Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of TPU shoe upper connection, in particular to a personalized breathable shoe upper. Background Art
[0002] TPU upper is a thermoplastic upper, which is formed into a porous and breathable upper by hot pressing TPU hot melt line. TPU upper has advantages such as breathability and wear resistance, but also has disadvantages of poor wrapping support strength. In addition, the current TPU upper has a single style. Contemporary young people like to be different, and traditional TPU uppers are difficult to meet the requirements of contemporary people for shoes.
[0003] In order to improve the wrapping support strength of the TPU upper and increase the personalization of the upper, this case was created. Utility Model Content
[0004] Therefore, in view of the above-mentioned problems, the utility model proposes a personalized breathable shoe upper with good wrapping support and strong personalization.
[0005] In order to solve the above technical problems, the solution adopted by the utility model is: a personalized breathable upper, comprising a TPU bottom layer, the TPU bottom layer is provided with a shoe opening, the TPU base layer is coated with a luminous coating, the luminous coating is covered with a TPU surface layer, and a TPU reinforcement layer is provided on the TPU surface layer;
[0006] The TPU surface layer includes a plurality of first hot-melt lines, which are arranged transversely on the TPU bottom layer, and the first hot-melt lines are spaced apart and sparsely along the longitudinal direction to form first light-transmitting gaps of different sizes to change the brightness of the luminous coating;
[0007] The TPU reinforcement layer includes a plurality of reinforcement strips, which are distributed on the left and right sides of the TPU surface layer. The reinforcement strips intersect with the first hot melt line, and the inner side of the reinforcement strips faces the center of the upper.
[0008] A further improvement is that the TPU surface layer also includes a plurality of second hot melt lines, which are longitudinally arranged on the TPU bottom layer, and the second hot melt lines are alternately spaced in the transverse direction to form second light-transmitting gaps of different sizes to change the brightness of the first light-transmitting gaps, and the reinforcement strips intersect with the second hot melt lines.
[0009] A further improvement is that the plurality of first heat-fusible threads are composed of heat-fusible threads of at least one color.
[0010] A further improvement is that a plurality of the second heat-fusible threads are composed of heat-fusible threads of at least one color.
[0011] A further improvement is that the width of the reinforcement strip gradually decreases from the outside to the inside along the length direction.
[0012] A further improvement is that a laser film layer is compositely arranged on the outer surface of the reinforcement strip.
[0013] By adopting the above technical solution, the beneficial effects of the utility model are:
[0014] In this case, the materials of the TPU base layer, TPU surface layer and TPU reinforcement layer are all made of TPU hot-melt wire winding. The processed upper is breathable and wear-resistant. The luminous coating coated on the TPU base layer is transparent during the day and does not affect the overall color matching of the upper.
[0015] The first hot melt lines on the TPU surface layer are arranged on the TPU bottom layer in a sparse and dense manner, blocking the local light of the luminous coating, so that the luminous coating emits strong and weak light at night, increasing the personalization of the TPU upper. At the same time, the first hot melt lines on the TPU surface layer are arranged horizontally, increasing the horizontal wrapping support of the TPU upper. By adjusting the color matching of the first hot melt lines, different upper styles can be presented.
[0016] The reinforcement strips on the TPU reinforcement layer are arranged to intersect with the first hot-melt line, thereby improving the composite strength of the TPU surface layer and the TPU bottom layer and improving the overall wrapping support of the upper.
[0017] A further beneficial effect is that the second hot-melt line on the TPU surface layer increases the longitudinal wrapping support of the TPU upper, while partially blocking the light transmitted through the first light-transmitting gap, so that the light transmitted through the entire upper is bright in the middle and weak around the light-transmitting gap.
[0018] A further beneficial effect is that the first hot-melt line and the second hot-melt line can be the same color or different colors, and the TPU shoe upper can present different color styles by matching the colors of the first hot-melt line and the second hot-melt line.
[0019] A further beneficial effect is that the width of the reinforcing strip gradually decreases from the outside to the inside along the length direction, so that the wrapping support force of the upper decreases from the outside to the inside, reducing the restriction on the deformation of the middle part of the upper, i.e. the instep, and improving the comfort of the instep.
[0020] A further beneficial effect is that the laser film layer disposed on the outer surface of the reinforcing strip improves the overall design sense of the shoe upper. BRIEF DESCRIPTION OF THE DRAWINGS
