Abstract
Description
Technical Field
[0001] This utility model relates to the field of textiles, and more specifically, to a down fabric. Background Technology
[0002] Traditional down fabrics divide the down into sections using stitching. However, if the sections are too large, the down has room to move and migrate under gravity or during washing, gradually clumping up within the sections. If the sections are too small, the stitching density increases, allowing the down to escape through the needle holes, thus reducing the warmth of the down fabric. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a down fabric. In the first, third, and fourth regions, the first, third, and fifth units form recessed replacement seams, thereby fixing the down within the second, fourth, and sixth units and preventing it from clumping. Simultaneously, the high-low three-dimensional structure of the first, third, and fourth regions creates fixed points, resulting in a uniform thickness of down filling the second and fifth regions. Furthermore, the alternating arrangement of the first, third, and fourth regions creates a lateral dispersion trend for the down in the second and fifth regions, thus preventing the free movement of down within them. Therefore, the fabric will not leak or clump even after multiple washes. The third rectangular region is surrounded by the first and second rectangular regions in four directions. Therefore, when the down is compressed, a small portion of the down in the second and fifth regions surrounding the third rectangular region can temporarily enter the third rectangular region to form a buffer. After drying, patting disperses the down mesh in the second and fifth regions within the third rectangular region, thus maintaining the fabric's comfort and warmth.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a down fabric, comprising a first rectangular area, a second rectangular area and a third rectangular area, wherein along the fabric width direction, the long sides of two adjacent first rectangular areas are respectively connected to the short sides of the second rectangular areas, and along the fabric length direction, the long sides of two adjacent second rectangular areas are respectively connected to the short sides of the first rectangular areas, and the third rectangular area is formed by the two first rectangular areas and the two second rectangular areas.
[0005] The present invention is further configured such that the first rectangular area includes a first region, a second region and a third region, the first region and the second region are arranged alternately along the fabric width direction, the top end of the first region is connected to the bottom end of the first region and the third region, and the top end of the second region is connected to the bottom end of the second region and the third region.
[0006] The present invention is further configured such that the first region includes a first unit and a second unit, the first unit and the second unit are arranged alternately along the length of the fabric, and the first unit is lower than the second unit.
[0007] The present invention is further configured such that the third region includes a third unit and a fourth unit, the third unit and the fourth unit are arranged alternately along the fabric width direction, and the third unit is lower than the fourth unit.
[0008] The present invention is further configured such that the second rectangular area includes a fourth region and a fifth region, the fourth region and the fifth region being arranged alternately along the length of the fabric.
[0009] The present invention is further configured such that the fourth region includes a fifth unit and a sixth unit, the fifth unit and the sixth unit are arranged alternately along the fabric width direction, and the fifth unit is lower than the sixth unit.
[0010] The present invention is further configured such that the third rectangular area, the second area, the fifth area, the second unit, the fourth unit, and the sixth unit are of the same height.
[0011] The present invention is further configured such that, along the fabric width direction, a portion of the second unit and the fourth region are located on the same horizontal line, and along the fabric length direction, the fourth unit and the sixth unit are located on the same horizontal line.
[0012] The present invention is further configured such that the fabric is woven with 136 warp yarns and 142 weft yarns in one weave cycle, 57 warp yarns and 85 weft yarns interweave to form the first rectangular area, 79 warp yarns and 57 weft yarns interweave to form the second rectangular area, and 11 warp yarns and 14 weft yarns interweave to form the third rectangular area.
[0013] In summary, this utility model has the following beneficial effects:
[0014] In the first, third, and fourth regions, the indentations formed by the first, third, and fifth units prevent the down in the second, fourth, and sixth units from gathering longitudinally. The varying heights of the first, third, and fourth regions ensure that the down filling in the second and fifth regions is uniform. Furthermore, the alternating arrangement of the first, third, and fourth regions provides lateral restriction to the down in the second and fifth regions, preventing lateral gathering and thus preventing down leakage or clumping in the fabric. The third rectangular region is surrounded by the first and second rectangular regions in four directions. When the down is compressed, it can temporarily enter the third rectangular region to form a buffer, further enabling the fabric to retain down. Attached Figure Description

Detailed Implementation
[0020] 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.
[0021] like Figure 1 — Figure 4As shown, this embodiment discloses a down fabric. The fabric is woven with 136 warp yarns and 142 weft yarns in one weave cycle. Warp yarns 1-11 and 69-79 interweave with weft yarns 1-14 to form a third rectangular area 3. Warp yarns 1-11 and 69-79 interweave with weft yarns 72-85 to form a third rectangular area 3. Warp yarns 1-79 interweave with weft yarns 15-71 to form a second rectangular area 2. Warp yarns 12-68 interweave with weft yarns 1-14 and 72-142 to form a first rectangular area 1. Warp yarns 80-136 interweave with weft yarns 1-14 and 72-142 to form a third rectangular area 1. The first rectangular area 1 is formed by the interlacing of weft yarns 1-85, and the second rectangular area 2 is formed by the interlacing of warp yarns 1-11, warp yarns 69-136, and weft yarns 86-142. Therefore, the fabric includes the first rectangular area 1, the second rectangular area 2, and the third rectangular area 3. When the long side of the first rectangular area 1 is located at the 80th warp yarn and the 136th warp yarn, the short side of the second rectangular area 2 is located at the 1st warp yarn and the 79th warp yarn. When the long side of the first rectangular area 1 is located at the 12th warp yarn and the 68th warp yarn, the short side of the second rectangular area 2 is located at the 11th warp yarn and the 69th warp yarn. Therefore, in... In the fabric cycle, along the fabric width direction, the long sides of two adjacent first rectangular areas 1 are connected to the short sides of second rectangular areas 2. When the long side of the first rectangular area 2 is located at the 15th and 71st weft yarns, the short side of the first rectangular area 1 is located at the 14th and 72nd weft yarns. When the long side of the second rectangular area 2 is located at the 86th and 142nd weft yarns, the short side of the first rectangular area 1 is located at the 1st and 85th weft yarns. Therefore, in the fabric cycle, along the fabric length direction, the long sides of two adjacent second rectangular areas 2 are connected to the short sides of the first rectangular area 1. When the third rectangular area 3 is located at the intersection of the 69th-79th warp yarns and the 72nd-85th weft yarns, the two sides of the third rectangular area 3 along the width of the fabric are adjacent to the first rectangular area 1 respectively, and the two sides of the third rectangular area 3 along the length of the fabric are adjacent to the second rectangular area 2 respectively. Therefore, the third rectangular area 3 formed by the two first rectangular areas 1 and the two second rectangular areas 2 makes the first rectangular area 1, the second rectangular area 2 and the third rectangular area 3 periodically connected, so that the warp and weft yarns of the fabric form a stable structure, thereby ensuring the overall dimensional stability and strength of the fabric.
[0022] Within the first rectangular area 1 formed by the interweaving of warp yarns 12-68 with weft yarns 1-14 and 72-142, within the range of 57 warp yarns and 85 weft yarns, warp yarns 12-23 interweave with weft yarns 1-11 and 75-142 to form a second area 12; warp yarns 24-26 interweave with weft yarns 1-11 and 75-142 to form a first area 11; warp yarns 27-38 interweave with weft yarns 1-11 and 72-142 to form a second area 12; warp yarns 39-41 interweave with weft yarns 1-11 and 75-142 to form a first area 11; and warp yarns 42-53 interweave with weft yarns 1-11 and 72-142... The yarns interweave to form a second region 12. Warp yarns 54-56 interweave with weft yarns 1-11 and 75-142 to form a first region 11. Warp yarns 57-68 interweave with weft yarns 1-11 and 72-142 to form a second region 12. Warp yarns 12-68 interweave with weft yarns 12-14 to form a third region 13. Warp yarns 12-68 interweave with weft yarns 72-74 to form a third region 13. Within the first rectangular region 1 formed by the interweaving of 57 warp yarns and 85 weft yarns, warp yarns 80-91 interweave with weft yarns 4-82 to form a second region 12. Warp yarns 92-94 interweave with weft yarns 4-8... Two weft yarns interweave to form the first region 11. Warp yarns 95-106 interweave with weft yarns 4-84 to form the second region 12. Warp yarns 107-109 interweave with weft yarns 4-84 to form the first region 11. Warp yarns 110-121 interweave with weft yarns 4-84 to form the second region 12. Warp yarns 122-124 interweave with weft yarns 4-84 to form the first region 11. Warp yarns 125-136 interweave with weft yarns 4-84 to form the second region 12. Warp yarns 80-136 interweave with weft yarns 1-3 to form the third region 13. Warp yarns 80-136 interweave with weft yarns 83-85 to form the third region 13. Therefore, the first rectangular region 1 includes the first region 1. 1. Regions 12 and 13 are interwoven because regions 11 and 12 are woven with warp yarns at different positions and weft yarns at the same position. Therefore, regions 11 and 12 are arranged alternately along the fabric width. Region 13 is interwoven with regions 11 and 12 through warp yarns at the same position and weft yarns at different positions. Furthermore, the weft yarns of region 13 are adjacent to the weft yarns of regions 11 and 12. Therefore, the top and bottom of region 11 connect to region 13, and the top and bottom of region 12 connect to region 13. In the warp and weft yarns that form region 11,The 24th-26th warp yarns, the 39th-41st warp yarns, the 54th-56th warp yarns, and the 4th-11th weft yarns, the 76th-83rd weft yarns, the 86th-97th weft yarns, the 101st-112th weft yarns, the 116th-127th weft yarns, and the 131st-142nd weft yarns interweave to form the first unit 111. The 92nd-94th warp yarns, the 107th-109th warp yarns, the 122nd-124th warp yarns, and the 4th-11th weft yarns, the 15th-26th weft yarns, the 30th-41st weft yarns, the 45th-56th weft yarns, the 60th-71st weft yarns, and the 75th-82nd weft yarns interweave to form the first unit 111. The 24th-26th warp yarns, the 39th-41st warp yarns, the 54th-56th weft yarns, and the 1st-3rd weft yarns, the 83rd-85th weft yarns, the 98th-100th weft yarns, and the 11th-127th weft yarns interweave to form the first unit 111. The second unit 112 is formed by interlacing weft yarns 3-115 and 128-130. The second unit 112 is formed by interlacing warp yarns 92-94, 107-109, and 122-124 with weft yarns 12-14, 27-29, 42-44, 57-59, and 72-74. Therefore, the first region 11 includes the first unit 111 and the second unit 112, and the first unit 111 and the second unit 112 are arranged alternately along the fabric length. In the warp and weft yarns that interlaced to form the third region 13, the third unit 131 is formed by interlacing warp yarns 15-31, 35-45, and 49-65 with weft yarns 12-14 and 72-74. Warp yarns 2-14, 32-34, 46-48, and 66-68 interweave with weft yarns 12-14 and 72-74 to form the fourth unit 132. Warp yarns 83-99, 103-113, and 117-133 interweave with weft yarns 1-3 and 83-85 to form the third unit 131. Warp yarns 80-82, 100-102, 114-116, and 134-136 interweave with weft yarns 1-3 and 83-85 to form the fourth unit 132. Therefore, the third region 13 includes the third unit 131 and the fourth unit 132, and the third unit 131 and the fourth unit 132 are arranged alternately along the fabric width direction because the first unit 11 Unit 1 and the third unit 131 are plain weave, while the second unit 112 and the fourth unit 132 have three weave points for the longest float. Therefore, the plain weave of the first unit 111 will arch the float of the second unit 112, and the plain weave of the third unit 131 will arch the float of the fourth unit 132. Thus, the first unit 111 is lower than the second unit 112, and the third unit 131 is lower than the fourth unit 132. The double warp and single weft weave of the second region 12 makes the second region 12 denser than the plain weave of the first unit 111. Therefore, the second region 12 will also bulge upwards due to the plain weave of the first unit 111. However, due to the constraint of the first unit 111, the second region 12 is at the same height as the second unit 112 and the fourth unit 132. Therefore, in the first region 11,Along the fabric length direction, the indentation of the first unit 111 restricts down movement to within the second unit 112, thus significantly reducing long-distance down leakage in the first region 11 in the longitudinal direction. In the third region 13, along the fabric width direction, the indentation of the third unit 131 restricts down movement to within the fourth unit 132, thus significantly reducing long-distance down leakage in the third region 13 in the transverse direction. The second region 12 is separated from the first region 11 along the fabric width direction and from the third region 13 along the fabric length direction. Therefore, along the fabric width direction, the alternating arrangement of the first unit 111 and the second region 112 within the first region 11 creates a physical barrier to the second region 12. The fabric is divided into three sections. First section 11 replaces the seam, preventing down feathers from escaping from second section 12 and second unit 112. Similarly, along the fabric length, the alternating arrangement of third unit 131 and fourth unit 132 in third section 13 physically blocks down feathers from escaping from second section 12. Furthermore, first section 11 forms barriers on both sides of second section 12 laterally, and third section 13 forms barriers on both sides of second section 12 longitudinally. This allows down feathers to be evenly filled inside second section 12 while preventing free movement of the down feathers. Therefore, the fabric will not leak down or clump after multiple washes.
[0023] Within the second rectangular area 2 formed by the interweaving of warp yarns 1-79 and weft yarns 15-71, within the range of the interweaving of 79 warp yarns and 57 weft yarns, warp yarns 1-79 interweave with weft yarns 15-26 to form a fifth region 22; warp yarns 1-79 interweave with weft yarns 27-29 to form a fourth region 21; warp yarns 1-79 interweave with weft yarns 30-41 to form a fifth region 22; warp yarns 1-79 interweave with weft yarns 42-44 to form a fourth region 21; warp yarns 1-79 interweave with weft yarns 45-56 to form a fifth region 22; weft yarns 57-59 interweave to form a fourth region 21; and weft yarns 60-71 interweave to form a fifth region 22. Also within the area formed by the interweaving of warp yarns 1-11, warp yarns 69-136, and weft yarns 86-142... Within the interlacing range of the 79 warp yarns and 57 weft yarns forming the second rectangular area 2, warp yarns 1-11, warp yarns 69-136, and weft yarns 86-97 interlace to form the fifth region 22; warp yarns 1-11, warp yarns 69-136, and weft yarns 98-100 interlace to form the fourth region 21; warp yarns 1-11, warp yarns 69-136, and weft yarns 101-112 interlace to form the fifth region 22; warp yarns 1-11, warp yarns 69-136, and weft yarns 113-115 interlace to form the fourth region 21; warp yarns 1-11, warp yarns 69-136, and weft yarns 116-127 interlace to form the fifth region 22; warp yarns 1-11, warp yarns 69-136, and weft yarns 128-137 interlace to form the fifth region 22; and warp yarns 1-11, warp yarns 69-136, and weft yarns 128-137 interlace to form the fifth region 22. The fourth region 21 is formed by the interlacing of the 0th weft yarn, and the fifth region 22 is formed by the interlacing of the 1st-11th warp yarn, the 69th-136th warp yarn, and the 131st-142nd weft yarn. Therefore, the second rectangular region 2 includes the fourth region 21 and the fifth region 22. Because the fourth region 21 and the fifth region 22 are interlaced by weft yarns at different positions and warp yarns at the same positions, the fourth region 21 and the fifth region 22 are arranged alternately along the length of the fabric. In the warp and weft yarns that interlaced to form the fourth region 21, the 1st-11th warp yarn, the 15th-31st warp yarn, the 35th-45th warp yarn, the 49th-65th warp yarn, the 69th-79th warp yarn, and the 27th-29th weft yarn, the 42nd-44th weft yarn, and the 57th-59th weft yarn interlaced to form the fifth unit 211. The fifth unit 211 is formed by interlacing warp yarns 69-79, 83-99, 103-113, and 117-133 with weft yarns 98-100, 113-115, and 128-130. The sixth unit 212 is formed by interlacing warp yarns 12-14, 32-34, 46-48, and 66-68 with weft yarns 27-29, 42-44, and 57-59. The sixth unit 212 is formed by interlacing warp yarns 80-82, 100-102, 114-116, and 134-136 with weft yarns 98-100, 113-115, and 128-130.Therefore, the fourth region 21 includes the fifth unit 211 and the sixth unit 212, which are arranged alternately along the fabric width. Because the fifth unit 211 is plain weave, and the sixth unit 212 has a maximum float length of 3 weave points, the plain weave of the fifth unit 211 will arch the float length of the sixth unit 212. Therefore, the fifth unit 211 is lower than the sixth unit 212. The single warp and double weft weave of the fifth region 22 makes the fifth region 22 denser than the plain weave of the fifth unit 211. Therefore, the fifth region 22 will also be denser because of the fifth single warp and double weft weave. The plain weave of unit 211 is raised upwards, but due to the restriction of unit 212, the fifth region 22 is at the same height as the sixth unit 212. Therefore, in the fourth region 21, along the fabric width direction, the indentation of unit 211 forces the down to move only within unit 212, thus significantly reducing long-distance down leakage in the fourth region 21 in the lateral direction. Meanwhile, the fifth region 22 is separated from the fourth region 21 along the fabric length direction. The weave of the fifth region 22 is opposite to that of the second region 12 along the fabric width direction. Therefore, along the fabric length direction, the fourth region... The alternating arrangement of the fifth unit 211 and the sixth unit 212 within domain 21 physically isolates the fifth region 22, and the fifth unit 211 is connected to the third region 13. Simultaneously, the fourth region 21 and the third region 13 replace the seams, preventing the down feathers in the fifth region 22 and the sixth unit 212 from escaping. Similarly, along the fabric width, the warp and weft of the fifth region 22 and the second region 12 are opposite; the sixth unit 212 is plain weave, while the second region 12 is double warp and single weft. Therefore, the edge warp and weft yarns of the fifth region 22, the sixth unit 212, and the second region 12 are... The increased variation in stitching creates a lateral physical barrier between the second region 12 and the fifth region 22 and the sixth unit 212. Simultaneously, by replacing the stitching with variations in the weave, the down feathers within the fifth region 22 and the sixth unit 212 cannot escape. Furthermore, the third region 13 and the fourth region 21 form barriers on both longitudinal sides of the fifth region 22, while the second region 12 forms barriers on both transverse sides. This allows for even filling and containment within the fifth region 22, and enables the down feathers to move freely within it. Therefore, the fabric will not leak down or clump after multiple washes.
[0024] Within the 11 warp and 14 weft yarns interwoven in the third rectangular area 3 formed by the interweaving of warp yarns 1-11, warp yarns 69-79, and weft yarns 1-14, and within the 11 warp and 14 weft yarns interwoven in the third rectangular area 3 formed by the interweaving of warp yarns 1-11, warp yarns 69-79, and weft yarns 72-85, each third rectangular area 3 is formed by a single warp and double weft weave. Therefore, the structure of the third rectangular area 3 is the same as that of the fifth region 22. Thus, the structure of the third rectangular area 3 and the fifth region 22 encloses the first rectangular area 1 in the middle, thereby restricting the movement of down feathers within the first rectangular area 1. Because the third rectangular area... Although the structure of Zone 3 is the same as that of Zone 22, the third rectangular zone 3 is parallel to the first rectangular zone 1, thus creating a staggered structure between the second rectangular zone 2 and the third rectangular zone 3. The structures of the second rectangular zone 2 and the third rectangular zone 3 are opposite to those of the first rectangular zone 1, thereby restricting the movement of down within the second rectangular zone 2 and the third rectangular zone 3. Consequently, the down within each rectangular zone does not move, and the down within each rectangular zone remains within its original rectangular zone. Therefore, when patted after washing, the down will only fluff up within its original rectangular zone, thus preventing the down from clumping due to excessive down accumulation after washing, thereby maintaining the comfort and warmth of the fabric.
[0025] Along the fabric width, some parts of the second unit 112 and the fourth region 21 use the same weft yarn interweaving, therefore some parts of the second unit 112 and the fourth region 21 are located on the same horizontal line. Along the fabric length, the fourth unit 132 and the sixth unit 212 use the same warp yarn interweaving, therefore the fourth unit 132 and the sixth unit 212 are located on the same horizontal line. The third rectangular region 3 and the fifth region 22 use the same weave, therefore the third rectangular region 3, the fifth region 22 and the sixth unit 212 are at the same height. Although the weave of the second region 12 is opposite to that of the third rectangular region 3, the second region 12 and the third rectangular region 3 use the same float weave, therefore the second region... Region 12 is at the same height as the third rectangular region 3. Since the second region 12 is at the same height as the second unit 112 and the fourth unit 132, the third rectangular region 3, the second region 12, the fifth region 22, the second unit 112, the fourth unit 132 and the sixth unit 212 are at the same height, thus forming a three-dimensional structure of high and low in the fabric. Furthermore, the first region 11, the third region 13 and the fourth region 21 form a constraint, thus making the down filling thickness in the third rectangular region 3, the second region 12 and the fifth region 22 uniform. At the same time, it restricts the free movement of the down in the third rectangular region 3, the second region 12 and the fifth region 22, thereby reducing the phenomenon of down leakage and clumping in the overall fabric.
