The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0024] In the hot and humid conditions of summer, it is very easy to sweat a lot when commuting or doing light outdoor activities. Conventional cotton fabric clothing has good moisture absorption properties but poor moisture conduction properties. After sweating a lot, the fabric will stick to the skin, the feeling of wetness is very obvious, and the body feels uncomfortable. At the same time, you may catch a cold and affect your health.

[0025] In the prior art, a one-way moisture conduction process is generally adopted to make the skin-contacting surface water-repellent and the non-skin-contacting surface hydrophilic. At the same time, a part of fine moisture conduction channels is left on the skin-contacting surface to allow sweat to be conducted to the non-skin-contacting surface, which can reduce the sticky feeling to a certain extent; however, the current moisture conduction process will cause new problems. After the skin-contacting surface is made water-repellent, the skin-affinity will decrease, the human body will feel stuffy when wearing it, and the wearing comfort will be greatly reduced.

[0026] The present application provides a pure cotton cool and sweat-removing knitted fabric, the skin-contacting side is close to the skin, which is more comfortable, and the non-skin-contacting side is not close to the skin, which is cooler. The fabric is woven to form a double-sided air layer structure, so that the fabric has the characteristics of both sweat-removing and comfort.

[0027] Please refer to Figure 1 and Figure 2 In one embodiment, a pure cotton cool and sweat-removing knitted fabric is provided, including an inner layer 1, an intermediate layer 2 and an outer layer 3. The inner layer 1 and the outer layer 3 form a double-sided air layer structure through the intermediate layer 2; the yarn of the outer layer 3 is set to a cotton-cotton structure, including a water-repellent inner core 31 and a hydrophilic surface layer 32. The intermediate layer 2 is used to connect the inner layer 1 and the outer layer 3 and conduct moisture, and the hydrophilic surface layer 32 is used to absorb and quickly evaporate water marks to keep the water-repellent inner core 31 dry.

[0028] Furthermore, the inner layer 1 is the skin-contacting surface and is woven with strong twist yarn, the outer layer 3 is the non-skin-contacting surface and is woven with low twist yarn, the middle layer 2 is made of ultra-fine stretch yarn, and a double-sided loop weaving process is used to connect the inner layer 1 and the outer layer 3 for moisture conduction, so that an air layer is formed between the inner layer 1 and the outer layer 3.

[0029] The all-cotton cool and sweat-removing knitted fabric in the embodiment of the present application has an inner layer 1 and an outer layer 3 forming a double-sided air layer structure through the middle layer 2, which improves the air permeability of the fabric; the outer layer 3 has a water-repellent inner core and a hydrophilic surface layer, and the middle layer 2 can conduct sweat from the inner layer 1 to the outer layer 3 and quickly absorb and evaporate it through the hydrophilic surface layer 32, so that the water-repellent inner core 31 remains dry, the fabric will not get wet, the condition of sweat sticking to the skin is reduced, the cool contact feeling of the fabric is improved while ensuring the comfort of the fabric.

[0030] Among them, strong-twist yarn has good dimensional stability and small shrinkage after washing. There is no need to worry about shrinkage after washing for clothing or other textiles made of fabrics woven from strong-twist yarn. Strong-twist yarn has good gloss and feels very smooth and comfortable. It is more suitable for making skin-contact fabrics without causing harm to the skin. It also has better air permeability and moisture resistance. Fabrics woven from low-twist yarn are super soft and absorbent. The softness of low-twist yarn fabrics not only improves the wearing comfort, but also increases the fluffiness of the fabric, making it excellent in sweat absorption.

[0031] In the embodiment of the present application, in order to meet the requirements of non-stickiness and wearing comfort at the same time, two yarns with different twists are used, with strong-twist yarns sticking to the skin and low-twist yarns not sticking to the skin. The structure adopts a double-sided air layer structure, the skin-touching surface of the inner layer 1 is entirely woven with strong-twist yarns, and the non-skin-touching surface of the outer layer 3 is woven with low-twist yarns, and they are connected in the middle by an ultra-fine elastic yarn. Liquid ammonia is also used in the post-finishing process to further improve the moisture conduction performance of the yarn and enhance the cool contact feeling of the fabric. Finally, the skin-stickiness of the fabric can be controlled within 3cn, and the cool contact feeling can reach above 0.26J / (cm〃s).

[0032] In another embodiment, the outer layer 3 is woven from super soft yarn, and the yarn is processed through super soft spinning technology, so that the yarn is softer, smoother and more comfortable after processing.

[0033] Furthermore, the length of a yarn weighing 1 gram that can be pulled out is called the number of yarns. Generally speaking, the larger the number of yarns, the thinner the yarn. High-count yarns are generally yarns with a high count of 40 or more. In the embodiment of the present application, the fabric yarn adopts high-count yarns. Specifically, the yarn count range of the yarn used for the fabric is 50S / 1-100S / 1, and the yarn count of the yarn used for the outer layer 3 is not greater than the yarn count of the yarn used for the inner layer 1, that is, the yarn count of the non-skin-contacting surface of the outer layer 3 can be the same as the yarn count of the skin-contacting surface of the inner layer 1, and the touch of the inner and outer layers 3 is the same, or the yarn count of the non-skin-contacting surface of the outer layer 3 is less than the yarn count of the skin-contacting surface of the inner layer 1, and the outer layer 3 feels rougher than the inner layer 1.

[0034] The embodiment of the present application uses yarns with higher counts, so its weaving density is higher, the fabric is more delicate, soft and comfortable, and can reduce the discomfort caused by friction when in contact with the skin; and the high-count yarn fabric has a thin fabric line and fits the skin more closely, and has very good skin-friendliness; at the same time, the weaving method of the high-count yarn allows air to circulate between the fabrics, thereby effectively maintaining transparent breathability and further improving comfort.

[0035] Furthermore, the middle layer 2 is made of spandex yarn. Under standard conditions, the fiber fineness is generally defined by the weight of 9000-meter-long fibers. In the embodiment of the present application, spandex yarn with a count of 20d-40d is used to weave the middle layer 2. Spandex yarn has extremely high elasticity and recovery, can withstand great stretching and compression, and has good air permeability and poor moisture absorption. As the middle layer 2, spandex yarn is used to further enhance the elasticity and recovery of the fabric, and at the same time facilitates moisture conduction to allow moisture to evaporate quickly, thereby improving the coolness and comfort of the fabric.

[0036] In the embodiment of the present application, in order to further ensure the cool feeling, sweat-relief and comfort of the fabric, the cotton selection requirements are: length is 36mm-37mm, strength is not less than 40cn / dtex, micronaire value is within 3.7-4.2, and impurity content is within 2.2%; yarn process parameters: yarn count range: 50-100S / 1, the spinning process adopts combed compact spinning; strong twist yarn process: British twist coefficient is 4.8-7.6, breaking strength ≥18cN / tex, and hairiness value H≤3.2; super soft yarn process: British twist coefficient is 2.8-3.3, breaking strength is greater than or equal to 14.5cN / tex, and hairiness value H≥5.0; the overall gram weight range of the fabric is 160g / ㎡-220g / ㎡, that is, the gram weight per square meter of the fabric in this embodiment is 160g-220g.

[0037] After the fabric is woven, it is post-finished, first through the scouring and bleaching pre-treatment process, flat drying, and then through the knitting liquid ammonia treatment, liquid flow dyeing, shaping, calendering and pre-shrinking. The knitting liquid ammonia process: machine speed: 20-25m / min, liquid ammonia temperature: -34℃, upper blanket temperature of the cloth feeding unit: 110℃, lower blanket temperature of the cloth feeding unit: 110℃, upper reaction zone temperature: 60℃, lower reaction zone temperature: 50℃, upper blanket temperature of the cloth out: 100℃, lower blanket temperature of the cloth out: 100℃, liquid ammonia tank tension: 50N, drying tank tension: 40N, evaporation tank tension: 40N.
