Description

Technical Field

[0001] This application relates to the field of textile technology, specifically to a three-dimensional fabric. Background Technology

[0002] In today's ever-evolving textile industry, textured fabrics have become a highly sought-after category in the market due to their unique appearance and feel. They are widely used in various industries such as clothing and home textiles, giving products a distinctive charm.

[0003] The existing patent publication number CN107338568A, entitled "A Method for Manufacturing an Elastic Embossed Warp-Knitted Fabric and the Warp-Knitted Fabric," discloses that when knitting the raised areas of the embossed pattern, GB3 is formed in loops on the front needle mattress yarn of a double-needle bed warp knitting machine, and GB4 is formed in loops alternately on the front and rear needle mattress yarns of the double-needle bed warp knitting machine; when knitting the recessed areas of the embossed pattern, GB3 is formed in loops alternately on the front and rear needle mattress yarns of the double-needle bed warp knitting machine, and GB4 is formed in loops on the front needle mattress yarn of the double-needle bed warp knitting machine. Because GB4 uses low-elasticity or non-elastic yarn for threading, the yarn rebound after knitting is relatively small or non-existent. GB3 uses spandex core-spun yarn, which has a relatively greater yarn rebound after knitting. The yarn shrinks towards the bottom layer, causing the surface layer to sink downwards, forming an embossed structure with a certain degree of elasticity. However, when the warp-knitted fabric is stretched by external force, the uneven texture of the fabric surface will quickly become flat. Moreover, during long-term use or frequent stress, due to the continuous elastic shrinkage of GB3 spandex core-spun yarn and the tension imbalance of GB4 low-elasticity or non-elasticity yarn, the continuous elastic shrinkage of the former and the rigid restraint of the latter form an internal stress contradiction, which causes the uneven structure to gradually loosen and deform, thereby losing the three-dimensionality of the pattern and affecting its aesthetics and functionality. Utility Model Content

[0004] In view of the above problems, this application provides a three-dimensional fabric that solves the problem that the uneven texture of existing warp-knitted fabrics quickly becomes flat when subjected to tension.

[0005] To achieve the above objectives, the inventors provide a three-dimensional fabric comprising a surface layer, the surface layer comprising a first region and a second region, the first region being formed by stacking at least two-needle structures woven from a first yarn and a second yarn respectively; the at least two-needle structures are formed by the yarns alternately forming loops on at least two rows or columns of fabric; the thickness of the first region is greater than that of the second region.

[0006] In some embodiments, the at least two-needle tissue is at least two-needle plain weave or at least two-needle satin weave.

[0007] In some embodiments, the first region is formed by stacking at least two needle structures woven from a first yarn and a second yarn in the same or opposite directions.

[0008] In some embodiments, the first region is formed by at least two stitches woven from a first yarn and a second yarn, with the same or different stitch counts.

[0009] In some embodiments, the second region is formed by stacking at least two-needle structures woven from the first yarn and the second yarn respectively; the total number of stitches in the at least two-needle structures in the first region is greater than the total number of stitches in the at least two-needle structures in the second region, so that the thickness of the first region is greater than that of the second region.

[0010] In some embodiments, the second region is formed by weaving at least the first yarn and the second yarn into a plain weave, a satin weave, a chain weave, or a quilted weave.

[0011] In some embodiments, a bottom layer is also included, the bottom layer being woven from at least a third yarn, wherein the first yarn, the second yarn, and / or the third yarn are woven together in loops to connect the top layer and the bottom layer.

[0012] In some embodiments, the system further includes a bottom layer and an intermediate layer located between the top layer and the bottom layer, wherein the bottom layer is woven from at least a third yarn and the intermediate layer is formed by connecting the top layer and the bottom layer from at least a fourth yarn.

[0013] In some embodiments, in the second region, the second yarn is woven in the surface layer and the bottom layer to make the surface layer of the second region recessed towards the bottom layer.

[0014] In some embodiments, the surface layer further includes a fifth yarn, which is woven together with the first yarn and the second yarn to form a mesh structure in the surface layer.

[0015] Unlike existing technologies, the above-mentioned three-dimensional fabric solution proposes setting different areas on the surface layer, with different thicknesses in each area to create a textured surface. When the three-dimensional fabric is stretched by external force, the raised, thick areas effectively resist deformation and maintain their three-dimensional shape due to the high interlacing density and rigid structure formed by the stacked weave. Although other areas in the recessed areas experience some stretching, the stretching range is strictly limited due to the restraining effect of the thick weave, so that the thick areas still maintain the thickness difference with other areas, preserving the textured surface and ensuring that the textured surface is always clearly visible, thus achieving long-term stability of the three-dimensional effect.

[0045] In the current textile market, traditional textured fabrics are mostly three-layered, relying on the difference in shrinkage rates between the top layer (10%) and the bottom layer (30%) yarns to create the texture. While this process can produce a three-dimensional effect, the uneven elasticity of the yarns exacerbates the tension imbalance between the top and bottom yarns when the fabric is stretched. This causes the raised areas to be forcibly flattened, and the recessed areas to extend, resulting in the rapid disappearance of the texture. This severely affects the aesthetics and functionality of the product, greatly limiting its application in scenarios such as dynamic clothing wear and frequent home use.

[0046] To this end, the three-dimensional fabric of this application proposes to set different regions on the surface layer 10, with different thicknesses in each region to create a textured surface. The thicker regions are mainly achieved by using multiple yarns to form loops in at least two rows or columns, allowing the different yarns to stack in these regions, creating a thickness difference with other regions. When the three-dimensional fabric is stretched by external force, the raised, thicker regions effectively resist deformation and maintain their three-dimensional shape due to the high interlacing density and rigid structure formed by the stacked structures. While other areas in the recessed regions experience some stretching, the stretching is strictly limited by the restraining effect of the thicker structures, ensuring that the thicker regions still maintain a thickness difference with other regions, preserving the textured surface, and ensuring the texture remains clearly visible, thus achieving long-term stability of the three-dimensional effect.

[0047] The three-dimensional fabric of this application can be applied in the fields of clothing, home furnishings, and footwear materials, and is especially suitable for shoe uppers. The stable three-dimensional structure after stretching prevents the shoe upper from deforming during wear. Even after prolonged walking, strenuous exercise, or repeated bending, the textured surface maintains its original shape, effectively preventing wrinkling and sagging. Simultaneously, the textured structure increases the friction between the shoe upper and the foot, improving fit and comfort. Furthermore, the special textured arrangement enhances breathability and support, providing consumers with a wearing experience that combines aesthetics and practicality, meeting the needs of various scenarios such as fashion and sports.

[0048] See Figure 1 As shown, the following is an embodiment of a three-dimensional fabric, which includes a surface layer 10. The surface layer 10 includes a first region 101 and a second region 102. The first region 101 is formed by stacking at least two-needle structures woven from a first yarn and a second yarn, respectively. The at least two-needle structure is formed by the yarns being looped alternately on at least two rows or columns of fabric. The thickness of the first region 101 is greater than that of the second region 102.

[0049] The first region 101 and the second region 102 mentioned above represent two regions with different thicknesses set on the surface layer 10 to form a textured surface layer 10. It is worth emphasizing that in practical applications, a third region, a fourth region, etc., can be added as needed to create more complex relief effects, functional partitions, or dynamic response structures through multi-level thickness gradients, meeting the needs of diverse scenarios from fashion design to medical rehabilitation.

[0050] Here, the shapes of the first region 101 and the second region 102 are not limited and can be set according to actual needs. Whether it is a regular geometric shape, such as a square, circle, or triangle, or an irregular natural form, such as leaf veins, cloud patterns, or abstract artistic patterns, all can be realized through processing. There can be multiple first regions 101 and second regions 102 in this application. The shapes of the multiple first regions 101 can be different or the same; similarly, the shapes of the multiple second regions 102 can be different or the same. On the surface layer 10, different shapes of the first regions 101 and second regions 102 can be freely combined according to the functional requirements and aesthetic style of the product. For example, in the shoe upper, the first region 101 can be designed as a streamlined shape that conforms to the arch curve of the foot, providing targeted support, while the second regions 102 are distributed on both sides of the shoe upper with hollowed-out polygons to enhance breathability.

[0051] The aforementioned first region 101 is formed by stacking at least two-needle structures woven from at least the first yarn and the second yarn, respectively. This refers to the layering of at least two-needle structures woven from at least the first yarn and the second yarn in the height direction. The aforementioned at least two-needle structure refers to the yarn forming loops alternately on at least two rows or columns of fabric. This means that during the knitting process, the yarn is not limited to forming loops on a single row or column, but rather alternates between at least two rows or columns of fabric according to a preset weave cycle. Taking a warp knitting machine as an example, when knitting a two-needle structure, the yarn will follow a preset weave cycle, such as first forming a loop on the first needle, then crossing over to the second adjacent needle, forming an extension line in the transverse direction (weave direction) to connect different loops; when knitting a three-needle structure, the yarn will follow a preset weave cycle, such as first forming a loop on the first needle, then crossing over to the second and third adjacent needles, forming an extension line in the transverse direction (weave direction) to connect different loops. Specifically, it can be at least two-needle plain weave or at least two-needle satin weave; and so on. The at least two-needle plain weave involves each yarn looping alternately on at least two adjacent needles in a certain horizontal row. Taking a two-needle plain weave as an example, a yarn loops on needle A in one horizontal row, then loops on the adjacent needle B in the next horizontal row, and then returns to needle A in the next horizontal row, and so on. The at least two-needle satin weave involves each yarn looping sequentially on two or more needles in a certain horizontal row, and then sequentially returning, typically forming a symmetrical zigzag or herringbone pattern.

[0052] The aforementioned first region 101 is formed by stacking at least two-needle structures knitted by at least the first yarn and the second yarn, respectively. This stacking can be either unidirectional or counter-directional; that is, the first region 101 is formed by stacking at least two-needle structures knitted by at least the first yarn and the second yarn, respectively, in the same direction and / or in the opposite direction. The aforementioned unidirectional stacking of at least two-needle structures knitted by at least the first yarn and the second yarn refers to the multiple yarns not intersecting during the alternating transfer between multiple rows or columns of fabric. For example, if the first yarn and the second yarn are each knitted as a three-needle warp plain weave, stacked in the same direction (see [link to relevant documentation]). Figure 2 As shown), for example, the first yarn and the second yarn are respectively knitted in a three-needle plain weave and a two-needle plain weave, stacked in the same direction (see...). Figure 4 (As shown). The aforementioned at least two-needle structure knitted by at least the first yarn and the second yarn respectively, stacked in reverse, refers to the intersection of multiple yarns during the alternating transfer between multiple rows or columns of fabric, forming regular or irregular polygonal shapes (such as diamond patterns) between adjacent rows or columns. For example, the first yarn and the second yarn respectively knit three-needle warp plain weave stacked in reverse (see...). Figure 3 As shown), for example, the first yarn and the second yarn are respectively knitted in a three-needle plain weave and a two-needle plain weave, stacked in opposite directions (see...). Figure 5 (As shown).

[0053] The aforementioned stacked at least two-needle structures can be the same or different at least two-needle structures. In some embodiments, the first yarn is woven into at least two-needle warp plain weave, the second yarn is woven into at least two-needle warp satin weave, and the at least two-needle warp plain weave and at least two-needle warp satin weave are stacked to form the first region 101; in some embodiments, the first yarn is woven into at least two-needle warp plain weave, the second yarn is woven into at least two-needle warp plain weave, and the two at least two-needle warp plain weaves are stacked to form the first region 101. It should be noted that regardless of whether the at least two-needle structures are the same or not, the number of stitches (the number of alternating rows or columns of fabric) in the at least two-needle structures can be the same or different. That is, the first region 101 is formed by at least two-needle structures woven by the first yarn and the second yarn respectively, with the same or different number of stitches. For example, the first region 101 is formed by stacking at least three-needle warp plain weaves woven by the first yarn and the second yarn respectively (see...). Figures 2-3 (as shown); for example, the first region 101 is formed by stacking at least three-needle plain weave and two-needle plain weave fabrics woven from the first yarn and the second yarn respectively (see...). Figures 4-5 (As shown).

[0054] The thickness of the second region 102 is less than that of the first region 101. When the two regions are distributed alternately on the surface layer 10 of the three-dimensional fabric, the thicker region naturally protrudes to form a three-dimensional outline, while the thinner region is relatively concave. The thickness difference between the two creates a textured surface layer 10 of the three-dimensional fabric.

[0055] In some embodiments, the second region 102 is formed by at least the first and second yarns woven into a plain warp weave, a satin warp weave, a chain weave, or a padded weave. The aforementioned plain warp weave, chain weave, or padded weave does not create a stacking effect in the second region 102. The chain weave involves each yarn always looping on the same needle, forming a single isolated loop in a longitudinal row. The padded weave involves some yarns not being padded or looped in certain weave rows (i.e., "padded"), while looping normally in other weave rows.

[0056] In some embodiments, the second region 102 is identical to the first region 101, but may also be formed by stacking different weaves. For example, it may be formed by stacking at least two of the following weaves: plain weave, satin weave, chain weave, or sparse weave. See also Figure 6-7 As shown, in some embodiments, the second region 102 is formed by stacking at least two-needle warp knit (red) and padding (black) structures woven from the first and second yarns, respectively; see also Figure 8 As shown, in some embodiments, the second region 102 is formed by stacking at least two-needle plain weave (red) and chain weave (black) knitted from the first yarn and the second yarn, respectively; see also Figure 9 As shown, in some embodiments, the second region 102 is formed by stacking at least a padding structure (red) and a chain structure (black) woven from the first yarn and the second yarn, respectively. In some embodiments, the second region 102 is formed by stacking at least a two-needle structure woven from the first yarn and the second yarn, respectively; in this case, it should be noted that the total number of stitches in the at least two-needle structure in the first region 101 is greater than the total number of stitches in the at least two-needle structure in the second region 102, so that the thickness of the first region 101 is greater than that of the second region 102. For example, the first region 101 is formed by stacking at least a three-needle structure woven from the first yarn and the second yarn, respectively, and the second region 102 is formed by stacking at least a two-needle structure woven from the first yarn and the second yarn, respectively. For example, the first region 101 is formed by stacking at least four-needle structures woven from the first yarn and the second yarn respectively, and the second region 102 is formed by stacking at least three-needle structures woven from the first yarn and the second yarn respectively; or the first region 101 is formed by stacking at least three-needle structures woven from the first yarn and two-needle structures woven from the second yarn, and the second region 102 is formed by stacking at least two-needle structures woven from the first yarn and the second yarn respectively.

[0057] The aforementioned first and second yarns represent at least two-needle weaves stacked to form the first region 101. The characteristics and quantity of the first and second yarns are not limited. If multiple yarns are present, they can have different or the same characteristics, which can be selected according to requirements. Fabric design diversity can be achieved by changing the color of the yarns. Similarly, the first and second yarns can have different or the same characteristics, and their quantities can be the same or different. The aforementioned characteristics refer to yarn color, material, elasticity, etc.

[0058] The surface layer 10 may also include other yarns, which, in combination with the first and second yarns, form different textures. In some embodiments not shown, the surface layer 10 may further include a fifth yarn, which is woven with the first and second yarns to form a mesh structure in the surface layer 10. The mesh structure may be located in the first region 101 and / or the second region 102. In some embodiments not shown, the surface layer 10 may further include a sixth yarn, which is woven with the first and second yarns to form a colored jacquard layer in the surface layer 10. Through the interweaving and structural variations of multicolored yarns, a composite effect combining visual depth and three-dimensional texture is created.

[0059] See Figure 10 As shown, in some embodiments, the three-dimensional fabric of this application can be a double-layer structure, that is, it also includes a bottom layer 30, which is woven into shape by at least a third yarn and then composited with the surface layer 10; the bottom layer 30 can also be woven into shape together with the surface layer 10, that is, the bottom layer 30 is woven into shape by at least a third yarn, and the first yarn, the second yarn and / or the third yarn are hooked into loops to connect the surface layer 10 and the bottom layer 30.

[0060] See Figure 11 As shown, in some embodiments, the three-dimensional fabric of this application may be a three-layer structure, further including a bottom layer 30 and an intermediate layer 20 located between the top layer 10 and the bottom layer 30. The bottom layer 30 is woven from at least a third yarn, and the intermediate layer 20 is formed by connecting the top layer 10 and the bottom layer 30 with at least a fourth yarn. See also Figure 12 As shown, specifically, to make the textured surface more pronounced, a second yarn can be woven between the surface layer 10 and the bottom layer 30 in the second region 102. The second yarn is an elastic yarn, causing the surface layer 10 of the second region 102 to concave towards the bottom layer 30. The second yarn is an elastic yarn. The first yarn uses low-elasticity or non-elasticity yarn for weaving. After weaving, the first yarn has relatively little or no rebound, while the second yarn has a relatively greater rebound. The yarn will contract towards the bottom layer 30, causing the surface layer 10 to concave downwards towards the bottom layer 30, forming the textured surface.

[0061] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
