Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabrics, and more specifically, to an elastic fabric. Background Technology
[0002] Common elastic fabrics often achieve their elasticity by incorporating elastic fibers such as spandex into the weft direction on a plain weave basis. However, when the elasticity of the fabric mainly depends on the elastic fibers themselves, when the fabric is repeatedly stretched, the stress of the elastic fibers in the plain weave structure tends to concentrate on a certain part of the yarn. This makes the elastic fibers prone to elastic deformation and fatigue after repeated stretching, which in turn leads to the breakage of the elastic fibers, resulting in problems such as fabric loosening, arching, and poor shape retention. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an elastic fabric in which the first and second horizontal stripe areas are wavy and fitted together along the length of the fabric, and the first and second regions are wavy and fitted together along the length of the fabric. When the fabric is stretched along its width, the wavy fitting points will unfold as the tension increases, thereby buffering the elastic fibers in the weft direction, reducing the direct stress on the elastic fibers, and extending the service life of the fabric. At the same time, the wavy structure reduces the content of elastic fibers, reducing costs while still achieving the same elastic effect. Furthermore, the second unit is higher than the first unit, and the first region is higher than the second region. As the tension increases, the unit structures of different heights are gradually flattened, so that the stress is evenly and gradually distributed throughout the fabric, rather than concentrated on a certain part of the yarn. After the external force is removed, the fabric allows the fibers to recover quickly through the wavy structure and the unit structures of different heights, thereby reducing the risk of deformation and increasing the fatigue resistance and shape retention of the fabric.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: an elastic fabric, comprising a first horizontal stripe area and a second horizontal stripe area arranged alternately and cyclically along the fabric length direction, the first horizontal stripe area and the second horizontal stripe area being wavy and fitted together, the first horizontal stripe area comprising a first unit and a second unit, the first unit and the second unit being alternately arranged along the fabric width direction, in two adjacent first horizontal stripe areas, along the fabric length direction, the first unit in one first horizontal stripe area is opposite to the second unit in another first horizontal stripe area, and the second unit in one first horizontal stripe area is opposite to the first unit in another first horizontal stripe area, the second horizontal stripe area comprising two first regions and a second region located between the two first regions, the first region and the second region being wavy and fitted together along the fabric length direction.
[0005] The present invention is further configured such that the arc lines at both ends of the first unit are convex along the length of the fabric, and the arc lines at both ends of the second unit are concave along the length of the fabric.
[0006] The present invention is further configured such that the width H1 of the first unit along the fabric width direction is the same as the width H2 of the second unit along the fabric width direction.
[0007] The present invention is further configured such that the second unit is higher than the first unit.
[0008] The present invention is further configured such that the first region is higher than the second region.
[0009] The present invention is further configured such that the fabric is woven with 90 warp yarns and 122 weft yarns to form a weave cycle, 90 warp yarns and 63 weft yarns to form the first horizontal stripe area, and 90 warp yarns and 9 weft yarns to form the second horizontal stripe area.
[0010] The present invention is further configured such that 45 warp yarns and 63 weft yarns are interwoven to form the first unit, and 45 warp yarns and 51 weft yarns are interwoven to form the second unit.
[0011] The present invention is further configured such that, along the length direction of the fabric, the length of the first unit is longer than the length of the second unit, and the length of the first region is longer than the length of the second region.
[0012] In summary, this utility model has the following beneficial effects:
[0013] The first and second horizontal stripe areas are wavy together along the fabric length, as are the first and second regions. When the fabric is stretched along its width, the wavy fit is woven with the tension, reducing the direct stress on the elastic fibers and buffering the weft elastic fibers, thus extending the fabric's lifespan. Simultaneously, the second unit is higher than the first unit, and the first region is higher than the second region. Therefore, as the tension increases, the first and second units are gradually flattened along the width, and the first and second regions are gradually flattened along the length. This allows stress to be evenly and gradually distributed across the entire fabric, rather than concentrated on a particular section of yarn. After the external force is removed, the fabric's wavy structure and the varying heights of the unit structures allow the fibers to quickly recover, thus reducing fabric deformation.

Warp yarns 1-14, 32-56, and 80-90 interweave; weft yarn 2 interweaves with warp yarns 1-11, 35-59, and 77-90; weft yarn 3 interweaves with warp yarns 1-8 and 38-90; weft yarn 4 interweaves with warp yarns 1-5 and 41-90; weft yarn 5 interweaves with warp yarns 1-2 and 44-90; weft yarn 6 interweaves with warp yarns 46-90; weft yarn 7 interweaves with warp yarns 48-88; weft yarn 8 interweaves with warp yarns 51-85; weft yarn 9 interweaves with warp yarns 54-82; weft yarn 10 interweaves with warp yarns 57-79; weft yarn 11 interweaves with warp yarns 60-76; weft yarn 114 interweaves with warp yarns 15-31; weft yarn 11... The 5th weft yarn interweaves with the 12th-34th warp yarns; the 116th weft yarn interweaves with the 9th-37th warp yarns; the 117th weft yarn interweaves with the 6th-40th warp yarns; the 118th weft yarn interweaves with the 3rd-43rd warp yarns; the 119th weft yarn interweaves with the 1st-45th warp yarns; the 120th weft yarn interweaves with the 1st-47th and 89th-90th warp yarns; the 121st weft yarn interweaves with the 1st-50th and 86th-90th warp yarns; and the 122nd weft yarn interweaves with the 1st-53rd and 83rd-90th warp yarns to form the second horizontal stripe area 2. Because the weft yarns of the first horizontal stripe area 1 and the second horizontal stripe area 2 interweave alternately, the fabric includes the first horizontal stripe area 1 and the second horizontal stripe area 2 arranged alternately along the length direction, and 90 warp yarns interweave with 66 weft yarns to form the first horizontal stripe area. Section 1 consists of 90 warp yarns interlacing with 9 weft yarns to form the second horizontal section 2. Because the number of weft yarns in the first horizontal section 1 gradually increases from the 1st to the 15th warp yarn, while the weft yarn interlacing position in the second horizontal section 2 gradually increases, from the 15th to the 31st warp yarn, the number of weft yarns in the first horizontal section 1 remains unchanged, while the weft yarn interlacing position in the second horizontal section 2 remains unchanged. From the 31st to the 60th warp yarn, the number of weft yarns in the first horizontal section 1 gradually decreases, while the weft yarn interlacing position in the second horizontal section 2 gradually decreases. From the 60th to the 76th warp yarn, the number of weft yarns in the first horizontal section 1 remains unchanged, while the weft yarn interlacing position in the second horizontal section 2 remains unchanged. From the 76th to the 90th warp yarn…The number of weft yarns in the first horizontal stripe area 1 gradually increases, while the weft yarn interlacing position in the second horizontal stripe area 2 gradually increases. Therefore, the first horizontal stripe area 1 and the second horizontal stripe area 2 form a wavy fit. The weft yarns are made of 40-count rayon fiber and 40D spandex fiber interlaced in a 1:1 ratio. Therefore, when the fabric is stretched along its direction, the wavy fit straightens with the tension, reducing the direct stress on the spandex fibers through the wavy structure. This cushions the weft spandex fibers, extending the fabric's lifespan. Simultaneously, because of the wavy structure combined with the 1:1 weft yarn arrangement, the spandex fiber content is reduced through structural design, thus lowering costs while maintaining the same elasticity.
[0022] When the first horizontal stripe area 1 is located within the interlacing range of warp yarns 1-90 and weft yarns 1-63, warp yarns 1-2 and 44-45 interlac with weft yarns 6-58, warp yarns 3-5 and 41-43 interlac with weft yarns 5-59, warp yarns 6-8 and 38-40 interlac with weft yarns 4-60, warp yarns 9-11 and 35-37 interlac with weft yarns 3-61, warp yarns 12-14 and 32-34 interlac with weft yarns 2-62, warp yarns 15-31 interlac with weft yarns 1-63 to form the first unit 11, warp yarns 46-47 and 89-90 interlac with weft yarns 7-57, warp yarns 48-50 and 86-88 interlac with weft yarns 8-56, and warp yarns 51- Warp yarns 53, 83-85, and 9-55 interweave; warp yarns 54-56, 80-82, and 10-54 interweave; warp yarns 57-59, 77-79, and 11-53 interweave; warp yarns 60-76 and 12-52 interweave to form the second unit 12. When the first horizontal stripe area 1 is located between warp yarns 1-90 and the second weft yarn in the next cycle (62-118), warp yarns 1-2, 44-45, and 68-118 interweave; warp yarns 3-5, 41-43, and 69-117 interweave; warp yarns 6-8, 38-40, and 70-116 interweave; warp yarns 9-11, 35-37, and 71-11... The first unit (unit 12) is formed by interlacing 5 weft yarns, warp yarns 12-14 and 32-34 interlacing with weft yarns 72-114, warp yarns 15-31 interlacing with weft yarns 73-113, warp yarns 46-47 and 89-90 interlacing with weft yarns 67-119, warp yarns 48-50 and 86-88 interlacing with weft yarns 66-120, warp yarns 51-53 and 83-85 interlacing with weft yarns 65-121, warp yarns 54-56 and 80-82 interlacing with weft yarns 64-122, warp yarns 57-59 and 77-79 interlacing with weft yarn 1 and weft yarns 63-122, and warp yarns 60-76 interlacing with weft yarns 1-2 and weft yarns 62-122. Unit 11, because the first unit 11 and the second unit 12 are interwoven through alternating warp yarns, the first horizontal stripe area 1 includes the first unit 11 and the second unit 12, which are arranged alternately along the fabric width. The first unit 11 is formed by the interweaving of 45 warp yarns and 63 weft yarns, and the second unit 12 is formed by the interweaving of 45 warp yarns and 51 weft yarns. When the first horizontal stripe area 1 is located within the interweaving range of the 1st to 90th warp yarns and the 1st to 63rd weft yarns, the first unit 11 is located at the interweaving point of the 1st to 45th warp yarns and the 1st to 63rd weft yarns. When the first horizontal stripe area 1 is located within the interweaving range of the 1st to 90th warp yarns and the 62nd to the 2nd weft yarn in the next cycle, the 1st to 45th warp yarns and the 68th to 118th weft yarns interweave to form the second unit 12.When the first horizontal stripe area 1 is located within the interlacing range of warp yarns 1-90 and weft yarns 1-63, the second unit is located at the interlacing point of warp yarns 46-90 and weft yarns 7-57. When the first horizontal stripe area 1 is located between warp yarns 1-90 and the second weft yarn in the next cycle 62, the warp yarns 46-90 and the second weft yarn in the next cycle 62 interlac to form the first unit 11. Therefore, in two adjacent first horizontal stripe areas 1, along the fabric length direction, the first unit 11 in one first horizontal stripe area 1 is opposite to the second unit 12 in the other first horizontal stripe area 1, and the second unit 12 in one first horizontal stripe area 1 is opposite to the first unit 11 in the other first horizontal stripe area 1. Furthermore, the arc lines at both ends of the first unit 11 are convex along the fabric length direction, and the arc lines at both ends of the second unit 12 are concave along the fabric length direction. This allows the first unit 11 and the second unit 12 to form unit structures with different arc-shaped end faces, and the first unit 11 and the second unit 12 are arranged alternately. Therefore, when the fabric is subjected to stress, the stress can be evenly and gradually distributed throughout the entire fabric, thus avoiding stress concentration and reducing the risk of breakage of the weft spandex fibers due to excessive local stress.
[0023] Within the interlacing range of the warp and weft yarns in the second horizontal stripe area 2, the 53rd weft yarn interlaced with the 60th-76th warp yarns, the 54th weft yarn interlaced with the 57th-79th warp yarns, the 55th weft yarn interlaced with the 54th-82nd warp yarns, the 56th weft yarn interlaced with the 51st-61st and 77th-85th warp yarns, the 57th weft yarn interlaced with the 48th-57th and 79th-88th warp yarns, the 58th weft yarn interlaced with the 46th-54th and 79th-90th warp yarns, the 59th weft yarn interlaced with the 1st-2nd warp yarns, the 44th-51st warp yarns, the 62nd-74th warp yarns, and the 85th-90th warp yarns, and the 60th weft yarn interlaced with the 1st-5th warp yarns, the 41st-48th warp yarns, the 58th-78th warp yarns, and the 88th-90th warp yarns. The 61st weft yarn interweaves with warp yarns 1-8, 38-45, and 55-81; the 62nd weft yarn interweaves with warp yarns 4-11, 35-42, 52-59, and 77-84; the 63rd weft yarn interweaves with warp yarns 7-14, 32-39, 49-56, and 80-87; the 64th weft yarn interweaves with warp yarns 10-36, 46-53, and 83-90; the 65th weft yarn interweaves with warp yarns 1-3, 13-33, 43-50, and 86-90; and the 66th weft yarn interweaves with warp yarns 1-6, 17-29, 40-47, and 89-90. The yarns interweave as follows: the 67th weft yarn interweaves with warp yarns 1-9 and 37-45; the 68th weft yarn interweaves with warp yarns 3-12 and 34-43; the 69th weft yarn interweaves with warp yarns 6-16 and 30-40; the 70th weft yarn interweaves with warp yarns 9-37; the 71st weft yarn interweaves with warp yarns 12-34; the 72nd weft yarn interweaves with warp yarns 15-31 to form the first region 21; the 56th weft yarn interweaves with warp yarns 62-84; the 57th weft yarn interweaves with warp yarns 58-78; the 58th weft yarn interweaves with warp yarns 55-78; the 59th weft yarn interweaves with warp yarns 52-61 and 75-84; and the 60th weft yarn interweaves with warp yarns 49-57 and 79-88. 7. Warp yarns interweave; the 62nd weft yarn interweaves with warp yarns 46-54 and 82-90; the 62nd weft yarn interweaves with warp yarns 1-3, 43-51, and 85-90; the 63rd weft yarn interweaves with warp yarns 1-6, 40-48, and 88-90; the 64th weft yarn interweaves with warp yarns 1-9 and 37-45; the 65th weft yarn interweaves with warp yarns 4-12 and 34-42; the 66th weft yarn interweaves with warp yarns 7-16 and 30-39; the 67th weft yarn interweaves with warp yarns 10-36; the 68th weft yarn interweaves with warp yarns 13-33; and the 69th weft yarn interweaves with warp yarns 17-29 to form the second region 22, as shown in the reference. Figure 5The second horizontal stripe area 2, located in the 8th weft yarn of the 1st-90th warp yarn and the 114th-next cycle, also includes a first region 21 and a second region 22. Because the first region 21 and the second region 22 are interwoven by the alternating weft yarns, the second horizontal stripe area 2 includes two first regions 21 and a second region 22 located between the two first regions 21. The first region 21 and the second region 22 are wavy along the length of the fabric. Therefore, when the first region 21 and the second region 22 are stretched along the width of the fabric, the first region 21 and the second region 22 will unfold as the stretch increases, thereby buffering the weft spandex fibers in the first region 21 and the second region 22, reducing the direct stress on the spandex fibers, and increasing the elasticity of the fabric.
[0024] Because the width H1 of the first unit 11 along the fabric width direction is the width of 45 warp yarns, and the width H2 of the second unit 12 along the fabric width direction is also the width of 45 warp yarns, the width H1 of the first unit 11 along the fabric width direction is the same as the width H2 of the second unit 12 along the fabric width direction. The longest length of the first unit 11 along the fabric length direction is the length of 63 weft yarns, while the longest length of the second unit 12 along the fabric length direction is the length of 51 weft yarns. Therefore, along the fabric length direction, the length of the first unit 11 is longer than the length of the second unit 12. Along the fabric length direction, in the second horizontal stripe area 2, the average length of the first area 21 on both sides is the length of 3 weave points, and the longest length of the second area 22 is also the length of 3 weave points. Therefore, the length of the first area 21 is longer than the length of the second area 22. And because the second unit 12 has 2 plain weaves and 1 3-up-1-down weave... The fabric is woven in a cyclical pattern. The number of yarns in the plain weave structure is twice that of the 3-up-1-down weave structure. Since the first unit 11 is entirely plain weave, its density is greater than that of the second unit 12. As a result, the compression of the first unit 11 causes the second unit 12 to be higher than the first unit 11. Because the first region 21 consists entirely of warp points, while the second region 22 consists entirely of weft points, and since the warp is above the weft, the first region 21 is higher than the second region 22. This creates a unit structure with varying heights in the fabric. As the tension increases, the unit structures with varying heights are gradually flattened, allowing the stress to be evenly distributed rather than concentrated on a particular part of the yarn. When the external force is removed, the fabric combines with the unit structures with varying heights through a wave-like structure, allowing the warp and weft fibers to recover quickly. This reduces the risk of deformation and increases the fabric's fatigue resistance and shape retention.
