A type of fabric

Abstract

This utility model discloses a fabric comprising a striped area and a base fabric area, which are arranged alternately and cyclically along the length of the fabric. The striped area includes two symmetrically distributed second regions and two first regions connecting the second regions. The first regions are arranged in a matrix within the striped area, and adjacent first regions are arranged in a stepped pattern along the width of the fabric. The first and second regions are higher than the base fabric area, and a leather surface is located above the striped area and the base fabric area. In a wet state, the first regions provide space for the weft yarns in the base fabric area to expand, and the second regions provide space for the warp yarns in the base fabric area to expand. In a dry state, the first regions contract due to the restraint of the weft yarns in the base fabric area, and the second regions contract due to the restraint of the warp yarns in the base fabric area, thereby preventing cracking and deformation of the leather surface caused by deformation of the base fabric.

Description

Technical Field

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

[0002] Most leather fabrics on the market today have a flat backing fabric formed by a single weave. In humid environments, the backing fabric expands due to moisture absorption due to its flat structure, and shrinks when dry, causing deformation. This repeated deformation of the backing fabric can easily lead to cracking and deformation of the leather surface, thus affecting the lifespan of the leather fabric. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fabric in which the yarns inside the fabric absorb water and swell when wet. Because the interlacing angle between the yarns in the second region is greater than that in the first region, the gaps between the yarns in the second region are larger than those in the first region. This allows for a gap between the second and first regions to accommodate the yarn expansion. Simultaneously, the base fabric area has a plain weave structure, minimizing the gaps between the yarns. Therefore, along the length of the fabric, the first region, using the same warp yarns as the base fabric area, provides sufficient space for the weft yarns within the base fabric area to expand. In the fabric width direction, the second region, using the same weft yarn as the base fabric, provides a certain space for the warp yarns in the base fabric area to expand. When dry, the second region and the first region are higher than the base fabric area. In the fabric length direction, the first region, using the same warp yarn as the base fabric area, restrains the weft yarns in the base fabric area to shrink. In the fabric width direction, the second region, using the same weft yarn as the base fabric area, restrains the warp yarns in the base fabric area to shrink. This reduces the stress difference caused by uneven expansion and contraction in different areas of the fabric, and avoids cracking and deformation of the leather surface due to deformation of the base fabric.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a fabric comprising a striped area and a base fabric area, wherein the striped area and the base fabric area are arranged alternately and cyclically along the length of the fabric, the striped area comprising two symmetrically distributed second areas and two first areas connecting the second areas, the first areas being arranged in a matrix and located in the striped area, adjacent first areas being arranged in a stepped manner along the width of the fabric, the first areas and the second areas being higher than the base fabric area, and a leather surface being provided above the striped area and the base fabric area.

[0005] The present invention is further configured such that the second region is a parallelogram, the first region is a rectangle, and the two short sides of the second region are connected to the two short sides of the first region.

[0006] The present invention is further configured such that the second region and the first region form an angle α of 100 degrees to 170 degrees.

[0007] The present invention is further configured such that the width of the first region is the width of 8 weft yarns, and the width of the short side connecting the second region and the first region is the same as the width of the first region.

[0008] The present invention is further configured such that the fabric is woven with 78 warp yarns and 26 weft yarns to form a weave cycle, 29 warp yarns and 8 weft yarns to form the first region, and 10 warp yarns and 26 weft yarns to form the second region.

[0009] The present invention is further configured such that the base fabric area is a plain weave, the first area is a twill weave at an angle of 25 degrees to 60 degrees, and the second area is a twill weave at an angle of 50 degrees to 75 degrees.

[0010] The present invention is further configured such that the warp yarn of the fabric is made of 75D polyester filament and the weft yarn is made of 150D nylon high-elastic yarn.

[0011] In summary, this utility model has the following beneficial effects:

[0012] When the fabric is wet, the base fabric absorbs water and expands. The yarn interlacing angle in the second region is greater than that in the first region. Furthermore, the first region and the base fabric use the same warp yarns, while the second region and the base fabric use the same weft yarns. This provides space in the first region along the fabric length for the yarns in the base fabric to expand, and in the second region along the fabric width for the yarns in the base fabric to expand. When the fabric is dry, the second and first regions are higher than the base fabric. Therefore, through the height difference, the first region restrains the longitudinal shrinkage of the base fabric along the fabric length, and the second region restrains the lateral shrinkage of the base fabric along the fabric width. This prevents the base fabric from deforming, which could lead to cracking or deformation on the leather surface. Attached Figure Description

[0018] 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.

[0019] like Figure 1 — Figure 4 As shown, this embodiment discloses a fabric in which the warp yarns of the base fabric are made of 75D polyester filament and the weft yarns are made of 150D nylon high-elastic yarn. The fabric is formed by interlacing 78 warp yarns and 26 weft yarns in a loop to form a horizontal stripe area 1 and a base fabric area 2. Therefore, the base fabric includes a horizontal stripe area 1 and a base fabric area 2. A leather surface is provided above the horizontal stripe area 1 and the base fabric area 2 to form a leather fabric.

[0020] In one weave cycle, the 1st and 2nd weft yarns interweave with the 1st warp yarn and warp yarns 49-78 to form the horizontal stripe area 1; the 1st and 2nd weft yarns interweave with the 2nd to 48th warp yarns to form the base fabric area 2; the 3rd and 4th weft yarns interweave with the 1st to 2nd warp yarns and warp yarns 48-78 to form the horizontal stripe area 1; the 3rd and 4th weft yarns interweave with the 3rd to 47th warp yarns to form the base fabric area 2; and the 5th and 6th weft yarns interweave with the 1st to 3rd warp yarns... The 47th-78th weft yarns interweave to form horizontal stripe area 1; the 5th and 6th weft yarns interweave with the 4th-46th warp yarns to form base fabric area 2; the 7th and 8th weft yarns interweave with the 1st-4th warp yarns and the 46th-78th warp yarns to form horizontal stripe area 1; the 7th and 8th weft yarns interweave with the 5th-45th warp yarns to form base fabric area 2; the 9th and 10th warp yarns interweave with the 2nd-5th warp yarns and the 45th-48th warp yarns to form horizontal stripe area 1; the 9th and 10th weft yarns interweave with the 1st warp yarn, the 6th-44th warp yarns, and the 49th-78th warp yarns to form base fabric area 2; the 11th and 12th weft yarns interweave with the 3rd-6th warp yarns and the 44th-47th warp yarns to form horizontal stripe area 1 ...46th-78th warp yarns to form horizontal stripe area 1; the 11th and 12th weft yarns interweave with the 46th-78th warp yarns to form horizontal stripe area 1; the 11th and 12th weft yarns interweave The weft yarns interweave with warp yarns 1-2, 7-43, and 48-78 to form base fabric area 2; the weft yarns 13 and 14 interweave with warp yarns 4-7 and 43-46 to form horizontal stripe area 1; the weft yarns 13 and 14 interweave with warp yarns 1-3, 8-42, and 47-78 to form base fabric area 2; the weft yarns 15 and 16 interweave with warp yarns 5-8 and 42-45 to form horizontal stripe area 1; the weft yarns 15 and 16 interweave with warp yarns 1-4, 9-41, and 46-78 to form base fabric area 2; the weft yarns 17 and 18 interweave with warp yarns 6-9 and 41... —44 warp yarns interweave to form horizontal stripe area 1; weft yarns 17 and 18 interweave with warp yarns 1-5, 10-40, and 45-78 to form base fabric area 2; weft yarns 19 and 20 interweave with warp yarns 7-43 to form horizontal stripe area 1; weft yarns 19 and 20 interweave with warp yarns 1-6 and 44-78 to form base fabric area 2; weft yarns 21 and 22 interweave with warp yarns 8-42 to form horizontal stripe area 1; weft yarns 21 and 22 interweave with warp yarns 1-7 and 43-78 to form base fabric area 2; weft yarns 23 and 24 interweave with warp yarns 9-41 to form horizontal stripe area 1 ... The weft yarns interweave with warp yarns 1-8 and 42-78 to form base fabric zone 2. The 25th and 26th weft yarns interweave with warp yarns 10-40 to form stripe zone 1. The 25th and 26th weft yarns interweave with warp yarns 1-9 and 41-78 to form base fabric zone 2. Therefore, stripe zone 1 and base fabric zone 2 are arranged alternately and cyclically along the length of the fabric. Since base fabric zone 2 is a plain weave and stripe zone 1 is a twill weave, the alternating arrangement of stripe zone 1 and base fabric zone 2 creates mutual support and constraint between base fabric zone 2 and stripe zone 1, thus preventing excessive deformation of the yarns when they absorb moisture or dry.

[0021] In the warp and weft yarns that interweave to form horizontal stripe zone 1, warp yarns 1 and 49 interweave with weft yarns 1-8; warp yarns 2 and 48 interweave with weft yarns 3-10; warp yarns 3 and 47 interweave with weft yarns 5-12; warp yarns 4 and 46 interweave with weft yarns 7-14; warp yarns 5 and 45 interweave with weft yarns 9-16; warp yarns 6 and 44 interweave with weft yarns 11-18; warp yarns 7 and 43 interweave with weft yarns 13-20; warp yarns 8 and 42 interweave with weft yarns 15-22; warp yarns 9 and 41 interweave with weft yarns 17-24; and warp yarns 10 and 40 interweave with weft yarns 19-26 to form the second zone 12. Meanwhile, warp yarns 11-39 interweave with weft yarns 19-26, and warp yarns 50-78 interweave with weft yarns 1-8 to form the second zone 12. Region 11, because the second region 12 is centered on warp yarns 11-39 or 50-78, and the warp yarns of the second region 12 are symmetrically interwoven, therefore the horizontal stripe area 1 includes two symmetrically distributed second regions 12 and two first regions 11 connecting the second regions 12. In the weave cycle, the first regions 11 are interwoven in a matrix arrangement. In a horizontal stripe area 1, one of the two first regions 11 is located at the intersection of warp yarns 10-39 and weft yarns 19-26, and the other is located at the intersection of warp yarns 50-78 and weft yarns 1-8. Therefore, in the horizontal stripe area 1, adjacent two first regions 11 are arranged in a stepped pattern along the width of the fabric, and the first region 11 is rectangular, while the second region... In region 12, each warp yarn gradually interweaves with the weft yarn from the 1st to the 9th warp yarn with a position difference of two weft yarns. Simultaneously, in region 12, each warp yarn gradually interweaves with the weft yarn from the 40th to the 49th warp yarn with a position difference of two weft yarns. Therefore, region 12 is a parallelogram. In one weave cycle, the two short sides of region 12 are located at the 1st and 9th warp yarns and the 40th and 49th warp yarns, respectively. The warp yarns of region 11 are located adjacent to the warp yarns of region 12. Therefore, the two short sides of region 12 connect with the two short sides of region 11. Since the base fabric region 2 is a plain weave and region 11 is a 25-60 degree twill weave, preferably, region 12... Region 11 is a 45-degree twill weave, and region 12 is a 50-75 degree twill weave, preferably a 63-degree twill weave. Therefore, due to the plain weave structure, the yarn gaps in base fabric region 2 are minimized. The warp and weft yarn interlacing angle in region 12 is greater than that in region 11, resulting in an angle α of 100-170 degrees between region 12 and region 11, preferably α of 113 degrees. This makes the yarn gaps in region 12 larger than those in region 11, allowing for yarn expansion. Thus, when the fabric is wet, the yarn gaps along the fabric length...The first region 11 uses the same warp yarns as the base fabric region 2. Therefore, after the fabric absorbs moisture, the warp yarns in the base fabric region 2 expand, causing compression between the yarns. While the first region 11 itself experiences compression after absorbing moisture, its structure with floats prevents it from changing. This provides the first region 11 with some space for warp yarn slippage in the base fabric region 2, while simultaneously suppressing out-of-range deformation of the warp yarns in the base fabric region 2. Similarly, the second region 12, located in the fabric width direction, uses the same weft yarns as the base fabric region 2. Therefore, after the fabric absorbs moisture, the weft yarns in the base fabric region 2 expand, causing compression between the yarns. The second region 12 itself experiences compression after absorbing moisture, but its structure with floats prevents it from changing. This provides the second region 12 with some space for weft yarn slippage in the base fabric region 2, while simultaneously suppressing out-of-range deformation of the weft yarns in the base fabric region 2.

[0022] Because base fabric area 2 is a plain weave, first area 11 is a 2-up, 2-down 45-degree twill weave, and second area is a 2-up, 2-down 63-degree twill weave, the plain weave fabric, due to its shorter float length, makes first area 11 and second area 12 higher than base fabric area 2. Furthermore, in first area 11, 29 warp yarns interweave with 8 weft yarns, and the width of first area 11 is the width of 8 weft yarns. In second area 12, 10 warp yarns interweave with 26 weft yarns, and each warp yarn in second area 12 interweaves with 8 weft yarns. Therefore, the width of the short side connecting the second region 12 and the first region 11 is the same as the width of the first region 11, causing the yarns of the first region 11 and the second region 12 to be curved compared to the yarns of the base fabric region 2. This increases the interlacing path of the yarns in the first region 11 and the second region 12. Therefore, when the fabric is dry, the first region 11 and the base fabric region 2 use the same warp yarns along the length of the fabric. Thus, when the fabric is dry, the warp yarns of the base fabric region 2 shrink, but because of the... The increased interlacing path restricts the shrinkage of the warp yarns in the base fabric area 2 when the warp yarns shrink. Since the twill weave itself has some elastic recovery during its own drying shrinkage, the first area 11 remains unchanged, thus restricting the warp shrinkage of the base fabric area 2. Similarly, the second area 12, located in the fabric width direction, uses the same weft yarns as the base fabric area 2. Therefore, when the fabric dries, the weft yarns in the base fabric area 2 shrink. However, due to the increased interlacing path in the second area 12, the weft yarns in the second area 12 restrict the shrinkage of the weft yarns in the base fabric area 2 when the weft yarns shrink. Since the twill weave itself has some elastic recovery during its own drying shrinkage, the second area 12 remains unchanged, thus restricting the weft shrinkage of the base fabric area 2. This reduces the stress difference caused by uneven expansion and contraction in different areas of the fabric, preventing cracking and deformation of the leather surface due to base fabric deformation.
