Description

Technical Field

[0001] This utility model relates to the field of semi-finished shoe upper technology, and in particular to a gradient woven shoe upper. Background Technology

[0002] Throughout the development of the footwear industry, the choice of upper materials has always been one of the core factors affecting the performance and user experience of footwear products. Among them, woven fabrics, with their unique weaving process creating a loose structure, have become an important branch of upper materials. The base layer of woven uppers is usually made by interlacing warp and weft yarns perpendicularly. The gaps between the yarns provide natural channels for air circulation, allowing heat and moisture generated by the feet to be quickly dissipated, thus significantly improving the breathability of footwear products. At the same time, woven fabrics themselves have a certain degree of softness, reducing friction when in contact with the foot and bringing a more comfortable wearing experience. Therefore, they are widely used in casual shoes, athletic shoes, and other fields.

[0003] However, the structural characteristics of woven upper base layers also introduce unavoidable performance defects. When subjected to external stretching or prolonged use, the gaps between the warp and weft yarns in the interwoven structure can easily expand, causing overall deformation of the upper. This deformation not only affects the shoe's appearance, causing it to become loose and lose its shape after a period of wear, but it can also reduce the upper's support for the foot due to insufficient structural stability, potentially increasing the risk of foot injury, especially during sports activities.

[0004] Therefore, the core issue addressed in this case is how to effectively solve the problem of easy deformation while preserving the breathability and comfort advantages of woven shoe uppers. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model proposes a gradient woven shoe upper to solve the problem of easy deformation of the base layer of woven shoe upper.

[0006] To solve the above-mentioned technical problems, the solution adopted by this utility model is as follows: a gradient woven upper, comprising a woven upper base layer, wherein a first reinforcing layer is provided on the woven upper base layer for limiting the front-to-back deformation of the upper, a second reinforcing layer is provided on the first reinforcing layer for limiting the left-to-right deformation of the upper, and a third reinforcing layer is provided on the second reinforcing layer for limiting the deformation of the tongue and heel; the first reinforcing layer comprises a plurality of first reinforcing groups distributed at intervals along the left-to-right direction; the first reinforcing group comprises a first reinforcing strip and a second reinforcing strip arranged along the front-to-back direction, the first reinforcing strip and the second reinforcing strip being mutually attached; the second reinforcing layer comprises a plurality of third reinforcing strips symmetrically arranged on the left and right sides of the woven upper base layer along the left-to-right direction.

[0007] A further improvement is that the first reinforcing strip includes a first embroidered cord and a first transparent nylon thread. The first embroidered cord is disposed on the woven shoe upper base layer along the front-to-back direction. The first transparent nylon thread wraps around the left and right sides of the first embroidered cord in a Z-shape and is sewn and fixed to the woven shoe upper base layer. The diameter of the first embroidered cord is 1.5-3mm.

[0008] A further improvement is that the second reinforcing strip is machine-sewn onto the woven shoe upper base layer by two parallel braided ropes along one side of the first embroidery rope, and the diameter of the braided ropes is 0.6-1.5mm.

[0009] A further improvement is that several of the third reinforcing strips radiate outward from the shoe tongue and are distributed in a fan shape on the woven upper base layer; the third reinforcing strip includes a second embroidered cord and a second transparent nylon thread, the second transparent nylon thread wraps around the left and right sides of the second embroidered cord in a Z-shape and is sewn and fixed to the woven upper base layer, and the diameter of the second embroidered cord is smaller than the diameter of the first embroidered cord.

[0010] A further improvement is that the third reinforcing layer includes a first TPU sheet and a second TPU sheet. The first TPU sheet is located at the shoe tongue and is hot-pressed and fixed to the woven upper base layer, while the second TPU sheet is located at the heel of the shoe and is hot-pressed and fixed to the woven upper base layer.

[0011] A further improvement is that the woven upper base layer is woven from two colors of yarn, and the woven upper base layer has different main colors at the front and rear ends, with a gradual transition to the other end.

[0012] A further improvement is that a third transparent nylon thread is machine-sewn onto the woven upper base layer from the rear end to the front end of the upper. The density of the third transparent nylon thread gradually decreases from the rear to the front, and the surface of the third transparent nylon thread is coated with a luminescent agent.

[0013] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0014] In this case, the woven upper base layer is made of two colors of yarn, with different main colors at the front and back ends, gradually transitioning towards the other end. This color design gives the shoe a unique visual appeal, enhancing its fashionability and attractiveness. A third transparent nylon thread, positioned to complement the gradient, provides reinforcement without disrupting the overall color harmony, maintaining a unified appearance. The stitching of the third transparent nylon thread to the woven upper base layer, with its gradually thinning density distribution from back to front, provides differentiated reinforcement support based on the stress characteristics of different parts of the upper. The denser stitching at the back effectively resists deformation caused by heel strikes, while the relatively sparser design at the front ensures basic stability while avoiding excessive stiffness. Combined with a glow-in-the-dark coating, this enhances structural strength and improves safety during nighttime use.

[0015] In the first reinforcing layer, the combination of the first and second reinforcing strips forms a "double line of defense" in the front and back directions. The first embroidered rope made of TPU material itself has strong tensile strength, and is then wrapped and sewn in a zig pattern by the first transparent nylon thread, which can firmly fix it to the rough woven surface of the shoe upper. The two parallel woven ropes serve as the second reinforcing strips, which are closely attached to the first embroidered rope, further enhancing the structural stability in the front and back directions. The combination of two different diameters and cross-sectional shapes of the threads not only improves the resistance to deformation, but also enhances the sense of layering of the shoe upper through the contrast of three-dimensionality.

[0016] The third reinforcing strip of the second reinforcing layer is distributed in a fan shape from the tongue outwards. It uses TPU thread with a smaller diameter than the first embroidered cord as the second embroidery cord and is also fixed with a zigzag stitching method. This design can specifically enhance the deformation resistance and wrapping support of the left and right sides of the upper, providing more reliable lateral restraint for the foot during exercise. The three-dimensional effect created by the contrast between the first embroidered cord and the braided cord, as well as the enhanced layering effect brought by the second embroidered cord sewn on the first embroidered cord and the braided cord, make the upper more stylish and refined.

[0017] The first and second TPU pieces of the third reinforcement layer are fixed to the shoe tongue and heel respectively through adhesive layer and hot pressing process. Utilizing the high elasticity and wear resistance of TPU material, the key problem of easy deformation of the shoe is precisely solved, so that the shoe tongue always maintains a firm shape, and the heel can maintain a stable wrap for the foot for a long time.

[0018] In this case, all reinforcing structures are integrated with the woven upper base layer using stitching or localized heat pressing. This avoids the blockage of gaps between yarns caused by large-area bonding, ensuring that air can still circulate freely through the natural channels of the woven fabric. Heat and moisture generated by the feet can be expelled promptly, maintaining dryness and comfort during wear. Simultaneously, all reinforcing strips are fixed by stitching, preventing the upper from stiffening due to glue hardening. The inherent softness of the woven fabric is preserved, reducing friction when in contact with the foot, making it particularly suitable for casual shoes and athletic shoes, which require prolonged wear.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0026] refer to Figures 1 to 6 This utility model discloses a gradient woven shoe upper 10, including a woven shoe upper base layer 10. The woven shoe upper base layer 10 is woven from two colors of yarn, and the main colors of the woven shoe upper base layer 10 are different at the front and rear ends, gradually transitioning to the other end. A third transparent nylon thread 11 is machine-sewn onto the woven shoe upper base layer 10 from the rear end of the shoe upper to the front end. The density of the third transparent nylon thread 11 gradually decreases from the rear to the front, and the surface of the third transparent nylon thread 11 is coated with a luminescent agent. After the third nylon thread is added to the woven shoe upper base layer 10 through the seam, it further increases the deformation resistance of the shoe upper, and the gradient position of the third transparent nylon thread 11 is adapted to the rear end color of the woven shoe upper base layer 10.

[0027] The woven upper base layer 10 is provided with a first reinforcing layer 12 for limiting the front-to-back deformation of the shoe upper, a second reinforcing layer 13 for limiting the left-to-right deformation of the shoe upper, and a third reinforcing layer 14 for limiting the deformation of the shoe tongue and heel. The first reinforcing layer 12 includes a plurality of first reinforcing groups 15 distributed at intervals along the left-to-right direction. The first reinforcing group 15 includes a first reinforcing strip 16 and a second reinforcing strip 17 arranged along the front-to-back direction, with the first reinforcing strip 16 and the second reinforcing strip 17 adhering to each other. The second reinforcing layer 13 includes a plurality of third reinforcing strips 18 symmetrically arranged along the left and right sides of the woven upper base layer 10.

[0028] The first reinforcing strip 16 includes a first embroidered cord 19 and a first transparent nylon thread 20. The first embroidered cord 19 is positioned on the woven upper base layer 10 along the front-to-back direction. The first transparent nylon thread 20 wraps around the embroidered cord 19 in a Z-shape on both sides and is sewn and fixed to the woven upper base layer 10. The diameter of the first embroidered cord 19 is 1.5-3mm, preferably 2.5mm. The second reinforcing strip 17 is machine-sewn to the woven upper base layer 10 by two parallel braided ropes 21 along one side of the first embroidered cord 19. The diameter of the braided ropes 21 is 0.6-1.5mm, preferably 1.2mm. The sewing of the first transparent nylon thread 20 fixes the first embroidered cord 19 to the woven upper base layer 10 in a non-adhesive manner, facilitating the firm fixation of the first embroidered cord 19 to the rough woven upper surface. The first transparent nylon thread 20 and the braided rope are fixed to the upper by sewing, increasing the strength of the upper and improving its resistance to deformation. The first embroidered cord 19 is a TPU thread with a circular cross-section, and the cross-section of the braided cord 21 is straight. The first embroidered cord 19 and the braided cord 21 are placed close together to increase the contrast of the three-dimensional effect and enhance the sense of layering of the insole.

[0029] Several third reinforcing strips 18 radiate outwards from the shoe tongue and are distributed in a fan shape on the woven upper base layer 10. Each third reinforcing strip 18 includes a second embroidered cord 22 and a second transparent nylon thread 23. The second transparent nylon thread 23 wraps around the left and right sides of the second embroidered cord 22 in a Z-shape and is sewn and fixed to the woven upper base layer 10. The diameter of the second embroidered cord 22 is smaller than the diameter of the first embroidered cord 19. The second embroidered cord 22 is a 1.5mm diameter TPU thread. The second embroidered cords 22 are laid out in a fan shape on the upper, greatly increasing the deformation resistance and support of the left and right sides of the upper. After being added to the upper, the second embroidered cord 22 is directly sewn onto the first embroidered cord 19 and the braided cord 21, further increasing the three-dimensionality of the upper. The second embroidered cord 22 also uses transparent nylon thread to cross-stitch on the upper, increasing the strength and deformation resistance of the upper.

[0030] The third reinforcing layer 14 includes a first TPU sheet 24 and a second TPU sheet 25. The first TPU sheet 24 is located at the shoe tongue and is tightly fixed to the woven upper base layer 10 by an adhesive layer and hot pressing. The second TPU sheet 25 is located at the heel of the shoe upper and is tightly fixed to the woven upper base layer 10 by an adhesive layer and hot pressing.
