Description

Technical Field

[0001] The present application relates to the technical field of textile processing, and in particular to a breathable elastic woven fabric and a preparation method thereof. Background Art

[0002] As a material that can provide excellent elasticity, elastic fiber is increasingly used in clothing fabrics. It can give the fabric good elasticity and resilience, making the clothing fit the human body curve better during wearing, reducing the sense of restraint and increasing the freedom of movement. Especially in sports, leisure and other scenes, people have higher and higher requirements for the elasticity of clothing. Highly elastic fabrics can not only provide the comfort and freedom required by the wearer, but also improve the durability and shape retention of clothing to a certain extent.

[0003] In order to improve the wearing comfort of clothing, the industry has tried to add elastic fibers such as spandex to the fabric to increase the elasticity of the fabric and enhance the comfort when wearing. However, these fabrics are not good in terms of breathability, and the wearer is prone to feeling stuffy and uncomfortable, especially when used in high temperature environments.

[0004] Although there are various attempts to improve the breathability of elastic fabrics, such as adding ventilation holes or using special textile structures, these methods often fail to effectively improve the overall breathability of the fabric while maintaining elasticity. Traditional fiber combinations and weaving processes limit the balance of these two key properties of the fabric, making the product often unable to meet the market's comprehensive demand for high-performance fabrics.

[0005] Therefore, it is necessary to provide a new breathable elastic woven fabric to meet the elasticity and breathability requirements of the fabric. Summary of the invention

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0029] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0030] As a material that can provide excellent elasticity, elastic fiber is increasingly used in clothing fabrics. It can give the fabric good elasticity and resilience, making the clothing fit the human body curve better during wearing, reducing the sense of restraint and increasing the freedom of movement. Especially in sports, leisure and other scenes, people have higher and higher requirements for the elasticity of clothing. Highly elastic fabrics can not only provide the comfort and freedom required by the wearer, but also improve the durability and shape retention of clothing to a certain extent.

[0031] In order to improve the wearing comfort of clothing, the industry has tried to add elastic fibers such as spandex to the fabric to increase the elasticity of the fabric and enhance the comfort when wearing. However, these fabrics are not good in terms of breathability, and the wearer is prone to feeling stuffy and uncomfortable, especially when used in high temperature environments.

[0032] Although there are various attempts to improve the breathability of elastic fabrics, such as adding ventilation holes or using special textile structures, these methods often fail to effectively improve the overall breathability of the fabric while maintaining elasticity. Traditional fiber combinations and weaving processes limit the balance of these two key properties of the fabric, making the product often unable to meet the market's comprehensive demand for high-performance fabrics.

[0033] Based on this, the inventor of the present application proposed a new breathable elastic woven fabric to meet the requirements for elasticity and breathability of the fabric.

[0034] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0035] Figure 1 This is a schematic diagram of the structure of the breathable elastic woven fabric provided in this application. Figure 1 As shown, the breathable elastic woven fabric provided in the embodiment of the present application is formed by staggered warp and weft arrangement of the first composite yarn 101 and the second yarn 102; the warp and weft arrangement of the first composite yarn 101 and the second yarn 102 is: 4:2, 6:2, 8:2 or 10:2.

[0036] The first composite yarn 101 is made of polyester and spandex, or the first composite yarn 101 is made of nylon and spandex; the second yarn 102 is spandex.

[0037] The first composite yarn 101 is composited by mechanically covering yarn or air covering yarn. The second yarn 102 is spandex fiber.

[0038] In one implementation, the first composite yarn 101 is made of polyester and spandex by mechanically covering the yarn, and the second yarn 102 is made of soluble yarn and spandex by mechanically covering the yarn. The first composite yarn 101 and the second yarn 102 are woven according to the warp and weft arrangement of 4:2, 6:2, 8:2 or 10:2 to ensure close bonding and uniform distribution between the yarns.

[0039] In one implementation, the first composite yarn 101 is made of nylon and spandex fibers by mechanically covering the yarn, and the second yarn 102 is spandex fibers. The first composite yarn 101 and the second yarn 102 are woven in a warp and weft arrangement of 4:2, 6:2, 8:2 or 10:2 to ensure close bonding and uniform distribution between the yarns.

[0040] In one implementation, the first composite yarn 101 is made of polyester and spandex by air-coated yarn, and the second yarn 102 is spandex fiber. The first composite yarn 101 and the second yarn 102 are woven according to a warp and weft arrangement of 4:2, 6:2, 8:2 or 10:2 to ensure close bonding and uniform distribution between the yarns.

[0041] In one implementation, the first composite yarn 101 is made of nylon and spandex by air-coating, and the second yarn 102 is made of soluble yarn and spandex by mechanically coating. The first composite yarn 101 and the second yarn 102 are woven in a warp and weft arrangement of 4:2, 6:2, 8:2 or 10:2 to ensure close bonding and uniform distribution between the yarns.

[0042] The fineness range of the first composite yarn is 25Dtex to 45Dtex, and the fineness range of the second yarn is 5Dtex to 10Dtex. The finished product weight of the breathable elastic woven fabric of this embodiment is 80g / m 2 ~100g / m 2 .

[0043] In a possible implementation, the spandex fiber in the first composite yarn 101 is a dyeable spandex fiber; and the second yarn 102 is a dyeable hot-melt spandex. Among them, the acid-dyable spandex has a good ability to absorb and fix dyes, and can achieve uniformity and depth control of dyeing, so that the fabric color is full, stable and durable. At the same time, the spandex fiber treated with acid dyeing has high color fastness, can maintain good color stability after daily use and multiple washings, and is not easy to fade or discolor. At the same time, hot-melt spandex can be bonded with other fiber materials in a hot-melt state to form a very strong bond, thereby improving the overall strength and durability of the fabric or composite material. At the same time, as a type of spandex, hot-melt spandex retains the excellent elastic properties of spandex, so that the fabric has excellent stretchability and resilience.

[0044] The breathable elastic woven fabric of this embodiment is formed by the first composite yarn 101 and the second yarn 102 being staggered according to the warp and weft arrangement; the warp and weft arrangement of the first composite yarn 101 and the second yarn 102 is: 4:2, 6:2, 8:2 or 10:2; wherein the first composite yarn 101 is made of polyester and spandex, or the first composite yarn 101 is made of nylon and spandex; the second yarn 102 is spandex fiber. After the soluble yarn is dissolved, the gaps where the first composite yarn 101 and the second yarn 102 are interwoven will be relatively large, making the fabric more breathable. At the same time, spandex can make the fabric have excellent stretchability and resilience. According to the present application, the dual requirements of the fabric for elasticity and breathability can be met.

[0045] Figure 2 The present invention provides a flow chart of the method for preparing the breathable elastic woven fabric. Figure 2 As shown, the method for preparing the breathable elastic woven fabric provided in this embodiment may include the following steps 2100 to 2300:

[0046] Step 2100: subjecting polyester and spandex to a first composite treatment, or subjecting nylon and spandex to a first composite treatment, to produce a first composite yarn.

[0047] Wherein, the first composite treatment is a mechanically coated yarn treatment or an air coated yarn treatment.

[0048] In this step, the first composite yarn can be made from polyester and spandex by mechanically covering the yarn, or the first composite yarn can be made from polyester and spandex by air covering the yarn, or the first composite yarn can be made from nylon and spandex by mechanically covering the yarn, or the first composite yarn can be made from nylon and spandex by air covering the yarn.

[0049] Step 2200: subjecting the soluble fiber to a second composite treatment with the spandex to obtain a second composite yarn.

[0050] Wherein, the second composite treatment is an air-covered yarn treatment.

[0051] It should be noted that this embodiment does not specifically limit the execution order of step 2100 and step 2200. For example, step 2100 may be executed first, and then step 2200; or, step 2200 may be executed first, and then step 2100; or, step 2100 and step 2200 may be executed simultaneously.

[0052] Step 2300: Weaving the first composite yarn and the second composite yarn to obtain a grey fabric.

[0053] In this step, the warp and weft arrangement of the first composite yarn and the second composite yarn is 4:2, 6:2, 8:2 or 10:2 to ensure close bonding and uniform distribution between the yarns.

[0054] Step 2400: Process the grey cloth to obtain the breathable elastic woven fabric.

[0055] Specifically, after weaving the grey fabric in step 2300, the grey fabric is pretreated, and the pretreatment includes at least preshrinkage and desizing; then the soluble yarn in the pretreated grey fabric is dissolved to obtain the breathable elastic woven fabric. After the soluble yarn is dissolved, the gaps where the first composite yarn and the second composite yarn are interwoven will be larger, so that the fabric has better air permeability.

[0056] The preparation method of the breathable elastic woven fabric of this embodiment is to prepare the first composite yarn by subjecting polyester and spandex to a first composite treatment, or subjecting nylon and the spandex to the first composite treatment; and preparing the second composite yarn by subjecting the easily soluble yarn and the spandex to a second composite treatment. Then, the first composite yarn and the second composite yarn are woven according to the warp and weft arrangement to obtain a grey cloth; wherein the warp and weft arrangement of the first composite yarn and the second composite yarn is: 4:2, 6:2, 8:2 or 10:2; and the grey cloth is treated to obtain the breathable elastic woven fabric. According to the present application, after the easily soluble yarn is dissolved, the gaps where the first composite yarn and the second composite yarn are interwoven will be relatively large, so that the fabric has better air permeability, and at the same time, spandex can make the fabric have excellent stretchability and resilience. Therefore, the breathable elastic woven fabric worthy of the method of the present application can meet the dual requirements of the fabric for elasticity and air permeability.
