the sole and the upper through the adhesive tape 3, and can also be further reinforced by stitching. After being connected with the sole and the upper, the outer protective surface 1 is located at the bottom, and can form a relatively stable surrounding structure around the user's foot. The mesh surface 2 is located at the top to increase the air permeability of the shoe body. The outer protective surface 1 and the mesh surface 2 are sutured and connected by hot-melt seams. In the actual preparation process, the outer protective surface 1 and the mesh surface 2 are cut into the required size, sewn together by seams, and then coated with reinforced plastic at the connection point. At the same time, the seams can be melted by high temperature, so that the connection of the upper There are no protrusions at the seams, which achieves a better seamless seam effect and effectively improves the appearance of the upper and the wearing comfort. The outer protective surface 1 is specifically made of a waterproof and antibacterial multi-layer composite fabric. Compared with the existing uppers, the outer protective surface 1 in the present application not only has higher strength when in use, but also has certain waterproof and breathable properties. At the same time, it has certain antibacterial ability. During wearing, it can inhibit foot bacteria to a certain extent to prevent bacteria from growing rapidly and causing odor. The comfort and protection are good. The mesh surface 2 is specifically made of a double-layer composite fabric with an anti-scratch silk layer 201 on the surface.

The anti-ultraviolet fibers block ultraviolet rays, which can not only provide appropriate protection for the feet, but also protect the fabric located on the inner side of the double-effect protective layer 103 to prevent it from rapid aging, thereby increasing its service life to a certain extent.

[0030] The antibacterial fiber is specifically bamboo fiber, which has good antibacterial ability and is made of natural materials, so it is more environmentally friendly. The anti-ultraviolet fiber is specifically cotton and linen fiber. Both cotton and linen are natural fibers with good air permeability, strong moisture absorption, and are comfortable to wear. Anti-ultraviolet agents can be added during the preparation process.

[0031] The mesh surface 2 is composed of a breathable mesh layer 202 and a flexible layer 203. The flexible layer 203 is arranged on the inner side of the breathable mesh layer 202, and the anti-scratch silk layer 201 is arranged on the outer side of the breathable mesh layer 202. The breathable mesh layer 202 has high air permeability, and the internal flexible layer 203 is in direct contact with the foot, which can maintain better comfort.

[0032] The material of the anti-scratch silk layer 201 is polyester-cotton fabric, a blend of polyester and cotton. This fabric is not easy to be scratched and is full of elasticity. Since it contains cotton, it has good air permeability and moisture absorption, and is suitable for making clothing and household items. The material of the flexible layer 203 is pure cotton, which has high comfort and certain air permeability.
