Description

Technical Field

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

[0002] Existing technologies often enhance tear resistance through composite layer structures, but multi-layer structures not only sacrifice the breathability and softness of the fabric, but also make the fabric too heavy. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tear-resistant fabric. This fabric is formed by interlacing warp and weft yarns to create a first longitudinal stripe and a second longitudinal stripe, resulting in a single-layer fabric that reduces its bulkiness. The first longitudinal stripe includes a first region and a second region, and the second region further includes a first unit and a second unit. The first region and the second longitudinal stripe employ a tightly interlaced structure to increase the fabric's strength. The first region, the first unit, and the second unit utilize different structural designs to create a textured surface. The floating yarn structure in the three regions allows air to pass through the gaps between fibers, increasing the fabric's breathability. Furthermore, the floating yarn structure reduces yarn interlacing, increasing the fabric's tensile strength. The symmetrical and staggered distribution of the first and second units creates discontinuous stress dispersion points in the first unit, thereby reducing the fabric's tearing tendency.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a tear-resistant fabric, characterized in that it comprises a first longitudinal strip and a second longitudinal strip arranged alternately and cyclically along the width of the fabric. Each first longitudinal strip includes a first region and a second region symmetrically distributed about the first region as an axis of symmetry. Each second region includes a first unit and a second unit, and the first unit and the second unit...

[0005] The present invention is further configured such that, in each of the first vertical bars, the width of the first region located between two second units is greater than the width of the first region located between two first units.

[0006] The present invention is further configured such that two second regions are grouped together, and two adjacent groups of second regions are arranged obliquely.

[0007] The present invention is further configured such that the first region is lower than the second unit, the second unit is lower than the first unit, and the second vertical bar has the same height as the first region.

[0008] The present invention is further configured such that, in a group of two second regions, the middle position of the second unit in one of the two adjacent groups is opposite to the first unit in the other group.

[0009] The present invention is further configured such that, located in the second region, the length of the first unit is one-fifth of that of the second unit.

[0010] The present invention is further configured such that the fabric has a weave cycle of 72 warp yarns and 72 weft yarns, 24 warp yarns and 72 weft yarns interlacing to form the first longitudinal stripe, and 12 warp yarns and 72 weft yarns interlacing to form the second longitudinal stripe.

[0011] The present invention is further configured such that warp yarns 1-24 interweave with weft yarns 1-72 to form the first longitudinal strip, warp yarns 25-36 interweave with weft yarns 1-72 to form the second longitudinal strip, warp yarns 37-60 interweave with weft yarns 1-72 to form the first longitudinal strip, and warp yarns 61-72 interweave with weft yarns 1-72 to form the second longitudinal strip.

[0012] In summary, this utility model has the following beneficial effects:

[0013] The single-layer fabric is formed by interlacing warp and weft yarns, reducing the fabric's heaviness. The single-layer fabric includes a first longitudinal strip and a second longitudinal strip. The first longitudinal strip includes a first region and a second region. The second region includes a first unit and a second unit. The tight interlacing of fibers in the first region and the second longitudinal strip increases the fabric's strength. The symmetrical staggered distribution of the first and second units and the float structure create discontinuous stress dispersion points in the fabric, thereby reducing tearing. At the same time, the float structure prevents the fibers from interlacing, thus forming pores. This not only allows air to exchange between the inside and outside of the fabric, improving its breathability, but also increases its stretchability. 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 3As shown, this embodiment discloses a tear-resistant fabric. The fabric has a weave cycle of 72 warp yarns and 72 weft yarns. In one weave cycle, warp yarns 1-24 interweave with weft yarns 1-72 to form a first longitudinal stripe 100, warp yarns 25-36 interweave with weft yarns 1-72 to form a second longitudinal stripe 200, warp yarns 37-60 interweave with weft yarns 1-72 to form the first longitudinal stripe 100, and warp yarns 61-72 interweave with weft yarns 1-72 to form the second longitudinal stripe 200. Therefore, in one weave cycle, 24 warp yarns and 72 weft yarns interweave to form the first longitudinal stripe 100, and 12 warp yarns and 72 weft yarns interweave to form the second longitudinal stripe 200. Thus, after the fabric is formed, it includes a first longitudinal stripe arranged alternately along the fabric width direction. The first longitudinal stripe 100 and the second longitudinal stripe 200 are located within the first longitudinal stripe 100 formed by the interweaving of warp yarns 1-24 and weft yarns 1-72. Within the range of weft yarns 1-30 and 37-66, warp yarns 7-18 interweave with weft yarns to form the first region 101. Within the range of weft yarns 31-36 and 67-72, warp yarns 9-16 interweave with weft yarns to form the first region 101. The remaining warp and weft yarns interweave to form the second region 102, located within the first longitudinal stripe 100 formed by the interweaving of warp yarns 37-60 and weft yarns 1-72. Within the range of weft yarns 1-12, 19-48, and 55-72, warp yarns 43-54 interweave with weft yarns to form the first region 101. Warp yarns 13-18 interweave with weft yarns 49-54... Within the 4-weft yarn range, warp yarns 45-52 interweave with weft yarns to form the first region 101, and the remaining warp and weft yarns interweave to form the second region 102. Within the range of warp yarns 1-24 and weft yarns 1-72, forming the first longitudinal stripe 100; within the range of weft yarns 1-30 and 37-66, warp yarns 1-6 and 19-24 interweave with weft yarns to form the second unit 1012; within the range of weft yarns 31-36 and 67-72, warp yarns 1-8 and 17-24 interweave to form the first unit 1011; within the range of warp yarns 37-60 and 1-72, forming the first longitudinal stripe 100; and within the range of weft yarns 1-12, 19-48, and 55-72, warp yarns 37-... The 42nd warp yarn, the 55th-60th warp yarn, and the weft yarn interweave to form the second unit 1012. Within the range of the 13th-18th and 49th-54th weft yarns, the 37th-44th warp yarn, the 53rd-60th warp yarn, and the weft yarn interweave to form the first unit 1011. Because the interweaving position of the warp and weft yarns in the first region 100 is located in the middle of the second region 102, and with the interweaving position of the warp and weft yarns in the first region 100 as the axis of symmetry, each first longitudinal strip 100 includes a first region 101 and a second region 102 symmetrically distributed with the first region 101 as the axis of symmetry. Each second region 102 includes a first unit 1011 and a second unit 1012. The first unit 1011 and the second unit 1012 are arranged alternately along the length of the fabric.The first region 101 and the second vertical stripe 200 adopt a 1-up-1-down weave structure. The first unit 1011 uses a full warp float weave, with the float length being 8 warp weave points. The second unit 1012 uses a five-end, two-fly warp satin weave structure, with the longest float length being 4 warp weave points. Therefore, the float structure of the first unit 1011 is larger than that of the second unit 1012, and the float structure of the second unit 1012 is larger than that of the first region 101 and the second vertical stripe 200. This interweaving of the float structures of the first unit 1011 and the second unit 1012 between the first region 101 and the second vertical stripe 200 ensures that, when the fabric is stretched, the floats do not interweave, allowing the fibers to maintain their original shape. This gives the fabric a certain degree of stretch and prevents deformation, thus increasing its resistance to deformation and making it less prone to tearing. Furthermore, because the float length of the first unit 1011 is the longest, and the difference in float length between the first unit 1011 and the second unit 1012 is significant... With four warp points, the float length between the second unit 1012 and the first region 101 and the second warp stripe 200 differs by three warp points. However, the number of warp and weft yarn interlacing threads in the first region 101 and the second warp stripe 200 is greater than that in the second unit 1012, and the number of warp and weft yarn interlacing threads in the second unit 1012 is greater than that in the first unit 1011. Therefore, when the fabric is stretched, the float structure provides a certain tensile force while limiting the float length, reducing the possibility of breakage due to excessive stretching. Simultaneously, because the float length prevents fiber interlacing, the fibers remain tightly packed, resulting in greater airflow between fibers in the first unit 1011 than in the second unit 1012, and greater airflow between fibers in the second unit 1012 than in the first region 101 and the second warp stripe 200. This allows air exchange through multiple units, increasing the fabric's breathability.

[0020] Because in the first longitudinal stripe 100 formed by the interweaving of warp yarns 1-24 and weft yarns 1-72, within the range of weft yarns 1-30 and 37-66, 12 warp yarns and 60 weft yarns interweave to form the first region 101; within the range of weft yarns 31-36 and 67-72, 8 warp yarns and 12 weft yarns interweave to form the first region 101; similarly, in the first longitudinal stripe 100 formed by the interweaving of warp yarns 37-60 and weft yarns 1-72, within the range of weft yarns 1-12, 19-48, and 55-72, 12 warp yarns and 60 weft yarns interweave to form the first region 101; and within the range of weft yarns 13-18 and 49-54, 8 warp yarns and 12 weft yarns interweave to form the first region 101, therefore, in each first... In the longitudinal stripe 100, the number of interlaced yarns in the first region 101 between two second units 1012 is greater than the number of interlaced yarns in the first region 101 between two first units 1011. Consequently, the width of the first region 101 between two second units 1012 is greater than the width of the first region 101 between two first units 1011. The second longitudinal stripe 200 is formed by 12 warp yarns and 72 weft yarns interlacing together. The first region 101 and the second longitudinal stripe 200 have a 1-up-1-down weave structure, which makes the fiber interlacing of the first region 101 and the second longitudinal stripe 200 relatively tight. The first region 101 and the second longitudinal stripe 200 have the most interlaced yarns, thus increasing the strength of the fabric and making it less prone to tearing.

[0021] In one weave cycle, in the first warp 100 formed by the interlacing of warp yarns 1-24 and weft yarns 1-72, the first unit 1011 is located at warp yarns 1-8, warp yarns 17-24, and weft yarns 31-36 and 67-72. Similarly, in the first warp 100 formed by the interlacing of warp yarns 37-60 and weft yarns 1-72, the first unit 1011 is located at warp yarns 37-44, warp yarns 53-60, and weft yarns 13-18 and 49-54. Likewise, in the first warp 100 formed by the interlacing of warp yarns 1-24 and weft yarns 1-72, the second unit 1012 is located at... The first unit 1012 is located at the intersection of warp yarns 1-6, warp yarns 19-24, and weft yarns 1-30 and 37-66, and is situated within the first longitudinal stripe 100 formed by the interweaving of warp yarns 37-60 and weft yarns 1-72. The second unit 1012 is located at the intersection of weft yarns 1-12, weft yarns 19-48, and weft yarns 55-72, and is therefore situated within the first longitudinal stripe 100 formed by the interweaving of warp yarns 1-24 and weft yarns 1-72. The first unit 1011 is formed by the interweaving of warp yarns 1-8 and weft yarns 31-36 and 67-72, and the second unit 1012 is formed by the interweaving of warp yarns 1-6 and weft yarns 1-30 and 37-66. The second region 102 is defined as follows: two second regions 102 are grouped together. The second region 102 formed by the interlacing of warp yarns 1-24 and weft yarns 1-72 is opposite to the second region 102 formed by the interlacing of warp yarns 37-60 and weft yarns 1-72. Similarly, the first unit 1011 within the interlacing range of warp yarns 1-24 and weft yarns 1-72 is opposite to the second unit 1012 within the interlacing range of warp yarns 37-60 and weft yarns 1-72. Because the first unit 1011 has a length of 6 weft yarns and the second unit 1012 has a length of 30 weft yarns, the first unit within the second region 102... The length of 1011 is one-fifth of that of the second unit 1012. Therefore, the two adjacent groups of second regions 102 are arranged diagonally. In a group of two second regions 102, the middle position of the second unit 1012 in one of the two adjacent groups is opposite to the first unit 1011 in the other group. Since the float length of the first unit 1011 is greater than that of the second unit 1012, and the float length of the second unit 1012 is greater than that of the first region 101 and the second longitudinal strip 200, the first unit 1011 and the second unit 1012 form discontinuous stress dispersion points in the weave cycle, thereby reducing tearing when the fabric is stretched.

[0022] Because the first region 101 and the second longitudinal strip 200 have the same weave structure, and the first unit 1011 is a float with 8 weave points and the second unit 1012 is a float with 4 weave points, the floats are higher than the weave points due to the tightness between the fibers during weave. Therefore, the first region 101 is lower than the second unit 1012, and the second unit 1012 is lower than the first unit 1011. The second longitudinal strip 200 is at the same height as the first region 101, thus creating a textured surface on the fabric. Since the fabric is a single-layer structure, it reduces the feeling of heaviness and increases breathability. At the same time, the textured structure reduces the amount of fabric in contact with other fabrics, further increasing breathability. Also, the textured structure provides some cushioning when the fabric is stretched. And because the floats are higher than the weave points, when the fabric is stretched, there is a constraint between the floats and the weave points, reducing the breakage of the floats and the fiber breakage between the weave points, thereby reducing the fabric's tear resistance.
