Description

Technical Field

[0001] This utility model relates to the field of fabrics, and more specifically, to a thermal insulation fabric. Background Technology

[0002] Existing heat-sealed down fabrics typically use adhesive layers to bond and fix the down. While this can reduce down leakage, over time and under the influence of the natural environment, the adhesive in the heat-sealed area will gradually age and lose its original stickiness, thus failing to effectively fix the down. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a thermal insulation fabric. The double-layer structure of the first region and the single-layer structure of the second region form a structural difference, and the first edge area of ​​the first region is connected to the second region. Thus, the second region not only constitutes the boundary of the first region, but also constrains the down on both sides of the first region along the length direction through its own structural compactness. Along the fabric width direction, the length centerline area of ​​the first region is connected to the second region. The difference in structure and density between the first and second regions causes the second edge area of ​​the first region to naturally form an angle through the internal stress of the second region. Combined with the first edge area, the first region forms a closed space, replacing the traditional pressing method and avoiding the instability of down confinement caused by adhesive aging.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a thermal insulation fabric, comprising a first region and a second region, wherein the first region and the second region are arranged alternately and cyclically along the length of the fabric, the first region comprising two first edge regions and two second edge regions, wherein the two first edge regions are respectively located at the upper end and the lower end of the first region, and the two second edge regions are respectively located at the left end and the right end of the first region, wherein the first edge regions and the second region are connected along the length of the fabric, and wherein the midpoint of the second region and the second edge regions are connected along the width of the fabric.

[0005] The present invention is further configured such that the second edge region includes two curved regions, and the two curved regions are symmetrically arranged along the fabric length direction with the midpoint of the second edge region as the reference line.

[0006] The present invention is further configured such that the curved area includes a first side, a second side, and a third side, wherein the first side and the second side form a first angle, and the second side and the third side form a second angle.

[0007] The present invention is further configured such that, along the length of the fabric, the first fold is far from the midpoint of the second edge region, and the second fold is close to the midpoint of the second edge region.

[0008] The present invention is further configured such that the first region is double-layered, the second region is single-layered, and a cavity is formed inside the first region, the height of which is 0.8cm-1.5cm.

[0009] The present invention is further configured such that the length of the first edge region is the same as the length of the second region, and the length of the second edge region is greater than the length of the first edge region.

[0010] The present invention is further configured such that the fabric has an 80-warp yarn and 88-weft yarn weave cycle, with 40 warp yarns and 80 weft yarns interwoven to form the first region, and 40 warp yarns and 8 weft yarns interwoven to form the second region.

[0011] The present invention is further configured such that the warp yarn of the fabric is made of 40S / 2 polyester fiber and the weft yarn of the fabric is made of 50S / 2 polyester fiber.

[0012] The present invention is further configured such that the warp density of the fabric is 400 threads / 10cm to 600 threads / 10cm, and the weft density of the fabric is 300 threads / 10cm to 450 threads / 10cm.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. The double-layer first region and the single-layer second region are interwoven together. The difference in structure between the first and second regions allows the second region to connect to the first edge area of ​​the first region and form the boundary of the first region. At the same time, the second region, with its own structural density, constrains both sides of the first region along the length of the fabric. Along the width of the fabric, the center line of the second edge area of ​​the first region connects with the second region. Through the difference in yarn and density between the first and second regions, the internal stress of the second region causes the second edge area of ​​the first region to naturally form an angle, thereby combining with the first edge area to form a naturally closed cavity in the first region, thus limiting the first region and solving the problem of down movement caused by the aging of the adhesive in traditional seam sealing.

[0015] 2. The first area adopts a double-layer 2:2 interlacing structure, while the second area has a single-layer interlacing structure. The interlacing density of the first area is lower than that of the second area, thus providing ample space for the down in the first area, resulting in better fluffiness and increased warmth of the fabric.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] like Figure 1 — Figure 5 As shown, this embodiment discloses a thermal insulation fabric, including a first region 1 and a second region 2. The fabric has an 80-warp yarn and 88-weft yarn weave cycle. In one weave cycle, the 1st to 20th warp yarns and the 1st to 40th weft yarns interweave to form the surface layer of the first region 1, the 1st to 20th warp yarns and the 1st to 40th weft yarns interweave to form the inner layer of the first region 1, the 21st to 40th warp yarns and the 1st to 18th weft yarns and the 23rd to 44th weft yarns interweave to form the surface layer of the first region 1, and the 21st to 40th warp yarns and the 1st to 18th weft yarns and the 23rd to 44th weft yarns interweave to form the inner layer of the first region 1. Therefore, 40 warp yarns and 80 weft yarns interweave to form the first region 1. In the first region 1, the warp and weft yarns of the surface layer and the inner layer of the first region 1 are arranged in a 2:2 ratio.

[0024] The first 20 warp yarns interweave with the 41st to 44th weft yarns to form the second region 2. Similarly, the 21st to 40th warp yarns interweave with the 19th to 23rd weft yarns to form the second region 2. Therefore, 40 warp yarns interweave with 8 weft yarns to form the second region 2. (Refer to...) Figure 5Because the "○" in the first region 1 represents the mark of the surface warp yarn being lifted when weaving the inner weft yarn of the first region 1, while there is no lifting mark in the second region 2, the first region 1 is interwoven as a double layer, and the second region 2 is interwoven as a single layer. Therefore, a cavity 3 is formed inside the first region 1. The height of the cavity 3 is 0.8cm-1.5cm, preferably 1.25cm. The cavity 3 provides sufficient space for the down, and the first region 1 and the second region 2 are interwoven as one, so that the fabric can maintain a reduced down leakage phenomenon.

[0025] Because the first region 1 and the second region 2 are formed by interlacing the same warp yarns with weft yarns at different positions, the first region 1 and the second region 2 are arranged alternately and cyclically along the length of the fabric. The first region 1 includes two first edge areas 11 and two second edge areas 12. The two first edge areas 11 are located at the upper and lower ends of the first region 1, respectively. Along the length of the fabric, the first edge areas 11 are connected to the second region 2. Because the first region 1 is double-layered and the second region 2 is single-layered, but the first region 1 and the second region 2 are interlaced as one, a double-layer and single-layer transition is formed between the first region 1 and the second region 2. The second region 2 is connected to the first edge area 11 of the first region 1, so that the second region 2 and the first edge area 11 are connected to form the boundary of the first region 1. At the same time, the single-layer structure of the second region 2 makes the yarn density greater than that of the double-layer structure of the first region 1. Thus, the second region 2 constrains the two sides of the first region 1 along the length of the fabric by its own single-layer structure density, thereby fixing the down in the cavity 3.

[0026] Two second edge regions 12 are located at the left and right ends of the first region 1, respectively. Along the fabric width direction, the second region 2 is connected to the midpoint of the second edge region 12. The fabric warp yarn uses 40S / 2 polyester fiber, and the fabric weft yarn uses 50S / 2 polyester fiber. The fabric warp density is 400-600 threads / 10cm, preferably 518 threads / 10cm. The fabric weft density is 300-450 threads / 10cm, preferably 366 threads / 10cm. Because the first region 1 is double-layered, the surface warp density of the first region 1 is 259 threads / 10cm. The inner layer warp density of region 1 is 259 threads / 10cm, the outer layer weft density of region 1 is 183 threads / 10cm, and the inner layer weft density of region 1 is 183 threads / 10cm. Region 2 is a single layer. Therefore, based on the same yarn count, the yarn density of region 2 is greater than that of region 1. Thus, the internal stress of region 2 causes the second edge region 12 to include two curved regions 121. The two curved regions 121 are symmetrically arranged along the fabric length with the midpoint of the second edge region 12 as the reference line. The curved region 121 includes a first edge 1211, a second edge 1212, and a third edge 1213. (Refer to...) Figure 5 One curved area 121 is pulled by the second region 2 formed by the interlacing of the 1st to 20th warp yarns and the 41st to 44th weft yarns, and the other curved area 121 is pulled by the second region 2 formed by the interlacing of the 21st to 40th warp yarns and the 19th to 23rd weft yarns. Therefore, during the cycle, the first edge 1211 and the second edge 1212 form a first angle 1214, and the second edge 1211 and the third edge 1213 form a second angle 1215. Along the length of the fabric, the first angle 1214 is far away from the midpoint of the second edge area 12, and the second angle 1215 is close to the midpoint of the second edge area 12. This causes the internal stress of the second region 2 to cause the second edge area 12 of the first region 1 to naturally form an angle, thereby combining with the first edge area 11 to form a naturally closed cavity in the first region 1. This forms fibers in the down inside the cavity 3 of the first region 1, thus solving the problem of down movement caused by the aging of the adhesive in traditional heat sealing.

[0027] Because the first edge zone 11 has a length of 20 warp yarns in a single layer of the first region 1, and the second edge zone 12 has a length of 40 weft yarns in a single layer of the first region 1, while the second region 2 has a length of 40 warp yarns, but because the warp density of a single layer of the second region 2 is the same as the warp density of a double layer of the first region 1, the length of the first edge zone 11 is the same as the length of the second region 2. This results in a greater constraint force of the second region 2 on the first edge zone 11. At the same time, the constraint force of the two curved areas 121 of the second edge zone 12 with the midpoint as the reference line on both sides of the second region 2 along the fabric length direction is also greater. This restricts the first edge 11 while making it less likely for the naturally formed folds of the second edge zone 12 to loosen, thereby avoiding structural deformation of the edge zone due to concentrated force. This allows the first region 1 to maintain constraint stability for a long time and effectively restricts the movement of down feathers.
