Abstract
Description
Technical Field
[0001] The present application relates to the field of textile technology, and in particular to a pure cotton moisture-absorbing and quick-drying fabric and a woven fabric. Background Art
[0002] Many quick-drying fabrics on the market are made of synthetic fibers, which can be uncomfortable to wear. For those with sensitive skin, synthetic fibers are less comfortable than natural fibers like cotton and linen. Prolonged wear can cause a feeling of stuffiness or discomfort. Furthermore, the moisture-absorbing and quick-drying properties of many synthetic fabrics are achieved by adding chemical additives during the finishing process, which poses potential health risks and is generally not very durable. The moisture-absorbing and quick-drying properties are lost with repeated washings. Summary of the Invention
[0003] The present application provides a pure cotton moisture-absorbing quick-drying fabric and woven fabric, aiming to solve the technical problems of existing quick-drying fabrics such as discomfort, potential health risks, and short-lasting moisture-absorbing and quick-drying performance.
[0004] According to the first aspect of the present application, an embodiment provides a pure cotton moisture-absorbing and quick-drying fabric, comprising:
[0005] An inner layer, which is provided on a side in contact with human skin and comprises a first yarn;
[0006] A surface layer, the surface layer being arranged on a side away from human skin and opposite to the inner layer, the surface layer comprising a second yarn;
[0007] Wherein, the first yarn and the second yarn are knitted together, the first yarn is a cotton yarn with a twist of more than 1600 twists / m, and the second yarn is a cotton yarn with a twist of less than 750 twists / m.
[0008] In one embodiment, the first yarn is a high-twist yarn with a twist greater than or equal to 1800 twists / m and less than or equal to 2650 twists / m; and / or,
[0009] The second yarn is a super soft yarn, and the twist number is greater than or equal to 600 twists / meter and less than or equal to 750 twists / meter.
[0010] In one embodiment, the yarn count of the first yarn is greater than or equal to the yarn count of the second yarn.
[0011] In one embodiment, the yarn count of the first yarn is greater than or equal to 40 S / 1 and less than or equal to 80 S / 1; and / or,
[0012] The yarn count of the second yarn is greater than or equal to 30 S / 1 and less than or equal to 50 S / 1.
[0013] In one embodiment, the first yarn is combed compact spun cotton yarn with a Z twist direction; the second yarn is combed ring spun cotton yarn or combed compact siro spun cotton yarn with an S twist direction.
[0014] In one embodiment, the first yarn and the second yarn are arranged in a cotton-covered cotton plain knit.
[0015] In one embodiment, the first yarn and the second yarn are looped on the same needle path.
[0016] In one embodiment, the fabric has a gram weight of less than 190 g / m2.
[0017] In one embodiment, the fabric is finished using liquid ammonia finishing technology in the post-finishing stage.
[0018] According to the second aspect of the present application, an embodiment provides a woven fabric, which is made by cutting the fabric of the first aspect.
[0019] According to the above-described embodiments, the all-cotton moisture-absorbing and quick-drying fabric and woven fabric utilize cotton yarn with a twist of at least 1600 twists / meter for the inner layer and less than 750 twists / meter for the outer layer. The inner layer's cotton yarn is denser, with smaller interfiber spaces, while the outer layer's cotton yarn is more sparse, with larger interfiber spaces. The outer layer absorbs water more readily than the inner layer, and the outer layer has a larger diffusion area than the inner layer, thereby achieving a moisture-absorbing and quick-drying effect. When a person sweats, sweat quickly diffuses from the inner layer to the outer layer. This fabric achieves a permanent moisture-absorbing and quick-drying effect through yarn twist differences and structure at the yarn ends. Furthermore, both the first and second yarns are cotton yarn, resulting in an all-cotton fabric. This all-cotton fabric exhibits excellent breathability, is soft, and comfortable, and does not cause irritation or discomfort when in contact with the skin, posing no health risks. Therefore, the all-cotton moisture-absorbing and quick-drying fabric of the present application not only absorbs moisture and dries quickly, but also has a long-lasting moisture-absorbing and quick-drying performance. In addition, the fabric is healthy and does not cause irritation or discomfort to the skin. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.
[0024] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various implementations, and the operational steps involved in each embodiment may be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.
[0025] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).
[0026] Currently, many quick-drying fabrics are made of synthetic fibers, which are far less comfortable than natural fibers. Wearing them for extended periods can cause a feeling of stuffiness or discomfort. Furthermore, the moisture-absorbing and quick-drying properties of many synthetic fabrics are achieved by adding chemical additives during the finishing stage, which poses potential health risks. Furthermore, their moisture-absorbing and quick-drying properties diminish with repeated washing, making them less durable.
[0027] In view of this, the present application provides a pure cotton moisture-absorbing and quick-drying fabric and woven fabric to improve the health, safety and comfort of the fabric, and also make the moisture-absorbing and quick-drying performance of the fabric durable.
[0028] See also Figure 1 The present invention provides an all-cotton moisture-absorbing and quick-drying fabric, comprising an inner layer and an outer layer. The inner layer is disposed on a side in contact with human skin, and the outer layer is disposed on a side away from human skin, with the inner layer and the outer layer being disposed opposite each other. The inner layer comprises a first yarn 10, and the outer layer comprises a second yarn 20. The first yarn 10 and the second yarn 20 are knitted together. The first yarn 10 is a cotton yarn having a twist of 1600 twists / meter or more, and the second yarn 20 is a cotton yarn having a twist of 750 twists / meter or less.
[0029] The above technical solution utilizes cotton yarn with a twist of at least 1600 twists / meter for the inner layer of the fabric and a twist of less than 750 twists / meter for the outer layer. The inner layer's cotton yarn is denser, with smaller interfiber spaces, while the outer layer's yarn is more sparse, with larger interfiber spaces. This allows the outer layer to absorb water more easily than the inner layer, and the surface layer has a larger diffusion area than the inner layer, resulting in a fabric that absorbs moisture quickly and dries quickly. When a person sweats, sweat quickly diffuses from the inner layer to the outer layer. This fabric achieves permanent moisture absorption and quick-drying properties through yarn twist differences and structure at the yarn ends. Furthermore, both the first yarn 10 and the second yarn 20 are cotton yarns, resulting in a pure cotton fabric. Pure cotton fabrics offer excellent breathability, allowing air to circulate freely and facilitating rapid evaporation of sweat, thereby keeping the skin dry. Furthermore, pure cotton fabrics are soft and comfortable, and do not cause irritation or discomfort when in contact with the skin. Therefore, the all-cotton moisture-absorbing and quick-drying fabric of the present application not only absorbs moisture and dries quickly, but also has a long-lasting moisture-absorbing and quick-drying performance. In addition, the fabric is healthy and does not cause irritation or discomfort to the skin.
[0030] In one embodiment, the first yarn 10 is a strongly twisted yarn. The first yarn 10 is placed close to the skin. Using a strongly twisted yarn as the first yarn 10 can improve the cooling, sweat-relieving and non-sticky properties of the fabric, keeping the skin relatively dry.
[0031] In one embodiment, the twist of the first yarn 10 is greater than or equal to 1800 twists / m and less than or equal to 2650 twists / m. In a specific implementation, the twist of the first yarn 10 can be 1800 twists / m, 1900 twists / m, 2000 twists / m, 2100 twists / m, 2200 twists / m, 2300 twists / m, 2400 twists / m, 2500 twists / m, 2600 twists / m, etc.
[0032] In one embodiment, the second yarn 20 is a super soft yarn. The super soft yarn is extremely soft, feels very comfortable, and can bring a warm touch. By using the super soft yarn as the second yarn 20, the moisture absorption and quick-drying performance of the fabric can be increased, and the fabric has a soft and skin-friendly feel.
[0033] In one embodiment, the twist of the second yarn 20 is greater than or equal to 600 twists / m and less than or equal to 750 twists / m. In a specific implementation, the twist of the second yarn 20 can be 600 twists / m, 650 twists / m, 700 twists / m, 750 twists / m, etc.
[0034] In one embodiment, the yarn count of the first yarn 10 is greater than or equal to the yarn count of the second yarn 20. Yarn count is generally measured by fineness, which is an important characteristic of yarn. The finer the yarn, the higher the fiber quality requirements, resulting in a smoother, finer, and higher-quality fabric. The larger the yarn count, the finer the yarn. In this embodiment, the yarn count of the first yarn 10 is equal to the yarn count of the second yarn 20.
[0035] In one embodiment, the yarn count of the first yarn 10 is greater than or equal to 40 S / 1 and less than or equal to 80 S / 1. In a specific implementation, the yarn count of the first yarn 10 can be 40 S / 1, 50 S / 1, 60 S / 1, 70 S / 1, 80 S / 1, etc.
[0036] In one embodiment, the yarn count of the second yarn 20 is greater than or equal to 30 S / 1 and less than or equal to 50 S / 1. In a specific implementation, the yarn count of the second yarn 20 can be 30 S / 1, 40 S / 1, 50 S / 1, etc.
[0037] In one embodiment, the first yarn 10 is a combed compact-spun cotton yarn with a Z twist; the second yarn 20 is a combed ring-spun cotton yarn or a combed compact-siro-spun cotton yarn with an S twist. Skew is a condition in which the weave of a fabric or knitted fabric becomes tilted or twisted in a serpentine pattern. This phenomenon is called weft skew. This is particularly noticeable in plain weave fabrics, and textiles made with such fabrics will be defective, so it should be avoided. By combining Z-twist and S-twist yarns, the risk of weft skew can be reduced, especially when knitting plain weave fabrics, which helps the fabric remain flat.
[0038] In one embodiment, the first yarn 10 and the second yarn 20 are knitted in a cotton-on-cotton plain knitting structure. That is, the fabric is woven from the first yarn 10 and the second yarn 20 in a cotton-on-cotton plain knitting structure.
[0039] The first yarn 10 and the second yarn 20 are arranged in a loop on the same needle path. During weaving, the first yarn 10 and the second yarn 20 are fed simultaneously from the yarn mouth of the single-sided circular knitting machine, and the first yarn 10 and the second yarn 20 are formed into a plurality of loop structures on the same needle path, and then the plurality of loop structures are knitted into a plain weave. Figure 2 shown.
[0040] In one embodiment, the fabric has a grammage of less than 190 g / m². The lower the fabric's grammage per unit area, the greater its contact surface with air, allowing for faster moisture loss. Therefore, under the same hygroscopicity conditions, the lower the fabric's grammage, the better its cooling and breathability. Preferably, the fabric has a grammage greater than or equal to 160 g / m² and less than or equal to 180 g / m².
[0041] In one embodiment, the fabric is finished using liquid ammonia finishing technology during the post-finishing stage. Without liquid ammonia treatment, the cotton fibers have natural twists and grooves within them, resulting in a round cross-section. After liquid ammonia treatment, most of the natural twists disappear, the fibers become straight, and the grooves within them disappear, resulting in a round cross-section and a fuller, rounder fiber. This improves water absorption, and the elimination of grooves within the fibers significantly increases the evaporation rate of liquid, allowing the fabric to dry quickly after absorbing water.
[0042] In a specific implementation, the fabric is placed in anhydrous liquid ammonia at -40°C for 3 minutes, then dried in an oven, and finally washed with water to remove residual liquid ammonia until it becomes neutral, thereby obtaining a liquid ammonia-treated fabric. The drying conditions in the oven are: drying temperature 60°C, drying time 10 minutes.
[0043] The embodiment of the present application further provides a woven fabric, which is made from the above-mentioned fabric. The woven fabric can be a T-shirt, underwear, etc.
[0044] The following specific examples illustrate that the fabric of the present application has excellent moisture absorption and quick-drying properties.
[0045] Example 1
[0046] The all-cotton moisture-absorbing, quick-drying fabric in this embodiment is woven from high-twist cotton yarn and super-soft cotton yarn using a cotton-covered cotton plain knit structure. The high-twist yarn has a twist of 1900 twists / m and a yarn count of 40S / 1, while the super-soft yarn has a twist of 700 twists / m and a yarn count of 40S / 1. The high-twist yarn is spun using combed compact spinning with a Z twist, while the super-soft yarn is spun using combed compact siro spinning with an S twist. The high-twist and super-soft yarns are looped on the same needle path.
[0047] The woven fabric is subjected to processes such as boiling and bleaching, dyeing, liquid ammonia finishing and other finishing processes to obtain the finished fabric, and the gram weight of the finished fabric is 180 grams per square meter.
[0048] In accordance with the requirements for quick-drying performance in GB-T 21655.2-2019 and the requirements for cool contact sensation in GB-T 35263-2017, this moisture-absorbing and quick-drying fabric has a dry, non-sticky inner layer next to the skin, a noticeable cool contact sensation, and a delicate and soft outer layer, enhancing the fabric's quality. The fabric's moisture absorption, quick-drying properties, and cool contact sensation were tested, and the data are shown in the table below:
