Description

Technical Field

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

[0002] Lightweight chiffon fabrics are often made with a low-density plain weave structure. This low-density plain weave structure makes the fabric structure loose and the cohesion between yarns relatively weak, which makes the yarns prone to slippage and thus the fabric deformation. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a chiffon fabric in which the first longitudinal strip is at the same height as the first region, and the first longitudinal strip and the first region are higher than the second region. This height difference causes the weft yarns of the first longitudinal strip to interweave and bend, and all the warp yarns of the first region to interweave and bend, thereby increasing the cohesion between the yarns and restricting the slippage of yarns in adjacent regions. The yarn twist of the second region is higher than that of the yarns of the first longitudinal strip and the first region, thus forming a deformation zone in the second region. When the fabric is subjected to external force, the second region can change with the stretching of the fabric, thereby reducing the tensile stress of the first region and the first longitudinal strip, and thus reducing the overall deformation of the fabric.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a chiffon fabric, comprising a first longitudinal strip and a second longitudinal strip arranged alternately along the fabric width direction, the second longitudinal strip comprising a first region and a second region arranged alternately along the fabric length direction, under normal conditions, the length L1 of the second region is 0.5 times the length L2 of the first region, under warp stretching, the length L3 of the second region is 1.5 times the length L2 of the first region, and under weft stretching, the width of the second region is greater than the width of the first region.

[0005] The present invention is further configured such that the first region is at the same height as the first vertical strip, and the first region is higher than the second region.

[0006] The present invention is further configured such that the thickness of the second region under tension is thinner than the thickness of the second region under normal conditions.

[0007] The present invention is further configured such that the yarn twist in the second region is higher than the weft yarn twist in the first region, the yarn twist in the second region is higher than the warp yarn twist in the first longitudinal strip, and the weft yarn twist in the first region is the same as the warp yarn twist in the first longitudinal strip.

[0008] The present invention is further configured such that the yarn twist coefficient of the second region is 1300T / m, and the weft yarn and the warp yarn twist coefficient of the first longitudinal strip in the first region are 700T / m.

[0009] The present invention is further configured such that the fabric has a weave cycle of 20 warp yarns and 36 weft yarns, with 8 warp yarns and 36 weft yarns interwoven to form the first longitudinal stripe, and 12 warp yarns and 36 weft yarns interwoven to form the second longitudinal stripe.

[0010] The present invention is further configured such that 12 warp yarns and 12 weft yarns interweave to form the second region, and 12 warp yarns and 24 weft yarns interweave to form the first region.

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

[0012] The first longitudinal strip is at the same height as the first region, while the first longitudinal strip and the first region are higher than the second region. Due to the height difference, the weft yarns of the first longitudinal strip interweave and bend, and due to the height difference, all the warp yarns of the first region interweave and bend. This increases the cohesion between the yarns and restricts the slippage of yarns in adjacent regions. The second region forms a deformation zone through yarn twist. When the fabric is subjected to external force, the second region can absorb more tensile deformation, thereby reducing the tensile stress on the first region and the first longitudinal strip, thus reducing the deformation of the main structure of the fabric.

[0023] 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.

[0024] like Figure 1 — Figure 9 As shown, this embodiment discloses a chiffon fabric. The fabric is woven with a conventional warp density of 38 yarns / cm and a weft density of 38 yarns / cm. It is also woven with a low density. The fabric has a weave cycle of 20 warp yarns and 36 weft yarns. The 1st to 8th warp yarns and the 1st to 36th weft yarns interweave to form the first warp stripe 1. Therefore, in one weave cycle, 8 warp yarns and 36 weft yarns interweave to form the first warp stripe 1, and the 9th to 20th warp yarns and the 1st to 36th weft yarns interweave to form the second warp stripe 2. Therefore, in one weave cycle... In the weaving cycle, 12 warp yarns and 36 weft yarns interweave to form the second longitudinal stripe 2. Because the first longitudinal stripe 1 and the second longitudinal stripe 2 are formed by interweaving the same weft yarns with different warp yarns, the fabric includes the first longitudinal stripe 1 and the second longitudinal stripe 2 arranged alternately along the fabric width. The warp and weft yarns of the fabric are both made of 20D+20D polyester composite yarn, with a warp density of 480 yarns / 10cm and a weft density of 380 yarns / 10cm. It is woven by a water jet loom, which makes the chiffon fabric soft and light.

[0025] Within the interlacing range of the second longitudinal stripe 2, warp yarns 9-20 interlac with weft yarns 1-12 to form a second region 22. Therefore, 12 warp yarns interlac with 12 weft yarns to form the second region 22. Warp yarns 9-20 interlac with weft yarns 13-36 to form a first region 21. Therefore, 12 warp yarns interlac with 24 weft yarns to form the first region 21. Both the first region 21 and the second region 22 are formed by interlacing the same warp yarns with different weft yarns. Therefore, the second longitudinal stripe 2 includes alternating first regions 21 and second regions 22 along the fabric length direction. The first region 21 is formed by interlacing... Within the interlacing range of warp yarns 9-20 and weft yarns 13-36, warp yarns 9, 10, 14, 15, 19, and 20 interlace with weft yarns 13-36 in a plain weave, while warp yarns 11, 12, 13, 16, 17, and 18 interlace with weft yarns 13-36 in a 3-up-1-down pattern. Within the interlacing range of warp yarns 1-8 and weft yarns 1-36 forming the first longitudinal strip 1, warp yarns 4 and 5 interlace with weft yarns 1-36 in a plain weave, while warp yarns 1, 2, 3, 6, 7, and 8 interlace with weft yarns 1-36 in a 3-up-1-down pattern. The interlacing of warp yarns 9-20 and weft yarns forming the second region 22... Within the interlacing range of weft yarns 1-12, warp yarns 9-20 interlac with weft yarns 1-12 in a double-warp, single-weft pattern. Because the first region 21 has the same structure as the first longitudinal strip 1, and the float length of the first region 21 and the first longitudinal strip 1 is greater than the float length of the second region 22, and the first region 21 and the first longitudinal strip 1 are at the same height, with the first region 21 being higher than the second region 22, when the first longitudinal strip 1 is connected to the second region 22 through the height difference, the weft yarn portion of the first longitudinal strip 1 in the fabric width direction is curved due to the concave-convex interlacing. Similarly, the first region 21 is connected to the second region 22 through the height difference. At that time, all the warp yarns in the first region 21 along the fabric length direction are bent due to the concave-convex interlacing. Therefore, the height difference between the second region 22 and the first region 21 and the first longitudinal strip 1 increases the contact area between the first longitudinal strip 1 and the second longitudinal strip 2, as well as within the second longitudinal strip 2 itself, at the connection and interlacing point of the second region 22 and the first region 21 and the first longitudinal strip 1. The concave-convex structure causes the yarn to bend, increasing the interlacing surface area, thereby making the yarns at the connection point of the second region 22 and the first region 21 and the first longitudinal strip 1 mutually restrict each other, thus preventing the yarns in adjacent regions from slipping.

[0026] When the first longitudinal strip 1 is connected to the first region 21, the weft yarn portion of the first longitudinal strip 1 in the fabric width direction is straight due to equal-height interlacing, and all the warp yarns of the first longitudinal strip 1 in the fabric length direction are straight. When the first region 21 is connected to the first longitudinal strip 1, all the weft yarns of the first region 21 in the fabric width direction are straight due to equal-height interlacing. Because the straight yarns will slip due to low density, the yarn twist of the second region 22 is higher than the weft twist of the first region 21, and the yarn twist of the second region 22 is higher than the warp twist of the first longitudinal strip 1. Twist: The weft twist of the first region 21 is the same as the warp twist of the first warp strip 1. The twist coefficient of the yarn in the second region 22 is 1300T / m, while the twist coefficient of the weft yarn in the first region 21 and the warp yarn in the first warp strip 1 is 700T / m. Both the warp and weft yarns in the second region 22 use high-twist yarns. High twist results in a higher degree of fiber inclination, increasing friction between fibers and effectively storing elastic potential energy. When external force is applied, the change in the inclination angle of the yarn fibers generates a restoring force, thereby increasing the elasticity of the second region 22. Therefore, under normal conditions, because the twist coefficient of the second region 22 is 1... The first region 21 is formed by interlacing 2 warp yarns and 12 weft yarns, while the second region 22 is formed by interlacing 12 warp yarns and 24 weft yarns. Therefore, the length L1 of the second region 22 is 0.5 times the length L2 of the first region 21. Under warp stretching, due to the elasticity caused by the high twist of the second region 22, the length L3 of the second region 22 is 1.5 times the length L2 of the first region 21. Similarly, under weft stretching, the width of the second region 22 is greater than the width of the first region 21. Since the number and density of yarns in the second region 22 remain constant, when the second region... When stretched 22 times, the thickness of the second region 22 under stretched conditions is thinner than that under normal conditions. This results in a greater height difference between the first longitudinal strip 1 and the second region 22 in the weft direction, and a greater height difference between the first region 21 and the second region in the warp direction. Consequently, when the first longitudinal strip 1 and the first region 21 are stretched, the yarns between the first longitudinal strip 1, the first region 21, and the second region 22 become more curved, thereby increasing the cohesion between the yarns and thus increasing the restriction on yarn slippage in adjacent regions. This prevents the fabric from deforming under external force.

[0027] Because the warp and weft yarns of the second region 22 are high-twist yarns, and the second region 22 uses the same weft yarn as the first warp strip 1, the weft yarn of the first warp strip 1 is high-twist yarn, and the warp yarn of the first warp strip 1 is low-twist yarn. This increases the frictional resistance between the yarns at the intersection of the high-twist weft yarn and the low-twist warp yarn, making it difficult for the low-twist warp yarn to slip along its length, thus increasing the structural stability of the first warp strip 1. Similarly, because the second region 22 uses the same warp yarn as the first region 21, the warp yarn of the first region 21 is high-twist yarn, and the weft yarn of the first region 21 is low-twist yarn. This increases the frictional resistance between the yarns at the intersection of the high-twist warp yarn and the low-twist weft yarn, making it difficult for the low-twist weft yarn to slip along its width, thus increasing the structural stability of the first region 21. At the same time, because both the warp and weft yarns of the second region 22 are high-twist yarns... Therefore, when the fabric is subjected to external force, the second region 22 will change with the external force, and the warp yarns of the first region 21 and the weft yarns of the first longitudinal strip 1 will also change with the external force. Therefore, the elastic recovery force of the high-twist yarn in the second region 22 allows the second region 22 to return to its original state. The warp yarns of the first region 21 are high-twist yarns with elastic recovery force, so the intersection of the warp and weft yarns in the first region 21 will bring the low-twist weft yarns back to their original intersection position, thus restoring the first region 21 to its original state. Similarly, the weft yarns of the first longitudinal strip 1 are high-twist yarns with elastic recovery force, so the intersection of the weft yarns of the first longitudinal strip 1 and the warp yarns will bring the low-twist warp yarns back to their original intersection position, thus restoring the first longitudinal strip 1 to its original state. Since the second region 22 has the strongest tensile strength, it reduces the tensile stress of the first region 21 and the first longitudinal strip 1, thereby reducing the overall fabric deformation.
