[0002] In the field of cotton sweater technology, one-piece cotton sweaters, as a comfortable and convenient garment, have received extensive attention and development in recent years. This type of sweater is usually made of 100% cotton and is deeply loved by consumers for its soft, breathable and skin-friendly properties.

[0003] However, due to the seamless weaving characteristics of one-piece cotton sweaters, the cotton fibers are easily deformed when subjected to external forces, causing the clothes to easily deform after being worn for a period of time, affecting the wearing effect and the service life of the clothes.

[0004] In addition, although there are some one-piece cotton sweaters with good elasticity on the market, these products often achieve improved elasticity by reducing the proportion of cotton components. The cotton content is mostly below 95%. Although the elasticity problem is alleviated, the comfort and breathability of pure cotton materials are lost.

[0005] Therefore, a method for preparing a high-elastic cotton sweater that can achieve both high elasticity and high cotton content is needed. Summary of the invention

[0006] In order to overcome the deficiencies of the prior art, the present invention provides a method for preparing an integrally formed high-elastic all-cotton sweater, which can achieve high elasticity and high cotton content at the same time.

[0007] The technical solution adopted by the present invention to solve its technical problem is:

[0030] Reference Figure 1 A method for preparing an integrally formed high-elastic cotton sweater comprises the following steps:

[0031] Step S1, select cotton fiber, use fine-staple cotton, and select 20D or 30D spandex yarn;

[0032] Step S2, spinning the embryo yarn, spinning the fine cotton into single yarn by combing siro spinning, and spinning the fine cotton and spandex yarn into cotton-covered spandex yarn by ring spinning;

[0033] Step S3, plying the embryo yarn, twisting two single yarns into a plied yarn;

[0034] Step S4, dyeing, dyeing the plied yarn and the cotton-baled spandex yarn to form colored yarn;

[0035] Step S5, weaving, weaving the pure cotton yarn and the cotton-covered spandex yarn through a 22-needle island fine fully-formed wool-covering device to form an integrated pure cotton high-elastic cotton sweater;

[0036] Step S6, washing and drying, washing and drying are performed through the knitted sweater garment washing process.

[0037] In the step S2, the specification of the cotton-baled ammonia is 60 / 30 or 60 / 20.

[0038] In the step S3, the yarn count of the ply yarn is 32S / 2 to 200S / 2.

[0039] In the step S5, the specific weaving method is: the cotton yarn uses colored yarn with a yarn count ranging from 32S / 2 to 200S / 2, the cotton-baled spandex uses yarn with a specification of 60 / 30 or 60 / 20, and is woven using the SHIMA SEIKI 22-needle fully formed wool-covering equipment. The cotton yarn and the cotton-baled spandex are fed into the loom at the same time, and are woven through the wool-covering yarn mouth, with the cotton yarn on the upper layer and the cotton-baled spandex on the lower layer, and a plain needle or double-sided structure is selected.

[0040] like Figure 2 As shown, the weaving is carried out using Shima Seiki's 22-needle fully-formed wool-covering equipment. Cotton yarn and cotton-baled spandex are fed into the loom at the same time and woven through the wool-covering yarn mouth. Cotton yarn 2 is on the upper layer and cotton-baled spandex 1 is on the lower layer. A 1×1 rib structure is selected.

[0041] The preparation method of the one-piece high-elastic cotton sweater also includes finished product inspection. After the finished garment is washed and dried, the one-piece high-elastic cotton sweater is inspected as a finished product.

[0042] Specifically, after washing and drying are completed, the one-piece high-elastic cotton sweater is inspected as a finished product, and indicators and details such as the size change rate after washing, wireless threads, stains, holes, etc. are checked.

[0043] Furthermore, after the inspection is completed, the one-piece high-elastic cotton sweater is subjected to finished product testing. The specific contents of the fiber content test are shown in Table 1, and the elasticity and pilling test are shown in Table 2.

[0044] Table 1 Fiber content test

[0045]

[0046] Table 2 Elasticity and pilling test

[0047]

[0048] Among them, the fiber composition of the one-piece high-elastic cotton sweater is 98.3% cotton and 1.7% spandex. This means that in the fiber composition of the clothing, cotton fibers occupy the vast majority, providing the clothing with natural comfort and breathability, while the addition of spandex fibers gives the clothing good elasticity, making the clothing more close-fitting and comfortable to wear.

[0049] The fiber content test follows a series of strict method standards, including FZ / T01057.1-2007, FZ / T01057.2-2007, FZ / T 01057.3-2007, FZ / T01057.4-2007 and GB / T 38015-2019, etc. These standards specify the specific methods, steps and precision requirements for fiber content testing, ensuring the accuracy and reliability of the test results.

[0050] Among them, the test item of tensile elastic elongation of one-piece high-elastic cotton sweaters is used to evaluate the elastic properties of clothing. In the test, the clothing was stretched 5 times in the vertical and horizontal directions respectively, and the elongation after each stretch was recorded. The measured results showed that the vertical tensile elastic elongation was 90.4%, and the horizontal tensile elastic elongation was 136.0%. These data show that the clothing can maintain good elastic deformation ability when stretched by external force, and can still return to its original state after multiple stretching.

[0051] Among them, the test item of the stretch elastic recovery rate of the one-piece high-elastic cotton sweater is used to evaluate the recovery ability of the clothing after stretching. Similarly, the clothing was stretched 5 times in the vertical and horizontal directions respectively, and the recovery rate after each stretching was recorded. The measured results show that the vertical stretch elastic recovery rate is 48.6%, and the horizontal stretch elastic recovery rate is 35.5%. Although the recovery rate is relatively low, considering that the clothing will be subjected to continuous stretching and compression during wearing, such a recovery rate can still meet the needs of daily wear.

[0052] Among them, the pilling level test item of one-piece high-elastic cotton sweaters is used to evaluate the anti-pilling performance of clothing. In the test, the clothing is subjected to friction and rubbing during daily wear, and then the surface is observed to see if pilling occurs. The actual test results show that the pilling level of the clothing is level 3, which means that under normal use and maintenance, the surface of the clothing is not prone to obvious pilling.

[0053] The above test items all follow the corresponding method standards, including FZ / T 70006-2004 (for evaluating elastic properties) and GB / T 4802.1-2008 (for evaluating anti-pilling properties). These standards specify the specific methods, steps and rating criteria of the tests, ensuring the accuracy and comparability of the test results.

[0054] In summary, by conducting fiber content tests, elasticity tests, and pilling tests on one-piece high-elastic cotton sweaters, we can comprehensively evaluate their quality performance and provide consumers with reliable product information.

[0055] In another embodiment, in the process of preparing an integrated high-elastic cotton sweater, high-quality fine cotton is first selected as the raw material, and 30D spandex is used to enhance elasticity. In the embryo yarn spinning stage, the fine cotton is spun into a 32S / 2 single yarn using combed siro spinning technology, and the fine cotton and 30D spandex are spun into a 60 / 30D cotton-baled spandex yarn using a ring spinning method. Subsequently, two single yarns are twisted to form a ply yarn, and the ply yarn count is 50S / 2. After dyeing, the colored yarn and the cotton-baled spandex yarn are fed into the Shima Seiki 22-needle fully formed wool-covering equipment for weaving. During the weaving process, the cotton yarn is located on the upper layer, and the cotton-baled spandex is located on the lower layer, and a plain weave structure is adopted to ensure that the clothes are soft and elastic. Finally, the knitted sweater garment washing process is used for washing and drying, and the finished product is strictly inspected to ensure that the size is stable and flawless.

[0056] In another embodiment, in order to prepare a high-count yarn integrated high-elastic cotton sweater, fine-staple cotton and 20D spandex yarn are selected as raw materials. In the embryo yarn spinning stage, the fine-staple cotton is spun into a high-count single yarn of 100S / 2, while the fine-staple cotton and 20D spandex yarn are spun into a cotton-baled spandex yarn of 60 / 20. After the two single yarns are twisted into a ply yarn, they are dyed. Subsequently, the colored yarn and the cotton-baled spandex yarn are fed into the loom at the same time using the SHIMA SEIKI 22-needle fully molded wool-covering equipment. The cotton yarn is located on the upper layer, and the cotton-baled spandex is located on the lower layer, and a double-sided tissue structure is used for weaving. After washing and drying, the finished product is carefully inspected to ensure that the clothing not only has excellent elasticity, but also has a delicate feel and exquisite appearance.

[0057] In another embodiment, fine-staple cotton and 30D spandex yarn are used to prepare an integrated high-elastic cotton sweater. In the embryo yarn spinning stage, the fine-staple cotton is spun into an ultra-high-count single yarn of 200S / 2, while the fine-staple cotton and 30D spandex yarn are spun into a cotton-baled spandex yarn of 60 / 30 specifications. After the two single yarns are twisted into a ply yarn and dyed, they are woven using the Shima Seiki 22-needle fully molded wool-covering equipment. During the weaving process, the cotton yarn and cotton-baled spandex are respectively located in the upper and lower layers of the fabric, and a 1×1 rib structure is adopted to give the clothing good elasticity and breathability. After washing and drying, the finished product is inspected to ensure that the size of the clothing is stable and the details are perfect.

[0058] In another embodiment, in the process of preparing an integrated high-elastic cotton sweater, high-quality fine cotton is first selected as the main fiber, and 30D spandex yarn is matched to enhance the elasticity of the clothing. In the embryo yarn spinning stage, the combed siro spinning technology is used to spin the fine cotton into a single yarn with a yarn count of 50S / 2. At the same time, the ring spinning method is also used to spin the fine cotton and 60 / 30 spandex yarn into cotton-wrapped spandex yarn, and then the two single yarns are twisted to form a plied yarn, which is then dyed.

[0059] During the weaving stage, Shima Seiki's 22-needle fully-formed wool-covering equipment was used to feed the colored yarn and cotton-baled spandex yarn into the loom at the same time. Through the wool-covering yarn mouth, an all-cotton high-elastic cotton sweater with cotton yarn on the upper layer and cotton-baled spandex on the lower layer was carefully woven. The flat needle structure was selected to ensure the comfort and elasticity of the clothes.

[0060] After weaving, the clothes are washed and dried, and the knitted sweater washing process is used to wash and dry the clothes. Finally, the finished products are strictly inspected, including the size change rate, thread ends, stains and holes, to ensure that each piece of clothing meets the quality standards.

[0061] In another embodiment, in order to prepare a high-quality one-piece high-elastic cotton sweater, fine cotton and 30D spandex yarn are selected as raw materials. In the embryo yarn spinning stage, the fine cotton is spun into a 100S / 2 high-count single yarn, and a 60 / 30 cotton-baled spandex yarn is spun at the same time.

[0062] Subsequently, the two single yarns were combined and dyed to obtain colorful colored yarn. During the weaving process, SHIMA SEIKI 22-needle fully-formed wool-covering equipment was selected to feed the colored yarn and cotton-covered spandex yarn into the loom at the same time, and the clothing was woven with a double-sided structure through the wool-covering yarn mouth.

[0063] After weaving, washing and drying, the finished product was comprehensively inspected, including fiber content test, elasticity and pilling test, etc. The test results showed that the fiber content of the clothing was 98.3% cotton and 1.7% spandex, the tensile elastic elongation and recovery rate reached a high level, and the pilling level was level 3, which fully proved its excellent quality and performance.

[0064] In another embodiment, fine cotton and 20D spandex yarn are selected to spin 60S / 2 single yarn and 60 / 20 cotton-covered spandex yarn. After plying and dyeing, the yarn is woven with a 1×1 rib structure using a Shima Seiki 22-needle machine. After washing and drying, the finished product is inspected, and the results show that the fiber content is accurate, the elasticity is good, and the pilling level meets the standard, ensuring the quality of the clothing.

[0065] In the above process, the embodiment of the present invention realizes the innovation of the preparation technology of one-piece high-elastic cotton sweater through a series of fine process steps. By selecting fine cotton and spandex yarn, and adopting combed siro spinning, ring spinning and other technologies, cotton fiber and spandex yarn are effectively spun into single yarn and cotton-wrapped spandex. Through the steps of embryo yarn plying, dyeing, weaving, etc., using 22-needle island fine fully formed wool-covering equipment, the cotton ply yarn and cotton-wrapped spandex yarn are perfectly integrated to form an one-piece high-elastic cotton sweater, which not only improves the elasticity of the sweater, but also ensures a high cotton content, thereby greatly improving the comfort of wearing. Through washing and drying treatment and finished product inspection, the present invention successfully overcomes the problems of easy deformation and poor wearing comfort of one-piece cotton sweaters, and achieves the technical effect of both high elasticity and high cotton content, which is very suitable for making sports and leisure products.
