Description

Technical Field

[0001] This invention relates to a textile fabric, and more particularly to a non-sticky warp-knitted elastic fabric. Background Technology

[0002] Highly elastic fabrics have good resilience and are often used as outdoor sports fabrics: good stretchability continuously promotes the convenience of outdoor activities, quickly and effectively protects muscles from the energy loss during stretching, and the elasticity of the fabric allows the clothing to keep pace with the rhythm of movement.

[0003] In the current technology, the structure of elastic fabrics is simple, the rebound ability is not obvious, and the function is limited. When wearing them in hot weather or during exercise, the sweat produced by the human body is not easily evaporated, which affects health and cannot meet the needs of use.

[0004] For example, Chinese patent document CN209904152 discloses "a breathable high-elastic knitted fabric, comprising a knitted fabric body and a second elastic layer. A knitted layer is disposed in the middle of the interior of the knitted fabric body, and a first elastic layer is adhered to the upper side of the knitted layer. A first breathable layer is disposed above the first elastic layer, and a polyester fiber layer is adhered to the upper side of the first breathable layer. The second elastic layer is adhered to the lower side of the knitted layer, and a second breathable layer is disposed below the second elastic layer. A sweat-absorbing layer is adhered to the lower side of the second breathable layer, and a breathable mesh layer is woven inside the second breathable layer." While the first and second elastic layers in this fabric enhance the elasticity of the knitted fabric body, their tightness prevents breathability, making it difficult for sweat to evaporate. To improve breathability, a multi-layered structure is created, consisting of a breathable layer, a polyester fiber layer, and a sweat-absorbing layer, forming a bonded fabric. This process is cumbersome and also results in the fabric sticking to the body after sweating.

[0005] For example, Chinese patent document CN215970544 discloses "an elastic fabric with good resilience. The elastic fabric with good resilience includes a base layer, a breathable layer on top of the base layer, an elastic layer on top of the breathable layer, an antibacterial layer on top of the elastic layer, a protective layer on top of the antibacterial layer, and a plurality of transverse elastic strips and a plurality of longitudinal elastic strips inside the elastic layer." Similarly, this fabric has a breathable layer, an antibacterial layer, and a protective layer on top of the elastic layer, forming a SPACER structure. Although the elastic layer improves the elasticity of the fabric, the multi-layer structure reduces the breathability of the fabric. At the same time, sweat is absorbed through the antibacterial layer, which can play a good antibacterial and bacteriostatic role and prevent bacterial growth, but the moisture in the sweat still remains in the fabric, making the fabric stick to the body and causing discomfort when wearing it, thus failing to meet the needs of use.

[0006] Therefore, there is an urgent need for a warp-knitted elastic fabric that is breathable, quick-drying, and does not easily curl and stick to the body. Summary of the Invention

[0007] The purpose of this invention is to provide a non-sticky warp-knitted elastic fabric that not only does not stick to the body, but also has the functions of good breathability, quick-drying and moisture absorption and is not easy to curl.

[0008] To achieve the above objectives, the present invention provides a non-sticky warp-knitted elastic fabric, comprising a fabric body with a warp-knitted structure. The fabric body includes at least a low-loft yarn Y1, a high-loft yarn Y2, and an elastic yarn Y3. The low-loft yarn Y1, high-loft yarn Y2, and elastic yarn Y3 are woven together using a comb-and-grow method to form the fabric body. The low-loft yarn Y1 and the high-loft yarn Y2 are both located on the surface of the fabric body and are arranged alternately. The low-loft yarn Y1 forms a low-loft structure in the fabric body through the comb-and-grow method. The low-loft structure is formed by the low-loft yarn Y1 being woven into the fabric body. i empty b i The basic unit is formed and cycled until full width is reached. The expression for the passage and emptiness of one of the basic units is a. i b i , 1≤a i ≤50, 1≤b i ≤50; where a i b represents the yarn guide needle used for threading yarn. i The guide needle indicates a looped yarn; a loop unit consists of at least one basic unit and at most 10 different basic units to form a loop unit, repeated along the width direction until full width; the high-loft yarn Y2 forms a high-loft structure in the combing and threading method in the fabric body, and the high-loft structure is formed by the high-loft yarn Y2 with a looped yarn. j Wear n j The basic unit is formed and cycled until full width is reached. The expression for the penetration and emptiness of one of the basic units is m. j n j , 1≤m j ≤50, 1≤n j ≤50; where m j n represents the guide needle for unthreaded yarn passing. j The yarn guide needle indicates the yarn feeding process; a loop unit consists of at least one basic unit and at most 10 different basic units to form a loop unit, which is repeated along the width direction until the full width is reached; the elastic yarn Y3 forms an elastic structure in the combing and threading method in the fabric body, and the elastic structure is formed by the elastic yarn Y3 in the combing and full threading method; the low bulk yarn Y1 and the high bulk yarn Y2 both form a raised structure on the skin-contact surface of the fabric body.

[0009] Compared with the prior art, the non-sticky warp-knitted elastic fabric of the present invention includes a fabric body with a warp-knitted structure. The fabric body includes at least three types of yarns: low-loft yarn Y1, high-loft yarn Y2, and elastic yarn Y3. The low-loft yarn Y1 and high-loft yarn Y2 are both located on the surface of the fabric body and are arranged alternately. Based on the well-known prior art that a smooth surface with higher moisture content will be smoother and have stronger skin-sticking force, the present invention utilizes the characteristic that high-loft yarn Y2 absorbs water faster than low-loft yarn Y1, and combines this with the structure of their alternating arrangement to effectively reduce the moisture content of low-loft yarn Y1, thereby reducing the skin-sticking force of low-loft yarn Y1 after wetting. This makes the present invention non-sticky. Simultaneously, the bulkiness and crimp of high-loft yarn Y2 make its contact with the skin point-like, resulting in a smaller contact area, further improving the non-sticky performance and breathability of the present invention. Meanwhile, this invention also enables the fabric body to absorb water from the skin through the high-loft yarn Y2, and transfer the moisture to the low-loft yarn Y1 through capillary effect, thus accelerating quick drying. The alternating arrangement of the low-loft yarn Y1 and the high-loft yarn Y2 in this invention greatly improves the moisture absorption and quick drying ability while significantly reducing the stickiness to the skin, giving this invention excellent non-sticky properties. At the same time, the combination of the three yarns—low-loft yarn Y1, high-loft yarn Y2, and elastic yarn Y3—ensures the elasticity of the fabric body while forming microscopic uneven spaces and more pores between the yarns, resulting in better air circulation and increased breathability of the fabric. Therefore, the non-sticky warp-knitted elastic fabric of this invention not only does not stick to the body, but also has the functions of good breathability, quick-drying and moisture absorption, and is not easy to curl at the edges. This makes the non-sticky warp-knitted elastic fabric of this invention have the characteristics of large opening, good resilience, and arbitrary cutting. It is dry and comfortable to wear, keeping the skin dry and comfortable at all times. It is highly practical and effective. It is very suitable for making clothing that comes into contact with the skin, such as underwear, T-shirts, trousers and shirts, which can meet people's needs for wearing comfort, functionality and practicality. It has a wide range of applications and good market prospects and economic and social benefits.

[0010] Preferably, the raised structure of the non-sticky warp-knitted elastic fabric of the present invention is dot-shaped or linear. The dot-shaped or linear raised structure effectively reduces stickiness to the skin, improves airflow, and increases the fabric's breathability, making it more comfortable and suitable to wear.

[0013] Preferably, in the non-sticky warp-knitted elastic fabric of the present invention, the low-loft yarn Y1 is FDY yarn, the high-loft yarn Y2 is DTY yarn, and the elastic yarn Y3 is ATY yarn, with the loft of the FDY yarn, DTY yarn, and ATY yarn increasing sequentially from low to high.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to specific examples and accompanying drawings, and the technical solutions of the present invention will be explained. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Embodiments of the present invention will now be described with reference to the accompanying drawings, in which similar element reference numerals represent similar elements.

[0028] The warp-knitted elastic fabric of the present invention includes a fabric body with a warp-knitted structure. The fabric body includes at least a low-loft yarn Y1, a high-loft yarn Y2, and an elastic yarn Y3. The low-loft yarn Y1, high-loft yarn Y2, and elastic yarn Y3 are woven together using a comb-and-grow method to form the fabric body. The low-loft yarn Y1 and high-loft yarn Y2 are both located on the surface layer of the fabric body and are arranged alternately. The low-loft yarn Y1 forms a low-loft structure in the fabric body through the comb-and-grow method. The low-loft structure is formed by the low-loft yarn Y1 being woven into the fabric body. i empty b i The basic unit is formed and cycled until full width is reached. The expression for the passage and emptiness of one of the basic units is a. i b j , 1≤a i ≤50, 1≤b i ≤50; where a i b represents the yarn guide needle used for threading yarn. iThe guide needle indicates a looped yarn; a loop unit consists of at least one basic unit and at most 10 different basic units to form a loop unit, repeated along the width direction until full width; the high-loft yarn Y2 forms a high-loft structure in the combing and threading method in the fabric body, and the high-loft structure is formed by the high-loft yarn Y2 with a looped yarn. j Wear n j The basic unit is formed and cycled until full width is reached. The expression for the penetration and emptiness of one of the basic units is m. j n j , 1≤m j ≤50, 1≤n j ≤50; where m j n represents the guide needle for unthreaded yarn passing. j The yarn guide needle indicates the yarn feeding process; a loop unit consists of at least one basic unit and at most 10 different basic units to form a loop unit, which is repeated along the width direction until the full width is reached; the elastic yarn Y3 forms an elastic structure in the combing and threading method in the fabric body, and the elastic structure is formed by the elastic yarn Y3 in the combing and full threading method; the low bulk yarn Y1 and the high bulk yarn Y2 both form a raised structure on the skin-contact surface of the fabric body. The non-sticky warp-knitted elastic fabric of the present invention comprises a fabric body with a warp-knitted structure, which includes at least three types of yarns: low-bulk yarn Y1, high-bulk yarn Y2, and elastic yarn Y3. The low-bulk yarn Y1 and high-bulk yarn Y2 are both located on the surface of the fabric body and are arranged alternately. Based on the well-known prior art that a smooth surface with higher moisture content will be smoother and have stronger skin-sticking force, the present invention utilizes the characteristic that high-bulk yarn Y2 absorbs water faster than low-bulk yarn Y1, combined with their alternately arranged structure, to effectively reduce the moisture content of low-bulk yarn Y1, thereby reducing the skin-sticking force of low-bulk yarn Y1 after wetting, thus making the fabric non-sticky. Simultaneously, the bulk and crimp of high-bulk yarn Y2 ensures point-like contact with the skin, resulting in a smaller contact area and further improving the non-sticky performance and breathability of the present invention. Meanwhile, this invention also enables the fabric body to absorb water from the skin through the high-loft yarn Y2, and transfer the moisture to the low-loft yarn Y1 through capillary effect, thus accelerating quick drying. The alternating arrangement of the low-loft yarn Y1 and the high-loft yarn Y2 in this invention greatly improves the moisture absorption and quick drying ability while significantly reducing the stickiness to the skin, giving this invention excellent non-sticky properties. At the same time, the combination of the three yarns of this invention—low-loft yarn Y1, high-loft yarn Y2, and elastic yarn Y3—while ensuring the elasticity of the fabric body, also creates microscopic high and low uneven spaces and more pores between the yarns through the formed convex structure, which improves air circulation and increases the breathability of the fabric.

[0029] In summary, the non-sticky warp-knitted elastic fabric of this invention not only avoids clinging to the skin but also possesses excellent breathability, quick-drying properties, and resistance to curling. This results in a fabric with a large opening, good resilience, and the ability to be cut to any size. It provides a dry and comfortable feel without sticking to the skin, keeping the skin dry and comfortable at all times. It is highly practical and effective, making it ideal for manufacturing clothing that comes into contact with the skin, such as underwear, T-shirts, trousers, and shirts. It meets people's needs for comfort, functionality, and practicality, has a wide range of applications, and possesses excellent market prospects and economic and social benefits.

[0030] To further improve the non-stickiness and breathability of the present invention, preferably, the raised structure of the non-sticky warp-knitted elastic fabric of the present invention is dotted or linear. The dotted or linear raised structure effectively reduces stickiness to the skin, improves air circulation, and increases the breathability of the fabric, making it more comfortable and suitable to wear.

[0031] This invention further improves the non-sticky, breathable, quick-drying, and non-curling properties of the present invention. Preferably, the ratio of the number of low-bulk yarns Y1 to high-bulk yarns Y2 in the non-sticky warp-knitted elastic fabric of the present invention is between 1:3 and 3:1, and the ratio of the linear density of the low-bulk yarns Y1 to the high-bulk yarns Y2 is between 0.5 and 3.5. More specifically, the ratio of the linear density of the low-bulk yarns Y1 to the high-bulk yarns Y2 in the non-sticky warp-knitted elastic fabric of the present invention is between 0.9 and 1.2, and the linear density of either the low-bulk yarns Y1 or the high-bulk yarns Y2 is 7-100 denier.

[0032] Preferably, in the non-sticky warp-knitted elastic fabric of the present invention, the low-loft yarn Y1 is FDY yarn, the high-loft yarn Y2 is DTY yarn, and the elastic yarn Y3 is ATY yarn, with the loft of the FDY, DTY, and ATY yarns increasing sequentially. Because the present invention is a warp-knitted fabric structure, and uses alternating high-loft yarns (DTY yarn) and low-loft yarns (FDY yarn) in the yarn arrangement, the higher the moisture content of the smooth surface, the smoother it is, and the stronger its stickiness to the skin. DTY yarn absorbs water faster than FDY yarn, reducing the moisture content of the FDY yarn and thus reducing its stickiness after wetting. The loft and crimp of DTY yarn make its contact with the skin point-like, with a small contact area. DTY yarn absorbs water from the skin and conducts it to the FDY yarn through capillary effect, spreading and accelerating drying. Therefore, the structure of FDY yarn interspersed with DTY yarn is beneficial for moisture absorption, quick drying, and reducing stickiness. Furthermore, the FDY and DTY yarns form a very obvious microscopic uneven space and more inter-yarn pores, further improving air circulation and increasing the fabric's breathability. More specifically, the low-loft structure of the non-sticky warp-knitted elastic fabric of the present invention uses the same comb-pin alignment method as the high-loft structure, wherein a... i =m j And b i =n j Among them: FDY is the abbreviation for Fully drawn yarn, which translates to "fully drawn yarn" in Chinese; DTY is the abbreviation for Draw texturing yarn, which translates to "stretched textured yarn" in Chinese; ATY is the abbreviation for Air Textured Yarn, which translates to "air-textured yarn" in Chinese.

[0033] Preferably, in the non-sticky warp-knitted elastic fabric of the present invention, the padding numbers of the low-bulk yarn Y1 and the high-bulk yarn Y2 are both 1-0 / 2-3 / / or 0-1 / 2-1 / / or 1-0 / 1-2 / 2-3 / 2-1 / / , and the padding number of the elastic yarn Y3 is 0-2 / 3-1 / / or 1-0 / 1-2 / / or 1-0 / 1-2 / 2-3 / 2-1 / / .

[0034] Preferably, in the non-sticky warp-knitted elastic fabric of the present invention, the low-loft yarn Y1, high-loft yarn Y2, and elastic yarn Y3 are arranged in loops of each comb yarn in the fabric body in one of the following structures or any combination: fully open structure, fully closed structure, one open and one closed structure.

[0035] Preferably, the fabric body of the non-sticky warp-knitted elastic fabric of the present invention has a single-sided jacquard or double-sided jacquard structure.

[0036] Preferably, the bottom surface of the non-sticky warp-knitted elastic fabric of the present invention has a napped structure. This napped structure creates a raised nap effect, thereby improving the feel of the fabric. Further, this napped structure can be obtained through a napping process.

[0037] Preferably, the low-loft yarn Y1 of the non-sticky warp-knitted elastic fabric of the present invention is a chemical fiber yarn; the high-loft yarn Y2 of the present invention is a staple fiber yarn.

[0038] To further illustrate the invention and its embodiments, the low-loft yarn Y1, high-loft yarn Y2, and elastic yarn Y3 will be represented by symbols known to those skilled in the art: low-loft yarn Y1 will be represented by yarn Y1, high-loft yarn Y2 by yarn Y2, and elastic yarn Y3 by yarn Y3. Additionally, in the following text, PA6 refers to Nylon 6; FD is short for full dull; and PU is short for polyurethane.

[0039] Combination Figure 1 - Figure 7 Tables 1 and 2 provide further detailed descriptions of the invention's non-sticky warp-knitted elastic fabric:

[0040] Example 1: Using a 40-needle warp knitting machine, a i =m j =1 and b i =n j =1. Yarn Y1 uses PA6 25 / 34FD FDY yarn, with a 1-through-1-open threading method; yarn Y2 uses PA6 25 / 34FD DTY yarn, with a 1-open-1-through threading method; 1-interval-1-through threading, with a structure of 1-0 / 2-3 / / (i.e., the yarn padding numbers for yarns Y1 and Y2), and a yarn feed of 1220mm / razel; yarn Y3 uses PU 20D, with a 100% draft ratio at the yarn head, a structure of 0-2 / 3-1 / / , full threading, and a yarn feed of 1300mm / razel. The yarn is then knitted through a series of downstream processes including washing, pre-dyeing, dyeing, and finishing. The resulting finished product has the following specifications: 170cm * 130g / m². 2 .

[0041] Comparative Example 1: A 40-needle warp knitting machine was used with PA6 25 / 34FD FDY yarn, full thread, 1-0 / 2-3 / / weave, and a yarn feed of 1220 mm / rubc. The elastic yarn used was PU 20D, with a 100% head draft ratio, 0-2 / 3-1 / / weave, full thread, and a yarn feed of 1300 mm / rubc. The knitting process included washing, pre-setting, dyeing, and finishing. The resulting finished product measured 160cm x 150g / m². 2.

[0042] Comparative Example 2: A 40-needle warp knitting machine was used with PA6 25 / 34FD DTY yarn, full thread, 1-0 / 2-3 / / weave, and a yarn feed of 1220 mm / rubc. The elastic yarn used was PU 20D, with a 100% head draft ratio, 0-2 / 3-1 / / weave, full thread, and a yarn feed of 1300 mm / rubc. The knitting process included washing, pre-dyeing, dyeing, and finishing. The resulting finished product measured 160cm x 145g / m². 2 .

[0043] All the above fabrics were treated with the same moisture-wicking and quick-drying finishing process. The fabrics were then tested for moisture-wicking and quick-drying properties, one-way moisture wicking, breathability, and skin adhesion.

[0044] Sampling: In this experiment, 0.5 yards of fabric were taken from the front, middle and back sections of a 50-yard roll. Three samples were taken: one sample was used for moisture absorption and quick-drying test, one sample was used for unidirectional moisture wicking test, one sample was used for breathability test, and one sample was used for skin adhesion test.

[0045] Moisture absorption and quick-drying test: Using the JIS L1907 method, moisture absorption and quick-drying tests were conducted on three pieces of fabric from one sample. The average value of the moisture absorption and quick-drying values ​​of the three pieces of fabric was taken as the moisture absorption and quick-drying value of the fabric.

[0046] Breathability test: Using JIS L 1096 Method A, the breathability of three pieces of fabric from one sample was tested on the left, center and right sides of each piece of fabric, and the average value was taken as the breathability value of each piece; the breathability values ​​of the three pieces of fabric were then averaged to obtain the final breathability value of the fabric.

[0047] One-way moisture wicking test: AATCC 195 "Liquid Moisture Management Properties of Textile Fabrics" was used for measurement. One-way moisture wicking capability (OWTC) was tested on three fabric pieces from one sample, and the average OWTC value of the three fabric pieces was taken as the OWTC value of the fabric.

[0048]

[0049] As analyzed in Table 1, all the fabrics treated with the same moisture-wicking and quick-drying finishing process exhibit good moisture absorption. DTY's quick-drying properties are slightly worse than FDY's. Example 1 and Comparative Example 2 demonstrate good moisture absorption and quick-drying properties. Comparative Example 2 shows the best unidirectional moisture transfer performance, indicating that DTY yarn has better unidirectional moisture transfer performance than FDY yarn. In terms of breathability, Example 1 performs better. Overall, Example 1 demonstrates excellent performance in both moisture absorption / quick-drying and breathability.

[0050] The skin adhesion test is as follows:

[0051] Experimental equipment: Zwick tensile testing machine, 5N sensor, self-made coefficient of friction meter, friction block (2×2cm smooth copper block without sharp edges, contact surface uncovered)

[0052] Test sample: Warp (L) & Weft (W): 8×12cm. Fold each end of the 12cm direction inward by 1cm and then sew it together so that the effective distance in the middle is 8cm, i.e., 8×8cm.

[0053] Test conditions:

[0054] Water drop volume: 0.2 mL (drop water to the center of the sample to allow it to diffuse, with a total penetration time of 30 seconds, then start timing at 0 min, and test every 5 minutes.)

[0055] Expected tension: 0.1N

[0056] Pre-tensioning speed: 50 mm / min

[0057] Stretching speed: 200mm / min

[0058] Tensile displacement: 60mm

[0059] Operating method: Straighten the sewing thread (ensuring minimal tension) and fix it on the friction coefficient meter. Test directly in the dry state, or test after dripping water (timing) in the wet state. The friction block slides from the edge of an 8×8cm fabric piece, and the values ​​are recorded at the 30mm, 40mm, and 50mm positions.

[0060] This experiment simulates the watery environment between the skin and clothing after sweating. The frictional force measured in a wet state is used to characterize the adhesive force between the skin and fabric after sweating. The adhesive force f is defined as: f = f L +f w f L For radial friction, f w The friction force is in the latitudinal direction. This experiment mainly focuses on the friction force on the back side of the skin. Under dry conditions, the data of the adhesion force were recorded after 0 min, 5 min, 10 min, 15 min, 20 min, 25 min, and 30 min of water dripping, as shown in Table 2.

[0061]

[0062]

[0063] To facilitate observation and analysis, a trend chart was created using the dripping data at the 50mm mark in Table 2 over 30 minutes. (See attached chart.) Figure 1 .

[0064] Depend on Figure 1 It can be seen that after water is dripped, the adhesive force suddenly increases. As the water slowly penetrates from the skin and spreads to the other side, the adhesive force gradually decreases. When completely dry, it returns to the initial minimum adhesive force. In Example 1 and Comparative Example 1, the adhesive force is lower than that of Comparative Example 1 within 30 minutes after water is dripped. Therefore, Example 1 has less adhesive force in the wet state and has a better non-sticky effect.

[0065] In summary, when the fabric was tested for moisture absorption and quick-drying properties, breathability, one-way moisture wicking performance, and skin stickiness, Example 1 showed excellent performance in all aspects, demonstrating good moisture absorption and quick-drying, breathability, and non-stickiness.

[0067] Example 3: As Figure 4 As shown, yarn Y1 is FDY yarn with a 1-through-1-empty threading method; yarn Y2 is DTY yarn with a 1-empty-1-through threading method; yarns Y1 and Y2 have the same guide bar and needle alignment; the padding numbers for yarns Y1 and Y2 are 0-1 / 2-1 / / ; yarn Y3 is spandex with full threading and padding numbers are 1-0 / 1-2 / / .

[0068] Example 4: Figure 5 As shown, yarn Y1 is FDY yarn with a 1-through-1-empty threading method; yarn Y2 is DTY yarn with a 1-empty-1-through threading method; yarns Y1 and Y2 have the same guide bar and needle alignment; the padding numbers for yarns Y1 and Y2 are 1-0 / 1-2 / 2-3 / 2-1 / / ; yarn Y3 is spandex with full threading and padding numbers are 1-0 / 1-2 / 2-3 / 2-1 / / .

[0069] Example 5: Figure 6 As shown, a i =m j =1 and b i =n j =2, Yarn Y1 is FDY yarn, threading method 1 thread 2 loop, yarn Y2 is DTY yarn, threading method 1 loop 2 thread, yarn Y1 and yarn Y2 have the same guide bar and needle alignment, yarn Y1 and yarn Y2 padding numbers are 1-0 / 2-3 / / , yarn Y3 is spandex, full threading, padding number is 0-2 / 3-1 / / .

[0070] Example 6: As Figure 7 As shown, a i =m j =2 and b i =n j =3, Yarn Y1 is FDY yarn, threading method 2 threading 3 open, Yarn Y2 is DTY yarn, threading method 2 open 3 threading, Yarn Y1 and Yarn Y2 have the same guide bar and needle alignment, Yarn Y1 and Yarn Y2 padding numbers are 1-0 / 2-3 / / , Yarn Y3 is spandex, full threading, padding numbers are 0-2 / 3-1 / / .

[0071] Example 7: Based on Example 3, yarn Y1 is replaced with synthetic fiber, with a 1-through-1-open threading method; yarn Y2 is replaced with staple fiber, with a 1-open-1-through threading method; the guide bars for yarns Y1 and Y2 are the same; the padding numbers for yarns Y1 and Y2 are 0-1 / 2-1 / / ; yarn Y3 is spandex, fully threaded, with padding numbers 1-0 / 1-2 / / (the structure is the same as in Example 3). By utilizing the characteristics of staple fiber yarns—more fibers and more pores between fibers—and the faster water absorption of Y2 staple fiber yarn compared to Y1 synthetic fiber, combined with their alternating arrangement, the water content of synthetic fiber Y1 is effectively reduced, thereby reducing its stickiness to the skin after wetting. Simultaneously, staple fiber Y2 absorbs water from the skin and transfers it to synthetic fiber Y1 through capillary action, thus accelerating drying. Furthermore, when short fiber Y2 and chemical fiber Y1 are arranged side by side or interwoven, the cohesion is not as tight as that between chemical fibers, resulting in more gaps between the yarns in the fabric, which improves air circulation and increases the breathability of the fabric.

[0072] Example 8: Based on Example 6, yarn Y1 is replaced with chemical fiber, with a 2-through-3-open threading method; yarn Y2 is replaced with short fiber, with a 2-open-3-through threading method; the guide bars of yarns Y1 and Y2 are the same; the padding numbers for yarns Y1 and Y2 are 1-0 / 2-3 / / ; yarn Y3 is spandex, with full threading and padding numbers 0-2 / 3-1 / / . (The structure is the same as in Example 6).

[0073] The yarn Y3 of this invention is preferably spandex or polyolefin.
