Description

Technical Field

[0001] This utility model relates to shoe upper materials, and in particular to a warp-knitted fabric with a three-dimensional anti-tension structure. Background Technology

[0002] In the field of shoe upper materials, the breathability of the upper is crucial to the quality and wearing experience of the shoe. To provide breathability, ventilation holes are usually designed into the upper. These ventilation holes are distributed in one or more planar layers. However, the ventilation effect of these planar ventilation holes is limited, and they lack cushioning and softness, failing to effectively reduce pressure points. Prolonged wear can cause fatigue and discomfort in the feet.

[0003] To address the aforementioned issues, the "sandwich" structure of the shoe upper material, by filling the space between the top and bottom layers, can achieve a certain level of cushioning and softness, but it obviously hinders airflow and reduces breathability.

[0004] Therefore, it is of practical significance to improve the air circulation performance of shoe upper materials while providing cushioning and pressure relief effects to enhance wearing comfort. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a warp-knitted fabric with a three-dimensional anti-pull structure. This fabric has a three-layer structure consisting of a face layer, a middle layer, and a bottom layer. The middle layer is a three-dimensional jacquard column formed by the cross-pulling of the face layer yarn and the bottom layer yarn. Combined with the characteristics of thermoplastic elastic yarn, the fabric itself has a three-dimensional effect. After heat setting treatment, the three-dimensional structure can be further enhanced and fixed, making the overall structure more stable, while also providing air circulation and cushioning pressure relief.

[0006] To solve this technical problem, the present invention adopts the following solution:

[0007] A warp-knitted fabric with a three-dimensional anti-tightening structure includes a face layer, a middle layer, and a bottom layer. The face layer includes multiple face layer yarns that are woven in loops to form the face layer. The bottom layer includes multiple bottom layer yarns that are woven in loops to form the bottom layer. The middle layer consists of multiple connecting portions formed by interlacing and pulling a portion of the face layer yarns and a portion of the bottom layer yarns. The connecting portions are located between the face layer and the bottom layer.

[0008] In this invention, the cross-pulling is formed by thermoplastic yarns being pulled back and forth between the surface layer and the bottom layer. This method is different from the conventional yarn pulling of flat layers (such as the surface or bottom layer of a fabric). This invention uses yarns distributed in different layers to pull back and forth, which can create a cavity structure in the middle and guide the surface layer and the bottom layer to form an arch structure. Conventional yarn pulling of flat layers (such as the surface or bottom layer of a fabric) does not have this effect.

[0009] Furthermore, the surface layer and the bottom layer include a plurality of continuously arranged arched structures, with the openings of the arched structures of the surface layer opposite to the openings of the arched structures of the bottom layer.

[0010] Furthermore, the arched structures of the surface layer and the bottom layer have the same span and the same height, and the openings of the arched structures of the surface layer and the bottom layer both face the middle layer and are staggered by a certain distance.

[0011] Furthermore, the arched structures of the surface layer and the bottom layer have different spans and / or inconsistent heights, and the arched structure of the surface layer is parallel and symmetrical to the arched structure of the bottom layer.

[0012] Furthermore, the spans and / or heights of the arched structures in the surface layers are different, and the openings of the arched structures in the surface layers and the openings of the arched structures in the bottom layers both face the middle layer and are staggered by a certain distance; or,

[0013] The arched structures of the bottom layer have different spans and / or inconsistent heights. The openings of the arched structures of the top layer and the bottom layer are both directed toward the middle layer and staggered by a certain distance.

[0014] Furthermore, the connecting portions of the intermediate layer are continuously connected, so that the intermediate layer forms a plurality of continuous cavities.

[0015] Furthermore, the connecting portions of the intermediate layer are intermittently connected, resulting in partial hollowing out of the intermediate layer.

[0016] Furthermore, the surface layer and / or the bottom layer are 3D mesh fabrics.

[0017] Furthermore, the surface layer and / or the bottom layer are partially provided with ventilation holes.

[0018] Furthermore, the connecting portions of the intermediate layer are continuously connected, forming multiple continuous cavities in the intermediate layer, or the connecting portions of the intermediate layer are intermittently connected, resulting in partial hollowing out of the intermediate layer.

[0019] By adopting the aforementioned technical solution, compared with the prior art, this utility model gives the fabric a three-dimensional structure by forming an intermediate layer through the pull of the top and bottom layers. The cavity structure of this intermediate layer increases the cushioning effect, provides additional softness, effectively reduces pressure points, provides better support for the feet, and is less likely to cause fatigue and pain when worn for a long time, thus improving the wearing experience.

[0020] On the other hand, the fabric has excellent breathability. By utilizing the arched structure of the surface layer and the jacquard design of the middle layer, the contact area with fluids and other media is increased, improving heat exchange efficiency and reducing stuffiness in the feet when wearing it.

[0021] Furthermore, this fabric structure integrates an arched structure and 3D contours on the surface. The top, middle, and bottom layers work together to create a louver effect. For example, by modifying the middle layer's process, the porosity of the locally perforated areas is increased, increasing the air contact area. The arched structure guides airflow, effectively directing air movement. The top and bottom layers, with their individual Jacquard openings and Jacquard pull-out openings, further enhance the breathability of the mesh, allowing heat generated by the feet to escape more smoothly and fresh air to enter more easily, solving the problem of poor air circulation in traditional shoe upper mesh fabrics.

[0030] Example 1:

[0031] refer to Figure 1 The warp-knitted fabric with a three-dimensional anti-pull structure includes a face layer 1, a middle layer 2, and a bottom layer 3. The face layer 1 includes multiple face yarns that are woven in loops to form the face layer 1. The bottom layer 3 includes multiple bottom yarns that are woven in loops to form the bottom layer 3. The middle layer 2 is formed by cross-pulling of some face yarns and some bottom yarns to form multiple connecting parts. The connecting parts are located between the face layer and the bottom layer and have a cavity structure 5.

[0032] Specifically, both the top layer 1 and the bottom layer 3 include multiple continuously arranged arched structures with the same span and height. The openings of the arched structures in both the top layer 1 and the bottom layer 3 face the intermediate layer but are offset by a certain distance. In other words, the individual arched structures of the top and bottom layers are not directly opposite each other. That is, if the top layer is rotated 180°, it needs to be translated by a certain displacement to offset its original position before it can coincide with the bottom layer. This offset design is to create a cross-tensioning effect in the intermediate layer that connects the top and bottom layers.

[0033] In this embodiment, the outer layer is woven from nylon monofilament yarn and is located on the upper part of the mesh fabric, providing excellent breathability and permeability. The middle layer contains jacquard columns made of TPEE monofilament yarn, forming a double-arched wave effect through the tension between the outer and bottom layers (one arched wave on the outer layer and another on the bottom layer), enhancing the overall three-dimensionality and visual effect. The double-arched wave effect has a continuous cavity effect inside, i.e., the middle layer, which increases the cushioning effect, provides additional softness and comfort, effectively reduces pressure points, and improves the wearing experience. The bottom layer is woven from nylon monofilament yarn and is located on the lower part of the mesh fabric, providing excellent breathability and permeability. The outer layer is specially designed with an arched structure effect pattern, as referenced... Figure 1 The continuous arched structure not only enhances the visual appeal but also provides additional support and comfort.

[0034] This embodiment is merely exemplary, and the present invention is not limited to this structure. Those skilled in the art should realize that the intermediate layers can also be intermittently connected, allowing for partial perforation of the intermediate layers, thereby improving breathability. The yarns used for the surface and bottom layers can also be other thermoplastic yarns, and do not necessarily have to be nylon.

[0035] Example 2:

[0036] refer to Figure 2 The warp-knitted fabric with a three-dimensional anti-pull structure includes a face layer 1, a middle layer 2, and a bottom layer 3. The face layer 1 includes multiple face yarns that are woven in loops to form the face layer 1. The bottom layer 3 includes multiple bottom yarns that are woven in loops to form the bottom layer 3. The middle layer 2 is formed by cross-pulling of some face yarns and some bottom yarns to form multiple connecting parts. The connecting parts are located between the face layer and the bottom layer and have a cavity structure 5.

[0037] Specifically, both the top layer 1 and the bottom layer 3 include multiple continuously arranged arched structures. The adjacent arched structures in the top layer have different spans and inconsistent heights, while the adjacent arched structures in the bottom layer have the same span and consistent height. The openings of the arched structures in both the top and bottom layers face the intermediate layer and are staggered by a certain distance, thus forming a continuous, cross-connected intermediate layer between the top and bottom layers.

[0038] In this embodiment, both the top and bottom layers are woven from nylon monofilament yarns, providing excellent breathability and permeability. The middle layer contains jacquard columns made of TPEE monofilament yarns. Due to the varying spans of the arched wave structure, the top and bottom layers are pulled together to create a continuous hollow cylindrical effect of varying sizes, enhancing the overall three-dimensionality and visual appeal. Furthermore, the hollow cylinders increase cushioning, providing additional softness and comfort, effectively reducing pressure points and improving the wearing experience. Additionally, the different undulations of the arched waves on the top and bottom layers give the fabric two distinct textures, creating a differentiated feel.

[0039] This embodiment is merely exemplary, and the present invention is not limited to this structure. Those skilled in the art should realize that the intermediate layers can also be intermittently connected, allowing for partial perforation of the intermediate layers, thereby improving breathability. The yarns used for the surface and bottom layers can also be other thermoplastic yarns, and do not necessarily have to be nylon.

[0040] Example 3:

[0041] refer to Figure 3 The warp-knitted fabric with a three-dimensional anti-pull structure includes a face layer 1, a middle layer 2, and a bottom layer 3. The face layer 1 includes multiple face yarns that are woven in loops to form the face layer 1. The bottom layer 3 includes multiple bottom yarns that are woven in loops to form the bottom layer 3. The middle layer 2 is formed by cross-pulling of some face yarns and some bottom yarns to form multiple connecting parts. The connecting parts are located between the face layer and the bottom layer and have a cavity structure 5.

[0042] Specifically, both the top layer 1 and the bottom layer 3 consist of multiple continuously arranged arched structures. Adjacent arched structures in the top layer have different spans and heights; similarly, adjacent arched structures in the bottom layer have different spans and heights. The openings of the arched structures in both the top and bottom layers face the intermediate layer and are offset by a certain distance. If the top layer is rotated 180°, it needs to be translated to offset its original position before aligning with the bottom layer. This also creates a continuous, intersecting intermediate layer between the top and bottom layers.

[0043] In this embodiment, both the top and bottom layers are woven from nylon monofilament yarns, providing excellent breathability and permeability. The middle layer contains jacquard columns made of TPEE monofilament yarns. Due to the uneven spacing of the arched wave structure, the top and bottom layers are pulled together to create a continuous hollow cylindrical effect of varying sizes, enhancing the overall three-dimensionality and visual appeal.

[0044] This embodiment is merely exemplary, and the present invention is not limited to this structure. Those skilled in the art should realize that the intermediate layers can also be intermittently connected, allowing for partial perforations in the intermediate layers, thereby improving breathability. Furthermore, the yarns used for the surface and bottom layers can also be other thermoplastic yarns, and do not necessarily have to be nylon.

[0045] Example 4:

[0046] refer to Figure 4 The warp-knitted fabric with a three-dimensional anti-pull structure includes a face layer 1, a middle layer 2, and a bottom layer 3. The face layer 1 includes multiple face yarns that are woven in loops to form the face layer 1. The bottom layer 3 includes multiple bottom yarns that are woven in loops to form the bottom layer 3. The middle layer 2 is formed by cross-pulling of some face yarns and some bottom yarns to form multiple connecting parts. The connecting parts are located between the face layer and the bottom layer and have a cavity structure 5.

[0047] Specifically, both the top layer 1 and the bottom layer 3 include multiple continuously arranged arched structures. The arched structures in the top layer 1 and the bottom layer 3 have the same span but different heights. The arched structures in the top layer 1 and the bottom layer 3 are parallel and symmetrical, with the axis of symmetry being the midline between the top layer 1 and the bottom layer 3. The two ends of the arched structures in the top layer with opposite openings, and the two ends of the arched structures in the bottom layer, are connected in an X-shape to form multiple continuously connected sections. Both the top and bottom layers are woven from nylon monofilament yarns, providing good breathability and permeability. The middle layer contains continuously connected jacquard columns made of TPEE monofilament yarns, forming multiple parallel continuous cavities between the top and bottom layers.

[0048] This embodiment is merely exemplary, and the present invention is not limited to this structure. Those skilled in the art should realize that the intermediate layers can also be intermittently connected, making the intermediate layers partially hollow, thereby improving the breathability.

[0049] Example 5:

[0050] refer to Figure 5 The warp-knitted fabric with a three-dimensional anti-pull structure includes a face layer 1, a middle layer 2, and a bottom layer 3. The face layer 1 includes multiple face yarns that are woven in loops to form the face layer 1. The bottom layer 3 includes multiple bottom yarns that are woven in loops to form the bottom layer 3. The middle layer 2 is formed by cross-pulling of some face yarns and some bottom yarns to form multiple connecting parts. The connecting parts are located between the face layer and the bottom layer and have a cavity structure 5.

[0051] Specifically, both the top layer 1 and the bottom layer 3 include multiple continuously arranged arched structures, and both are 3D three-dimensional mesh fabrics with evenly distributed holes 4. Both the top and bottom layers are woven from nylon monofilament yarns, providing excellent breathability and permeability. The middle layer contains jacquard columns composed of TPEE monofilament yarns. After high-temperature dyeing and setting, the 3D three-dimensional mesh fabric exhibits excellent resilience. High-temperature setting rearranges the molecular chains, fixing the wavy jacquard structure and ensuring the long-term stability of the breathable pores.

[0052] In this embodiment, the intermediate layer is made of thermoplastic elastic material. If a non-elastic material is used, the unique arched bridge structural effect and local louver effect will not be achieved after high-temperature dyeing and setting. The connecting parts of the intermediate layer can be continuously connected, forming multiple continuous cavities; or they can be intermittently connected, creating localized openwork in the intermediate layer. By adjusting the stitch ratio during the weaving of the intermediate layer, such as the difference in the ratio between dense and open areas, the breathability and strength requirements of the fabric can be further balanced.

[0053] In other embodiments, ventilation holes can be provided in specific areas of the surface layer and / or bottom layer. These holes, such as circular or elliptical ventilation holes, are created at appropriate locations on the 3D mesh using Jacquard technology, achieved through single Jacquard openings or Jacquard pull-out openings. These ventilation holes are smaller than the 3D open spaces (4), further enhancing the breathability and airflow of the mesh. When wearing shoes with uppers made from this mesh, heat generated by the feet can escape more easily through these openings, while fresh air from the outside can enter more readily, effectively improving wearing comfort and preventing discomfort caused by stuffiness.

[0054] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
