Description

Technical Field

[0001] This utility model relates to the field of textiles. Specifically, it relates to a sweat-wicking, moisture-wicking, and quick-drying knitted fabric with sweat management function and clothing with sweat management function. Background Technology

[0002] With the development of sportswear trends, consumers are paying more attention to the comfort of clothing during exercise. This is especially true when sweating, particularly during intense competitions and sports where heavy sweating occurs. Therefore, there are increasing demands on aspects such as the moisture-wicking efficiency of clothing fabrics, the close-fitting comfort when sweating, and the feeling of dryness against the skin.

[0003] Currently, the main management theory for sweat control in sportswear materials relies on the fabric's absorbency, wicking of sweat from the inner layer to the outer layer, and the quick-drying of the outer layer. However, this approach has several limitations, such as being constrained by the fabric's absorbency, wicking capacity, and the quick-drying ability of the outer layer. In particular, under conditions of heavy sweating, the fabric easily reaches saturation, causing sweat to accumulate and increasing the contact area between the fabric and the skin. Due to surface tension, the sweat adheres to the skin, resulting in the sportswear clinging damply to the body. This is especially true for thinner fabrics, which have lower absorbency saturation and are more prone to sticking to the skin, causing discomfort and significantly impacting the feeling during exercise, even affecting athlete performance.

[0004] Therefore, providing a more efficient sweat management solution and developing new moisture-wicking and quick-drying knitted fabrics based on such a solution are urgent technical problems that need to be solved. Utility Model Content

[0005] To address the problems existing in the prior art, the inventors of this utility model comprehensively considered the evaporation of sweat under normal human conditions and the seepage of sweat from the skin during exercise.

[0008] The inner layer 2 has a sweat-wicking groove structure on its skin-contact surface. This sweat-wicking groove structure includes multiple longitudinally parallel strip-shaped protrusions 3, with grooves 4 formed between adjacent strip-shaped protrusions.

[0009] The strip-shaped protrusions 3 are woven from second hydrophobic fibers with irregular cross sections, and the grooves 4 form a channel for sweat and air circulation on the skin contact surface.

[0015] Preferably, the irregular cross section is selected from one of the following: triangular cross section, cross-shaped cross section, trefoil cross section, multi-leaf cross section, fan-shaped cross section, elliptical cross section, and star-shaped cross section.

[0019] Optionally, the hygroscopic fiber is a short fiber yarn or a filament yarn;

[0020] Preferably, the count of the short fiber yarn is 32S to 80S, more preferably 40S to 60S;

For example, the first and second hydrophobic fibers can be selected from polyester, polypropylene, and modified nylon hydrophobic fibers with irregular cross-sections, having a denier of 40D to 100D and a filament count of 12F to 144F.

[0027] It should be noted that the various materials used in this utility model, such as hygroscopic fibers, are all materials known in the prior art.

[0028] On the other hand, the present invention also provides a garment with a sweat management function, wherein at least a portion of the garment is made of the knitted fabric described in the present invention.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] (1) This utility model provides multiple strip-shaped protrusions on the skin-contacting surface of the inner layer of the knitted fabric, forming sweat-wicking grooves between adjacent strip-shaped protrusions. This creates a microcirculation between the fabric and the skin during wear, more effectively collecting and timely wicking away sweat, preventing excessive sweat accumulation, reducing the contact area between the material and the skin, thereby improving sweat management efficiency, preventing the fabric from sticking to the body, and ultimately improving the wearing experience.

[0031] (2) The knitted fabric of this utility model adopts a double-layer structure. The outer layer is made of hygroscopic fibers, which has good moisture absorption and high moisture regain. The inner layer is made of water-repellent material. Therefore, the knitted fabric will form a hydrophilic gradient difference of moisture, thus having the function of unidirectionally guiding moisture from the inner layer to the outer layer.

[0042] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0043] To facilitate understanding, some terms used in this utility model will be explained.

[0044] In this invention, the "inner layer" of the knitted fabric refers to the reverse side of the knitted fabric, which is close to the body during use. The "outer layer" of the knitted fabric refers to the front side of the knitted fabric, which is away from the body during use relative to the "inner layer".

[0045] In this invention, the "longitudinal direction" of the knitted fabric, also known as the "warp direction," refers to the direction in which the yarns are arranged along the length of the fabric.

[0046] In this invention, "monofilament number", also known as "F number", refers to the number of fine fibers in a yarn. For example, 100F means that the number of fibers that make up a yarn is 100.

[0047] In this invention, "count" refers to the length of 1 pound (453.6 grams) of yarn.

[0048] In this utility model, "denier", also known as "D number", refers to the weight (in grams) of 9000 meters of fiber or yarn at the standard moisture regain.

[0049] The moisture-wicking and quick-drying knitted fabric of this utility model will be described in detail below with reference to the accompanying drawings.

[0050] like Figure 1 and Figure 2 As shown, the moisture-wicking and quick-drying knitted fabric of this invention includes a surface layer 1 and an inner layer 2, which are connected to each other by knitting loops (not shown). The surface layer 1 is woven from moisture-wicking fibers, and the inner layer 2 is woven from a first hydrophobic fiber. A sweat-wicking groove structure is formed on the skin-contact surface of the inner layer 2. The sweat-wicking groove structure includes a plurality of longitudinally parallel strip-shaped protrusions 3, and grooves 4 are formed between adjacent strip-shaped protrusions.

[0051] This design reduces the contact area between the fabric and the skin. On one hand, these grooves allow sweat to wick away, preventing it from accumulating and causing discomfort. On the other hand, these grooves create numerous visible air channels between the fabric and the skin, accelerating the microcirculation of warm, humid air between the body and the fabric. This ensures smooth airflow during wear, providing structural support for keeping the body dry during exercise.

[0052] According to some embodiments of this utility model, the strip-shaped protrusion 3 is woven from a second hydrophobic fiber with an irregular cross-section. An irregular cross-section refers to a non-circular cross-section. Preferably, the second hydrophobic fiber used to prepare the strip-shaped protrusion 3 has one of the following cross-sections: triangular, cross-shaped, trefoil, multi-lobed, fan-shaped, elliptical, and star-shaped. More preferably, the irregular cross-section is a cross-shaped cross-section.

[0053] Furthermore, the second hydrophobic fiber used to prepare the strip-shaped protrusions 3 is selected from polyester, polypropylene, or hydrophobically modified chemical fiber filaments or yarns. Preferably, the number of monofilaments of the second hydrophobic fiber is configured to give it wicking and water-conducting capabilities.

[0054] More preferably, the F number of the second hydrophobic fiber is 12-144F, and particularly preferably, the F number of the second hydrophobic fiber is 12-72F.

[0055] Through research, the inventor discovered that by using a second hydrophobic fiber with an irregular cross-section to weave strip-shaped protrusions 3, more gaps can be created between the fibers, thus enriching the siphon channels and improving the wicking capacity.

[0056] By using high-filament yarn to weave the striped protrusions 3, the striped protrusions 3 become softer and more comfortable when in contact with the skin. Furthermore, the fibers in the protrusions are hydrophobic, allowing moisture to be drawn away to the surface of the fabric through a wicking effect, keeping the parts of the fabric in contact with the body dry and comfortable.

[0057] According to some embodiments of the present invention, the distance I between adjacent strip-shaped protrusions 3 is 1mm to 10mm, preferably 1mm to 3mm.

[0058] The width ratio (W / I) of the raised portion (the part in contact with the skin) to the space between the raised portions (the grooved portion, i.e., the part not in contact with the skin) should ideally be ≤2. This ensures that at least ≥30% of the fabric area is not in direct contact with the skin when in direct contact, creating a microcirculation space and a sweat-wicking groove. This effectively solves the problem of stickiness and improves sweat-wicking efficiency. Furthermore, depending on the type of fiber used in development, the fabric stiffness varies. Therefore, the width of the groove (i.e., the distance I between adjacent strip-shaped raised portions 3) should be ≤10mm to ensure the groove's effectiveness. Considering the stiffness of most clothing materials and the initial bead size of sweat when the body sweats, the groove width is preferably 1-3mm. As for the groove height (i.e., the height H of the raised portion), considering the contact with the skin and the shape of sweat, it is best to ensure it is between 0.2mm and 2mm to guarantee the effectiveness of the groove and sweat wicking (grooves that are too high will affect the comfort of wearing the garment).

[0059] By weaving strip-shaped protrusions with the above parameters along the longitudinal direction in the inner layer of the fabric, rapid and efficient sweat wicking and air circulation can be achieved.

[0060] First, when the fabric comes into contact with the skin, it is the raised part of the fabric that contacts the body. Even when completely wet, the contact area between the material and the body is less than 50%, and many gaps are left. This ensures that even when the body is sweating profusely, the sweat will not be absorbed by the fabric onto the skin due to surface tension, so that the fabric will not stick to the body even when the body is sweating profusely.

[0061] Secondly, when the amount of sweat produced by the body exceeds the saturation capacity of the fabric's absorbency, the fabric's groove structure will form grooves between the skin and the fabric, allowing sweat to flow down through these grooves and preventing it from accumulating too much and causing discomfort.

[0062] Secondly, the raised inner layer of the fabric comes into contact with the skin. During exercise, these grooves will move relative to the skin, thus promptly scraping away and draining the sweat, similar to many small towel strips, constantly wiping the body and collecting sweat from the skin.

[0063] In addition, the grooved design of the fabric creates many obvious air channels between the fabric and the skin, accelerating the microcirculation of hot and humid air between the body and the fabric. This ensures that the clothing maintains smooth airflow during wear, providing structural support for keeping the body dry during exercise.

[0064] According to some embodiments of this utility model, the hygroscopic fiber used for weaving the surface layer is a short fiber yarn or a filament yarn. Preferably, the count of the short fiber yarn is 32S to 80S; or, preferably, the count of the filament yarn is 40D to 100D and the fraction number is 36F to 144F.

[0065] The moisture-absorbing fibers used for the woven surface layer can be yarns known in the art, as long as they meet the above parameter requirements. For example, the moisture-absorbing fibers can be selected from cotton yarn, cotton blended yarn, viscose yarn, viscose blended yarn, nylon, and water-absorbing modified polyester.

[0066] The first hydrophobic fiber used for weaving the inner layer is a filament yarn. Preferably, the filament yarn has a denier of 40D to 100D and a filament count of 12F to 96F.

[0067] The first hydrophobic fiber used for weaving the inner layer can be any yarn known in the art, as long as it meets the above-mentioned parameter requirements. For example, the first hydrophobic fiber is selected from polyester, polypropylene, and modified hydrophobic nylon materials.

[0068] This invention's knitted fabric employs a yarn combination scheme where the surface layer fibers have good moisture absorption properties, while the inner layer fibers are hydrophobic. On one hand, the surface layer fibers utilize relatively good moisture absorption properties, forming a high moisture regain layer with a moisture regain ≥4.5% (using the standard moisture regain of ordinary nylon materials at room temperature). On the other hand, the inner layer fibers use water-repellent materials, allowing for better wicking away of sweat. The inner layer fibers have a moderate fiber number, giving them good wicking and moisture-conducting capabilities, effectively transferring sweat from the skin to the surface layer of the knitted fabric for rapid drying. Therefore, the double-layer structure of this invention's knitted fabric creates a hydrophilic gradient, enabling unidirectional moisture wicking from the inner layer to the surface layer.

[0069] According to some preferred embodiments of the present invention, the hygroscopic fiber used for weaving the outer layer is nylon yarn with a D number of 40D-100D and filament yarn with an F number of 36-72F; the first hydrophobic fiber used for weaving the inner layer is filament yarn with a D number of 50-75D and an F number of 12-72F.

[0070] For example, the hygroscopic fibers used for the outer layer can be: nylon yarn of 40D-100D; nylon filament yarn of F number 12F-72F; nylon yarn, cotton or T / C yarn of 32S-50S; or nylon yarn, cotton or T / R yarn of 32S-50S. The first hydrophobic fiber used for the inner layer can be: nylon yarn of 30D-100D; round-hole polyester filament yarn of F number 12F-72F; nylon yarn of 30D-100D; cross-cut polyester filament yarn of F number 12F-72F; polypropylene yarn of 30D-75D; or round-hole polyester filament yarn of F number 48F-72F.

[0071] The weaving method of the knitted fabric of this utility model can refer to relevant solutions in the prior art. For example, according to Figures 3 to 6 Weave according to the needle pattern shown.

[0072] The knitted fabric of this invention has moisture-wicking and quick-drying properties and can be used to produce various garments, such as sportswear.

[0073] During the cutting process, the longitudinal grooves of the fabric are cut along the vertical direction of the garment, ensuring that the direction of the grooves is perpendicular to the ground when the garment is made, thus effectively wicking away sweat quickly.

[0074] Example 1

[0075] In this embodiment, the surface layer uses 75D / 72F polyester yarn, accounting for 60% of the weight. The yarn uses high F-number fibers to increase the wicking capacity of the surface layer and the exposed area of ​​the fibers in the air, thereby improving the one-way moisture wicking ability and quick-drying ability.

[0076] The inner layer uses 75D / 36F cross-cut DTY yarn, accounting for 40% of the weight, giving the inner layer better sweat collection and wicking capabilities. The finished fabric weight is 150g / m². 2 The inner layer of the fabric features multiple parallel strip-shaped protrusions along the longitudinal direction. During weaving, the structural design of the fabric loop structure creates a distinct groove structure. The protrusions are 1mm wide, 1mm apart, and 0.2mm high.

[0077] The specific preparation process is as follows:

[0078] (1) Weaving: according to Figure 7The needle arrangement shown is used for knitting on a 34-inch double-sided knitting machine, and the knitting method is as follows:

[0079] The fabric is divided into 12 loops: the lining yarn is made of coldry, and the outer yarn is made of regular polyester. Loops 2-4-6-...-12 are the lining yarn, and loops 1-3-5-...-11 are the outer yarn. Each loop consists of 8 stitches of the upper needle. Upper needle A loops with lower needles A / C in loops 1-3-7-9, creating yarn traction and forming dots on the outer yarn surface to facilitate the wicking of sweat to the front. In loops 5 and 11, upper needle A loops separately, forming a separate horizontal line for better sweat evaporation. The upper needles follow this pattern thereafter. Similarly, each loop of the lower needle consists of 8 stitches. First, lower needles loop separately in loops B, C, A, B in loops 2-4-8-10, and then loop A, B, C in loops 6-12, which better absorbs sweat. Every three lower needles are skipped, forming breathable vertical stripes to create the greige fabric.

[0080] (2) Dyeing and finishing process: Fabric preparation - sewing - boiling shrinkage - dehydration - slitting - pre-preparation - fabric preparation - dyeing - reduction washing - acid washing - dehydration - opening and fabric preparation - finishing - rolling - quality inspection.

[0081] (2.1) Boiling and degreasing: The pretreatment for degreasing is carried out in a high temperature and high pressure dyeing tank. The formula is: degreasing agent DM-1147N 1g / L, soda ash 10g / L, bath ratio 1:18, temperature 80℃, time 45min, then drain the liquid and wash with water.

[0082] (2.2) Dyeing: Dyeing is carried out in a high temperature and high pressure overflow dyeing machine. In order to ensure the uniformity and stability of dyeing, the temperature change range of the cylinder is different at different temperature stages. When the temperature rises to 130℃, it is necessary to maintain a constant temperature for 50 minutes to ensure sufficient dyeing and fastness. Then, the temperature is gradually reduced to 80℃ for reduction washing to remove floating color. When the temperature drops to below 60℃, the liquid is drained and washed with water.

[0083] (2.3) Reduction cleaning: Clean in a high temperature and high pressure overflow dyeing machine. The formula is: sodium hydroxide 1g / L, sodium hydrosulfite 1g / L, reduction cleaning agent MCL (Clariant Chemicals [China] Co., Ltd.) 0.5g / L, heat bleaching at 80℃ for 20min.

[0084] The specific rhythm of heating and cooling during staining is as follows: Figure 8 As shown.

[0085] (2.4) Drying and setting: After the wet cloth is mechanically spun dry, it is dried and set by a setting machine. The drying speed is 60m / min, the drying temperature is 110℃, the overfeed is 3% during the drying process, and the drying tension is 18N. Hot air stretching and setting are used. The setting speed is 60m / min, the setting temperature is 120℃, the overfeed is 5% during the setting process, and the feeding tension is 18N.

[0086] The reverse side of the knitted fabric prepared in this embodiment has multiple protrusions and grooves.

[0087] Example 2: Effect Testing

[0088] 1. Contact area

[0089] Detection method: Place the knitted fabric of Example 1 on a glass plate, drip water evenly from the contact tip, and then take a picture to analyze the contact area of ​​the material.

[0090] Test results: Due to the special nature of textiles, the contact area is only about 70% of the wetted part.

[0091] Under simulated human sweating conditions, the contact area between the knitted fabric of Example 1 and the glass plate was less than 50% of the fabric area. The results show that, under conditions of intense human sweating, the sweat from the knitted fabric of Example 1 will not adhere to the skin surface due to surface tension, thus ensuring that the fabric will not stick to the body even when the body is sweating profusely.

[0092] 2. Moisture Detection

[0093] Test Method: Using a curved glass plate simulating the body and skin, the fabric was laid flat on the glass plate. 50 grams of water were evenly dripped from the top of the point where the fabric and glass plate contacted each other. The time it took for the water to reach the bottom of the fabric was measured and compared. After the water reached the bottom, the data from a balance placed under the fabric was compared to confirm the amount of water wicked away by the fabric. The speed and amount of water wicking away by the material were compared to evaluate the fabric's sweat wicking efficiency. Two materials with the same weight and composition were used in the test: one with a plain structure, using the most common conventional plain weave loop weave without grooves, and the other was a knitted fabric prepared in Example 1.

[0094] Test results: The comparison results of the water diversion distance are shown in Table 1 and... Figure 9 As shown in Table 2, the results of the comparison of water drainage quality are presented.

[0095] Table 1: Comparison of Distances for Water Diversion

[0096]

[0097] Table 2: Comparison of the quality of water diversion

[0098]

[0099] The test data clearly show that, in terms of distance, the knitted fabric of Example 1 has an average water-wicking speed that is more than 20% faster than that of the ordinary comparative material (Note: data with abnormal wetting at the beginning of the experiment are excluded). In terms of quality, the knitted fabric of Example 1 is 33.5% faster than the ordinary comparative material, and the final sweat-wicking mass is 22.2% greater.

[0100] 3. Tensile testing

[0101] Testing method: A fully soaked fabric is laid flat on a glass plate simulating skin. A tension gauge is then used to connect the fabric, and the fabric is pulled at a constant speed along the glass plate in a direction parallel to the horizontal plane. The data on the tension gauge is observed and read. This data represents the adhesion force of the fabric to the glass plate in a wet state, indicating the fabric's ability to adhere to the skin when fully soaked.

[0102] Test results: As shown in Table 3. The results indicate that the adhesion of the knitted fabric in Example 1 is significantly reduced. Compared with the control fabric, the adhesion is reduced by at least two times.

[0103] Table 3

[0104]

[0105] 4. Drying performance testing

[0106] Test method: The test method of GB / T862902017 is adopted. The drying time of the fabric is tested after spin-drying, which indicates the degree of spin-drying and the speed of drying.

[0107] Test results are shown in Table 4.

[0108] Table 4

[0109]

[0110] The test results were good, which indicates that after the knitted fabric in Example 1 is saturated with sweat, the raised grooves will dry quickly due to the non-hydrophilic fibers when wrung out, so there is no sticky feeling when in contact with the skin, and it can also form an easy-to-wring-dry function.

[0111] 5. Testing of the guiding and moisture-wicking function

[0112] Testing method: The knitted fabric prepared in Example 1 was sent to Zhonglian Inspection (Fujian) Testing Service Co., Ltd. for testing.

[0113] Test results: such as Figure 9As shown, the unidirectional moisture wicking index of the knitted fabric in Example 1 before washing is 2.98 times that of the standard index, and the unidirectional moisture wicking index after washing is 4.28 times that of the standard index. This indicates that the knitted fabric in Example 1 has excellent directional moisture wicking properties.

[0114] 5. Routine moisture absorption and quick-drying performance testing

[0115] The testing methods and results are shown in Table 5. As can be seen from the data in Table 5, the knitted fabric of Example 1 also achieved very good results in the conventional moisture absorption and quick-drying index tests. For example, a water droplet diffusion SEC of less than or equal to 6 after washing meets the requirements, while the SEC of the knitted fabric of this application is only 0.5. A core height of 80 mm before washing meets the requirements, while the warp and weft mm of the knitted fabric of this application are both greater than 185 mm, far exceeding the required values.

[0116] Table 5

[0117]

[0118] 6. Other performance tests

[0119] The knitted fabric prepared in Example 1 was sent to Zhonglian Inspection (Fujian) Testing Service Co., Ltd. for testing.

[0120] The test report shows that the knitted fabric prepared in Example 1 has a unidirectional conduction index 2.98 times that of the standard index before washing and a unidirectional conduction index 4.28 times that of the standard index after washing, which indicates that it has excellent directional and moisture-wicking properties.

[0121] Example 3

[0122] In this embodiment, the surface layer uses 32SJC (Siro compact spun) cotton yarn, which is treated with quick-drying process to improve the quick-drying performance of the cotton yarn. It accounts for 60% of the weight and the moisture regain of the cotton yarn is about 8%, which has excellent moisture absorption capacity.

[0123] The inner layer uses 75D / 72F cross-cut polyester DTY yarn. The standard moisture regain of polyester yarn is 0.4%, meaning it is not hydrophilic. However, the higher fiber count and the unique yarn structure create more capillary channels, resulting in excellent wicking ability. This allows it to effectively absorb and conduct sweat from the skin, accounting for 40% of the yarn's weight. The finished fabric weight is 170g / m². 2 The inner layer of the fabric features multiple parallel strip-shaped protrusions along the longitudinal direction. During weaving, the structural design of the fabric loop weave creates a distinct groove structure. The protrusions are 1mm wide, 1mm apart, and 0.2mm high.

[0124] The specific preparation process is as follows:

[0125] (1) Weaving: according to Figure 7 The needle arrangement shown is used for knitting on a 34-inch double-sided knitting machine, and the knitting method is as follows:

[0126] The fabric is divided into 12 loops: cotton yarn is the outer yarn, and polyester yarn is the inner yarn. Loops 2-4-6-...-12 are the inner yarn, and loops 1-3-5-...-11 are the outer yarn. Each loop consists of 8 stitches of the upper needle. Upper needle A loops with lower needles A / C in loops 1-3-7-9, creating yarn traction and forming dots on the outer yarn surface to facilitate the wicking of sweat to the front. In loops 5 and 11, upper needle A loops separately, forming a separate horizontal line for better sweat evaporation. The upper needles follow this pattern thereafter. Similarly, each loop of the lower needle consists of 8 stitches. First, lower needles loop separately in loops B, C, A, B in loops 2-4-8-10, and then loop A, B, C in loops 6-12, which better absorbs sweat. Every three lower needles are skipped, forming breathable vertical stripes to create the greige fabric.

[0127] (2) Dyeing and finishing process: Fabric preparation - sewing - scouring - washing - pre-ordering - fabric preparation - dyeing - soaping - color fixing - softening - dehydration - opening fabric preparation - drying - setting - rolling - quality inspection.

[0128] (2.1) Scouring: The pre-scouring treatment is carried out in a high-temperature and high-pressure dyeing vat to remove impurities from the fabric fibers. The concentration of scouring agent in the scouring liquor is 6-10 g / L, the concentration of H2O2 is 2-4 g / L, the concentration of NaOH is 1-3 g / L, and the liquor ratio is not less than 1:30. Scouring and finishing are carried out at 90-95℃ and kept at that temperature for 30-60 minutes. Then, the fabric is washed with water, first with hot water at 10-80℃, then with warm water, and finally with cold water, and then drained.

[0129] (2.2) Polyester dyeing: Dyeing is carried out in a high-temperature and high-pressure overflow dyeing machine. First, dye the polyester at high temperature, then dye the cotton at medium temperature. Add disperse dye, dispersing and leveling agent, pH adjuster (acetic acid / sodium acetate buffer system), and anti-wrinkle agent in the bath at room temperature. Increase the temperature to 80-90℃ at 1℃ / min (dye adsorption stage); increase the temperature to 125-130℃ at 1-1.5℃ / min (key dyeing and fixing temperature for polyester); keep at 125-130℃ for 30-60 minutes (to ensure that the dye fully diffuses into the fiber); cool down to 80-85℃ at a rate of 1-1.5℃ / min (must be slow to prevent the polyester from wrinkling and "chicken claw" marks due to sudden cooling and affecting dye fixation); drain the dye liquor; perform reduction washing to thoroughly remove the floating dye adsorbed on the cotton fibers and polyester surface, improve color fastness (especially rubbing fastness) and color brightness; gradually cool and wash with water until neutral.

[0130] (2.3) Cotton dyeing: For polyester dyed and washed fabric, add reactive dye, sodium sulfate (dyeing accelerator), and leveling agent at room temperature. Circulate evenly. Increase the temperature to **60℃** at 1-1.5℃ / min (commonly medium-temperature reactive dyes). Add alkali for color fixing: Add soda ash or a compound alkali agent (such as Soda Ash + NaOH) in portions or slowly, and keep at 60℃ for 30-60 minutes. Cool down to below 50℃ and drain the solution.

[0131] Add soap and detergent, heat to 80-95℃, keep warm for 10-20 minutes to thoroughly remove unfixed dyes and hydrolyzed dyes. Gradually cool and rinse with water until neutral.

[0132] (2.4) Post-treatment: Use cotton fixing agent to further improve wet fastness (especially wet rubbing fastness); softening finishing (hydrophilic softening oil silicone PE), use a centrifugal dewatering machine or padding machine to remove most of the moisture, and cut the cylindrical fabric into flat widths. Use a rotary dryer or tenter tumble dryer to dry under low tension, and the temperature is generally controlled at 100-120℃.

[0133] (2.5) The process is carried out on a needle plate type hot air tenter frame, with the temperature controlled at 190-195°C. The setting time is 30 seconds. After exiting the drying room, the product is immediately cooled to room temperature with cold air to fix its shape.

[0134] The reverse side of the knitted fabric prepared in this embodiment has multiple protrusions and grooves.

[0135] Example 4: Effect Detection

[0136] The Fujian Provincial Fiber Inspection Center was commissioned to conduct adhesion performance testing on the knitted fabric prepared in Example 3. The test results show that the maximum adhesion force of the knitted fabric prepared in Example 3 is 30.3 cN. This indicates that the fabric is highly comfortable and does not easily stick to the skin due to sweating.

[0137] The knitted fabric prepared in Example 3 was sent to Zhonglian Inspection (Fujian) Testing Service Co., Ltd. for testing of its moisture-wicking, quick-drying, and unidirectional moisture-wicking properties. The test results for moisture-wicking, quick-drying, and unidirectional moisture-wicking properties show that the knitted fabric prepared in Example 3 achieved a perfect score of "Level 5" in all aspects of water absorption, moisture wicking, and diffusion. Its quick-drying performance is stable, and it is durable and washable, fully meeting the stringent requirements for "moisture-wicking and quick-drying" in high-end sports, yoga, running, and outdoor activities.

[0138] In summary, the fabric of this invention employs a double-layer structure, combined with yarns of different structures and F numbers, forming a grooved structure. This results in a fabric with better one-way moisture wicking and sweat-wicking capabilities. The grooved structure of the fabric not only reduces the effective contact area between the fabric and the skin, creating a microcirculation of moisture on the skin, but the longitudinal grooves also better collect and wick away sweat, preventing it from forming a water film. This ensures that the fabric doesn't stick to the skin even during heavy sweating, thus significantly improving the material's overall sweat management capabilities and enhancing the dry and comfortable wearing experience.

[0139] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0140] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the appended claims.
