Description

Technical Field

[0001] This application relates to the field of textile technology, and in particular to a fabric and shoe upper with dynamic light and shadow effects. Background Technology

[0002] In the textile industry, fabrics with unique visual effects are increasingly favored in apparel, home décor, and high-end industrial applications. Traditional glossy fabrics typically achieve their reflective effect through single-yarn weaving or post-treatment coating processes. While these methods can produce a certain level of reflectivity, they often lack depth and dynamic variation, particularly in creating nuanced contrasts of light and shadow under illumination. Traditional reflective fabrics, on the other hand, typically use reflective yarns and coatings, resulting in pollution and high labor costs. Furthermore, reflective materials are not conducive to fabric weaving, cannot adapt to equipment requirements, and the yarns cannot be dyed later, leading to high costs. Additionally, reflective materials are easily damaged by friction and repeated washing. Moreover, existing multi-layered fabric structures primarily focus on functionality (such as breathability and warmth) while paying less attention to innovative designs that enhance optical aesthetics.

[0003] Currently, some warp knitting techniques can achieve pattern variations through jacquard weaving, but most are still limited to static representations of flat patterns. They cannot combine the characteristics of the yarn itself with structural design to achieve dynamic light and shadow effects that change with viewing angle or lighting. In addition, traditional mesh fabrics usually only focus on breathability and fail to synergize with the underlying optical design, resulting in a monotonous visual appearance. Utility Model Content

[0004] In order to solve one or more of the technical problems existing in the prior art, the embodiments of this application provide a fabric with dynamic light and shadow effects, a method for manufacturing the same, and a shoe upper, so as to solve the problems of traditional fabrics having a single visual expression and lacking innovative designs with optical aesthetics.

[0005] To achieve the above objectives, the technical solution adopted by this application to solve its technical problem is as follows: In a first aspect, this application provides a fabric with dynamic light and shadow effects, the fabric comprising: The first woven layer is configured such that at least a portion of its area forms a first mesh structure; The second woven layer is configured to include an alternating first region and a second region, wherein the brightness of the first region is higher than that of the second region, the first region is woven from a first bright yarn, and the position of the first mesh structure corresponds to at least a portion of the first region and at least a portion of the second region. A third braided layer is configured to be connected between the first braided layer and the first braided layer.

[0006] In this application, on the one hand, the first mesh structure on the first woven layer and the interlaced first and second regions on the second woven layer work together. Since the first region is woven with the first bright yarn, it can create a visual effect of some areas being highlighted and others being opaque. Moreover, as the viewing angle or lighting conditions change, the fabric presents dynamic light and shadow changes of alternating brightness and darkness, enhancing the visual three-dimensionality and artistic expression. On the other hand, the first mesh structure gives the fabric excellent breathability and lightweight properties, making it suitable for various application scenarios such as fashion and sportswear.

[0007] In one specific embodiment, the first region is formed as the woven bottom layer of the second woven layer, and the second region covers a portion of the first region to form the surface jacquard of the second woven layer; or... The second region forms the woven bottom layer of the second woven layer, and the first region covers a portion of the second region to form the surface jacquard of the second woven layer.

[0008] This application's solution, by flexibly configuring the hierarchical relationship between the first and second regions, can achieve two different jacquard effects under the same weaving process, giving the fabric a richer visual expression and realizing diversified design of the fabric structure.

[0009] In one specific embodiment, the braided underlayer includes a base structure and / or a second mesh structure.

[0010] The present application scheme configures the woven bottom layer as a basic structure and / or a second mesh structure. When the woven bottom layer adopts a basic structure (such as plain weave or twill weave), it can provide stable mechanical support and shielding. When the woven bottom layer adopts a second mesh structure, it provides the fabric with two-way air permeability channels, forming a three-dimensional ventilation system with the first mesh structure of the first woven layer, which significantly improves heat dissipation performance, thereby achieving synergistic optimization of fabric function and structure.

[0011] In one specific embodiment, the first woven layer is formed by weaving a second bright yarn; The second region of the second woven layer is formed by weaving with a third bright yarn; The third woven layer is formed by weaving with a fourth bright yarn; The first bright yarn has a higher gloss than the second, third and fourth bright yarns.

[0012] This application solution achieves precise control of the fabric's optical effects and a three-dimensional presentation of visual layers through a multi-layered weaving structure combined with a configuration of bright yarns with differentiated luster.

[0013] In one specific embodiment, the fineness of the first, second, third, and fourth bright yarns is 50-300D.

[0014] In one specific embodiment, the first bright yarn is a bright polyester yarn; and / or, The second bright yarn and / or the fourth bright yarn are CD bright yarns; and / or, The third bright yarn is a nylon bright yarn.

[0015] This application achieves precise control of the optical properties of fabrics through a material combination of differentiated bright yarns.

[0016] In one specific embodiment, the mesh shape of the first mesh structure is circular or any kind of polygon.

[0017] The proposed solution achieves synergistic optimization of fabric function and aesthetics by flexibly designing the shape (circle or polygon) of the first mesh structure.

[0018] In one specific embodiment, the first region and / or the second region includes at least one of a geometric pattern, gradient stripes, or random dotted distribution.

[0019] The proposed solution achieves a diverse range of visual effects and flexible functional adaptation of the fabric by designing geometric patterns, gradient stripes, or random dotted distributions in the first and / or second areas.

[0020] In one specific embodiment, the first braided layer is configured to be formed by the combination of a first comb and a first jacquard. And / or, The second braided layer is configured such that the first region is formed by the second comb and the second region is formed by the second jacquard, or the first region is formed by the second jacquard and the second region is formed by the second comb. And / or, The third braided layer is configured to be formed by a third comb.

[0021] This application solution achieves precise control of the fabric structure through the coordinated weaving configuration of multiple combs and jacquards.

[0022] In one specific embodiment, the first region is formed by a second comb and a third jacquard weave, and the second region is formed by a second jacquard weave; Alternatively, the first region may be formed by a second jacquard weave, and the second region may be formed by a second comb and a third jacquard weave.

[0023] Secondly, this application also provides a shoe upper, which is made of fabric, including the fabric with dynamic light and shadow effects described in any one of the first aspects. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] As described in the background section, traditional fabrics suffer from problems such as monotonous visual presentation and a lack of innovative designs with optical aesthetics. To address one or more of these issues, this application proposes a novel fabric with dynamic light and shadow effects. This fabric achieves a visual effect where a first mesh structure on a first woven layer interacts with a first area formed by the weaving of a first bright yarn on a second woven layer. This creates a visual effect where some areas are highlighted with light, while others are opaque and translucent. Furthermore, as the viewing angle or lighting conditions change, the fabric exhibits dynamic light and shadow variations, enhancing its visual depth and artistic expression. In addition, the first mesh structure provides the fabric with excellent breathability and lightweight properties, making it suitable for various applications such as fashion apparel and sportswear.

[0028] The solution of this application will now be described in detail with reference to the accompanying drawings and various embodiments.

[0029] Example 1 To achieve the solution of this application, an embodiment of this application provides a fabric with dynamic light and shadow effects, referring to... Figures 1 to 3 As shown, the fabric includes a first woven layer 100, a second woven layer 200, and a third woven layer 300 connecting the first woven layer 100 and the second woven layer 200. At least a portion of the first woven layer 100 forms a first mesh structure 110. The second woven layer 200 includes alternating first regions 210 and second regions 220. The brightness of the first region 210 is higher than that of the second region 220. The first region 210 is woven with a first bright yarn. The position of the first mesh structure 110 corresponds to at least a portion of the first region 210 and at least a portion of the second region 220. Through the interaction of the first mesh structure on the first woven layer and the alternating first and second regions on the second woven layer, and because the first region is woven with the first bright yarn, a visual effect of partial highlighting and partial opaque transparency can be created. Furthermore, as the viewing angle or lighting conditions change, the fabric exhibits dynamic light and shadow changes, enhancing visual three-dimensionality and artistic expression. In addition, the first mesh structure 110 gives the fabric excellent breathability and lightweight properties, making it suitable for various applications such as fashion and sportswear.

[0030] It should be noted that, in the embodiments of this application, the specific hierarchical relationship of the first braided layer 100, the second braided layer 200, and the third braided layer 300 is not specifically defined. For example, in some specific embodiments, the first braided layer 100 is the surface layer of the fabric, the second braided layer 200 is the bottom layer of the fabric, and the third braided layer 300 is the middle layer of the fabric; in other specific embodiments, the third braided layer 300 is the surface layer of the fabric, the second braided layer 200 is the bottom layer of the fabric, and the first braided layer 100 is the middle layer of the fabric.

[0031] In some specific embodiments, the third woven layer 300, serving as an intermediate layer, interweaves and connects the first woven layer 100 and the second woven layer 200 to form a stable three-dimensional structure. For example, when the fabric is a shoe upper fabric, the third woven layer 300 can adopt a V-shaped jacquard weave to connect the first woven layer 100 and the second woven layer 200, achieving a balance between stiffness and comfort.

[0032] The following description uses the first braided layer 100 as the surface layer of the fabric, the second braided layer 200 as the bottom layer of the fabric, and the third braided layer 300 as the middle layer of the fabric as examples to illustrate the solution of this application.

[0033] In some specific embodiments, both the first region 210 and the second region 220 are highlight regions, and the brightness of the first region 210 is higher than that of the second region 220. In some other specific embodiments, the first region 210 is a highlight region, and the second region 220 is a soft light region or a shadow region.

[0034] In some specific embodiments, the first mesh structure 110 is provided with different density distributions at different positions of the first braided layer 100. Combined with the first region 210 formed by the second braided layer 200 using the first bright yarn, light can be focused and reflected when passing through specific mesh openings, rather than being uniformly diffused, thereby improving the contrast of light and shadow.

[0035] It should be noted that, in this embodiment, the relative positions of the first region 210 and the second region 220 are not specifically limited. The hierarchical relationship between the first region 210 and the second region 220 can be flexibly configured according to actual needs. Thus, by interchanging the hierarchical positions of the first region 210 and the second region 220, two different jacquard effects can be achieved under the same weaving process, giving the fabric a richer visual expression. For example, when the brighter first region 210 is used as the weaving bottom layer, the lower-brightness second region 220 is used as the surface jacquard to form an overlay pattern; conversely, a transparent light and shadow contrast is presented.

[0036] In some specific embodiments, a first region 210 with higher brightness can be used as the bottom layer of the second woven layer 200, and a second region 220 with lower brightness can be used as the top layer of the second woven layer 200, covering a portion of the first region 210 with jacquard weave. Figure 2 As shown.

[0037] In other specific embodiments, a lower-brightness second region 220 can be used as the underlayer of the second woven layer 200, and a higher-brightness first region 210 can be used as the top layer of the second woven layer 200, covering a portion of the second region 220 with jacquard weave. Figure 3As shown.

[0038] In some specific embodiments, the woven bottom layer adopts a basic structure, such as plain weave or twill weave, which can provide stable mechanical support and shielding, making it suitable for applications requiring high coverage. Furthermore, when the woven bottom layer is a first region 210 formed by the first bright yarn, the reflectivity of the first bright yarn can be enhanced, creating a bright light and shadow area.

[0039] Reference Figure 4 As shown, in some specific embodiments, the woven bottom layer has a second mesh structure 230, which forms a two-way ventilation channel and together with the first mesh structure 110 of the first woven layer 100, forms a three-dimensional ventilation system, significantly improving the heat dissipation and breathability of the fabric. Furthermore, when the woven bottom layer is a first region 210 formed by the weaving of the first bright yarn, the second mesh structure 230 can also create a diffused halo effect through the superposition of multiple mesh layers, softening local highlights.

[0040] In other specific embodiments, the woven bottom layer adopts a structure that combines a basic structure with a second mesh structure, which can ensure stable mechanical support and shielding while improving the heat dissipation and breathability of the fabric.

[0041] In some specific embodiments, the first braided layer 100 is formed by weaving with a second bright yarn, the second region 220 of the second braided layer 200 is formed by weaving with a third bright yarn, and the third braided layer 300 is formed by weaving with a fourth bright yarn. The first bright yarn has a higher gloss than the second, third, and fourth bright yarns. It is understood that gloss is a physical quantity that evaluates the ability of a material surface to reflect light under a set of geometrically defined conditions; that is, gloss characterizes the ability of a material's surface to reflect light when illuminated.

[0042] Specifically, the first woven layer 100, serving as the surface layer of the fabric, controls light transmittance through the first mesh structure 110. Therefore, the second bright yarn used in the first woven layer 100 can have a lower gloss level. The second woven layer 200 employs an alternating arrangement of first and second regions. The first region uses a first bright yarn with higher gloss, while the second region uses a third bright yarn with lower gloss, creating a contrast between light and dark areas. The third woven layer, serving as the base layer, uses a fourth bright yarn with lower gloss, providing uniform diffuse reflection and preventing overexposure of the underlying layers.

[0043] It should be noted that by layering and combining the first glossy yarn (high gloss) with the second / third / fourth glossy yarns (low gloss), a distinct gradient of light and shadow is created: the high gloss yarn acts as the visual focus, highlighting local bright spots, while the low gloss yarn forms a soft background, enhancing the overall three-dimensionality. Furthermore, the yarns of different gloss levels produce varying reflection intensities when the fabric is bent or the angle of light changes; for example, the high gloss area displays a jumping light spot, while the low gloss area maintains a hazy reflection, thus achieving a dynamic visual effect of "flickering-gradient."

[0044] In some specific embodiments, the first bright yarn is a bright polyester yarn; and / or, The second bright yarn and / or the fourth bright yarn are CD bright yarns; and / or, The third bright yarn is a nylon bright yarn.

[0045] Specifically, the first bright yarn is a polyester bright yarn, the second and fourth bright yarns are CD bright yarns, and the third bright yarn is a nylon bright yarn. The polyester bright yarn (first bright yarn), with its high reflectivity, serves as the main light source reflective layer, creating a localized strong mirror-like flash effect on the second braided layer 200. The CD bright yarn (second / fourth bright yarn), through its unique angle-changing color effect, produces iridescent gradients or dynamic color-changing spots on the fabric surface, enhancing visual interest. The nylon bright yarn (third bright yarn) provides soft diffused light, forming a light-dark transition buffer zone with the highlight areas, avoiding excessive optical contrast. In summary, this application's solution achieves multi-dimensional optical response by employing different types of bright yarns. In addition, polyester has high strength, which, combined with the optical activity of CD yarn, ensures both the fabric's abrasion resistance and intelligent color development. Meanwhile, nylon's elastic recovery can compensate for the brittleness of CD yarn and improve the fabric's deformation durability.

[0046] It should be noted that the fineness of each bright yarn is not specifically limited in the embodiments of this application. Without departing from the inventive concept of this application, it can be selected according to actual product requirements. For example, the fineness of the first, second, third, and fourth bright yarns can be any value between 50 and 300D. Exemplarily, the fineness of the first, second, third, and fourth bright yarns can be 50D, 100D, 150D, 200D, 250D, 300D, etc., and will not be listed exhaustively here.

[0047] As an illustrative and not limiting description, the first bright yarn may be 150D / 48F polyester bright yarn, the second bright yarn may be 150D / 48F CD bright yarn, the third bright yarn may be 140D / 48F nylon bright yarn, and the fourth bright yarn may be 30D / 1F CD bright yarn.

[0048] It should be noted that the shape and size of the first mesh structure 110 are not specifically limited in this embodiment. Without departing from the inventive concept of this application, they can be set according to actual product requirements. In some specific embodiments, the mesh shape of the first mesh structure 100 can be circular or any kind of polygon.

[0049] In some specific embodiments, the first mesh structure 100 adopts circular mesh openings. When light passes through these circular mesh openings, it can produce a soft, diffused halo, forming a natural gradient light and shadow effect. Furthermore, the circular mesh openings have a uniform stress distribution when stretched, making them more suitable for scenarios requiring high elasticity. Further, polygonal mesh openings are arranged in a directional manner on the first woven layer 100, such as a rhombus tilted at 45°, which can guide light to reflect in one direction, achieving a flashing effect at a specific angle.

[0050] In other specific embodiments, the first mesh structure 100 adopts polygonal mesh (such as triangles, hexagons, rhombuses, etc.). The angular structure of polygonal mesh can refract light, producing sharp geometric light spots, enhancing visual impact, and polygonal mesh (such as triangles) can improve the tear resistance of the fabric through corner interlocking.

[0051] In other specific embodiments, the first mesh structure 100 may also employ a combination of circular mesh and polygonal mesh partitions.

[0052] In some specific embodiments, by designing geometric patterns, gradient stripes, or random dotted distributions in the first region 210 and / or the second region 220, the visual effects of the fabric can be diversified and its functionality can be flexibly adapted. Specifically, designing geometric patterns (such as squares, rhombuses, and wave patterns) in the first region 210 and / or the second region 220 can give the fabric a regular decorative aesthetic, which is suitable for structural design needs. Furthermore, the edges of the geometric patterns can refract light, producing sharp light and shadow contrasts. At the same time, the regular arrangement of the geometric patterns can optimize the mechanical properties of the fabric (e.g., the rhombus structure improves tensile strength). Designing gradient stripes in the first region 210 and / or the second region 220 can create a soft visual transition through gradual changes in the density or color of the gradient stripes, enhancing the dynamic sense of layering. The light transmittance can also be controlled by varying the density of the gradient stripes, achieving a gradual change in light from dense to sparse or from sparse to dense. Designing random dotted patterns in the first region 210 and / or the second region 220 can simulate natural textures (such as starry skies and water ripples), enhancing the artistry and uniqueness of the fabric. Furthermore, combining random dotted patterns with glossy yarns can create staggered local reflections, enhancing the three-dimensional effect.

[0053] It should be noted that the fabric with dynamic light and shadow effects provided in this application embodiment can be integrally formed using a double-needle bed multi-jaccha warp knitting machine. Through the coordinated knitting configuration of multiple guide bars and jacquards, precise control of the fabric structure and optimization of functional zoning are achieved. Complex light and shadow effects can be achieved without post-processing, reducing production costs. It is understood that jacquard programming can quickly adjust the mesh size and the distribution of bright yarns to meet personalized customization needs and is suitable for small-batch, multi-variety production.

[0054] In some specific embodiments, the first braided layer 100 is configured to be formed by the combination of a first comb and a first jacquard. And / or, The second braided layer 200 is configured such that the first region 210 is formed by the second comb and the second region 220 is formed by the second jacquard, or the first region 210 is formed by the second jacquard and the second region 220 is formed by the second comb. And / or, The third braided layer 300 is configured to be formed by the third comb.

[0055] The fabric with dynamic light and shadow effects provided in this application embodiment is formed by a three-bar double jacquard weave. Exemplarily, the first bar uses GB1, the second bar uses GB7, the third bar uses GB2, the first jacquard uses JB1.1 and JB1.2, and the second jacquard uses JB2.1 and JB2.2. In specific implementation, GB1 is woven in combination with JB1.1 and JB1.2 to form the first woven layer 100, GB7 is woven in combination with JB2.1 and JB2.2 to form the second woven layer 200, and GB2 is woven to form the third woven layer 300. Specifically, a first region 210 with higher brightness can be formed using GB7 weaving as the bottom layer of the second woven layer 200, and a second region 220 with lower brightness can be formed using JB2.1 and JB2.2 weaving to cover a portion of the first region 210 as the surface jacquard of the second woven layer 200; or, a second region 220 with lower brightness can be formed using GB7 weaving as the bottom layer of the second woven layer 200, and a first region 210 with higher brightness can be formed using JB2.1 and JB2.2 weaving to cover a portion of the second region 220 as the surface jacquard of the second woven layer 200.

[0056] Furthermore, the first region 210 is formed by the second comb and the third jacquard weave, and the second region 220 is formed by the second jacquard weave; Alternatively, the first region 210 is formed by the second jacquard weaving, and the second region 220 is formed by the second comb and the third jacquard weaving.

[0057] The fabric with dynamic light and shadow effects provided in this application embodiment is formed by using a three-comb, three-jac weave. Exemplarily, based on the above, third jacquards JB3.1 and JB3.2 are added. In specific implementation, GB7 can be used in conjunction with JB3.1 and JB3.2 to form a first region 210 with higher brightness, and JB2.1 and JB2.2 can be used to form a second region 220 with lower brightness, covering a portion of the second region 220; or, JB2.1 and JB2.2 can be used to form a first region 210 with higher brightness, and GB7 can be used in conjunction with JB3.1 and JB3.2 to form a second region 220 with lower brightness, covering a portion of the second region 220.

[0058] The following describes the solution of this application with two specific embodiments.

[0059] Case 1: The fabric, featuring dynamic light and shadow effects, is created using a three-comb double jacquard weave, as detailed below: For the first braided layer 100: The first guide bar uses GB1 warping with 150D / 48F CD bright white low-elasticity lightweight mesh (i.e., the second bright yarn), with a full needle bed count of 3072 stitches. It has 6 bobbins divided into 3 fabric widths (i.e., 1024 stitches per width with 2 bobbins per width). The GB1 yarn is threaded on the machine in a full-thread manner, with a warp feed of 1600mm / lacquer. The CD yarn content of GB1 is approximately 16.211%. For example, the GB1 weave pattern 1-0 / 1-1 / 0-1 / 1-1 / / chain braids acts as a fixing mechanism to control weft skew and also serves as a bottom-layer support skeleton, providing a foundation for jacquard weave. The chain braid structure (main chain 1-1 / 0-1) creates longitudinal locking force to suppress weft skew (preventing fabric skewing), while the alternating lateral shifts (1-0 and 0-1 alternations) enhance lateral stability and prevent loop twisting.

[0060] The first jaka, JB1.1 and JB1.2, are knitted simultaneously with one thread and one empty stitch, totaling 1536 stitches. The 6 spools are divided into 3 pieces of fabric (i.e., one piece of fabric has 2 spools and 512 stitches; JB1.1 and JB1.2 form a whole jaka, resulting in a full stitch count). Among them, JB1.1 warping 150D / 48F CD bright low-elasticity lightweight yarn (i.e., the second bright yarn) has 6 heads and 256 yarns. JB1.1 yarn is threaded on the machine in a 1-thread-1-empty-yarn pattern, with a warp feed of 2300MM / Rag. The CD ratio of JB1.1 is about 11.651%. JB1.2 warping 150D / 48F CD bright low-elasticity lightweight yarn has 6 heads and 256 yarns. JB1.2 yarn is threaded on the machine in a 1-thread-1-empty-yarn pattern, with a warp feed of 2300MM / Rag. The CD ratio of JB1.2 is about 11.651%.

[0061] For example, JB1.1 and JB1.2 use a variation weave 1-0 / 1-1 / 1-2 / 1-1 / / to form the base weave. An elastic mesh base is achieved through alternating back-needle shifts (1-2) and front-needle padding (1-0). The Jacquard variation weave thick plain weave padding is 1-0 / 1-1 / 2-3 / 1-1 / / to form a thick plain weave, achieving high-density coverage (2-3 large needle spacing shifts) and strong light-blocking properties. The thin plain weave padding is 1-0 / 1-1 / 1-2 / 1-1 / / to form a thin plain weave with medium density and partial light transmission. The mesh padding is 2-1 / 1-1 / 1-2 / 1-1 / / , forming openings through 2-1 skipped stitches to improve the fabric's breathability.

[0062] The first woven layer 100 is woven with a surface mesh plain fabric using GB1, JB1.1, and JB1.2. The mesh design has a certain degree of permeability, allowing the observer to clearly see the underlying structure through the surface mesh. This process improves precision and ensures accurate correspondence between the surface mesh and the bottom smooth yarn.

[0063] For the second braided layer 200: The second jacquard, JB2.1 and JB2.2, simultaneously knits 1536 stitches on a one-through-one-empty needle bed. Six bobbins are used across three fabric widths (one width has two bobbins and 512 stitches; JB2.1 and JB2.2 form a single jacquard, resulting in a full needle bed count). The second jacquard, JB2.1 and JB2.2, knits together to form the second area 220, which serves as the jacquard surface layer of the second knitting layer 200. JB2.1 uses a 140D / 48F nylon high-elastic mid-net (i.e., the third bright yarn) with 256 yarns across six bobbins. The JB2.1 yarn is threaded on the machine using a one-through-one-empty-yarn threading method, with a warp feed of 2400mm / lap. The nylon content of JB2.1 is approximately 11.348%. JB2.2 warping 140D / 48F nylon high-elasticity core (i.e., the third bright yarn), 6 warp heads, 256 yarns. JB2.2 yarn is threaded on the machine in a 1-thread-1-empty-yarn threading method, with a warp feed of 2400MM / lact. The nylon content of JB2.2 is about 11.348%.

[0064] For example, JB2.1 and JB2.2 use a variation weave of 1-1 / 1-0 / 1-1 / 1-2 / / , controlling yarn coverage through needle back lateral movement (1-0, 1-2) to achieve a transition in thickness. The surface layer thick plain weave padding weave is 1-1 / 1-0 / 1-1 / 2-3 / / , forming a thick plain weave, which enhances coverage by increasing needle front lateral movement. The thin plain weave padding weave is 1-1 / 1-0 / 1-1 / 1-2 / / , forming a thin plain weave, which reduces yarn density and allows for localized light transmission. The mesh padding weave is 1-1 / 2-1 / 1-1 / 1-2 / / , creating perforations through needle back skipping. The surface layer single-row jacquard padding weave is 2-1 / 1-1 / 1-2 / 1-1 / / , forming a single-row jacquard, achieving localized pattern protrusion.

[0065] The second guide bar uses GB7 warping 150D / 48F polyester bright yarn (i.e., the first bright yarn) to form the first region 210, which serves as the bottom layer of the second knitting layer 200. The full needle bed count is 3072 stitches, with 6 warp heads divided into 3 fabric widths (i.e., one fabric width with 2 warp heads and 1024 stitches). The 6 warp heads contain 512 yarns. The GB7 yarn is threaded onto the machine in a full-thread manner, with a warp feed of 2470 mm / gram. The proportion of whole polyester yarn in GB7 is approximately 25.025%. For example, the GB7 weave pattern is 1-1 / 1-0 / 1-1 / 2-3 / / , forming a dense structure to "lock the bottom."

[0066] GB7 has a total of 3072 needle beds, which is a full needle bed configuration. Each piece of fabric is allocated 1024 needles (each piece is completed by 2 needle heads). It adopts a ground comb 1-1 / 1-0 / 1-1 / 2-3 / / padding weave, which not only forms a unique texture, but also enhances the tensile strength and edge stability of the fabric. GB7 forms the fabric structure through a fixed padding path. Its padding digital input is a fixed padding and cannot be changed freely.

[0067] The use of bright polyester yarn in GB7, combined with JB2.1, and the bottom layer of bright nylon yarn in JB2.1, is a padding structure 1-1 / 1-0 / 1-1 / 2-3 / / . The bright polyester yarn in GB7 reflects light through the first mesh structure 110 of the first weave layer 100 or the thin plain weave area, while the thick plain weave area is covered by nylon yarn and is matte, forming a staggered light and shadow effect. Through the treatment of bright and matte in different areas, the overall three-dimensionality and visual impact of the fabric are enhanced.

[0068] For the third braided layer 300: The third guide bar is woven with GB2 warp 30D / 1F CD bright yarn (i.e., the fourth bright yarn), with a full needle bed count of 3072 stitches. It has 6 bobbins divided into 3 fabric widths (i.e., 1 fabric width with 2 bobbins, 1024 stitches), and 6 bobbins with 512 yarns. The GB2 yarn is threaded onto the machine in a full-thread manner, with a warp feed of 6300mm / lap. The CD yarn content of GB2 is approximately 12.766%. For example, GB2 uses a variation weave 1-0 / 0-1 / 0-1 / 1-0 / / , where 1-0 refers to the first row where the yarn moves in front of the needle (forming loops), and 0-1 refers to the second row where the yarn moves behind the needle (not weaving). This repeats to form a symmetrical structure of four rows per cycle. Through alternating loops and weft insertion, an elastic mesh structure is formed, connecting the first knitting layer 100 and the second knitting layer 200 to prevent delamination, creating a bouncy feel and shock absorption.

[0069] Case 2 The difference from Case 1 is that a three-comb, three-jac weave is used to create a fabric with dynamic light and shadow effects, as detailed below: For the first braided layer 100: The first guide bar is woven with GB1 warping 150D / 48F CD bright white low-elasticity light mesh (i.e., the second bright yarn), with a full needle bed count of 3072 stitches. There are 6 heads divided into 3 widths of fabric (i.e., 1 width of fabric with 2 heads and 1024 stitches). The GB1 yarn is threaded on the machine in a full-thread manner, with a warp feed of 1600MM / lact. The proportion of the CD yarn in GB1 is about 11.511%.

[0070] The first jaka, JB1.1 and JB1.2, are knitted simultaneously with one thread and one empty stitch, totaling 1536 stitches. The 6 spools are divided into 3 pieces of fabric (i.e., one piece of fabric has 2 spools and 512 stitches; JB1.1 and JB1.2 form a whole jaka, resulting in a full stitch count). Among them, JB1.1 warping 150D / 48F CD bright low-elasticity lightweight yarn (i.e., the second bright yarn) has 6 heads and 256 yarns. JB1.1 yarn is threaded on the machine in a 1-thread-1-empty-yarn pattern, with a warp feed of 2300MM / Rag. The CD ratio of JB1.1 is about 8.237%. JB1.2 warping 150D / 48F CD bright low-elasticity lightweight yarn has 6 heads and 256 yarns. JB1.2 yarn is threaded on the machine in a 1-thread-1-empty-yarn pattern, with a warp feed of 2300MM / Rag. The CD ratio of JB1.2 is about 8.237%.

[0071] For example, GB1 uses a variation weave of 1-0 / 1-1 / 0-1 / 1-1 / / , while JB1.1 and JB1.2 utilize Jacquard weaving characteristics to freely vary the mesh plain fabric, allowing for dynamic adjustments based on pattern requirements. The surface layer varies in thickness with a plain weave padding weave of 1-0 / 1-1 / 2-3 / 1-1 / / , and in thinness with 1-0 / 1-1 / 1-2 / 1-1 / / . The mesh padding weave weave is 2-1 / 1-1 / 1-2 / 1-1 / / , ranging from tight to loose, supporting local pattern embellishments.

[0072] For the second braided layer 200: The second jacquard weaving, JB2.1 and JB2.2, forms the second zone 220. JB2.1 uses a 140D / 48F nylon high-elasticity core (i.e., the third bright yarn), with 6 warp heads and 256 yarns. The JB2.1 yarn is threaded on the machine using a 1-thread-1-empty-yarn threading method, with a warp feed of 2400mm / razor. The nylon content of JB2.1 is approximately 8.058%. Similarly, JB2.2 uses the same 140D / 48F nylon high-elasticity core (i.e., the third bright yarn), with 6 warp heads and 256 yarns. The JB2.2 yarn is also threaded on the machine using a 1-thread-1-empty-yarn threading method, with a warp feed of 2400mm / razor. The nylon content of JB2.2 is approximately 8.058%.

[0073] For example, JB2.1 and JB2.2 use a variation weave 1-1 / 1-2 / 1-1 / 1-0 / / to form a "warp plain - variation warp pile" composite structure. By alternating the needle back lateral shift (1 stitch and 2 stitches), a lateral elastic modulus of 85-95 N / cm can be achieved. The bottom layer uses variation thick plain weave padding yarns 1-1 / 2-3 / 1-1 / 1-0 / / and thin plain weave padding yarns 1-1 / 1-2 / 1-1 / 1-0 / / to achieve thick and thin plain weave respectively. The bottom layer uses mesh padding yarns 1-1 / 1-2 / 1-1 / 2-1 / / to form a mesh.

[0074] Unlike Case 1, in this case, the second guide bar uses GB9 and the third jacquard yarns JB3.1 and JB3.2 to form the first area 210. Specifically, the second guide bar uses GB9 warping with 150D / 48F bright polyester yarn (i.e., the first bright yarn), with a full needle bed count of 3072 stitches. Six warp heads are used for three fabric widths (i.e., one fabric width has two warp heads, totaling 1024 stitches). The six warp heads have 512 yarns. The GB9 yarn is threaded on the machine using a full-thread method, with a warp feed of 1700mm / gram. The proportion of whole polyester yarn in the GB9 yarn is approximately 12.230%.

[0075] JB3.1 is a 100D / 48F bright polyester yarn (i.e., the second bright yarn), with 6 warp heads and 256 yarns. JB3.1 yarn is threaded on the machine using a 1-thread-1-empty-yarn threading method, with a warp feed of 2400mm / gram. The polyester content of JB3.1 is approximately 17.266%. JB3.2 is also a 100D / 48F bright polyester yarn (i.e., the second bright yarn), with 6 warp heads and 256 yarns. JB3.2 yarn is threaded on the machine using a 1-thread-1-empty-yarn threading method, with a warp feed of 2400mm / gram. The polyester content of JB3.2 is approximately 17.266%.

[0076] JB3.1 and JB3.2 complement the basic function of the ground comb, ensuring both the basic quality of the fabric and improving production efficiency. They enable free-form weaving of plain weave fabric. As Jacquard combs, JB3.1 and JB3.2 can flexibly adjust the padding yarn path according to design requirements, thereby achieving diverse plain weave fabric effects. For example, when JB3.1 and JB3.2 weave plain weaves of varying thicknesses, the light and shadow bright lines texture inside the holes can be seen through the first mesh structure 110 of the first weave layer 110, forming a unique visual effect. The padding yarn structure is 1-1 / 1-0 / 1-1 / 2-3 / / (the light and shadow bright lines are the thickest and most numerous), and 1-1 / 1-0 / 1-1 / 1-2 / / (the light and shadow bright lines are the second thickest). At this time, JB2.1 and JB2.2 weave the mesh of the second weave layer 200, with the padding yarn structure being 1-1 / 1-2 / 1-1 / 2-1 / / . When the JB3.1 and JB3.2 woven mesh structure 1-1 / 2-1 / 1-1 / 1-2 / / is combined with the JB2.1 and JB2.2 woven mesh structure 1-1 / 1-2 / 1-1 / 2-1 / / , the first woven layer 100 and the second woven layer 200, through the combination of the above-mentioned padding yarn structure, present a permeable and breathable effect. This effect not only improves the comfort of the fabric, but also enhances its functionality. When JB2.1 and JB2.2 follow the variation patterns 1-1 / 1-2 / 1-1 / 1-0 / / and 1-1 / 2-3 / 1-1 / 1-0 / / , combined with JB3.1 and JB3.2 following the weaving patterns 1-1 / 1-2 / 1-1 / 1-0 / / and 1-1 / 2-3 / 1-1 / 1-0 / / , the material color of the nylon bright yarn woven by JB2.1 and JB2.2 can be seen through the first weaving layer 100. Under the same conditions, when the light and shadow yarns are visible, the material color of the nylon bright yarn will be obscured and cannot be directly observed. Conversely, when the light and shadow yarns are not visible, the color of the nylon material is clearly visible, showing a uniform color distribution.

[0077] For the third braided layer 300: The third guide bar is knitted with GB2 warping 30D / 1F CD bright yarn (i.e., the fourth bright yarn), with a full needle bed count of 3072 stitches. It has 6 warp heads divided into 3 fabric widths (i.e., 1 fabric width with 2 warp heads and 1024 stitches), and 6 warp heads with 512 yarns. The GB2 yarn is threaded onto the machine in a full-thread manner, with a warp feed of 6300 mm / lap. The CD yarn content of GB2 is approximately 9.065%. For example, GB2 uses a variation weave 1-0 / 0-1 / 0-1 / 1-0 / / , connecting the first knitting layer 100 and the second knitting layer 200 to prevent delamination, creating a bouncy feel and good shock absorption.

[0078] Example 2 Corresponding to Embodiment 1 above, this application also provides a shoe upper, which is made of fabric.

Figures 5 to 7 It can be seen that the second bright yarn (such as bright polyester yarn) can reflect more light and form a bright highlight area under lighting conditions, while the third bright yarn (such as dull polyester or nylon) absorbs more light and presents a soft and non-glaring effect. When the two are interwoven, due to the difference in optical properties, they will produce a dynamic light and shadow effect on the same plane, and the fabric surface layer and the fabric bottom layer complement each other.
