Description

Technical Field

[0001] This application relates to the field of textile fabric technology, and in particular to a method for preparing a fabric, the fabric itself, and clothing. Background Technology

[0002] Currently, most mainstream moisture-wicking fabrics work on the principle of absorption-diffusion-evaporation. Sweat is absorbed by the fabric and diffuses outwards, eventually being expelled through evaporation. However, in hot and humid environments or during strenuous exercise with heavy sweating, the evaporation rate decreases, causing the fabric to become heavily soaked and adhere to the skin, creating a sticky and stuffy feeling. Simultaneously, the salt and metabolic waste in the sweat remain in the fabric after evaporation, easily leading to sweat stains and odor.

[0003] To address these issues, related technologies have proposed directional sweat-wicking fabrics. These fabrics utilize a double-layer structure with a hydrophobic inner layer and a hydrophilic outer layer, employing capillary effects to conduct sweat from the skin to the outer surface of the fabric for evaporation. However, the double-layer structure inevitably increases the fabric's thickness and weight, contradicting the lightweight requirements of sportswear. Furthermore, sweat still lacks directional control on the fabric surface, easily spreading outwards and resulting in limited sweat-wicking efficiency. Summary of the Invention

[0004] One objective of this application is to provide a method for preparing a fabric, the fabric itself, and clothing, which aims to solve the technical problem that existing moisture-wicking fabrics are prone to becoming soaked and clinging to the body under high temperature and humidity or strenuous exercise conditions.

[0005] To achieve the above objectives, in a first aspect, this application provides a method for preparing a fabric, comprising: forming a fabric including a hydrophilic region and a hydrophobic region, wherein the hydrophilic region is shaped like a first strip and the hydrophobic region is shaped like a second strip, and the hydrophilic region and the hydrophobic region are alternately arranged in a direction perpendicular to their respective extension directions, for the purpose of diverting liquid from the hydrophobic region to the hydrophilic region.

[0006] This application utilizes the difference in wettability between hydrophilic and hydrophobic regions arranged in alternating bands on the same fabric. When liquid, especially sweat, falls onto the surface of the hydrophobic region, it does not spread and wet the hydrophobic region due to the repulsive effect of the hydrophobic region. Instead, driven by the wettability gradient, the liquid migrates towards the adjacent hydrophilic region perpendicular to its extension direction. After entering the hydrophilic region, the liquid is captured by the hydrophilic region due to its strong affinity and capillary adsorption capacity. Driven by gravity, capillary action, and other factors, the liquid is directionally transported along its extension direction. Thus, the hydrophobic region acts as a collector and guide, while the hydrophilic region acts as an absorber and directionally transporter. Together, they achieve the transformation of liquid from disordered planar diffusion to banded directional flow.

[0007] Compared to existing fabrics that rely on a moisture absorption-diffusion-evaporation pattern, the fabric of this application provides a clear directionality for liquid flow through the alternating arrangement of hydrophilic and hydrophobic regions, avoiding the problem of large-area soaking and clinging to the body caused by disordered spread of sweat on the fabric surface. Compared to the existing double-layer moisture-wicking structure with an inner hydrophobic layer and an outer hydrophilic layer, this application can achieve directional flow of liquid within the plane of a single layer of fabric without increasing the number of fabric layers, which is beneficial to reducing the thickness and weight of the fabric and meeting the lightweight requirements of sportswear.

[0008] In conjunction with the first aspect, according to one embodiment of this application, a fabric comprising a hydrophilic region and a hydrophobic region is formed, including:

[0009] Provide base fabric; A waterproof layer is applied to the surface of the base fabric. The area of ​​the base fabric covered by the waterproof layer forms a hydrophobic zone, while the area of ​​the base fabric not covered by the waterproof layer forms a hydrophilic zone.

[0010] A waterproof layer is set on the surface of the base fabric, so that the waterproof layer protrudes from the surface of the hydrophilic area. When the fabric is worn, if the waterproof layer faces the user's body, the wet hydrophilic area will naturally be separated from the skin by a certain gap, avoiding the discomfort of large pieces of fabric sticking to the body surface.

[0011] In conjunction with the first aspect, according to one embodiment of this application, a waterproof layer is provided on the surface of the base fabric, comprising: A waterproof layer is obtained by printing waterproof material on the base fabric surface; The waterproof material is a fluorine-free water-repellent additive; and / or, the thickness of the waterproof layer is 300-500 μm; and / or, the printing pressure is 0.3-0.5 MPa.

[0012] By printing waterproof material onto the base fabric surface to create a waterproof layer, the pattern shape and distribution of the hydrophobic areas can be precisely controlled, offering high process flexibility. Using a fluorine-free water-repellent additive as the waterproof material provides excellent water repellency to the hydrophobic areas while avoiding the environmental pollution problems that may arise from the production and use of fluorine-containing additives, thus meeting environmental protection requirements. Controlling the thickness of the waterproof layer within the range of 300–500 μm ensures good isolation of the hydrophilic areas from the wearer's skin during wear without forming noticeable ridges. Controlling the printing pressure within the range of 0.3–0.5 MPa facilitates partial penetration of the waterproof material into the fiber gaps of the base fabric surface, forming a uniformly thick waterproof layer. This avoids insufficient pressure leading to poor adhesion or uneven thickness, and excessive pressure causing over-penetration of the waterproof material, which could affect the hydrophilic properties of the hydrophilic areas.

[0013] In conjunction with the first aspect, according to one embodiment of this application, the method further includes: drying and curing the waterproof layer at 150-170°C for 2-5 minutes.

[0014] In conjunction with the first aspect, according to one embodiment of this application, a fabric comprising a hydrophilic region and a hydrophobic region is formed, including: The hydrophilic zone is formed by weaving with hydrophilic fibers; Hydrophobic areas are formed by weaving hydrophobic fibers; Among them, the water contact angle of hydrophilic fibers is smaller than that of hydrophobic fibers.

[0015] By weaving hydrophilic and hydrophobic fibers to form hydrophilic and hydrophobic zones respectively, the difference in wettability between the hydrophilic and hydrophobic zones is determined by the properties of the fiber materials themselves, which can be achieved without additional finishing processes, resulting in good washability and durability of the fabric.

[0016] In conjunction with the first aspect, according to one embodiment of this application, the denier number of the hydrophobic fiber is greater than that of the hydrophilic fiber, causing the surface of the hydrophobic region to protrude relative to the surface of the hydrophilic region.

[0017] By making the denier number of hydrophobic fibers greater than that of hydrophilic fibers, the monofilament diameter of the hydrophobic fibers is larger. The hydrophobic areas formed by weaving naturally protrude on the fabric surface, making the surface of the hydrophobic areas stand out relative to the surface of the hydrophilic areas. This creates a height difference between the hydrophobic and hydrophilic areas, allowing the wet hydrophilic areas to naturally separate from the skin during wear, avoiding the discomfort of large pieces of fabric sticking to the body.

[0018] In conjunction with the first aspect, according to one embodiment of this application, the ratio of the denier number of the hydrophilic fiber to the denier number of the hydrophobic fiber is 1:1.5 to 1:3.0; And / or, the denier numbers of both hydrophilic and hydrophobic fibers are between 20D and 100D.

[0019] To achieve the above objectives, in a second aspect, this application provides a fabric prepared using any of the methods described above.

[0020] To achieve the above objectives, in a third aspect, this application provides a fabric including a hydrophilic region and a hydrophobic region, wherein the hydrophilic region is shaped like a first strip and the hydrophobic region is shaped like a second strip, and the hydrophilic region and the hydrophobic region are alternately arranged in a direction perpendicular to their respective extension directions, for the purpose of diverting liquid from the hydrophobic region to the hydrophilic region.

[0021] To achieve the above objectives, in a fourth aspect, this application provides an garment comprising the fabric of the second or third aspect.

[0022] In conjunction with the fourth aspect, according to one embodiment of this application, when the clothing is worn, the hydrophilic area extends in the vertical direction and gradually narrows along the direction of gravity.

[0023] By extending the hydrophilic zone vertically when the garment is worn, the liquid absorbed by the hydrophilic zone can flow downwards along the extension direction of the zone under the influence of gravity, achieving gravity-assisted directional transport of the liquid and accelerating its discharge towards the hem of the fabric, thus reducing the liquid's residence time in the fabric. By gradually narrowing the hydrophilic zone in the direction of gravity, the cross-sectional area of ​​the hydrophilic zone gradually decreases along the liquid flow direction. According to the principle of fluid continuity, the liquid velocity increases in the narrowed section, thereby accelerating the liquid's discharge. Simultaneously, the narrowed structure concentrates the liquid into a narrower channel, further improving the liquid's aggregation effect, which is beneficial for the concentrated discharge or rapid evaporation of the liquid at the hem of the fabric.

[0024] The beneficial effects of aspects two through four above can be referred to in the first aspect or any possible implementation of the first aspect, and will not be elaborated here. Based on the implementations provided in the above aspects, this application can also be further combined to provide more implementations.

[0025] Other advantages, objectives and features of this application will be partly apparent from the description below, and partly understood by those skilled in the art through study and practice of this application. Attached Figure Description

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] Currently, most mainstream moisture-wicking fabrics work on the principle of absorption-diffusion-evaporation. Sweat is absorbed by the fabric and diffuses outwards, eventually being expelled through evaporation. However, in hot and humid environments or during strenuous exercise with heavy sweating, the evaporation rate decreases, causing the fabric to become heavily soaked and adhere to the skin, creating a sticky and stuffy feeling. Simultaneously, the salt and metabolic waste in the sweat remain in the fabric after evaporation, easily leading to sweat stains and odor.

[0031] To address these issues, existing technologies have proposed a unidirectional moisture-wicking solution. This solution utilizes a double-layer structure with a hydrophobic inner layer and a hydrophilic outer layer, leveraging capillary action to conduct sweat from the skin to the outer surface of the fabric for evaporation. This approach has significantly improved the problem of traditional fabrics sticking to the skin after absorbing moisture, making it the mainstream unidirectional moisture-wicking solution in the current sportswear industry.

[0032] However, the double-layered fabric structure inevitably increases the fabric's thickness and weight, leading to decreased breathability and increased workload during exercise. This contradicts the need for lightweight and comfortable sportswear, especially in scenarios requiring ultra-lightweight movement, such as summer clothing, underwear, and yoga / running gear. The bulkiness of traditional one-way moisture-wicking fabrics is particularly pronounced in these situations. Furthermore, sweat still lacks directional control on the fabric surface, tending to spread outwards and limiting its wicking efficiency.

[0033] To solve the above technical problems, firstly, please refer to... Figure 1 This application provides a method for preparing a fabric, comprising: forming a fabric including a hydrophilic region 10 and a hydrophobic region 20, wherein the hydrophilic region 10 is shaped as a first strip and the hydrophobic region 20 is shaped as a second strip, and the hydrophilic region 10 and the hydrophobic region 20 are alternately arranged in a direction perpendicular to their respective extension directions for the purpose of allowing liquid to flow from the hydrophobic region 20 to the hydrophilic region 10.

[0034] This application utilizes the difference in wettability between hydrophilic regions 10 and hydrophobic regions 20 arranged in alternating bands on the same fabric. When liquid, especially sweat, falls onto the surface of the hydrophobic region 20, it does not spread and wet the region due to the repulsive effect of the region. Instead, driven by the wettability gradient, the liquid migrates towards the adjacent hydrophilic region 10 perpendicular to its extension direction. After entering the hydrophilic region 10, the liquid is captured by the region due to its strong affinity and capillary adsorption capacity. Driven by gravity, capillary action, and other factors, the liquid is directionally transported along its extension direction. Thus, the hydrophobic region 20 acts as a collector and guide, while the hydrophilic region 10 acts as an absorber and directionally transporter. Together, they achieve the transformation of liquid from planar disordered diffusion to banded directional flow.

[0035] Compared with existing fabrics that rely on a moisture absorption-diffusion-evaporation pattern, the fabric of this application gives the liquid a clear direction of flow through the alternating arrangement of hydrophilic region 10 and hydrophobic region 20, avoiding the problem of large-area soaking and clinging to the body caused by disordered spread of sweat on the fabric surface. Compared with the existing double-layer moisture-wicking structure with an inner hydrophobic layer and an outer hydrophilic layer, this application can achieve directional flow of liquid in the plane of a single layer of fabric without increasing the number of fabric layers, which is conducive to reducing the thickness and weight of the fabric and meeting the lightweight requirements of sportswear.

[0036] It should be noted that, in the preferred wearing state, the hydrophilic region 10 extends vertically, thereby allowing the liquid to flow directionally from top to bottom along the extension direction of the hydrophilic region 10 under the assistance of gravity within the hydrophilic region 10, and finally collect and drain at the bottom of the fabric. In the following description of embodiments, unless otherwise stated, this preferred direction is used as an example.

[0037] In conjunction with the first aspect, please refer to Figure 2 According to one embodiment of this application, a fabric comprising a hydrophilic region 10 and a hydrophobic region 20 is formed, comprising: Provide base fabric 30; A waterproof layer 40 is provided on the surface of the base fabric 30. The area of ​​the base fabric 30 covered by the waterproof layer 40 forms a hydrophobic area 20, and the area of ​​the base fabric 30 not covered by the waterproof layer 40 forms a hydrophilic area 10.

[0038] A waterproof layer 40 is provided on the surface of the base fabric 30, so that the waterproof layer 40 protrudes from the surface of the hydrophilic area 10. During the wearing of the fabric, if the waterproof layer 40 faces the user's body, the wet hydrophilic area 10 will naturally be separated from the skin by a certain gap, avoiding the discomfort of a large area of ​​fabric adhering to the skin. It should be understood that this application isolates the hydrophilic area 10 from the skin by protruding the waterproof layer 40. Although it is unavoidable that the waterproof layer 40 comes into contact with the skin during actual wear, since the hydrophilic area 10 is the area that is wet after absorbing liquid, while the waterproof layer 40 itself does not absorb or absorbs very little liquid, the wearer's comfort is significantly improved compared to the situation where traditional fabrics adhere to the skin surface after large areas become wet. In other words, the wet hydrophilic area 10 is separated by the waterproof layer 40 and will not stick to the skin surface. During exercise, the hydrophobic area 20 can also be easily separated from the skin surface.

[0039] It should be noted that the formation of a waterproof layer 40 on the surface of the base fabric 30 does not mean that the waterproof material is only present on the outermost surface of the base fabric 30. The waterproof material can also partially penetrate into the gaps between the surface fibers of the base fabric 30, as long as a continuous waterproof layer 40 is formed on the surface of the base fabric 30 and the waterproof layer 40 protrudes from the surface of the hydrophilic region 10. The scope of protection of this application should not be limited based on the presence or distribution of waterproof material within the base fabric 30.

[0040] It should also be noted that although the base fabric 30 under the waterproof layer 40 still has a certain water absorption capacity, in actual application, the hydrophobic area 20 will not have the same liquid guiding effect as the hydrophilic area 10. The reasons are at least as follows: First, the base fabric 30 absorbs some waterproof material during the process of setting the waterproof layer 40, which reduces the water absorption of this part of the base fabric 30. The conduction of liquid from the hydrophilic area 10 to the hydrophobic area 20 is not as smooth as the conduction inside the hydrophilic area 10. Second, in actual wear, the liquid is mainly affected by gravity and is transmitted within the hydrophilic area 10 along the extension direction of the hydrophilic area 10. The lateral migration from the hydrophilic area 10 to the hydrophobic area 20 relies only on the capillary phenomenon of the fiber itself. The driving force is much smaller than gravity. Therefore, the liquid preferentially flows longitudinally along the hydrophilic area 10 rather than diffuses laterally to the hydrophobic area 20.

[0041] In conjunction with the first aspect, according to one embodiment of this application, a waterproof layer 40 is provided on the surface of the base fabric 30, comprising: A waterproof layer 40 is obtained by printing a waterproof material on the surface of the base fabric 30. The waterproof material is a fluorine-free water-repellent additive; and / or, the thickness of the waterproof layer 40 is 300-500 μm; and / or, the printing pressure is 0.3-0.5 MPa.

[0042] For example, the thickness of the waterproof layer 40 can be 300μm, 350μm, 400μm, 450μm or 500μm. For example, the printing pressure can be 0.3MPa, 0.35MPa, 0.4MPa, 0.45MPa or 0.5MPa.

[0043] By printing waterproof material onto the surface of the base fabric 30, the waterproof layer 40 can be precisely controlled in terms of pattern shape and distribution of the hydrophobic areas 20, offering high process flexibility. Using a fluorine-free water-repellent additive as the waterproof material provides excellent water repellency to the hydrophobic areas 20 while avoiding the environmental pollution problems that may arise from the production and use of fluorine-containing additives, thus meeting environmental protection requirements. Controlling the thickness of the waterproof layer 40 within the range of 300–500 μm ensures good isolation of the hydrophilic areas 10 from the wearer's skin during wear, without forming noticeable ridges. Controlling the printing pressure within the range of 0.3–0.5 MPa facilitates partial penetration of the waterproof material into the fiber gaps of the base fabric 30, forming a uniformly thick waterproof layer 40. This avoids situations where excessively low pressure leads to poor adhesion or uneven thickness of the waterproof layer 40, or excessive pressure causes over-penetration of the waterproof material, affecting the hydrophilic properties of the hydrophilic areas 10.

[0044] It should be noted that the thickness of the waterproof layer 40 is not intended to completely prevent the hydrophilic area 10 from contacting the skin. Its function is that the waterproof layer 40 protrudes from the surface of the hydrophilic area 10 with this thickness, so that at least the part of the hydrophilic area 10 adjacent to both sides of the waterproof layer 40 forms a gap with the skin. In motion, this gap breaks the surface tension between the originally large area of ​​the wet fabric and the skin, so that the hydrophilic area 10 can be separated from the skin more easily with the wearer's movement, thereby significantly improving the discomfort caused by wet clothing against the skin.

[0045] In conjunction with the first aspect, according to one embodiment of this application, the method further includes: drying and curing the waterproof layer 40 at 150-170°C for 2-5 minutes.

[0046] For example, the drying and curing temperature can be 150°C, 155°C, 160°C, 165°C, or 170°C. For example, the drying and curing time can be 2 minutes, 3 minutes, 4 minutes, or 5 minutes.

[0047] By drying and curing the waterproof layer 40 at 150–170℃, the waterproof material undergoes a cross-linking reaction on the surface of the base fabric 30, improving the bonding strength between the waterproof layer 40 and the base fabric 30. This ensures that the waterproof layer 40 is not easily detached during repeated washing and wearing, thus maintaining the long-term water-repellent performance of the hydrophobic region 20. Controlling the curing time to 2–5 minutes ensures sufficient cross-linking and curing of the waterproof material while avoiding thermal damage to the fibers of the base fabric 30 caused by excessively long-term high-temperature treatment.

[0048] In conjunction with the first aspect, according to one embodiment of this application, please refer to Figure 3 This forms a fabric comprising a hydrophilic region 10 and a hydrophobic region 20, including: Hydrophilic fibers are used to weave together to form a hydrophilic zone 10; Hydrophobic areas 20 are formed by weaving hydrophobic fibers; Among them, the water contact angle of hydrophilic fibers is smaller than that of hydrophobic fibers.

[0049] The hydrophilic region 10 and the hydrophobic region 20 are formed by weaving hydrophilic and hydrophobic fibers respectively. The difference in wettability between the hydrophilic region 10 and the hydrophobic region 20 is determined by the properties of the fiber material itself and can be achieved without additional finishing processing. The fabric has good washability and durability.

[0050] For example, hydrophilic fibers may include, but are not limited to, polyester or nylon filaments with irregular cross-sections, such as cross-sections, Y-shaped cross-sections, and star-shaped cross-sections. The irregular cross-section structure increases the specific surface area of ​​the fiber, which is beneficial for enhancing capillary effects, thereby improving the absorption and conduction capacity of the hydrophilic region 10 for liquids. Hydrophobic fibers may include, but are not limited to, water-repellent modified polyester, water-repellent modified nylon, polypropylene, etc., such as modified fibers prepared by copolymerization or blending.

[0051] Furthermore, to optimize the conduction efficiency of liquid within the hydrophilic zone 10 along its extension direction, the weaving process can employ either warp knitting jacquard or weft knitting. When using warp knitting jacquard, the fibers move loops along the warp direction, and the extension direction of the hydrophilic zone 10 aligns with the fabric's weaving direction. The fiber orientation within the hydrophilic zone 10 is also consistent with its extension direction, allowing the liquid to flow smoothly along the fiber direction after absorption by the hydrophilic zone 10. When using weft knitting, the fibers form loops along the weft direction. The fiber orientation within the hydrophilic zone 10 remains consistent with its extension direction, but the extension direction of the hydrophilic zone 10 is perpendicular to the fabric's weaving direction. Therefore, when cutting the garment, the fabric needs to be rotated 90 degrees to convert the extension direction of the hydrophilic zone 10 into the garment's longitudinal direction, allowing the liquid to flow smoothly along the extension direction of the hydrophilic zone 10 while worn.

[0052] In conjunction with the first aspect, according to one embodiment of this application, the denier number of the hydrophobic fiber is greater than that of the hydrophilic fiber, causing the surface of the hydrophobic region 20 to protrude relative to the surface of the hydrophilic region 10.

[0053] By making the denier number of the hydrophobic fiber greater than that of the hydrophilic fiber, the monofilament diameter of the hydrophobic fiber is thicker. The hydrophobic region 20 formed by weaving naturally forms a protrusion on the fabric surface, making the surface of the hydrophobic region 20 protrude relative to the surface of the hydrophilic region 10. As a result, a height difference is formed between the hydrophobic region 20 and the hydrophilic region 10. During the wearing process, the wet hydrophilic region 10 is naturally separated from the skin by a certain gap, avoiding the discomfort of large areas of fabric adhering to the body surface.

[0054] In conjunction with the first aspect, according to one embodiment of this application, the ratio of the denier number of the hydrophilic fiber to the denier number of the hydrophobic fiber is 1:1.5 to 1:3.0; And / or, the denier numbers of both hydrophilic and hydrophobic fibers are between 20D and 100D.

[0055] For example, the ratio of the denier number of the hydrophilic fiber to that of the hydrophobic fiber can be 1:1.5, 1:2.0, 1:2.5, or 1:3.0. For example, the denier number of the hydrophilic fiber can be 20D, 30D, 40D, 50D, or 100D; the denier number of the hydrophobic fiber can be 20D, 40D, 60D, 80D, or 100D.

[0056] By controlling the denier ratio of hydrophilic fibers to hydrophobic fibers within the range of 1:1.5 to 1:3.0, it ensures that the hydrophobic region 20 has sufficient height relative to the hydrophilic region 10 to form an effective physical barrier and isolation gap, while avoiding excessive denier difference that would cause overly noticeable protrusions on the fabric surface, affecting wearing comfort and appearance smoothness. Controlling the denier of both hydrophilic and hydrophobic fibers between 20D and 100D helps maintain a lightweight and soft feel in the fabric, meeting the lightweight requirements of sportswear.

[0057] To address the aforementioned technical problems, in a second aspect, this application provides a fabric prepared using the method disclosed in any of the above embodiments.

[0058] The fabric of the second aspect is prepared by the method of the first aspect, and its beneficial effects are described in accordance with the first aspect or any possible implementation method of the first aspect, which will not be elaborated here.

[0059] To solve the above-mentioned technical problems, in a third aspect, this application provides a fabric including a hydrophilic region 10 and a hydrophobic region 20. The hydrophilic region 10 is shaped like a first strip, and the hydrophobic region 20 is shaped like a second strip. The hydrophilic region 10 and the hydrophobic region 20 are arranged alternately in their respective vertical extension directions to allow liquid to flow from the hydrophobic region 20 to the hydrophilic region 10.

[0060] To solve the above-mentioned technical problems, in a fourth aspect, this application provides an garment, including the fabric of the second or third aspect.

[0061] By applying the above-mentioned fabric to clothing, the clothing is equipped with the function of directional liquid flow and drainage. When the wearer sweats during exercise, the sweat can flow and drain in a directional manner along the hydrophilic zone 10, keeping the wearer's skin surface relatively dry and improving wearing comfort.

[0062] In conjunction with the fourth aspect, please refer to Figure 4 According to one embodiment of this application, when the clothing is worn, the hydrophilic area 10 extends vertically and gradually narrows along the direction of gravity. It should be understood that the narrowing here refers to the reduction in the size of the hydrophilic area 10 in the direction perpendicular to its extension.

[0063] By extending the hydrophilic zone 10 vertically when the garment is worn, the liquid absorbed by the hydrophilic zone 10 can flow from top to bottom along the extension direction of the hydrophilic zone 10 under the action of gravity, realizing gravity-assisted directional transport of the liquid, accelerating the discharge of the liquid towards the hem of the fabric, and reducing the residence time of the liquid in the fabric. By gradually narrowing the hydrophilic zone 10 in the direction of gravity, the cross-sectional area of ​​the hydrophilic zone 10 gradually decreases along the direction of liquid flow. According to the principle of fluid continuity, the flow velocity of the liquid increases in the narrow section, thereby accelerating the discharge of the liquid. At the same time, the narrowing structure concentrates the liquid into a narrower channel, further improving the liquid convergence effect, which is conducive to the concentrated discharge or rapid evaporation of the liquid at the hem of the fabric.

[0064] The beneficial effects of the second to fourth aspects above can be referred to the first aspect or any possible implementation of the first aspect. Based on the implementations provided in the above aspects, this application can also make further combinations to provide more implementations.

[0065] It should be noted that the order of description of the embodiments in this application is not intended to limit the priority of the embodiments.

[0066] The technical solution of this application will be further described below through specific embodiments.

[0067] Example 1 (Weaving - Warp Knitting - Funnel Pattern) Cross-section nylon filaments with a denier of 40D were selected as the hydrophilic fiber, and their moisture absorption and quick-drying properties met the GB / T 21655.1-2023 Class II standard. Water-repellent nylon prepared by blending was selected as the hydrophobic fiber with a denier of 60D (hydrophilic to hydrophobic fiber denier ratio of 1:1.5), and its water-repellent properties met the GB / T 4745-2012 Class 4 standard. A warp-knitted jacquard weave was used to form a funnel-shaped pattern. In the hydrophilic zone (10), the upper width of the funnel is 1cm and the lower width is 0.8cm; in the hydrophobic zone (20), the upper width of the funnel is 0.3cm and the lower width is 0.6cm. After weaving, dyeing and finishing treatments were performed. The resulting fabric has a weight of 152g / m².

[0068] Example 2 (Weaving - Weft Knitting - Striped Pattern) Y-section polyester filament with a denier of 40D was selected as the hydrophilic fiber, and its moisture absorption and quick-drying performance met the GB / T 21655.1-2023 Class II standard. Blended water-repellent modified polyester filament with a denier of 100D (hydrophilic to hydrophobic fiber denier ratio of 1:2.5) was selected as the hydrophobic fiber, and its water-repellent performance met the GB / T 4745-2012 Class 4 standard (water repellency score ≥90). A circular knitting machine was used to alternately knit the hydrophilic zone 10 and the hydrophobic zone 20 to form a striped pattern. The width of the hydrophilic zone 10 was 1.5cm, and the width of the hydrophobic zone 20 was 0.5cm. After knitting, dyeing and finishing treatments were performed. When cutting the garment, the fabric was used horizontally so that the hydrophilic zone 10 extended vertically when worn. The resulting fabric weight was 145g / m².

[0069] Example 3 (Printed Funnel Pattern) A knitted fabric made of nylon filaments with a cross-section (X-shaped) was selected as the base fabric 30. The base fabric 30 has a weight of 148 g / m², and its moisture-wicking performance meets GB / T 21655.1-2023 Level II. A funnel-shaped printed pattern was designed. The upper width of the funnel in the hydrophilic zone 10 is 2 cm, and the lower width is 1.5 cm; the upper width of the funnel in the hydrophobic zone 20 is 0.6 cm, and the lower width is 1 cm. A printing process was used, applying a fluorine-free water-repellent agent to the hydrophobic zone 20. The printing pressure was controlled at 0.3–0.5 MPa, causing the water-repellent agent to form a micro-protrusion coating of approximately 300–500 μm on the fabric surface. After printing, it was dried and cured at 160℃ for 3 minutes. Testing showed that the water-repellent performance of the hydrophobic zone 20 meets GB / T 4745-2012 Level 4.

[0070] Example 4 (Printed - Striped Pattern) A knitted fabric made of cross-section polyester filament was selected as the base fabric 30, with a weight of 150 g / m². Its moisture absorption and quick-drying properties met the GB / T 21655.1-2023 Class II standard. A striped printed pattern was designed, with the hydrophilic zone 10 having a width of 1.8 cm and the hydrophobic zone 20 having a width of 0.6 cm. A printing process was employed, applying a fluorine-free water-repellent agent to the hydrophobic zone 20. The printing pressure was controlled at 0.3–0.5 MPa, causing the water-repellent agent to form a micro-raised coating of approximately 300–500 μm on the fabric surface. After printing, the fabric was dried and cured at 160℃ for 3 minutes. Testing showed that the water-repellent performance of the hydrophobic zone 20 met the GB / T 4745-2012 Class 4 standard.

[0071] Comparative Example 1 (No functional zones, no printing) The base fabric 30 is a knitted fabric made of polyester filaments with the same cross-section. The base fabric 30 has a weight of 150 g / m², and its moisture absorption and quick-drying performance has been tested and meets the GB / T 21655.1-2023 Class II level. No printing process is performed, and the fabric surface has no functional division between hydrophilic and hydrophobic areas.

[0072] Comparative Example 2 (Weaving - Weft Knitting - Striped Pattern: No Protrusions in Hydrophilic and Hydrophobic Areas) Y-section polyester filament with a denier of 40D was selected as the hydrophilic fiber, and its moisture absorption and quick-drying performance met the GB / T 21655.1-2023 Class II standard. Blended water-repellent modified polyester filament with a denier of 40D (hydrophilic to hydrophobic fiber denier ratio of 1:1) was selected as the hydrophobic fiber, and its water-repellent performance met the GB / T 4745-2012 Class 4 standard (water repellency score ≥ 90 points). A circular knitting machine was used to alternately knit the hydrophilic zone 10 and the hydrophobic zone 20 to form a striped pattern. The width of the hydrophilic zone 10 was 1.5cm, and the width of the hydrophobic zone 20 was 0.5cm. After knitting, dyeing and finishing treatments were performed. The resulting fabric had a weight of 125g / m².

[0073] Comparative Example 3 (Printed - Striped Pattern: The width of the hydrophilic area is smaller than the width of the hydrophobic area) A knitted fabric made of cross-section polyester filament was selected as the base fabric 30, with a weight of 150 g / m². Its moisture absorption and quick-drying properties met the GB / T 21655.1-2023 Class II standard. A striped printed pattern was designed, with the hydrophilic zone 10 having a width of 0.6 cm and the hydrophobic zone 20 having a width of 1.8 cm. A printing process was employed, applying a fluorine-free water-repellent agent to the hydrophobic zone 20. The printing pressure was controlled at 0.3–0.5 MPa, causing the water-repellent agent to form a micro-raised coating of approximately 300–500 μm on the fabric surface. After printing, the fabric was dried and cured at 160℃ for 3 minutes. Testing showed that the water-repellent performance of the hydrophobic zone 20 met the GB / T 4745-2012 Class 4 standard.

[0074] Performance testing: The following performance tests were performed on the fabrics of the above embodiments and comparative examples: Test samples for tests ① and ②: Prepare a 5cm × 30cm strip of fabric.

[0075] ①Speed ​​of sweat flowing downward along the hydrophilic zone 10: Hang the cloth strip vertically, add liquid water to the top of the hydrophilic zone 10, record the time required for the water front to move 20cm, and calculate the average moving speed.

[0076] ② Bottom sweat collection rate: Place a collector at the bottom of the fabric and add 30ml of liquid water to the top of the hydrophilic zone 10. Stop the test if no more liquid water is collected within 5 minutes after the last drop is collected. Accurately weigh the percentage of the collected liquid water to the total input weight.

[0077] ③ Fabric adhesion evaluation: The test was conducted in accordance with T / CNGA 64—2024 "Determination of wet adhesion of clothing".

[0078] Test results:

[0079] Results analysis: As shown in the table above, Examples 1 to 4 of this application, while maintaining a low weight (145 to 152 g / m²), achieve excellent sweat-wicking speed (0.45 to 0.52 cm / s), high bottom collection rate (62% to 68%), and good anti-sticking properties (15 to 20 cN), which are significantly better than the comparative examples.

[0080] Comparative Example 1 is a regular moisture-wicking and quick-drying fabric without functional zones or water-repellent printing treatment. After absorbing moisture, the fabric diffuses randomly in all directions and has no microscopic raised structure. Its sweat-wicking efficiency and anti-sticking performance are significantly reduced.

[0081] In Comparative Example 2, the hydrophilic and hydrophobic fibers have the same denier number, which prevents the formation of a surface protrusion in the hydrophobic region 20 relative to the hydrophilic region 10. As a result, the physical barrier function is lost, and the sweat-wicking efficiency and anti-stickiness performance are significantly reduced.

[0082] In Comparative Example 3, the width of the hydrophobic region 20 is greater than the width of the hydrophilic region 10, causing sweat to spread in the excessively wide hydrophobic region 20 and not be effectively captured by the hydrophilic region 10, resulting in a significant decrease in both sweat-wicking efficiency and anti-stickiness performance.
