Technical Field
[0001] The utility model relates to the technical field of TPU shoe uppers, in particular to a TPU breathable shoe upper with a rope embroidery structure. Background Art
[0002] TPU upper is a thermoplastic upper. It is formed into a breathable upper with holes by hot pressing TPU hot melt line. It is breathable, wear-resistant and lightweight, and is deeply loved by consumers. The amount of glue used in the manufacturing process of TPU upper is reduced, and the trimming waste can be reused. It is green and environmentally friendly, and is the current trendy upper.
[0003] TPU uppers have many advantages, but they also have disadvantages. The holes on the TPU uppers are breathable and comfortable, and the TPU hot melt lines are wear-resistant, but the uppers as a whole are also easy to deform, which makes the TPU uppers have poor support for the feet and cannot support the feet well. In addition, the existing TPU uppers have a single style and cannot meet consumers' pursuit of trendy uppers.
[0004] This case arises to solve the above problems. Utility Model Content
[0005] Therefore, in order to solve the above problems, the utility model proposes a TPU breathable shoe upper with a rope embroidery structure which is a combination of a TPU hot-melt thread and an embroidery rope.
[0006] In order to solve the above technical problems, the solution adopted by the utility model is: a TPU breathable upper with a rope embroidery structure, comprising a base layer, a shoe opening is opened on the base layer, a first reinforcement layer is compositely arranged on the base layer, a second reinforcement layer for limiting the deformation of the front and rear of the shoe to strengthen the wrapping support force of the toe and the heel is arranged on the first reinforcement layer, and a rope embroidery layer is arranged on the second reinforcement layer;
[0007] The first reinforcement layer comprises a plurality of first heat-fusible line groups arranged along the periphery of the base layer toward the center of the base layer, the first heat-fusible line groups are arranged at intervals, and the laying width between the first heat-fusible lines on the first heat-fusible line groups gradually decreases from the outside to the inside;
[0008] The second reinforcement layer comprises a front second hot-melt line group laid on the toe and a rear second hot-melt line group laid on the heel, and the second hot-melt lines of the front second hot-melt line group and the rear second hot-melt line group are laid on the first reinforcement layer in an arc shape from the left side to the right side of the base layer;
[0009] The rope embroidery layer includes a plurality of embroidery ropes, each having a strand diameter of 2-5 mm. The embroidery rope is located between two adjacent groups of first hot-melt thread groups and fits the shape of one group of first hot-melt thread groups and is laid from the periphery of the base layer to the center of the base layer. The embroidery rope is glued or sewn onto the base layer and the second reinforcement layer.
[0010] A further improvement is that a first movable distance is formed between the inner ends of a plurality of groups of the first thermal fuse groups.
[0011] A further improvement is that a third reinforcement layer is arranged between the first reinforcement layer and the second reinforcement layer to increase the support force of the upper wrapping, and the third reinforcement layer includes four groups of third hot melt line groups arranged on the front and back and left and right sides of the base layer, and the third hot melt lines on the third hot melt line groups are laid in an L shape along the front and back and left and right directions on the base layer and the second reinforcement layer, and a second active spacing is formed between the L-shaped tips of the four groups of third hot melt line groups.
[0012] A further improvement is that the first movable spacing and the second movable spacing are staggered front and back in the middle of the base layer.
[0013] A further improvement is that the inner ends of two adjacent embroidery ropes are integrally connected to form a U-shaped head.
[0014] A further improvement is that the strand diameter of the embroidery rope is 3 mm.
[0015] By adopting the above technical solution, the beneficial effects of the utility model are:
[0016] The base layer in this case can be deformed along the front, back, left, and right directions. The first hot-melt thread group arranged in a curve on the first reinforcement layer limits the deformation of the base layer in the front, back, left, and right directions, thereby improving the overall wrapping support of the upper. The laying width of the first hot-melt thread group gradually decreases from the periphery of the base layer to the inside, and the deformation restriction area on the outer periphery of the base layer is greater than the deformation restriction area on the middle part of the base layer. While improving the wrapping support of the outer side of the base layer to the foot, the restriction of the middle part to the instep movement is reduced, thereby improving the wearing comfort of the upper. The front second hot-melt thread group and the rear second hot-melt thread group set on the second reinforcement layer are laid on the toe and heel of the upper respectively, further limiting the deformation of the toe and heel, and improving the wrapping support of the upper to the toe and heel. The front second hot-melt thread group strengthens the stability of the front and back parking, and the rear second hot-melt thread group improves the anti-lateral sprain capability of the upper. The embroidery rope on the rope embroidery layer is adapted to the first hot-melt thread group on the first reinforcement layer, which can improve the overall wrapping support of the upper while also improving the overall design sense of the upper to meet consumers' pursuit of trendy uppers.
[0017] A further beneficial effect is that the first movable spacing formed between the inner ends of the first hot-melt wire group reduces the movement restriction of the instep, allowing the instep to move up and down along the direction perpendicular to the surface layer, thereby improving the wearing comfort of the shoe upper.
[0018] Further beneficial effects are: the third hot melt line on the third reinforcement layer intersects with the first hot melt line on the first reinforcement layer, further enhancing the wrapping support performance of the upper; the second movable spacing formed between the L-shaped tips of the four groups of third hot melt line groups reduces the restriction on the movement of the instep, allowing the instep to move up and down along the vertical surface layer, thereby improving the wearing comfort of the upper.
[0019] A further beneficial effect is that the inner ends of two adjacent embroidery ropes are integrally connected to form a U-shaped head, which facilitates the embroidery ropes to be continuously wound and laid on the surface layer. BRIEF DESCRIPTION OF THE DRAWINGS
