Description

Technical Field

[0001] This invention relates to the field of textile and footwear upper manufacturing, and in particular to a warp-knitted fabric with a three-dimensional anti-tension structure and its manufacturing process. Background Technology

[0002] In the field of textile technology, the performance of shoe upper materials is crucial to the quality and wearing experience of shoes. Traditional shoe upper materials have certain limitations in terms of breathability, comfort, and aesthetics, making it difficult to meet consumers' demands for high-quality, functional shoe uppers. Specifically, these limitations include the following:

[0003] Breathability and heat exchange issues: Traditional mesh uppers have poor air circulation and low heat exchange efficiency. When worn, heat generated by the feet is difficult to escape, and fresh air from the outside cannot easily enter, leading to stuffy feet, affecting wearing comfort, and being detrimental to foot health.

[0004] Comfort issues: The lack of effective cushioning and soft design means that pressure points cannot be effectively reduced during walking or exercise. Prolonged wear can easily cause foot fatigue and pain, failing to provide good support and comfort for the feet.

[0005] Aesthetic issues: The patterns and designs on the shoe uppers are rather monotonous and lack variety, making it difficult to meet the increasingly diverse aesthetic needs of consumers and failing to keep up with current fashion trends, thus lacking an appearance advantage in market competition.

[0006] To improve breathability, comfort, and aesthetics, warp knitting equipment can be used to weave warp-knitted products, with jacquard layers and perforated meshes designed in certain areas. Furthermore, a three-dimensional structure can be formed by layering multiple layers. Summary of the Invention

[0007] The purpose of this invention is to overcome the problems existing in the prior art and provide a warp-knitted fabric with a three-dimensional anti-pull structure and its manufacturing process. This fabric forms an intermediate layer between the surface layer and the bottom layer by anti-pulling the surface layer and the bottom layer, which can solve the problems of traditional shoe upper mesh fabric in terms of breathability, comfort, aesthetics and production process flexibility.

[0008] The warp-knitted fabric with a three-dimensional anti-pull structure provided by the present invention includes a surface layer and a bottom layer. Parts of the yarns constituting the surface layer and part of the yarns constituting the bottom layer are cross-pulled to form multiple intermediate layers connected between the surface and the bottom.

[0009] The face layer is mainly woven by nylon monofilament yarn, and polyester, nylon and other yarns can also be woven in other embodiments. In different cases, the yarn threading method is various, such as 9-thread 1-empty in Example 1, cooperating with specific gear feed and warp knitting basic organization; 1-thread 1-empty in Examples 4, 5, 6 and 7, cooperating with jacquard comb basic organization, and changing the pattern effect of needle method. The design of arch bridge effect, parallel symmetric half-cavity cylinder and other patterns not only enhances the visual beauty of the shoe face, but also provides additional support, so that the shoe face can better fit the foot when worn and distribute pressure. At the same time, the nylon monofilament yarn itself has good air permeability and permeability, which helps air circulation.

[0010] The intermediate layer is composed of thermoplastic yarn (TPEE monofilament yarn), preferably high-elasticity high-shrinkage yarn, which can be TPEE monofilament yarn or coated elastic yarn in specific embodiments. Elastic yarn such as spandex and spandex processed yarn is used for non-transparent fabric as needed. In Example 1, GB3 and GB4 yarns are threaded in 1-thread 9-empty mode, and specific warp knitting basic organizations are cooperated with each other to form double-S arch bridge wave effect by face-to-bottom pulling; in Example 2, a hollow cylindrical effect is formed; in Examples 3-7, different threading methods, warp knitting organizations and process changes are used to realize hollow 3D jacquard effect, single-jacquard opening and jacquard opening, etc. These unique effects increase the contact area with fluid and other media, and improve the heat exchange efficiency. The internal cavity structure increases the buffering effect, provides additional softness, reduces the pressure points, and improves the wearing comfort. Moreover, in Example 3, the air permeability and strength requirements can be balanced by adjusting the needle span ratio, such as the process changes of intermediate layers GB4 and GB5.

[0011] The bottom layer can be woven with the same nylon monofilament yarn as the face layer, and the threading method and warp knitting basic organization are similar to those of the face jacquard layer. In specific embodiments, the bottom layer can also use different yarns from the face layer, as long as it can cooperate with the face layer to form a pulling intermediate layer. When forming double-S arch bridge wave, cavity cylinder and other effects, it is pulled with the face jacquard layer, making the overall structure more stable. Moreover, the bottom jacquard base layer also has good air permeability and permeability, which helps the air circulation of the overall shoe face.

[0012] The warp knitting jacquard process provided by the application is difficult to form an intermediate layer through the face layer and the bottom layer. In order to connect the face layer and the bottom layer, the conventional process generally adopts the mode that the yarns are connected to the face layer and the bottom layer in sequence, and such a mode has the risk of delamination. The inventors adopt the mode of pulling the face layer and the bottom layer in pairs, and the two layers are directly connected, so that a unique intermediate warp knitting column can be formed; such a direct connection can prevent delamination and also form a unique hollow cavity effect. The conventional laminated process is to form another layer on the basis of one layer or to fill a buffer material in the middle of two layers, and such a mode can cause the problems of insufficient air permeability and poor comfort. In the application, the face layer, the intermediate layer and the bottom layer are simultaneously knitted, and such a mode is different from the sandwich net cloth. The sandwich net cloth is a double needle bed warp knitting net cloth with a three-dimensional structure, which is composed of three layers of mesh surfaces, connecting filaments and flat cloth bottom surfaces, and has a sandwich hamburger sandwich structure. The intermediate guide bar of the sandwich net cloth is formed by alternating the spacer yarn to form a sandwich jacquard structure, and also has the problem of delamination.

[0013] In the warp knitting jacquard process provided by the application, the yarn feeding and the warp let-off amount are controlled, for example, different layers of yarns adopt specific yarn feeding modes, such as 9-1, 1-9 and 2-1, and are matched with accurate gear warp let-off amounts, such as the different warp let-off amount settings of GB1-GB6 in Example 1. Such accurate control determines the distribution and density of the yarns in the knitting process, thereby affecting the structure and performance of the net cloth. Suitable yarn feeding modes and warp let-off amounts can ensure the close combination between the layers and also form specific patterns and structures, such as arch bridge, cylinder and other 3D textures.

[0014] The warp knitting jacquard process provided by the application can be flexibly used for warp knitting basic structures, for example, different guide bars (GB1-GB8) adopt different warp knitting basic structures, and the selection and combination of these basic structures determine the yarn interlacing mode and the texture structure of the net cloth. Different warp knitting basic structures are matched with each other to form specific effects of face-bottom pulling, such as double S arch bridge wave and hollow cylinder effects, thereby enhancing the three-dimensionality and functionality of the net cloth.

[0015] The warp knitting jacquard process provided by the application demonstrates process optimization and innovation through specific examples, for example, in Example 3, based on Example 1, the process of the intermediate jacquard layers GB4 and GB5 is changed to realize a local hollow effect, increase the air contact area and strengthen heat exchange, and the face-bottom connection is realized through different cross-needle parts to improve the physical properties and tear resistance of the net cloth. After the knitting method in Examples 1-3, Examples 4-7 introduce the Jakard technology, and the Jakard drawing board and needle method can be flexibly adjusted to change the width of the face layer column and the width of the arch bridge effect, and also appropriately open the holes to improve the air permeability. Furthermore, the Jakard pulling process in Examples 6 and 7 enriches the pattern design, optimizes the air permeability and mechanical properties, meets the personalized needs, and improves the overall stability and anti-deformation ability of the net cloth.

[0016] Specifically as follows:

[0017] A warp-knitted fabric with a three-dimensional counter-pulling structure, comprising a face layer, an intermediate layer and a bottom layer, wherein the face layer comprises a plurality of face layer yarns, the face layer yarns are loop-knitted to form the face layer; the bottom layer comprises a plurality of bottom layer yarns, the bottom layer yarns are loop-knitted to form the bottom layer; the intermediate layer is formed by the cross-pulling of thermoplastic yarns between the face layer and the bottom layer to form a plurality of connecting parts, the connecting parts are located between the face layer and the bottom layer, and the shrinkage rate of the intermediate layer yarns is higher than that of the face layer yarns and the bottom layer yarns.

[0018] The present application also protects the manufacturing process of the warp-knitted fabric with the three-dimensional counter-pulling structure, comprising the following steps: S1, setting the guide bar: preparing the guide bar of the warp-knitting equipment and setting the guide bar; S2, warping: the intermediate layer adopts elastic thermoplastic yarns; S3, threading: the face layer and the bottom layer are threaded in the same way, and the intermediate layer is threaded in a different way from the face layer and the bottom layer; S4, knitting: the face layer and the bottom layer are knitted in the same way, and the intermediate layer is knitted in a different way from the face layer and the bottom layer.

[0019] Beneficial effects: The present application effectively solves the various technical problems existing in traditional vamp mesh through the innovative multi-layer breathable vamp mesh warp-knitted jacquard manufacturing method, and realizes significant technical effect improvement in functionality, aesthetics and production process. Compared with the prior art, it has the following advantages:

[0020] 1. Improve the air permeability and heat exchange efficiency, including:

[0021] Air circulation optimization: the face layer, the intermediate layer and the bottom layer cooperate with each other to form a louver effect, such as in the hollow 3D three-dimensional jacquard effect, through the process change of the intermediate layer, the porosity of the local hollow area is improved, the air contact area is increased, the air flow is guided by the arched structure, and the air flow is effectively guided. The single-jacquard opening and the jacquard counter-pulling opening process further improve the air permeability of the mesh, so that the hot air generated by the feet can be more smoothly discharged, and fresh air from the outside can also be more easily entered, solving the problem of poor air circulation of traditional vamp mesh.

[0022] Heat exchange enhancement: the intermediate layer is designed with a wavy effect jacquard, such as double S arch bridge wave, hollow cylinder, etc., which increases the contact area with fluid and other media, improves the heat exchange efficiency, and improves the stuffiness of the feet when wearing.

[0023] 2. Improve comfort, including:

[0024] Buffer and decompression: double S arch bridge wave (i.e. equidistant arch bridge wave effect), cavity cylinder and hollow 3D hollow jacquard layer inside the cavity structure, increase the buffering effect, provide additional softness, can effectively reduce the pressure point, provide better support for the foot, long time wearing is not easy to produce fatigue and pain, improve the wearing experience.

[0025] Material matching: the light reflectivity of TPEE light monofilament and nylon light yarn is consistent, which ensures the uniformity of the visual quality of the vamp, and the material characteristics help to improve the overall comfort, avoiding the influence of material difference on the wearing feeling.

[0026] 3. Enhance the appearance

[0027] The present application can realize various pattern designs, through different threading methods, warp knitting basic organizations and the application of jacquard technology and jacquard counter draw process, various unique pattern effects such as double S arch bridge wave, cavity cylinder and hollow 3D jacquard are realized, and the pattern is rich and varied, which can meet the individual needs of different customers for the appearance of the vamp, and can meet the needs of fashion trends and product uniqueness.

[0028] 4. Optimize production process flexibility

[0029] The present application can realize quick response to demand, after introducing the jacquard technology, within a reasonable process range, the width of the column and the arch bridge effect can be quickly and conveniently adjusted according to the specific needs of customers. Compared with the traditional warp knitting process, which needs to re-deduce the complex process when facing customer demand adjustment, consumes a lot of manpower and material resources, the jacquard technology greatly improves the production efficiency, reduces the production cost, shortens the production cycle, and makes the production more quickly respond to market changes.

[0037] The preferred embodiments of the present application will be described in more detail below. Although the preferred embodiments of the present application are described below, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. If no specific technology or condition is specified in the examples, the technology or condition described in the literature in the art or according to the product manual is used. If no manufacturer of the reagent or instrument is specified, it is a conventional product that can be obtained by purchase. In the following examples, unless otherwise specified, "%" refers to the percentage by weight.

[0038] Example 1 (equal-interval arch bridge wave effect)

[0039] Reference Figure 1 The tridimensional interlacing structure warp-knitted fabric includes a surface layer 1, an intermediate layer 2, and a bottom layer 3. The surface layer 1 includes a plurality of surface layer yarns, and the surface layer yarns are looped and knitted to form the surface layer 1. The bottom layer 3 includes a plurality of bottom layer yarns, and the bottom layer yarns are looped and knitted to form the bottom layer 3. The intermediate layer 2 is formed by interlacing and pulling part of the surface layer yarns and part of the bottom layer yarns to form a plurality of connecting portions, and the connecting portions are located between the surface layer and the bottom layer and have a cavity structure 5.

[0040] Specifically, the surface layer 1 and the bottom layer 3 each include a plurality of continuously arranged arch structures, and the arch structures have the same span and the same height. The arch structure openings of the surface layer 1 and the arch structure openings of the bottom layer 3 are both directed toward the intermediate layer and are staggered by a distance. That is, the single arch structure of the surface layer and the bottom layer is not in a directly opposite position. If the surface layer is rotated by 180°, it still needs to be translated by a displacement so as to be staggered with the position of the surface layer before rotation, so as to coincide with the bottom layer. Such staggered design is to form the intermediate layer for connecting the surface layer and the bottom layer to produce the interlacing and pulling effect.

[0041] The manufacturing process of the tridimensional interlacing structure warp-knitted fabric is described below with reference to Figure 2 , which includes the following steps:

[0042] S1: Setting of the guide bar: The guide bar of the warp-knitting equipment is set, and at least six guide bars are included, and the ground bar guide bar GB1, the ground bar guide bar GB2, the ground bar guide bar GB3, the ground bar guide bar GB4, the ground bar guide bar GB5, and the ground bar guide bar GB6 are sequentially arranged from the front needle bed to the back needle bed.

[0062] S4 weave: The surface layer includes:

[0063] GB1: Basic warp knitting structure 1-0 / 1-2 / / ;

[0065] Intermediate layer:

[0068] Bottom layer:

[0069] GB5: Basic warp knitting structure 1-0 / 1-2 / / ;

[0070] GB6: Basic warp knitting structure 1-2 / 1-0 / / ;

[0071] S5 heat treatment:

[0072] The woven fabric is then subjected to high-temperature setting at 90℃ for 1 hour. After high-temperature setting, the molecular chains rearrange, which can fix the wavy jacquard structure and ensure the long-term stability of the breathable pores. This heat treatment process can also be combined with the fabric dyeing process, that is, by using high-temperature color-fixing baking after the fabric is dyed, the setting effect can be achieved.

[0073] For the yarn padding motion diagram in the above manufacturing process, please refer to [link / reference]. Figure 3 .from Figure 3 The effect of the yarn at the bottom of the surface layer can be seen. Figure 3The upper side is a face layer, and the lower side is a bottom layer. The plane effects of the two are completely staggered. The two red arrows in the figure represent the right edge of the bottom layer and the left edge of the face layer. The middle layer: walk 1-0 / 3-4 / / , 3-4 / 1-0 / / against each other, and the plane stress will arch to form an arch bridge effect. The arch bridge effect of the face layer and the bottom layer can be designed to achieve different spacing arch bridge effects in theory. However, due to the limitation of the guide bar, it is currently not possible to achieve continuous and different arch bridge effects (i.e., different arch bridge heights) on the same fabric pattern. In addition, due to the limitation of the horizontal movement of the existing warp knitting equipment and actual verification, the maximum needle span should not exceed 1-0 / 8-9 / / , 8 needle spacings, and the arch bridge effect pattern width cycle is 16 columns, and the arch bridge effect pattern column width is 2 times the number of needle spacings.

[0074] In the three-dimensional warp-knitted fabric with the structure of the present application, the face layer is knitted by nylon monofilament yarn and located at the upper part of the mesh cloth, having good air permeability and permeability. The face layer is specially designed with arch bridge effect patterns, which not only enhances the visual beauty but also provides additional support and comfort. The middle layer includes jacquard columns composed of TPEE monofilament yarn, which forms a double S arch bridge wave effect through the face layer and the bottom layer, enhancing the overall three-dimensionality and visual effect. The double S arch bridge wave effect is hollow inside, increasing the cushioning effect and providing additional softness and comfort, effectively reducing pressure points and improving the wearing experience. The bottom layer is knitted by nylon monofilament yarn and located at the lower part of the mesh cloth, having good air permeability and permeability. The face layer is specially designed with arch bridge effect patterns, which not only enhances the visual beauty but also provides additional support and comfort.

[0075] Example 2: Unequal Spacing Arch Bridge Wave Effect

[0076] The fabric structure of the present application is based on the changes of Example 1, the difference is that the spacing of the arch wave shape is not equal, the manufacturing process includes the following steps:

[0077] S1: Setting the guide bar: At least 6 guide bars are set on the warp knitting equipment, from the front needle bed to the back needle bed, including ground comb guide bar GB1, ground comb guide bar GB2, ground comb guide bar GB3, ground comb guide bar GB4, ground comb guide bar GB5, and ground comb guide bar GB6.

[0084] Bottom layer:

[0085] GB5: N-DT 0.10 / 1 F nylon bright (83D / 1 F) yarns 6 hank heads of 410 ends each, GB1: N-DT 0.10 / 1 F nylon bright (83D / 1 F) content around 17.77%.

[0086] GB6: N-DT 0.10 / 1 F nylon bright (83D / 1 F) yarns 6 hank heads of 410 ends each, GB6: N-DT 0.10 / 1 F nylon bright (83D / 1 F) content around 17.77%.

[0097] S4 weaving: wherein the face layer:

[0098] GB1: warp knitting basic organization 1-0 / 1-2 / / ;

[0099] GB2: warp knitting basic organization 1-2 / 1-0 / / ;

[0100] Middle layer:

[0103] Bottom layer:

[0104] GB5: warp knitting basic organization 1-2 / 1-0 / / ;

[0105] GB6: warp knitting basic organization 1-2 / 1-0 / / .

[0106] S5 heat treatment:

[0107] The fabric obtained by weaving is subjected to high-temperature setting, the temperature is 100℃, the time is 1h, after high-temperature setting, the molecular chain rearrangement can fix the wave jacquard structure, and ensure the long-term stability of the air permeation pore. The heat treatment process can also be combined with the fabric dyeing process, that is, the setting effect is realized by means of high-temperature fixing baking after fabric dyeing.

[0108] The yarn laying motion in the above manufacturing process is shown in Figure 4 , in the figure, the face layer and the bottom layer are symmetrically parallel to the yarn, in the figure, the two intersecting arrows represent the right edge of the bottom layer and the left edge of the face layer, the middle layer: 1-0 / 1-2 / / , 1-2 / 1-0 / / are pulled against each other, the plane stress will arch to form an unequal spacing arch wave effect.

[0109] In this embodiment, the face layer and the bottom layer are continuous unequal-interval arch bridge waves, and the length and shortness of the arch bridge waves are matched with the change of the threading sequence of the comb guide holes, so that arbitrary design can be performed, and for example, the same cloth sample can also realize the effect of continuous unequal-interval gradual change.

[0110] In the warp-knitted fabric of the three-dimensional pair-drawing structure, the face layer is knitted by polyamide monofilament yarn and is located at the upper part of the mesh cloth, and has good air permeability and permeability. Since the face layer and the bottom layer are symmetrically parallel to the yarn, this parallel symmetry can generate a half-cavity cylindrical effect between the face layer and the bottom layer, which not only enhances the visual aesthetics, but also provides additional support and comfort. The intermediate layer includes jacquard columns composed of TPEE monofilament yarn. Due to the unequal-interval arch bridge waves, the face-bottom pair-drawing forms a cavity cylindrical effect with varying sizes, enhancing the overall three-dimensionality and visual effect. Moreover, the cavity cylinder increases the cushioning effect, providing additional softness and comfort, effectively reducing pressure points and improving the wearing experience.

[0111] Embodiment 3: (Hollow 3D three-dimensional effect)

[0112] The fabric structure of this embodiment is changed based on Embodiment 1, and the difference lies in that the face layer is a hollow 3D three-dimensional effect, and its manufacturing process includes the following steps:

[0113] S1: Setting the guide bar: setting the guide bar of the warp-knitting equipment, including at least 7 guide bars, from the front needle bed to the back needle bed, ground comb guide bar GB1, ground comb guide bar GB2, ground comb guide bar GB3, ground comb guide bar GB4, ground comb guide bar GB5, ground comb guide bar GB6, and ground comb guide bar GB7.

[0145] S5 heat treatment:

[0146] The woven fabric is subjected to high temperature setting, the temperature is 110°C, the time is 1h, after high temperature setting, the molecular chain rearrangement can fix the wave jacquard structure, ensure the long-term stability of the air permeation pore. The heat treatment process can also be combined with the fabric dyeing process, that is, the setting effect is realized by means of high temperature fixing and baking after fabric dyeing.

[0147] The yarn lapping motion in the above manufacturing process is shown in Figure 5 , and the product structure is shown in Figure 6 . The warp-knitted fabric with three-dimensional counter-pulling structure includes a face layer 1, an intermediate layer 2 and a bottom layer 3, wherein the face layer 1 includes a plurality of face layer yarns, the face layer yarns are looped and woven to form the face layer 1; the bottom layer 3 includes a plurality of bottom layer yarns, the bottom layer yarns are looped and woven to form the bottom layer 3; the intermediate layer 2 is formed by the cross-pulling of part of the face layer yarns and part of the bottom layer yarns to form a plurality of connecting parts, the connecting parts are located between the face layer and the bottom layer, and have a cavity structure 5. Specifically, the face layer 1 and the bottom layer 3 each include a plurality of continuously arranged arch-shaped structures, and the face layer 1 and the bottom layer 3 are 3D three-dimensional mesh fabrics, which have uniformly distributed pores 4.

[0148] Compared with example 1, the face layer of the present example has one more guide bar walking 0-0 / 2-2 (in other cases, the bottom layer can also have one more guide bar walking 2-2 / 0-0 / / ), which links the independent vertical columnar pillars to make them into an overall plain effect.

[0149] The warp-knitted fabric with the three-dimensional pair structure has a special undulating corrugated effect in the middle layer, which greatly improves the heat exchange effect when applied to a shoe upper, can increase the contact area with fluid medium, and improves the heat exchange efficiency; the face layer, the middle layer and the bottom layer cooperate with each other to form a louver effect, which is not only beautiful but also can effectively guide air flow, improve air permeability and comfort. Due to the hollow 3D three-dimensional effect of the face layer, the fabric also has a buffering effect inside, providing additional softness and comfort, effectively reducing pressure points and improving the wearing experience.

[0150] The present example is based on the process upgrading and optimization of example 1. The local hollow effect is realized by changing the process of the middle layer: GB4, GB5. After the porosity of the hollow area is improved, the air contact area is increased, the arched structure guides the airflow to strengthen the heat exchange, and the face and bottom are linked through (3-4 / 2-1)*4 / short span needle part to realize local hollow. In addition, the louver effect: through the alternative weaving of GB4 / GB5, local 45° inclined stripes are formed, and the light transmittance and privacy are controlled.

[0151] Therefore, the fabric in the present example has a unique arched bridge structure effect and a local louver effect, which is not only beautiful but also can effectively guide air flow.

[0152] In the present example, the middle layer (3-4 / 1-0)*4 / long span needle part links the face and bottom, realizes the dense non-hollow part, and the face and bottom guides are synchronized and reverse lapping (GB4 and GB5 complementary interweaving), which is beneficial to improve the mesh physical property, tear strength, and is suitable for the stress part of the shoe upper.

[0153] In other examples, by adjusting the span needle ratio (such as dense area and hollow area) of the middle layer, the air permeability and strength demand can be further balanced.

[0154] In the present example, the light reflectivity of TPEE bright monofilament and nylon bright filament is consistent, which ensures the uniformity of the visual quality of the shoe upper and avoids the influence of the appearance grade caused by the light reflection difference of the materials.

[0155] In summary, the fabric of the present embodiment, on the basis of having the product advantage effect in Example 1, cooperates with the thermoplastic monofilament material, after high-temperature dyeing and setting, gives the hollow 3D jacquard layer excellent resilience, high-temperature setting, rearrangement of molecular chain, fixation of wave jacquard structure, and ensures the long-term stability of the air permeation pore. Through the intermediate layer: adjusting the cross-needle ratio (such as dense area and hollow area) can further balance the air permeability and strength demand. If non-elastic material is used, there is no unique arch bridge structure effect and local louver effect after high-temperature dyeing and setting.

[0157] The present embodiment is changed on the basis of Example 3, the difference lies in that: the face layer 3D body is provided with holes with different densities, and the intermediate layer is a partition connection effect.

[0231] GB8: Warp-knitted base structure 1-2 / 1-0 / / ;

[0232] S5 heat treatment:

[0233] The woven fabric is subjected to high-temperature setting at a temperature of 130°C for 1 h. After high-temperature setting, the molecular chain is rearranged, the wave jacquard structure can be fixed, and the long-term stability of the air permeation pore is ensured. The heat treatment process can also be combined with the fabric dyeing process, that is, the setting effect is realized by means of high-temperature fixing baking after fabric dyeing.

[0234] The manufacturing process of Example 4 and Example 5 is a process advanced version based on Example 3, and the Jacquard technology is innovatively added for free opening design, thereby realizing the single Jacquard opening hollow 3D jacquard effect. In Example 1, the threading mode is 9 threads and 1 empty. This relatively fixed threading mode has certain limitations when responding to customer's demand for product detail adjustment. For example, when the customer temporarily proposes to adjust the width of the surface layer column or the width of the arch bridge effect, the traditional warp knitting process needs to be re-derived with complex process. This process not only consumes a lot of manpower, but also requires professional technicians to recalculate and design the threading mode, needle method, etc.; it also causes waste of material resources, such as the need to prepare yarns and adjust machine parameters again, resulting in increased production cost and prolonged production cycle.

[0235] After the introduction of Jacquard technology in Example 4 and Example 5, the situation has been greatly improved. The Jacquard drawing board cooperates with reasonable needle method, making the design of the width of the surface layer column more flexible. Within a reasonable process range, the width of the column and the width of the arch bridge effect can be quickly and conveniently adjusted according to the specific needs of the customer. At the same time, the Jacquard technology can be used to appropriately open holes, which further improve the air permeability and air flow of the mesh fabric. When wearing the upper made of the mesh fabric, the heat generated by the feet can be more smoothly discharged through these holes, and fresh air from the outside can also more easily enter, thereby effectively improving the comfort of wearing and avoiding the discomfort caused by heat.

[0236] Case 6: (Single Jacquard on pull opening hollow 3D effect)

[0237] This example is changed based on Example 4, the difference is that the circular holes with different densities are arranged between the surface layer 3D bodies, and the circular holes are formed by pulling.

[0238] The manufacturing process comprises the following steps:

[0239] S1: Setting the guide bars of the warp knitting machine, at least including 7 guide bars, from the front needle bed to the back needle bed, ground bar GB1, Jakard bar JK2, Jakard bar JK3, ground bar GB4, ground bar GB5, ground bar GB6, ground bar GB7.

[0306] S5 Heat treatment:

[0307] The woven fabric is subjected to high-temperature setting at a temperature of 180°C for 1 hour. After high-temperature setting, the molecular chain rearranges, which can fix the wave jacquard structure and ensure the long-term stability of the air permeation pores. This heat treatment process can also be combined with the fabric dyeing process, that is, by means of high-temperature fixing and baking after fabric dyeing, the setting effect is achieved.

[0308] Examples 6 and 7 are another technical upgrade based on Examples 4 and 5, introducing the Jacquard counter draw process. The application of this process greatly enriches the pattern design of the mesh fabric, bringing more creativity and change space to the product. Jacquard counter draw process controls the Jacquard device, so that the yarn can realize more complex interlacing mode in the weaving process. In the intermediate layer, the yarns of GB4 and GB5 form a unique pattern under the action of the Jacquard counter draw process. This pattern not only looks more beautiful and unique in appearance, but also has certain functionality. From the perspective of appearance, the rich and varied patterns can meet the individual needs of different customers for the appearance of the upper. Whether it is a consumer who pursues fashion trends or a brand that values the uniqueness of the product, they can find a style that meets their needs from these rich and varied pattern designs.

[0309] In terms of functionality, the jacquard process further optimizes the air permeability and mechanical properties of the mesh fabric. By adjusting the density and distribution of the patterns, the air permeability of different areas of the mesh fabric can be precisely controlled, allowing the upper to have better air permeability in key areas such as the toes and soles, where sweating is more likely to occur. At the same time, the complex pattern structure enhances the internal interlacing strength of the mesh fabric, improving the overall stability and anti-deformation ability of the mesh fabric. Even in the case of long-term wear and frequent activities, the upper can maintain good shape and performance, providing more reliable support and comfortable experience for the wearer.
