[0002] Shoes are a kind of clothing accessories whose task is to protect and wrap the feet of the user. They are basically composed of a sole and an upper. The sole is the lower part that contacts the ground, and the upper is the upper part arranged on the sole. The upper can wrap the user's feet and be connected to the sole to fix the sole on the user's feet to prevent the sole from falling off. The setting of the upper can effectively improve the integrity of the shoe and the foot, and make the shoe's protective effect on the foot and the cold-proof effect better.

[0003] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: when the wearer performs high-intensity multi-directional sports, the wearer's feet often generate strong lateral forces on the shoe upper, and the shoe upper will be repeatedly torn. After a period of use, it is easy to cause the shoe upper to become loose or even damaged due to repeated tearing, making it difficult to stably hold the foot, thereby reducing the overall wrapping and strength of the shoe upper and shortening its service life. When wearing the shoe upper for high-intensity sports, it is easy for the foot to protrude too much from the shoe upper, resulting in sports injuries such as sprains, and safety cannot be guaranteed.

[0013] A further improvement is that: the outer surface of the hollow yarn is also hot-melt-connected with a TPU outer film layer.

[0014] To achieve the above object, the present invention may also adopt the following technical solution: A method for manufacturing a tear-resistant upper, comprising the following steps: Step 1: fix two first transverse yarns in a braiding machine, and bend the yarns to form a sinking V-yarn and a floating V-yarn, sew and fix the top two ends of the sinking V-yarn under the first first transverse yarn, sew and fix the top two ends of the floating V-yarn to the first first transverse yarn through the braiding machine, sew the bottom of the sinking V-yarn upward on the second first transverse yarn, and sew the bottom of the floating V-yarn downward on the second first transverse yarn to form a first braiding unit, and combine multiple first braiding units to form a shoe upper body; Step 2: fix the second transverse yarn and the third transverse yarn in a braiding machine, and use the braiding machine to float and weave the first longitudinal yarn in the middle section of the second transverse yarn, sink and weave the second longitudinal yarn in the middle section of the second transverse yarn, and make the first longitudinal yarn and the second longitudinal yarn cross between the second transverse yarn and the third transverse yarn to form a first cross knot, then sink the first longitudinal yarn and weave it into the middle section of the third transverse yarn, and float the second longitudinal yarn and weave it into the middle section of the third transverse yarn to form a second braiding unit, and combine multiple second braiding units to form a reinforcement body; Step 3: fix the upper TPU yarn layer and the lower TPU yarn layer in the braiding machine respectively, and fix the vertical yarn of high-strength polyethylene yarn material between the upper TPU yarn layer and the lower TPU yarn layer through the hot melt component of the braiding machine, and then weave the floating horizontal yarn and the sinking horizontal yarn into the middle section of the vertical yarn to form a third braiding unit, and combine multiple third braiding units to form an edge body; Step 4: Sew a connection reinforcement body on the upper body at the forefoot position, sew an edge body on the edge of the upper body and reinforce the connection edge body by hot-melt to obtain a finished upper.

[0017] The present invention provides an edge body on the edge of the upper body. By weaving a plurality of vertical yarns and upper and lower TPU yarn layers into floating horizontal yarns and sinking horizontal yarns, the weaving density of the edge of the upper body is high, thereby greatly improving the strength of the edge of the upper body, making it less likely to crack at the edge of the upper body. In addition, the high-strength inflated horizontal yarns are used to improve the heat dissipation performance and greatly reduce the weight. While ensuring the strength of the edge, the shoe is made lighter. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, a reinforcing body 12 can also be formed at the forefoot position and the heel position of the vamp main body 11, and the second transverse yarn 121 and the third transverse yarn 122 interlaced with each other by the reinforcing body 12 are arranged The first longitudinal yarn 123 and the second longitudinal yarn 124 are combined to form a prismatic woven structure passed by the second transverse yarn 121 and the third transverse yarn 122, on which the first cross knot 126, the second cross knot 125 and the third cross knot 127 are formed. The second transverse yarn 121, the third transverse yarn 122, the first longitudinal yarn 123 and the second longitudinal yarn 121 are tightly hinged together through the three cross knots, which not only improves their support performance, but also greatly improves their anti-pulling performance. When applied to the forefoot position, it can provide the forefoot of the foot with better anti-trampling ability, and at the same time, the forefoot of the foot It can have a better service life and is less prone to damage when moving and bending repeatedly. At the same time, an edge body 13 is provided on the edge of the upper body 11. Through multiple vertical yarns 133 and the lower TPU yarn layer 131 and the upper TPU yarn layer 132, and the floating horizontal yarn 135 and the sinking horizontal yarn 134 are woven into, the weaving density of the edge of the upper body 11 is high, thereby greatly improving the strength of the edge of the upper body 11, making it less likely to deform from the bottom and fail to hold the foot, and less likely to crack from the edge of the upper body 11.
