A textured stretch fabric

Abstract

This utility model relates to the field of textile fabric technology, specifically to a textured elastic fabric, which is woven from warp yarns, a first weft yarn, and a second weft yarn. The spandex denier of the second weft yarn is higher than that of the first weft yarn. The interweaving of the warp yarns with the first weft yarn forms a first section, and the interweaving of the warp yarns with the second weft yarn forms a second section. The first and second sections alternate in the warp direction, and the reed insertion quantity of the warp yarns changes periodically in the warp direction according to a repeating ratio. In this utility model, the alternation of the first and second sections in one cycle creates a rhythmic, slightly wrinkled texture during processing, with the warp yarns of the first section raised and the warp yarns of the second section recessed. Simultaneously, the periodic change in the reed insertion quantity of the warp yarns in the warp direction amplifies the warp-directional differences, thereby creating a three-dimensional, crisscrossing effect on the fabric surface.

Description

Technical Field

[0001] This utility model relates to the field of textile fabric technology, specifically to a textured elastic fabric. Background Technology

[0002] With the rise of urban light sports and micro-vacations, the emphasis on skin protection and healthy lifestyles has also driven the rapid development of the functional sun protection clothing market. At the same time, consumers have put forward higher requirements for the appearance of clothing when switching between multiple scenarios such as "commuting, leisure and short outdoor trips". Consumers not only pursue lightweight and portable, but also hope that the clothing has a three-dimensional texture and lasting elasticity.

[0003] Traditional plain-weave sun protection fabrics have a flat surface and lack three-dimensional layers, making it difficult to present rich textures in a relaxed cut. The pleats obtained by finishing pleating or chemical wrinkling are prone to collapse and failure after repeated washing and wearing, making it difficult to meet the requirements of easy care and long-lasting style, and also increasing the process and weight.

[0004] Therefore, in order to achieve the dual requirements of "lightweight and textured", a stable, controllable and rhythmic micro-wrinkled texture is directly formed by controlling the elasticity of the yarn itself and the arrangement parameters during the weaving stage. This can achieve both sun protection performance and fashion expression without adding finishing processes. Utility Model Content

[0005] The purpose of this invention is to provide a textured elastic fabric with a rhythmic, slightly wrinkled texture.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A textured elastic fabric is made of warp yarns, a first weft yarn, and a second weft yarn, wherein the spandex denier of the second weft yarn is higher than that of the first weft yarn. The warp yarns interweave with the first weft yarn to form a first section, and the warp yarns interweave with the second weft yarn to form a second section. The first section and the second section alternate in the warp direction, and the number of reeds inserted into the warp yarns changes periodically in the warp direction according to a repeating ratio.

[0008] Preferably, the warp yarn is made of nylon-spandex coated yarn.

[0009] Preferably, the core yarn of the warp yarn is spandex and the outer fiber is low denier nylon FDY filament.

[0010] Preferably, the first weft yarn is a nylon-spandex covered yarn, and the second weft yarn is a double weft yarn composed of two nylon-spandex covered yarns woven into the same shed.

[0011] Preferably, in the recurring unit of the fabric, the first weft yarn and the second weft yarn are introduced alternately in a recurring ratio, and in one recurring unit, along the warp direction, they are sequentially the first first section, the first second section, the second first section, and the second second section.

[0012] Preferably, the fabric has a 22x34 repeat unit, with the first weft yarn and the second weft yarn introduced alternately in a repeat ratio of 15:2, and the first first section, the first second section, the second first section, and the second second section are all plain weave.

[0013] Preferably, taking the first warp yarn in a cycle unit as an example, in the first first section A, the starting point is the warp weft ...

[0014] Preferably, the reed insertion of the warp yarn adopts a "3 yarns / insertion × 4 cycles + 5 yarns / insertion × 2 cycles" method, and the cycle ratio is 12:10.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This novel textured elastic fabric is made of warp yarns, a first weft yarn, and a second weft yarn. The spandex denier of the second weft yarn is higher than that of the first weft yarn. The first weft yarn interweaves with the warp yarn to form the first section, and the second weft yarn interweaves with the warp yarn to form the second section. In one cycle, the first and second sections alternate, resulting in a rhythmic, slightly wrinkled texture where the warp yarns in the first section are raised and the warp yarns in the second section are recessed. At the same time, the number of reeds inserted into the warp direction changes periodically in the warp direction according to the cycle ratio, amplifying the warp difference and thus creating a three-dimensional effect with interlacing warp and weft yarns on the fabric surface. Attached Figure Description

[0017] Figure 1 This is a pattern drawing of the textured elastic fabric of this utility model.

[0018] Figure 2 This is a schematic diagram of a loop unit structure of the textured elastic fabric of this utility model. Detailed Implementation

[0019] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0020] like Figures 1-2As shown, this embodiment provides a textured elastic fabric, which is formed by interlacing warp yarn 1 with first weft yarn 22 and second weft yarn 21 in a plain weave pattern. Warp yarn 1 is a nylon-spandex covered yarn with a core of 20D spandex and an outer layer of 12D low-denier nylon FDY filament; first weft yarn 22 is a nylon-spandex covered yarn with a core of 20D spandex and an outer layer of 12D low-denier nylon FDY filament; second weft yarn 21 is a double weft yarn composed of two nylon-spandex covered yarns identical to the first weft yarn woven into the same shed, thus making the spandex denier of the second weft yarn 21 higher than that of the first weft yarn 22.

[0021] In this embodiment, the fabric's repeating unit is 22 x 34, meaning 22 warp yarns and 34 weft yarns. The first weft yarn 22 and the second weft yarn 21 are introduced alternately in a 15:2 repeating ratio. In the repeating unit, the area where the first weft yarn 22 interweaves with the warp yarn 1 is designated as the first section A, and the area where the second weft yarn 21 interweaves with the warp yarn 1 is designated as the second section B. There are two first sections A and two second sections B in one repeating unit. The first sections A and second sections B alternate along the warp direction, and the warp and weft yarns move in a one-up-one-down relationship within each first section A and second section B.

[0022] like Figure 1 As shown, the two first sections A in the same cycle unit are defined as the first first section A and the second first section A, respectively, and the two second sections B are defined as the first second section B and the second second section B, respectively. Taking the first warp yarn 1 in a cycle unit as an example, in the first first section A, the starting point is the warp weft point and it cycles 7.5 times in a one-up-one-down pattern. In the first second section B, the starting point is the weft weft point and it cycles 1 time in a one-down-one-up pattern. In the second first section A, the starting point is the weft weft point and it cycles 7.5 times in a one-down-one-up pattern. In the second second section B, the starting point is the warp weft point and it cycles 1 time in a one-up-one-down pattern.

[0023] Because the second weft yarn 21 denier of the second section B is concentrated and has a large shrinkage, the warp yarn 1 is tightened and concave; while the first weft yarn 22 denier of the first section A is lower and has a smaller shrinkage, the warp yarn 1 float is longer and relatively convex, thus forming a texture effect of 0.15mm-0.20mm on the fabric surface.

[0024] like Figure 2 As shown, in order to give the fabric surface a strong three-dimensional feel, the warp yarn 1 is inserted using "3 yarns / insertion × 4 cycles (G1) + 5 yarns / insertion × 2 cycles (G2)", with a cycle ratio of 6:5, so that the warp tension changes periodically.

[0025] In conjunction with the warp reed entry and weft insertion cycles, using a warp yarn draft ratio of 4.0:weft yarn draft ratio of 3.0:3.5, after shrinking off the machine, the area using "3 threads / entry × 4 cycles (G1)" will show a three-dimensional vertical stripe effect with warp yarns and weft yarns alternating as the main body; the area using "5 threads / entry × 2 cycles (G2)" will show a near 1:1 interlacing effect of warp yarns and weft yarns, further amplifying the warp difference and making the fabric surface have a three-dimensional effect of crisscrossing.

[0026] After being dipped, rolled, dried, and shaped, the setting temperature is below the elasticity loss threshold of spandex, thus preserving the micro-wrinkled shape.

[0027] Through the synergy of the aforementioned yarn denier, draft ratio, and warp and weft cycle parameters, the fabric surface achieves a stable, controllable, and rhythmic micro-wrinkled texture during weaving and tension release, maintaining its appearance without additional finishing.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this invention. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.

All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
