Description

Technical Field

[0001] The present invention provides a weaving structure, and more particularly a biomimetic fabric. Background Technology

[0002] With the improvement of living standards, the advancement of technology, and the change in consumption concepts, people have increasingly higher requirements for clothing, food, housing, and transportation. Furthermore, with the continuous emergence of various functional textiles, the development of functional textiles with specific purposes is becoming increasingly sophisticated, thus functional fabrics are attracting more and more attention.

[0003] Comfort is a key factor for consumers when choosing clothing. For wearable fabrics, sweat and increased ambient humidity often cause them to stick to the wearer's skin, significantly reducing comfort. During strenuous physical activity or manual labor, users produce a lot of sweat. If this sweat cannot be quickly wicked away from clothing or protective gear, the skin will feel hot and uncomfortable. Furthermore, users consider the stretchability of sportswear when choosing equipment. Poor stretchability of the fabric results in poor movement tracking and an inability to integrate with muscle movements, hindering athletic performance and failing to support the user's physical activity.

[0004] Therefore, improving the breathability and stretchability of wearable fabrics to enhance user comfort and provide support for user movement is an important research topic for the textile industry. Utility Model Content

[0005] The purpose of this invention is to provide a biomimetic fabric that, by setting an elastic bottom layer and a surface layer with multiple openings, can have both excellent extensibility and breathability. When applied to sports equipment, it can extend and expand with the user's exercise intensity and movements, and can allow the heat and sweat expelled from the user's skin to be quickly expelled from the biomimetic fabric, so that the user feels dry during exercise.

At the warp connecting edge, the first warp yarns are woven into the base layer. At the warp opening edge, the surface layer is not connected to the base layer, and the warp opening edge includes a second warp yarn, which is a polyester monofilament yarn. The weft connecting portions are spaced apart from each other, and at each weft connecting portion, a weft yarn is woven into the base layer to form multiple open structures. The sealing layer is disposed at the outer edge of the base layer and the outer edge of the surface layer.

[0034] The embodiments of the present invention will be described below with reference to the accompanying drawings. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit the scope of the present invention. That is, in some embodiments of the present invention, these practical details are not essential. Furthermore, for the sake of simplicity in the drawings, some known and conventional structures and components will be shown in a simple schematic manner; and repeated components may be denoted by the same number.

[0035] Please refer to Figures 1 to 5 , Figure 1A three-dimensional schematic diagram of a biomimetic fabric 100 according to an embodiment of the present invention is shown. Figure 2 It is a drawing according to Figure 1 A schematic diagram of the front warp stretching of the biomimetic fabric 100 in this embodiment. Figure 3 It is a drawing according to Figure 1 A schematic diagram of the front weft stretching of the biomimetic fabric 100 in this embodiment. Figure 4 It is a drawing according to Figure 1 A schematic diagram of the back side of the biomimetic fabric 100 in the embodiment. Figure 5 It is a drawing according to Figure 1 A schematic diagram of the back weft stretch of the biomimetic fabric 100 in this embodiment. The biomimetic fabric 100 includes a bottom layer 200, a top layer 300, and a sealing layer 400.

[0036] The bottom layer 200 is woven from multiple elastic yarns (not shown), each of which can be a covered elastic yarn. The denier of the covered elastic yarn can be 70D to 140D, and the strand count can be 75F to 300F. Further, the covered elastic yarn can be a core-spun yarn, an air-covered yarn, a single-wound elastic yarn, a double-wound elastic yarn, or a combination thereof. Specifically, to achieve four-way elastic extension tension that meets the requirements of movement and the three-dimensional structure, both the warp and weft directions of the bottom layer 200 can use single-wound elastic yarns with a denier of 70D to 140D and a strand count of 75F to 300F, i.e., 75D to 300D polyester multifilament yarn covering 70D to 140D elastic multifilament yarn. Preferably, it can be a 70D / 75F single-wound elastic yarn, a 70D / 150F single-wound elastic yarn, or a 140D / 300F single-wound elastic yarn. It is produced on a knitting machine with 22 to 18 needles. Preferably, the bottom layer 200 is produced on a knitting machine with 18 needles and a wider needle spacing, which can improve the flatness of the bottom layer 200.

[0037] Furthermore, the bottom layer 200 may have multiple mesh openings 210. Specifically, the elastic yarns in the warp and weft directions can be woven into a mesh structure to form the mesh openings 210. In this way, the mesh openings 210 can increase the breathability of the bottom layer 200. In addition, the mesh openings 210 can increase the physical stretch and elastic deformation capacity of the bottom layer 200, so that the bionic fabric 100 can have higher fit and movement extension, thereby increasing the comfort when wearing the bionic fabric 100.

[0038] The surface layer 300 is woven from multiple first warp yarns (not shown) and multiple weft yarns (not shown), and is partially connected to the bottom layer 200. The surface layer 300 includes multiple open structure rows 310, which are arranged parallel to each other. Each open structure row 310 includes a warp connecting edge 320, a warp opening edge 330, and multiple weft connecting portions 340. At the warp connecting edge 320, the first warp yarns are woven into the bottom layer 200, thus partially connecting the surface layer 300 to the bottom layer 200. At the warp opening edge 330, the surface layer 300 is not connected to the bottom layer 200, and the warp opening edge 330 includes second warp yarns 331, which are polyester monofilament yarns. The weft connecting portions 340 are spaced apart from each other; preferably, the weft connecting portions 340 are equidistant from each other. Furthermore, at each weft connection 340, the weft yarn is woven into the bottom layer 200, so that the top layer 300 is partially connected to the bottom layer 200 to form multiple open structures 350.

[0039] In detail, the first warp and weft yarns of the outer layer 300 are non-elastic and can be cotton yarn, linen yarn, silk yarn, polyester multifilament yarn, nylon yarn, polypropylene fiber yarn, or a combination thereof. Preferably, the first warp yarn is polyester multifilament yarn with a denier of 75D to 300D, and the weft yarn is polyester multifilament yarn with a denier of 75D to 300D. The outer layer 300 woven from the first warp and weft yarns can be a knitted fabric. This ensures the structural strength of the biomimetic fabric 100 for application in products requiring high strength.

[0040] The biomimetic fabric 100 is constructed with an elastic yarn weave in the bottom layer 200 and a non-elastic yarn weave in the top layer 300. The elastic band of the top layer 300, which does not shrink, creates a shrinkage effect after the bottom layer 200 shrinks, giving the biomimetic fabric 100 a three-dimensional structure. Each open structure row 310 of the top layer 300 is connected to the bottom layer 200 using different connection methods: a single-sided warp connection and a double-sided weft connection. Specifically, the warp connection edge 320 and the weft connection part 340 are connected to the bottom layer 200, while the warp open edge 330 is not connected. This allows the asymmetrical tension generated in the biomimetic fabric 100 to create gill-like open structures 350, serving as airflow channels. This allows heat generated by the user's skin to escape through the open structures 350, or allows external air to flow in, reducing the user's feeling of stuffiness. Furthermore, the surface layer 300 with an open structure 350, combined with the bottom layer 200 with a mesh 210, can dynamically adjust the breathability of the biomimetic fabric 100.

[0041] Furthermore, the second warp yarn 331 is a polyester monofilament yarn with a diameter ranging from 0.07 mm to 0.25 mm. By interlacing the second warp yarn 331 with the warp opening edge 330 of each opening structure row 310, it serves as a support structure for stabilizing the opening structure 350, making the opening end of the opening structure 350 semi-circular arched, and giving the surface layer 300 multiple opening structures 350 resembling tent edges. Each opening structure 350 has a warp length and a weft width. In the unstretched state, the warp length can be 0.7 mm to 0.8 mm, and the weft width can be 0.5 mm to 0.7 mm. For example, in one embodiment, the warp length of the opening structure 350 is 0.7 mm and the weft width is 0.5 mm; in another embodiment, the warp length of the opening structure 350 is 0.8 mm and the weft width is 0.7 mm. However, the present invention is not limited to these. The spacing between the two weft connecting parts 340 (i.e., the warp length of the opening structure 350) and the width of each row of opening structures 310 (i.e., the weft width of the opening structure 350) can be adjusted as needed.

[0042] The edge sealing layer 400 is disposed on the outer edge of the bottom layer 200 and the outer edge of the top layer 300, so that the bottom layer 200 and the top layer 300 are sewn together by the edge sealing layer 400 to obtain a biomimetic fabric 100 with a three-dimensional elastic band structure.

[0043] The biomimetic fabric 100 has a warp elongation and a weft elongation, with the warp elongation ranging from 150% to 350% and the weft elongation ranging from 110% to 200%. In other words, the biomimetic fabric 100 has... Figure 2 Under warp tension, the warp length can be Figure 1 The unstretched state is 1.5 to 3.5 times that of the biomimetic fabric 100. Figure 3 and Figure 5 Under latitudinal stretching, the latitudinal width can be Figure 1 The stretchability is 1.1 to 2 times that of the unstretched state. Specifically, when the bottom layer 200 is woven with single-wrap elastic yarn of 70D / 75F denier and 75F yarns respectively, the warp stretchability of the biomimetic fabric 100 can reach 150% and the weft stretchability can reach 110%. When the bottom layer 200 is woven with single-wrap elastic yarn of 140D / 300F denier and 350F yarns respectively, the warp stretchability of the biomimetic fabric 100 can reach 350% and the weft stretchability can reach 200%. Therefore, the biomimetic fabric 100 has excellent extensibility, giving it good motion tracking capabilities, allowing it to integrate with the user's muscle movements. Furthermore, its four-way stretching characteristics enhance the coverage of the biomimetic fabric 100 for the user.

[0044] Furthermore, the color of the bottom layer 200 can differ from the color of the top layer 300. This allows the biomimetic fabric 100 to achieve a two-tone effect by utilizing the different colors of the bottom layer 200 and the top layer 300. When unstretched, it can exhibit an opening structure 350 resembling fish gills, and when stretched in the weft direction, it can present a mesh structure 210 like venetian blinds. Additionally, the warp and weft elastic yarns of the bottom layer 200 can be different colors, or the first warp and weft yarns of the top layer 300 can also be different colors, allowing the bottom layer 200 and / or the top layer 300 to form diverse and rich variations, such as different grid patterns. However, the scope of this invention is not limited to these limitations.

[0045] Please refer to Table 1 below for the yarn distribution method and test results of warp and weft elongation of the biomimetic fabric of this utility model.

[0049] In summary, the biomimetic fabric of this invention, by incorporating an elastic bottom layer and a surface layer with multiple openings, achieves both excellent stretchability and breathability. When applied to wearable sports equipment, it expands and extends with the user's exercise intensity and movements, allowing heat and sweat from the user's skin to be quickly released, keeping the user feeling dry during exercise. Furthermore, if the surface layer with openings is combined with a mesh bottom layer, the breathability of the biomimetic fabric can be dynamically adjusted as if it were alive. The bottom layer, with its four-way extension, enhances the biomimetic fabric's coverage of the user, giving it excellent motion tracking. Therefore, it is suitable for use in the manufacture of wearable sports equipment, such as in the garment industry for sports jackets, close-fitting sportswear, and functional stripes on trousers; as uppers for running shoes, basketball shoes, etc.; and in sports accessories for wearable sports equipment. Furthermore, the surface of the biomimetic fabric of this invention has multiple opening structures, and its appearance is like fish gills, which allows the biomimetic fabric of this invention to have diverse and rich fabric variations.
