Description

Technical Field

[0001] This invention relates to a functional fabric with a high evaporation rate and a method for manufacturing the same, and more specifically, to a functional fiber product that combines high moisture wicking and high moisture wicking properties, and a method for manufacturing the product that combines high moisture wicking and high moisture wicking properties, such that the evaporation rate of the product is higher than 0.44 g / h. Background Technology

[0002] Beyond their basic functions of providing shelter and warmth, clothing, apparel, bedding, and other garment products have seen increasing demands from society as people's needs evolve. Among these demands, the need for moisture-wicking and quick-drying garments for everyone, especially those in sweaty or damp environments and those prone to sweating, has been a major focus for the apparel and home textile industry. Currently, the Guinness World Record for evaporation rate, measured using fabric as a testing target, is 0.44 g / h. However, while products using this record offer improved comfort compared to traditional fabrics, the increase in evaporation rate is limited and still insufficient to meet the moisture-wicking and quick-drying needs of everyone, especially those prone to sweating, in sweaty or damp environments.

[0003] The "sweating environment" mentioned here refers to environments and scenarios that cause excessive sweating, such as hot seasons, high-temperature work environments, and high-intensity exercise / work scenarios. The "humid environment" refers to high-humidity natural or work environments, such as waterside environments (islands, riverbanks) in winter and spring. The "prone-to-sweating population" refers to people who sweat easily due to their constitution or medical conditions. In these environments and among these people, the evaporation rate of clothing, sheets, etc. (hereinafter referred to as "fabric") is usually much lower than the rate at which human sweat is excreted, causing a large amount of sweat to "accumulate" inside the fabric, resulting in a very unpleasant feeling.

[0004] The ability of clothing to absorb sweat (moisture absorption) and its ability to release sweat into the air (moisture wicking) are inherently contradictory. That is, strong moisture absorption indicates a strong ability to adsorb and lock in water molecules; while strong moisture wicking indicates a strong ability to repel water molecules. Clearly, simultaneously pursuing high levels of both moisture absorption and wicking is a paradox, highlighting the technological difficulty involved. Despite years of significant investment in the apparel and home textile industry, the evaporation rate remains at 0.44 g / h, demonstrating that even a 0.01 g / h increase in evaporation rate can be considered a technological breakthrough.

[0005] As mentioned above, it is difficult to find materials that combine high moisture absorption and high moisture removal capabilities in existing technologies. Research institutions can only try to balance these two indicators, seeking a relative balance between these two seemingly contradictory metrics. This is the main reason why research results have been slow to improve over the years.

[0006] Among natural fibers (plant materials such as cotton and linen), linen has better moisture absorption, moisture release, and breathability than cotton. However, in current technology, the evaporation rate of pure linen fabric is less than 0.44 g / h, which cannot exceed the Guinness World Record for the highest evaporation rate of fabric.

[0007] On the other hand, since natural fibers do not possess the dual high characteristics of the aforementioned two indicators, traditional apparel technologies have failed to solve the problem of achieving both. Modifying natural fibers requires methods such as gene conversion, hybridization / grafting, etc., and its research and verification cycle depends on the plant's growth cycle, resulting in poor timeliness and high uncertainty. Therefore, research on the modification of natural fibers requires significant investment and has a long cycle. Consequently, modern technology has shown great enthusiasm and made significant progress in the research and development of synthetic fibers, and the usage of synthetic fibers has far exceeded that of natural fibers. Among synthetic fibers for apparel, polyester, with its many advantages, occupies more than 70% of the global synthetic fiber market. The modification of synthetic fibers has a short operation and verification cycle and low investment. Therefore, technological progress in the modification research and development of synthetic fibers, especially polyester, is faster, particularly in improving individual indicators of the aforementioned two indicators, which have seen significant improvements in recent years. The technologies with patent numbers ZL2013104209539 and / or ZL2011102252658 have achieved significant improvements in single indicators such as moisture absorption capacity and low-temperature dyeing. However, they do not have an advantage in improving both of these indicators and cannot solve the problem of improving the comfort of all people, especially those prone to sweating, in sweaty or humid environments.

[0008] Secondly, in curtain-type humidifiers (liquid diffusers), a cloth curtain structure is used, with one end immersed in the liquid and the other end placed in the airflow. The cloth curtain diffuses the liquid to the largest possible area within it, and then the flowing air removes the liquid from the curtain surface, achieving diffusion of the liquid into the air. In this process, the cloth curtain needs both high moisture absorption capacity to meet the need for rapid liquid supply and high moisture release capacity to meet the need for rapid liquid evaporation.

[0009] Conversely, in curtain dehumidifiers, a cloth curtain structure is also used. Part of the cloth curtain is placed in the flowing air, and its high moisture conductivity captures water molecules in the air, causing them to adhere to the cloth curtain. Then, it enters the regeneration environment, where its high moisture release property releases water molecules into the regeneration environment, which condenses into water droplets and is collected by a water container, thus achieving air dehumidification.

[0010] In summary, curtain-type humidifiers / humidifiers also require a fabric with both high moisture absorption and release properties to improve the product's efficiency and application effect. Summary of the Invention

[0011] This invention addresses the limitations of traditional technologies in actual production and market demands by providing a functional fabric with a high evaporation rate and its manufacturing method, thereby solving the problems of existing technologies.

[0012] Based on practical needs, this specification provides one or more embodiments of a functional fabric with a high evaporation rate and a method for manufacturing the same, overcoming the limitations and defects of the current technology listed in the background section, and providing a practical solution. The technical solution of this invention is as follows: The present invention provides a functional fabric with a high evaporation rate and a method for manufacturing the same, wherein: The functional fabric is mainly composed of a blend of high moisture release fibers and high moisture wicking fibers; wherein, the high moisture wicking fibers are made of iterative polyester material, and the iterative polyester material is a material made by the technology described in patent number ZL201310420953.9 and / or patent number ZL201110225265.8. The manufacturing method includes: High moisture-wicking fiber manufacturing process: The iterative polyester material is made into fibers, and after stretching and / or texturing processes, fiber A is produced; Process for manufacturing high moisture-releasing fibers: Fiber B is made from high moisture-releasing materials or blends containing high moisture-releasing materials; Fabric manufacturing process: Fabric is made using fiber A and fiber B.

[0013] This solution uses a blend of two types of fibers (highly wicking and highly releasing moisture) to create the fabric. Since both types of fibers exceed either the high wicking or high releasing moisture performance standard, existing technologies cannot achieve both high performance standards for a single fiber type. Therefore, this solution uses a blend of the two types of fibers, allowing them to contact each other within the fabric. The highly wicking fibers, acting as the primary absorbent, rapidly absorb liquid into the fabric and diffuse it over a larger area through the contact points between the two types of fibers. Then, the highly releasing moisture fibers, acting as the primary absorbent, evaporate the liquid into the surrounding air, achieving both high wicking and high releasing moisture, i.e., quick-drying.

[0014] Compared to existing technologies or technologies that use fabrics made from single-type fibers, this solution uses iterated polyester as a highly moisture-wicking material, which has industry-leading moisture absorption and wicking properties. It can introduce more liquid into the fabric more quickly and efficiently, and through contact with highly moisture-releasing fibers, guide the liquid to the highly moisture-releasing fibers, which then evaporate the liquid into the surrounding air at a higher moisture release rate.

[0015] As a further technical solution, the highly moisture-releasing material is a hemp material, including ramie and / or flax and / or jute and / or sisal and / or hemp and / or abaca.

[0016] Linen possesses the best water-draining and breathability among natural fibers to date, i.e., high moisture release, but its moisture-wicking properties are not particularly advantageous. Since the evaporation rate of various fiber materials is related to the fiber's inherent moisture content, this solution combines linen fibers with highly moisture-wicking iterative polyester fibers. During liquid evaporation, the iterative polyester fibers promptly deliver sufficient liquid to the linen fibers, placing the linen fibers under optimal humidity conditions for evaporation, thus improving the fabric's evaporation rate.

[0017] As a further technical solution, the highly moisture-wicking fiber is in the form of a mesh or porous structure; The process for manufacturing the high moisture-release fiber is as follows: the liquid-soluble material and the high moisture-release material are respectively made into fiber B1 and fiber B2, and then the fiber B1 and fiber B2 are blended into fiber B through a spinning process; the liquid-soluble material is a spinnable material that can be dissolved in a liquid solvent. The fabric manufacturing process includes: Primary fabric manufacturing process: Primary fabric is made from fiber A and fiber B; Secondary fabric manufacturing process: The primary fabric is placed in a solvent that can dissolve the liquid-soluble material, and rapid dissolution conditions are applied until the liquid-soluble material dissolves in the solvent to produce the secondary fabric; Finished fabric manufacturing process: The secondary fabric is washed, dried and smoothed to form the finished fabric.

[0018] This solution, referred to as the "separate weaving-then-dissolving solution," involves mixing highly moisture-wicking materials with soluble materials to create fibers during the manufacturing process of high-moisture-release fibers. These fibers are then blended with highly moisture-wicking polyester fibers and woven into fabric. The soluble materials are then dissolved, resulting in a honeycomb structure in the highly moisture-wicking fibers, providing better breathability. This increases the contact area between the highly moisture-wicking fibers and the air, significantly improving the fiber's evaporation rate. Referring to the previous technical solution, after mixing the two types of fibers (highly moisture-wicking and highly moisture-release fibers), the highly moisture-wicking fibers provide superior evaporation humidity for the highly moisture-release fibers. Combined with the better breathability of the highly moisture-wicking fibers in this solution, an even higher evaporation rate can be achieved.

[0019] As a preferred embodiment, the liquid-soluble material is a water-soluble material, and its solvent is water.

[0020] This solution uses water as a solvent, which can reduce solvent costs, reduce post-process waste disposal costs, and avoid environmental pollution.

[0021] As a preferred embodiment, the rapid dissolution conditions include: Heating to keep the solvent at a constant temperature, and / or This causes relative movement between the solvent and the primary fabric, accelerating the dissolution process.

[0022] This solution, by considering the solvent temperature and its relative motion with the fabric, offers the possibility of accelerating the dissolution of liquid-soluble materials in the secondary fabric manufacturing process, which is beneficial to improving production efficiency and indirectly reducing production costs.

[0023] As an optional technical solution, the high moisture release fiber and the high moisture wicking fiber exist in the fabric in the form of ply yarn or core-spun yarn; The process for manufacturing the high moisture-releasing fiber is as follows: fiber B is manufactured using a high moisture-releasing material; The fabric manufacturing process includes: Blended fiber manufacturing process: Fiber B and fiber A are processed by core-sizing or doubling to produce blended fiber C; Finished fabric manufacturing process: Using blended fiber C, the finished fabric is woven through a weaving process.

[0024] This scheme, referred to as the "combined weaving scheme," involves "combining" highly moisture-releasing fibers and highly moisture-wicking fibers into fiber C through core-spun or doubling processes. Then, fiber C is woven into the finished fabric using a weaving process. Compared to the aforementioned separate weaving-then-solidification scheme, in this scheme, the highly moisture-releasing fibers and highly moisture-wicking fibers are "combined" before weaving, resulting in a larger contact area between the two types of fibers. This allows the highly moisture-wicking fibers to transfer liquid to the highly moisture-releasing fibers with higher efficiency, thereby improving the evaporation rate of the fabric.

[0025] As an optional technical solution, the high moisture release fiber manufacturing process is: to manufacture fiber B from the high moisture release material; The fabric manufacturing process includes: The finished fabric is woven using fiber B and fiber A through a weaving process.

[0026] This solution, referred to as the "separate weaving solution," involves separately and independently fabricating fibers from highly moisture-releasing and highly moisture-wicking materials, which are then woven into finished fabrics. Compared to the aforementioned separate weaving-then-solvent and ply-weaving solutions, this solution retains the technical concept of "selectively combining" the properties of highly moisture-releasing and highly moisture-wicking fibers. Furthermore, it achieves the simplest manufacturing process and the lowest process cost, making it suitable for applications requiring slightly lower evaporation rates, thus achieving cost-effectiveness.

[0027] As an optional technical solution, the high moisture release fiber and the high moisture wicking fiber exist in the fabric in the form of doubly woven or core-spun yarn, and the high moisture release fiber is in the form of a mesh or porous structure. The process for manufacturing the high moisture-release fiber is as follows: the liquid-soluble material and the high moisture-release material are respectively made into fiber B1 and fiber B2, and then the fiber B1 and fiber B2 are blended into fiber B through a spinning process; the liquid-soluble material is a spinnable material that can be dissolved in a liquid solvent. The fabric manufacturing process includes: Blended fiber manufacturing process: Fiber B and fiber A are processed by core-sizing or doubling to produce blended fiber C; Primary fabric manufacturing process: using blended fiber C, the primary fabric is woven through a weaving process. Secondary fabric manufacturing process: The primary fabric is placed in a solvent that can dissolve the liquid-soluble material, and rapid dissolution conditions are applied until the liquid-soluble material dissolves in the solvent to produce the secondary fabric; Finished fabric manufacturing process: The secondary fabric is washed, dried and smoothed to form the finished fabric.

[0028] This scheme, referred to as the "combined-ply weaving followed by solvent dissolution scheme," involves weaving fiber C, made from a mixture of highly hygroscopic and liquid-soluble materials, together with highly hygroscopic iterative polyester fibers to form a fabric. The fabric is then soaked in a solvent to dissolve the liquid-soluble material in fiber C, retaining only the highly hygroscopic material. This process creates a mesh or porous structure in fiber C, increasing its contact area with air and improving its moisture release. In this scheme, because the highly hygroscopic mesh or porous fiber C is woven together with the highly hygroscopic iterative polyester fibers, compared to the separate weaving followed by solvent dissolution scheme and the separate weaving scheme, the two types of fibers have a larger contact area, which is beneficial for increasing the liquid supply rate to the highly hygroscopic fiber C, thereby increasing the fabric's evaporation rate. Furthermore, compared to the combined-ply weaving scheme, the highly hygroscopic fiber in this scheme has a mesh or porous structure, providing a larger contact area with air, which is beneficial for improving the fiber's moisture release performance and thus increasing the fabric's evaporation rate.

[0029] As an optional technical solution, the water-soluble material is vinylon, also known as vinylon.

[0030] This solution utilizes mature technologies and combines them with the technical concepts of this application, achieving mature implementation results and lower process costs.

[0031] In this application: The conjunction “and / or” means either that the items described before and after the conjunction are selected individually, or that the items described before and after the conjunction are selected simultaneously. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the accompanying drawings: Figure 1 Page 1 of the test report for high-evaporation-rate functional fabrics manufactured using the discrete weaving-then-solvent method; Figure 2 Page 2 of the test report for high evaporation rate functional fabrics manufactured using the discrete weaving-then-solvent method. Detailed Implementation

[0033] Example 1 – Manufacturing high-evaporation-rate functional fabrics using a discrete weaving-then-solvent method Backup materials: ① Iterative polyester made using the technology described in patents 201310420953.9 and 201110225265.8; ② Ramie; ③ Vinylon; Manufacturing methods include: High moisture-wicking fiber manufacturing process: The iterative polyester material is made into fibers, and after stretching and / or texturing processes, fiber A is produced; The process of making high moisture-release fiber: Water-soluble vinylon and ramie are made into fiber B1 and fiber B2 respectively, and then fiber B1 and fiber B2 are blended into fiber B through a spinning process. Primary fabric manufacturing process: Primary fabric is made from fiber A and fiber B; Secondary fabric manufacturing process: Place the primary fabric in hot water, heat it to about 100°C, and make the water flow or make the primary fabric sway in the water to accelerate the dissolution process until fiber B1 in fiber B dissolves in the water. At this point, the secondary fabric is made. Finished fabric manufacturing process: The secondary fabric is treated with washing, drying, and smoothing to form the finished fabric.

[0034] In this embodiment, soluble vinylon fiber B1 and ramie fiber B2 are blended into fiber B through a spinning process. Then, it is blended with highly moisture-wicking iterative polyester fiber A and woven into a primary fabric. The primary fabric undergoes a water-soluble process to dissolve the vinylon fiber, leaving only ramie fiber B2 and iterative polyester fiber A in the fabric. Furthermore, since the vinylon in fiber B is dissolved, a large amount of space is left for the remaining ramie fiber B2, causing the ramie fiber to form a mesh structure, appearing fluffy, and significantly increasing the contact area with air.

[0035] As can be seen from the above manufacturing method, the basic characteristics of the finished fabric are: ① The fabric is woven from highly moisture-wicking polyester fibers and ramie fibers; ② The ramie fibers in the fabric are in a fluffy state.

[0036] When the finished fabric comes into contact with liquid, both iterated polyester fiber A and ramie fiber B2 exhibit hygroscopic properties, spreading the liquid over a larger area of ​​the fabric. However, in terms of hygroscopic performance, iterated polyester fiber A is superior to ramie fiber B2, playing a dominant role in spreading the liquid across the fabric. Due to ramie's superior water-draining properties, ramie fiber B2 more easily releases liquid molecules into the air during the competition between the fabric and the air. Therefore, liquid molecules diffused into the fabric are more easily released from the surface of ramie fiber B2 into the air. Furthermore, the fluffy nature of ramie fiber B2 provides a larger contact area with the air. This enhances the ability of liquid molecules to disperse from the surface of ramie fiber B2 into the air. In other words, ramie fiber B2 plays a dominant role in the diffusion of liquid from the fabric into the air. During this process, due to the higher moisture-wicking properties of the iterated polyester material currently available in the industry, it can diffuse the liquid over a larger area of ​​the fabric compared to other spinnable materials. Therefore, iterated polyester fiber A dominates the diffusion of liquid from the fabric into the air, providing conditions for a higher evaporation rate for ramie fiber B2 (the instantaneous evaporation rate of fibers or fabrics varies under different humidity conditions), resulting in a higher evaporation rate for the fabric.

[0037] Since the moisture-wicking capacity of fibers in a fabric is related to the humidity at the distal end of the fiber, that is, within the moisture-wicking distance, the greater the humidity difference between the two ends of the fiber, the stronger the moisture-wicking capacity of the fiber. Therefore, this embodiment utilizes the high moisture-wicking properties of iterated polyester to not only uniformly diffuse liquid to a larger area of ​​the fabric, but also, after the fluffy ramie fiber B2 releases liquid molecules, the high moisture-wicking iterated polyester fiber A can promptly replenish the liquid to the ramie fiber B2, keeping the ramie fiber B2 continuously under humidity conditions with a high evaporation rate, thus dominating the liquid evaporation process of the fabric and improving the overall evaporation rate of the fabric.

[0038] After implementation of this embodiment, the evaporation rate of the fabric can be significantly improved by using relatively conventional materials and conventional technical processes, with an evaporation rate increase of more than 30% compared to the Guinness World Record of the prior art. Figure 1 , Figure 2 This is the actual test report of the fabric after the implementation of this embodiment, wherein... Figure 2 The test results show that, according to the national standard GB / T 21655.1-2008 Evaluation of the moisture absorption and quick-drying properties of textiles - Part 1 - Single-item combination test method, the evaporation rate of the submitted fabric was 0.56 g / h before washing and 0.58 g / h after washing.

[0039] Since the fabric underwent pre-wash and post-wash tests during the inspection, and the results showed minimal difference, the possibility of the submitted fabric being chemically treated to obtain fraudulent test results can be completely ruled out. This confirms that after implementing this embodiment, the fabric's evaporation rate is 31.8% higher than the current Guinness World Record value of 0.44 g / h. Given that the current state of technological development in this field is largely limited to 0.44 g / h, the technology of this application, with its implementation results, possesses significant value.

[0040] Example 2 – Manufacturing high-evaporation-rate functional fabrics using the parallel-ply weaving-then-solvent method Backup materials: ① Iterative polyester made using the technology described in patents 201310420953.9 and 201110225265.8; ② Ramie; ③ Vinylon; Manufacturing methods include: High moisture-wicking fiber manufacturing process: The iterative polyester material is made into fibers, and after stretching and / or texturing processes, fiber A is produced; The process of making high moisture-release fiber: Water-soluble vinylon and ramie are made into fiber B1 and fiber B2 respectively, and then fiber B1 and fiber B2 are blended into fiber B through a spinning process. Blended fiber manufacturing process: Fiber B and fiber A are processed by core-sizing or doubling to produce blended fiber C; Primary fabric manufacturing process: using blended fiber C, the primary fabric is woven through a weaving process. Secondary fabric manufacturing process: Place the primary fabric in hot water, heat it to about 100°C, and make the water flow or make the primary fabric sway in the water to accelerate the dissolution process until fiber B1 in fiber B dissolves in the water. At this point, the secondary fabric is made. Finished fabric manufacturing process: The secondary fabric is washed, dried and smoothed to form the finished fabric.

[0041] The difference between this embodiment and Embodiment 1 is that Embodiment 1 uses fibers B and A to directly weave fabric, while this embodiment uses fibers B and A to form a blended fiber C through a core-spun or doubling process, which is then woven into fabric. Therefore, compared to Embodiment 1, the contact surface between fibers B and A in Embodiment 1 is the intersection point of the two fabrics (fibers B and A are used as warp and weft threads respectively), or the contact surface between adjacent warp and weft threads (fibers B and A are used as both warp and weft threads); while in this embodiment, fibers B and A exist in the form of doubling or core-spun yarns, and their contact area is much larger than in Embodiment 1. After the fabric comes into contact with liquid, the highly moisture-wicking iterative polyester fiber A can replenish the ramie fiber B2 with more liquid in a timely manner, allowing the ramie fiber B2 to maintain a higher evaporation rate humidity condition, thus enabling the fabric to achieve a higher evaporation rate.

[0042] Example 3 – Manufacturing high-evaporation-rate functional fabrics using discrete weaving method Backup materials: ① Iterative polyester made using the technology described in patents 201310420953.9 and 201110225265.8; ② Ramie; Manufacturing methods include: High moisture-wicking fiber manufacturing process: The iterative polyester material is made into fibers, and after stretching and / or texturing processes, fiber A is produced; Process for manufacturing high moisture release fiber: ramie short fibers are spun into fiber B using a spinning process; Fabric manufacturing process: Fiber A and fiber B are woven into fabric using a weaving process.

[0043] Compared to Examples 1 and 2, this example eliminates the need for water-soluble materials in fiber B, thus omitting the water-soluble process for the primary fabric and significantly reducing manufacturing costs. However, since ramie fiber B lacks the fluffiness of Examples 1 and 2, its contact area with air is obviously less than that of Examples 1 and 2. Therefore, the cost of this example is lower than that of Examples 1 and 2, but the evaporation rate is also lower. However, since it still adopts the technical concept of combining high moisture-wicking fibers and high moisture-releasing fibers in this application, and utilizes the advantages of each type of fiber in different processes, the fabric can still have a high evaporation rate. In applications where the evaporation rate requirement is slightly lower and cost is more sensitive, this example has a better market competitive advantage.

[0044] Example 4 – Manufacturing high-evaporation-rate functional fabrics using a ply-twisting weaving method Backup materials: ① Iterative polyester made using the technology described in patents 201310420953.9 and 201110225265.8; ② Ramie; Manufacturing methods include: High moisture-wicking fiber manufacturing process: The iterative polyester material is made into fibers, and after stretching and / or texturing processes, fiber A is produced; Process for manufacturing high moisture release fiber: ramie short fibers are spun into fiber B using a spinning process; Blended fiber manufacturing process: Fiber B and fiber A are processed by core-sizing or doubling to produce blended fiber C; Fabric manufacturing process: Fiber C is used to weave the fabric using a weaving process.

[0045] The difference between this embodiment and embodiment 3 is that embodiment 3 directly uses fiber A and fiber B to weave fabric, while this embodiment uses core-spun or doubling processes to "merge" fiber A and fiber B into "ply" fibers before weaving fabric.

[0046] Obviously, compared with Example 3, the fabric woven in this example has a larger contact area between the highly moisture-wicking fiber A and the highly moisture-releasing fiber B. The highly moisture-wicking fiber A is more efficient at transferring liquid to the fiber B, which makes the evaporation rate of the fabric higher than that in Example 3.

[0047] This embodiment adds a core-sleeving or twinning process, allowing the highly moisture-wicking fiber A and the highly moisture-releasing fiber B to come into closer contact. Compared to embodiment 3, the manufacturing process cost is increased, and the evaporation rate is also increased. This provides an option for market demands where cost investment and performance requirements are fluctuating, which is conducive to increasing market share.
