AI Technical Summary
[0002]传统保暖面料多依赖于增加面料厚度来实现，但往往会因为增加了面料的厚度而导致面料的重量增加，使面料笨重，导致面料的透气性差
[0015]第一单元的第二区域低于第二区域内部的第一区域，第二单元的第四区域低于第四区域内部的第三区域，因此第一单元与第二单元连接时，第一区域与第二区域、第三区域与第四区域的高低差在面料表面形成多个腔体，当面料与人体接触使，凸起的第一区域与第三区域会形成充满静止空气的腔体，热量要流失时会被静止的空气所阻挡，从而减少热量流失，而第二区域与第四区域的结构紧密性大于第一区域与第三区域，且第二区域与第四区域低于第一区域与第三区域，因此第二区域与第四区域相对紧密的结构可以更好的形成毛细作用，增加面料的透气性。

Description
Technical Field
[0001] This utility model relates to the field of fabrics, and more specifically, to a thermal insulation fabric. Background Technology
[0002] Traditional thermal insulation fabrics often rely on increasing fabric thickness, but this often leads to increased fabric weight, making the fabric bulky and resulting in poor breathability. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a thermal fabric. The second region of the first unit is the first region, and the first region is higher than the second region. The fourth region of the second unit is the third region, and the third region is higher than the fourth region. The entire fabric is formed by connecting the first and second units. Therefore, through the height difference between the first and second regions and the third and fourth regions, multiple cavities are formed on the surface of the fabric. The raised structures of the first and third regions form cavities filled with still air when the fabric comes into contact with the human body. When heat is about to be lost, it will be blocked by the still air, thereby increasing the warmth of the fabric. The structure of the second and fourth regions is more compact than that of the first and third regions, and the second and fourth regions are lower than the first and third regions. Therefore, the relatively compact structure of the second and fourth regions can better absorb and accelerate the evaporation of moisture from the skin surface through capillary action, thereby increasing the breathability of the fabric.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a thermal insulation fabric, comprising a first unit and a second unit, wherein the first unit is octagonal and the second unit is rectangular, the length of the first unit and the second unit along the fabric length direction is greater than the width along the fabric width direction, the long straight side of the second unit is connected to the long straight side of the first unit, and the short straight side of the second unit is connected to the short straight side of the first unit, the first unit includes a first region and a second region, the first region being located in the middle of the area enclosed by the second region, and the second unit includes a third region and a fourth region, the third region being located in the middle of the area enclosed by the fourth region.
[0005] The present invention is further configured such that the first region is higher than the second region, the third region is higher than the fourth region, and the first region and the third region are at the same height.
[0006] The present invention is further configured such that the width of the first unit along the fabric width direction is greater than the width of the second unit, and the length of the first unit along the fabric length direction is greater than the length of the second unit.
[0007] The present invention is further configured such that the width of the second region is equal to the width of the fourth region.
[0008] The present invention is further configured such that both the first region and the second region are octagonal, and the angle of the hypotenuse of both the first region and the second region is 30 degrees.
[0009] The present invention is further configured such that the fabric is woven with 78 warp yarns and 132 weft yarns in one weave cycle, 50 warp yarns and 77 weft yarns in one weave cycle to form the first unit, and 28 warp yarns and 55 weft yarns in one weave cycle to form the second unit.
[0010] The present invention is further configured such that, in the first unit, 42 warp yarns and 69 weft yarns interweave to form the first region.
[0011] The present invention is further configured such that, in the second unit, 20 warp yarns and 47 weft yarns interweave to form the third region.
[0012] The present invention is further configured such that the warp yarn of the fabric is made of 32-count wool fiber and the weft yarn of the fabric is made of 50D polyester fiber.
[0013] The present invention is further configured such that the warp density of the fabric is 80 threads / inch and the weft density is 74 threads / inch.
[0014] In summary, this utility model has the following beneficial effects:
[0015] The second region of the first unit is lower than the first region inside the second region, and the fourth region of the second unit is lower than the third region inside the fourth region. Therefore, when the first unit and the second unit are connected, the height difference between the first region and the second region, and between the third region and the fourth region, forms multiple cavities on the fabric surface. When the fabric comes into contact with the human body, the raised first region and the third region will form cavities filled with still air. When heat is about to be lost, it will be blocked by the still air, thereby reducing heat loss. The structure of the second region and the fourth region is more compact than that of the first region and the third region, and the second region and the fourth region are lower than the first region and the third region. Therefore, the relatively compact structure of the second region and the fourth region can better form capillary action and increase the breathability of the fabric. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figure 1 — Figure 4As shown, this embodiment discloses a thermal insulation fabric. The fabric is woven with 78 warp yarns and 132 weft yarns in one weave cycle. The 1st warp yarn and the 36th warp yarn are interwoven with the 1st-62nd and 126th-132nd weft yarns; the 2nd warp yarn and the 35th warp yarn are interwoven with the 1st-63rd and 125th-132nd weft yarns; the 3rd warp yarn and the 34th warp yarn are interwoven with the 1st-64th and 124th-132nd weft yarns; the 4th warp yarn and the 33rd warp yarn are interwoven with the 1st-65th and 123rd-132nd weft yarns; the 5th-32nd warp yarns are interwoven with the 1st-66th and 122nd-132nd weft yarns; and the 37th warp yarn, the 36th warp yarn, and the 36th warp yarn are interwoven with the 1st-62nd and 126th-132nd weft yarns; ...8th warp yarn, the 36th warp yarn, and the 36th warp yarn are interwoven with the 1 Warp yarn 78 interweaves with weft yarns 1-61 and 127-132; warp yarns 38 and 77 interweave with weft yarns 1-60 and 128-132; warp yarns 39 and 76 interweave with weft yarns 1-59 and 129-132; warp yarns 40 and 75 interweave with weft yarns 1-58 and 130-132; warp yarns 41 and 74 interweave with weft yarns 1-57 and 131-132; warp yarns 42 and 73 interweave with weft yarns 1-56 and 132; warp yarns 43 and 72 interweave with weft yarns 1-55. The interlacing forms Unit 1: Warp 33 and warp 4 interlace with weft yarns 67-121; warp 34 and warp 3 interlace with weft yarns 66-122; warp 35 and warp 2 interlace with weft yarns 65-123; warp 36 and warp 1 interlace with weft yarns 64-124; warp 37 and warp 78 interlace with weft yarns 63-125; warp 38 and warp 77 interlace with weft yarns 62-126; warp 39 and warp 76 interlace with weft yarns 61-127; warp 40 and warp 75 interlace with weft yarns 60-128; warp 41 and warp 7... 4 warp yarns interweave with weft yarns 59-129, warp yarns 42 and 73 interweave with weft yarns 58-130, warp yarns 43 and 72 interweave with weft yarns 57-131, warp yarns 44-71 interweave with weft yarns 56-132 to form unit 1, warp yarns 5-32 interweave with weft yarns 67-121 to form unit 2, and warp yarns 44-71 interweave with weft yarns 1-55 to form unit 2. Therefore, the fabric includes unit 1 and unit 2, and 50 warp yarns interweave with 77 weft yarns to form unit 1, and 28 warp yarns interweave with 55 weft yarns to form unit 2.
[0023] In Unit 1, the number of weft yarn interlacing threads gradually increases when warp yarns 1-5 interlac with weft yarns 62-66; gradually increases when warp yarns 1-5 interlac with weft yarns 122-126; gradually increases when warp yarns 72-78 interlac with weft yarns 55-61; gradually increases when warp yarns 72-78 interlac with weft yarns 127-132; gradually decreases when warp yarns 32-43 interlac with weft yarns 55-66; gradually decreases when warp yarns 32-43 interlac with weft yarns 122-132; gradually increases when warp yarns 33-44 interlac with weft yarns 56-67; and gradually increases when warp yarns 33-44 interlac with weft yarns 121-132. When warp yarns 71-78 interweave with weft yarns 56-63, the number of interlacing weft yarns gradually decreases. When warp yarns 71-78 interweave with weft yarns 125-132, the number of interlacing weft yarns gradually decreases. When warp yarns 1-4 interweave with weft yarns 64-67, the number of interlacing weft yarns gradually decreases. When warp yarns 1-4 interweave with weft yarns 121-124, the number of interlacing weft yarns gradually decreases. Therefore, unit 1 is octagonal, while unit 2 is rectangular. This is because unit 1 has 77 weft yarns along the fabric length direction and 50 warp yarns along the fabric width direction. Unit 2 has 55 weft yarns along the fabric length direction and 28 warp yarns along the fabric width direction. Therefore, the length of unit 1 and unit 2 along the fabric length direction is greater than their width along the fabric width direction.
[0024] When the long straight edge of Unit 1 is located at the 43rd and 72nd warp yarns, the long straight edge of Unit 2 is located at the 44th and 71st warp yarns. When the long straight edge of Unit 1 is located at the 4th and 33rd warp yarns, the long straight edge of Unit 2 is located at the 5th and 32nd warp yarns. Therefore, the long straight edge of Unit 2 connects with the long straight edge of Unit 1. When the short straight edge of Unit 1 is located at the 66th and 122nd weft yarns, the short straight edge of Unit 2 is located at the 67th and 71st weft yarns. At the 121st weft yarn, when the short straight edge of the first unit 1 is located at the 132nd and 56th weft yarns, the short straight edge of the second unit 2 is located at the 1st and 55th weft yarns. Therefore, the short straight edge of the second unit 2 is connected to the short straight edge of the first unit 1. Furthermore, the width of the first unit 1 along the fabric width direction is greater than the width of the second unit 2, and the length of the first unit 1 along the fabric length direction is greater than the length of the second unit 2. Thus, the first unit 1 and the second unit 2 form multiple geometric regions on the fabric surface.
[0025] In Unit 1, warp yarns 1 and 36 interweave with weft yarns 1-57 and 131-132; warp yarns 2 and 35 interweave with weft yarns 1-58 and 130-132; warp yarns 3 and 34 interweave with weft yarns 1-59 and 129-132; warp yarns 4 and 33 interweave with weft yarns 1-60 and 128-132; warp yarns 5 and 32 interweave with weft yarns 1-61 and 127-132; warp yarns 6-31 interweave with weft yarns 1-62 and 126-132; warp yarns 37 and 78 interweave with weft yarns 1-56 and 132; and warp yarns 38 and 77 interweave with weft yarns 1-55. The interlacing process involves the 39th and 76th warp yarns interlacing with the 2nd to 54th weft yarns to form the first region 11; the 1st and 36th warp yarns interlacing with the 58th to 62nd and 126th to 130th weft yarns; the 2nd and 35th warp yarns interlacing with the 59th to 63rd and 125th to 129th weft yarns; the 3rd and 34th warp yarns interlacing with the 60th to 64th and 124th to 128th weft yarns; the 4th and 33rd warp yarns interlacing with the 61st to 65th and 123rd to 127th weft yarns; the 5th and 32nd warp yarns interlacing with the 62nd to 66th and 122nd to 126th weft yarns; the 6th to 31st warp yarns interlacing with the 63rd to 66th and 122nd to 125th weft yarns; and the 37th warp yarn interlacing with the 57th to 61st and 12th to 54th weft yarns. The warp yarns 7-131 interweave; the 38th warp yarn interweaves with the 56th-60th and 128th-132nd weft yarns; the 39th and 76th warp yarns interweave with the 1st, 55th-59th, and 129th-132nd weft yarns; the 40th and 75th warp yarns interweave with the 1st-58th and 130th-132nd weft yarns; the 41st and 74th warp yarns interweave with the 1st-57th and 131st-132nd weft yarns; the 42nd and 73rd warp yarns interweave with the 1st-56th and 132nd weft yarns; the 43rd and 72nd warp yarns interweave with the 1st-55th weft yarns to form the second region 12; the 37th and 78th warp yarns interweave with the 68th-120th weft yarns; the 38th and 77th warp yarns interweave with the 67th-121st weft yarns... The yarns interweave as follows: warp 39 and warp 76 interweave with weft yarns 66-122; warp 40 and warp 75 interweave with weft yarns 65-123; warp 41 and warp 74 interweave with weft yarns 64-124; warp 42 and warp 73 interweave with weft yarns 63-125; warp 43 and warp 72 interweave with weft yarns 62-126; warp 44 and warp 71 interweave with weft yarns 61-127; warp 45-70 interweave with weft yarns 60-128 to form the first region 11; warp 4 and warp 33 interweave with weft yarns 67-121; warp 3 and warp 34 interweave with weft yarns 66-122; warp 2 and warp 35 interweave with weft yarns 65-123.Warp 1 and warp 36 interweave with weft yarns 64-124; warp 37 and warp 78 interweave with weft yarns 63-67 and 121-125; warp 38 and warp 77 interweave with weft yarns 62-66 and 122-126; warp 39 and warp 76 interweave with weft yarns 61-65 and 123-127; warp 4... Warp 0 and warp 75 interweave with weft yarns 60-64 and 124-128; warp 41 and warp 74 interweave with weft yarns 59-63 and 125-129; warp 42 and warp 73 interweave with weft yarns 58-62 and 126-130; warp 43 and warp 72 interweave with weft yarns 57-61 and 127-130. The first unit 1 consists of two regions: the 44th and 71st warp yarns interweave with the 56th-60th and 128th-132nd weft yarns, and the 45th-70th warp yarns interweave with the 56th-59th and 129th-132nd weft yarns to form the second region 12. Therefore, the first unit 1 includes both the first region 11 and the second region 12, and the first region 11 is located within the first unit 1. The first region 11 is formed by the interweaving of 42 warp yarns and 69 weft yarns. Because the warp and weft yarns of the second region 12 are located outside the warp and weft yarns of the first region 11, the first region 11 is located in the middle of the area enclosed by the second region 12. Both the first region 11 and the second region 12 are octagonal, and the hypotenuse angles of both regions are 30 degrees, thus maintaining the structural stability of the first region 11 and the second region 12.
[0026] In Unit 2, warp yarns 9-28 interweave with weft yarns 71-117 to form the third region 21; warp yarns 5-8 and 29-32 interweave with weft yarns 67-121; warp yarns 9-28 interweave with weft yarns 67-70 and 118-121 to form the fourth region 22; warp yarns 48-67 interweave with weft yarns 5-51 to form the third region 21; warp yarns 44-47 and 68-71 interweave with weft yarns 1-55; and warp yarns 48-67 interweave with weft yarns 1-4 and 52-55. The weaving forms the fourth region 22. Therefore, the second unit 2 includes the third region 21 and the fourth region 22, and is located within the second unit 2. 20 warp yarns and 47 weft yarns interweave to form the third region 21, and 8 warp yarns and 8 weft yarns interweave to form the fourth region 22. Because the warp and weft yarns of the fourth region 22 are located outside the warp and weft yarns of the third region 21, the third region 21 is located in the middle of the area enclosed by the fourth region 22. Because the width of the straight edge of the second region 12 is the width of 4 yarns, and the width of the fourth region 22 is also the width of 4 yarns, therefore the second region 1... The width of region 2 is equal to the width of region 22. Since both regions 12 and 22 use plain weave, while regions 11 and 21 use a 1-up-1-down-3-up-1-down-1-up-3-down sponge weave, the density of regions 12 and 22 is greater than that of regions 11 and 21. Therefore, region 11 is compressed by the yarn density of region 12 to form a cavity, and region 21 is compressed by the yarn density of region 22 to form a cavity. The width of region 2 is equal to that of region 4. Since regions 11 and 22 both use plain weave, while regions 11 and 21 both use a 1-up-1-down-3-down sponge weave, the density of regions 12 and 22 is greater than that of regions 11 and 21. Since the fabric has the same structure, the first region 11 is higher than the second region 12, the third region 21 is higher than the fourth region 22, and the first region 11 and the third region 21 are at the same height. This makes the first region 11 and the third region 21 form multiple cavities on the fabric surface. When the fabric comes into contact with the human body, the raised structure of the first region 11 and the third region 21 forms cavities filled with still air. When heat is about to be lost, the still air in the cavities of the first region 11 and the third region 21 will block the heat loss, thereby increasing the warmth retention of the fabric.
[0027] The fabric warp yarns are made of 32-count wool fiber, and the weft yarns are made of 50D polyester fiber. The warp density is 80 threads / inch, and the weft density is 74 threads / inch. Because the density of the second region 12 and the fourth region 22 is greater than that of the first region 11 and the third region 21, and the density of the second region 12 is lower than that of the first region 11, and the density of the fourth region 22 is lower than that of the third region 21, the combination of warp and weft yarns creates a capillary effect between the second region 12, the fourth region 22 and the first region 11, and the third region 21 through the density. In addition, wool fiber has good moisture absorption and moisture wicking properties, so the second region 12 and the fourth region 22 absorb and remove moisture from the skin surface, thereby increasing the breathability of the fabric. Without increasing the thickness of the fabric, the fabric structure increases the amount of still air, thereby increasing the warmth of the fabric while maintaining its lightweight.
