[0002] Gauze fabric, due to its breathability and softness, is widely used in clothing, medical care, and other fields. However, existing conventional gauze fabrics have significant technical defects:

[0003] 1. Lack of elasticity: Conventional gauze is mostly machine-woven or simple warp-knitted, which cannot conform to the curves of the human body when worn or used, restricting movement, and is especially unsuitable for clothing scenarios that require dynamic fit;

[0004] 2. Poor dimensional stability: Cotton material itself has a large shrinkage rate, and the structure of regular gauze is loose. It is easy to deform and shrink after washing. After repeated use, the dimensional deviation is obvious, which affects its practicality.

[0005] 3. Easy to shed threads and insufficient stiffness: The loop structure of the existing gauze is unstable, the edges are prone to fraying and shedding threads, and the fabric has poor drape, lacks shape when worn as outerwear, and is difficult to care for as clothing fabric;

[0006] 4. Insufficient moisture absorption and quick-drying performance: Although some gauze is breathable, moisture tends to remain inside the fabric after absorbing moisture, resulting in slow drying speed and insufficient wearing comfort. Utility Model Content

[0035] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0036] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0037] Traditional gauze fabrics are mostly woven from pure cotton. While they offer good breathability, they suffer from insufficient elasticity, poor dimensional stability, a tendency to shed threads, shrinkage after washing, and a lack of crispness, making them unsuitable for the comfort, aesthetics, and easy-wearing requirements of modern clothing. Especially when used for outerwear, traditional gauze fabrics lack resilience and are prone to wrinkling, affecting the wearing experience. Therefore, there is an urgent need to develop a warp-knitted fabric that retains the comfort of cotton while also possessing good elasticity and dimensional stability.

[0038] Example 1:

[0039] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4This embodiment discloses a cotton elastic warp-knitted fabric, including a fabric body woven from combs GB1, GB2 and GB3. Comb GB1 adopts a chain weave structure with a padding yarn number of 0-1 / / ; comb GB2 adopts a plain warp weave structure with a padding yarn number of 1-2 / 1-0 / / ; comb GB3 adopts a weft-insertion weave structure with a padding yarn number of 0-0 / 3-3 / / , 0-0 / 4-4 / / or 0-0 / 5-5 / / . The yarn used in combs GB1 and GB2 is cotton yarn, and the yarn used in comb GB3 includes cotton yarn and cotton-covered spandex yarn.

[0040] Please refer to Figure 5 and Figure 6 The chain braiding of GB1, the warp plain weave of GB2, and the weft weave of GB3 together constitute the base structure of the fabric body. The warp loops in the fabric body are locked by the chain braiding, and the weft loops in the fabric body are formed by the interweaving of the warp plain weave and the weft weave.

[0041] For details, please refer to Figure 5 and Figure 6 In this embodiment, the guide bar GB1 is a closed-loop chain weave, forming continuous chain loop warp. This weave consists of a single yarn continuously looped on the same needle, with no transverse connection between the warp rows, thus forming a stable skeletal structure in the longitudinal direction of the fabric. The guide bar GB2 uses a plain warp weave, where the yarn alternately loops on adjacent needles, forming a transverse connection. This weave connects the independent warp rows of the guide bar GB1 into a stable mesh structure, providing transverse support and breathability. The guide bar GB3 uses a weft-inserted weave with a span of 3, 4, or 5 needles (3 needles is used as an example in this embodiment). The yarn is inserted transversely but not looped, hidden behind the loops of the guide bar GB1 and guide bar GB2, so that the long-span weft insertion provides uniform elastic support in the transverse direction of the fabric.

[0042] In this embodiment, please refer to Figure 4 The comb GB3 uses a long-span weft weft weft structure with a span of 3 to 5 stitches. In this embodiment, 3 stitches are used as an example to provide uniformly distributed elastic support in the transverse direction of the fabric body.

[0043] Furthermore, all three comb bars adopt a full-thread method. The cotton yarn used in comb bars GB1 and GB2 has a count of 50S / 1 to 80S / 1, is made of 100% long-staple cotton, and has a single yarn strength of not less than 250CN and a yarn evenness of not more than 12.3%. The cotton-wrapped spandex yarn used in comb bar GB3 has a specification of 40 / 40D, 50 / 40D or 60 / 30D, and a draft ratio of 3.8 to 4.0.

[0044] Specifically, the cotton yarn count is 50S / 1, the blended cotton is 100% long-staple cotton, the strength is 250CN, and the yarn evenness is 12.3%; the cotton-wrapped ammonia yarn is 50 (40D), and the draft ratio is 3.8.

[0045] Furthermore, when the combs GB1, GB2, and GB3 are woven into the fabric body, the humidity of the weaving environment is controlled at 60% to 70%.

[0046] This embodiment of the invention optimizes the weaving structure (GB1 braided comb + GB2 warp comb + GB3 weft comb) and selects high-quality yarn raw materials (long-staple cotton + spandex) to prepare an innovative fabric with a cotton content of over 95% by weight, which also has the functions of stability, elasticity, crispness, easy care and moisture-wicking and quick-drying.

[0047] Specifically, the fiber composition of the fabric consists of 96% cotton and 4% spandex by weight.

[0048] Example 2:

[0049] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment discloses a cotton elastic warp-knitted fabric, including a fabric body woven from combs GB1, GB2 and GB3. Comb GB1 adopts a chain weave structure with a padding yarn number of 0-1 / / ; comb GB2 adopts a plain warp weave structure with a padding yarn number of 1-2 / 1-0 / / ; comb GB3 adopts a weft-insertion weave structure with a padding yarn number of 0-0 / 3-3 / / , 0-0 / 4-4 / / or 0-0 / 5-5 / / . The yarn used in combs GB1 and GB2 is cotton yarn, and the yarn used in comb GB3 includes cotton yarn and cotton-covered spandex yarn.

[0050] For the same purposes as in Example 1, please refer to... Figure 5 and Figure 6 The chain braiding of GB1, the warp plain weave of GB2, and the weft weave of GB3 together constitute the base structure of the fabric body. The warp loops in the fabric body are locked by the chain braiding, and the weft loops in the fabric body are formed by the interweaving of the warp plain weave and the weft weave.

[0051] Similarly, please refer to Figure 5 and Figure 6In this embodiment, the guide bar GB1 is a closed-loop chain weave, forming continuous chain loop warp. This weave consists of a single yarn continuously looped on the same needle, with no transverse connection between the warp rows, thus forming a stable skeletal structure in the longitudinal direction of the fabric. The guide bar GB2 uses a plain warp weave, where the yarn alternately loops on adjacent needles, forming a transverse connection. This weave connects the independent warp rows of the guide bar GB1 into a stable mesh structure, providing transverse support and breathability. The guide bar GB3 uses a weft-inserted weave with a span of 3, 4, or 5 needles (3 needles is used as an example in this embodiment). The yarn is inserted transversely but not looped, hidden behind the loops of the guide bar GB1 and guide bar GB2, so that the long-span weft insertion provides uniform elastic support in the transverse direction of the fabric.

[0052] In this embodiment, the comb GB3 uses a long-span weft weft weft structure with a span of 3 to 5 stitches (3 stitches are used as an example in this embodiment) to provide uniformly distributed elastic support in the transverse direction of the fabric body.

[0053] Furthermore, all three comb bars adopt a full-thread method. The cotton yarn used in comb bars GB1 and GB2 has a count of 50S / 1 to 80S / 1, is made of 100% long-staple cotton, and has a single yarn strength of not less than 250CN and a yarn evenness of not more than 12.3%. The cotton-wrapped spandex yarn used in comb bar GB3 has a specification of 40 / 40D, 50 / 40D or 60 / 30D, and a draft ratio of 3.8 to 4.0.

[0054] Specifically, the cotton yarn count is 50S / 1, the blended cotton is 100% long-staple cotton, the strength is 250CN, and the yarn evenness is 12.3%; the cotton-wrapped ammonia yarn is 50 (40D), and the draft ratio is 3.8.

[0055] Furthermore, when the combs GB1, GB2, and GB3 are woven into the fabric body, the humidity of the weaving environment is controlled at 60% to 70%.

[0056] The difference from Example 1 is that the woven all-cotton elastic warp-knitted fabric is subjected to singeing, bleaching, dyeing, and finishing in sequence. In this example, the final finishing process includes liquid ammonia mercerizing and setting treatment, as detailed below:

[0057] Singeing process: Use a singeing machine to singe both sides of the greige fabric. The machine speed is controlled at 90m / min and the flame temperature is controlled at 800℃ to burn off the fuzz on the surface of the greige fabric and make the fabric smooth.

[0058] Scouring and bleaching process: The singed fabric is placed in a container containing a refining agent for scouring. Then, caustic soda and hydrogen peroxide are added sequentially. After scouring and bleaching at a certain temperature for 60 minutes, the temperature is lowered to 85℃, followed by washing with room temperature water and acid washing for 30 minutes, then washing and drying. The scouring and bleaching solution contains: refining agent 2.3g / L, caustic soda 2.65g / L, and hydrogen peroxide 1.2g / L, to remove natural impurities from the cotton fibers, improve whiteness and moisture absorption, and prepare for dyeing.

[0059] Dyeing process: The scalded and bleached fabric is immersed in a dyeing vat for dyeing treatment. Reactive dyes are selected for dyeing at 60℃, and the temperature is raised to 80℃ and kept at 40 minutes. After that, soaping and washing are performed to give the fabric a uniform color while maintaining the moisture absorption and breathability of cotton fibers.

[0060] Liquid ammonia mercerizing treatment: Before liquid ammonia treatment, the fabric is dried using a flat-lay dryer at a temperature of 130–160℃ and a speed of 10–30 m / min to ensure uniform moisture content. Subsequently, a loose-type liquid ammonia machine is used for mercerizing, allowing the liquid ammonia to penetrate into the amorphous regions of the fibers, eliminating internal stress and enhancing the fabric's dimensional stability, wrinkle resistance, and luster.

[0061] Setting process: A setting machine is used for setting, with the setting temperature controlled at 160-190℃ and the machine speed at 20-30m / min. At the same time, the fabric is controlled to reach the required width and weight, stabilize the width and weight, eliminate residual stress, and make the fabric stable in shape and soft in hand.

[0062] Furthermore, the all-cotton elastic warp-knitted fabric is subjected to structural testing, including checking for defects, loose threads, stains, holes, and other indicators and details.

[0063] Furthermore, after the inspection is completed, the cotton elastic warp-knitted fabric is tested. The specific contents of the fiber content test are shown in Table 1, and the elasticity, moisture absorption and quick-drying properties and coolness test are shown in Table 2.

[0064]

[0065] Table 1 Fiber Content Test

[0066] In this embodiment, the all-cotton elastic warp-knitted yarn is composed of 96% cotton and 4% spandex. This means that cotton fibers constitute the majority of the fabric's fiber composition, providing natural comfort and breathability, while the addition of spandex fibers gives the fabric good elasticity, making it more form-fitting and comfortable to wear. The reverse side of this fabric has a distinctive gauze texture and breathable mesh, giving it moisture-wicking and quick-drying properties.

[0067]

[0068] Table 2 Elasticity, Moisture Absorption and Quick-Drying Properties and Cooling Sensation Tests

[0069] In this embodiment, the transverse elastic elongation of the all-cotton elastic warp-knitted fabric is 35.0%, the longitudinal elastic elongation is 22.2%, the transverse elastic recovery rate is 59.1%, and the longitudinal elastic recovery rate is 65.7%. The principle lies in the fact that the long-span weft yarns of the guide bar GB3 form an elastic support network in the transverse direction, while the spandex fibers provide a high resilience rate; the chain braiding structure of the guide bar GB1 locks the longitudinal dimension, making the longitudinal recovery rate superior to the transverse recovery rate.

[0070] In this embodiment, the cotton fibers of the all-cotton elastic warp-knitted fabric provide excellent moisture absorption, and the warp-knitted mesh structure creates a capillary effect, promoting rapid diffusion and evaporation of moisture.

[0071] Example 3:

[0072] This embodiment provides a product, such as clothing, packaging, bedding, etc., which is made of the above-mentioned all-cotton elastic warp-knitted fabric, so that the finished product has the effects of structural stability, high elasticity, crispness, easy care and breathability.

[0073] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
