Description

Technical Field

[0001] This application relates to textile fabrics, and particularly to warp knitted elastic fabrics that do not adhere to the body.

Background Art

[0002] High-elastic fabrics have good resilience and are usually used as fabrics for outdoor sports. Fabrics with good elasticity always promote the ease of outdoor activities, quickly and effectively protect the muscle from the force consumption when stretching, and always synchronize the tempo of wearing and movement with the elasticity of the fabric.

[0003] In the prior art, current elastic fabrics have a simple structure, insufficient resilience, and only one function. When worn on a hot day or during exercise, the sweat emitted from the human body is difficult to volatilize, which affects the health of the body and cannot meet the usage needs.

[0004] For example, in Chinese Patent No. 209904152, it is disclosed that "a breathable high-elastic knitted fabric including a knitted fabric body and a second elastic layer, wherein a knitted layer is installed in the middle inside the knitted fabric body, and a first elastic layer is adhered above the knitted layer. A first ventilation layer is installed above the first elastic layer, and a polyester fiber layer is adhered above the first ventilation layer. The second elastic layer is adhered below the knitted layer, and a second ventilation layer is installed below the second elastic layer. A sweat-absorbing layer is adhered below the second ventilation layer, and a ventilation mesh layer is woven inside the second ventilation layer". Although the first elastic layer and the second elastic layer installed in this fabric strengthen the elasticity of the knitted fabric body, they are quite dense and have poor air permeability, so the sweat generated from the human body is difficult to volatilize. In order to improve air permeability, a multi-layer structure of a ventilation layer, a polyester fiber layer, and a sweat-absorbing layer is adhered to form a laminated fabric, but the process is complicated, and there is also a problem that the fabric adheres to the body after sweating.

[0005] For example, in Chinese Patent No. 215970544, it is disclosed that "an elastic fabric with good resilience. The elastic fabric with good resilience includes a base layer, a ventilation layer is installed on the top of the base layer, an elastic layer is installed on the top of the ventilation layer, a sterilization layer is installed on the top of the elastic layer, and a protective layer is installed on the top of the sterilization layer. Inside the elastic layer, several horizontal elastic strips and several vertical elastic strips are installed". Similarly, in this fabric, a ventilation layer, a sterilization layer and a protective layer are installed based on the elastic layer, forming a SPACER structure. However, although the elasticity of the fabric is enhanced by installing the elastic layer, the air permeability of the fabric is weakened due to the multi-layer structure. Also, since sweat is absorbed by the sterilization layer, the antibacterial and bacteriostatic effect is high and the reproduction of bacteria can be prevented. However, the moisture in the sweat still remains in the fabric, making the fabric easily stick to the body, resulting in poor comfort and unable to meet the usage needs.

[0006] Therefore, there is an urgent need for a warp-knitted elastic fabric that has good air permeability, absorbs and dries moisture quickly, has edges that are not easily rounded, and does not stick to the body.

Summary of the Invention

[0007] The object of the present application is to provide a warp-knitted elastic fabric that does not stick to the body, and the warp-knitted elastic fabric that does not stick to the body not only does not stick to the body, but also has functions such as good air permeability, quick moisture absorption and drying, and edges that are not easily rounded.

[0008] To achieve the above object, the present application provides a warp-knitted elastic fabric that does not stick to the body, including a fabric body presenting a warp-knitted structure. The fabric body includes at least a low-bulk yarn Y1, a high-bulk yarn Y2 and an elastic yarn Y3. The low-bulk yarn Y1, the high-bulk yarn Y2 and the elastic yarn Y3 are woven in a harness-through manner to form the fabric body. Both the low-bulk yarn Y1 and the high-bulk yarn Y2 are located on the surface layer of the fabric body, and the two are arranged at intervals. The low-bulk yarn Y1 forms a low-bulk structure in the fabric body in a harness-through manner. The low-bulk structure is a formed by passing through a by the low-bulk yarn Y1 iDo not pass b i forms a basic unit of this kind and circulates it throughout the width. Whether a thread passes through or not in one of the basic units is a i , b i is represented by, where 1 ≤ a i ≤ 50, 1 ≤ b i ≤ 50. Among them, a i is a guide needle through which the thread passes, and b i is a guide needle through which the thread does not pass. The circulation unit is formed by combining at least one and at most no more than 10 different basic units into one circulation unit, and is repeated along the width direction over the entire width. The low-bulky yarn Y2 forms a high-bulky structure in the fabric body in the reed-through method. The high-bulky structure is formed by the basic unit of not passing through m j and passing through n j of the high-bulky yarn Y2. It forms a basic unit of this kind and circulates it throughout the width. Whether a thread passes through or not in one of the basic units is m j , n j is represented by, where 1 ≤ m j ≤ 50, 1 ≤ n j ≤ 50. Among them, m j is a guide needle through which the thread does not pass, and n j is a guide needle through which the thread passes. The circulation unit is formed by combining at least one and at most no more than 10 different basic units into one circulation unit, and is repeated along the width direction over the entire width. The elastic yarn Y3 forms an elastic structure in the fabric body in the reed-through method. The elastic structure is formed by passing the elastic yarn Y3 through all the reeds. Both the low-bulky yarn Y1 and the high-bulky yarn Y2 form a convex structure on the surface of the fabric body that touches the skin.

[0009] Compared with the prior art, the warp-knitted elastic fabric that does not adhere to the body of the present application includes a fabric body presenting a warp-knitted structure. The fabric body includes at least three types of yarns, namely, low-bulk yarn Y1, high-bulk yarn Y2, and elastic yarn Y3. Both the low-bulk yarn Y1 and the high-bulk yarn Y2 are located on the surface layer of the fabric body and are arranged at intervals. By combining with the well-known prior art that the smooth surface becomes flatter as the moisture content increases and the force of adhering to the skin becomes stronger, in the present application, the feature that the high-bulk yarn Y2 has higher water absorption than the low-bulk yarn Y1 is utilized, and combined with the structure of arranging the two at intervals, the moisture content of the low-bulk yarn Y1 is effectively reduced. Thereby, the low-bulk yarn Y1 gets wet and weakens the force of adhering to the skin, so that the present application does not adhere to the body. At the same time, by utilizing the bulkiness and curling property of the high-bulk yarn Y2 to make the contact with the skin a point contact, the contact area is reduced, and it can be seen that the performance of not adhering to the body and the air permeability of the present application are further enhanced. Also, in the present application, the fabric body of the present application absorbs water from the skin by the high-bulk yarn Y2, and the moisture is transmitted to the low-bulk yarn Y1 by capillary action, thereby transmitting and diffusing the moisture and accelerating the quick drying. The structure of arranging the low-bulk yarn Y1 and the high-bulk yarn Y2 of the present application at intervals greatly enhances the ability of moisture absorption and quick drying, and at the same time greatly reduces the effect of the force of adhering to the skin, giving the present application excellent performance of not adhering to the body. At the same time, by combining the three types of yarns, namely, the low-bulk yarn Y1, the high-bulk yarn Y2, and the elastic yarn Y3 of the present application, while ensuring that the fabric body has elasticity, more micro high-low uneven spaces and more gaps between yarns are formed, further improving the air circulation and enhancing the air permeability of the fabric.Therefore, the warp-knitted elastic fabric that does not adhere to the body of the present application not only does not adhere to the body, but also has functions such as good air permeability, quick moisture absorption and drying, and the edges are not easy to curl. The warp-knitted elastic fabric that does not adhere to the body of the present application is provided with characteristics such as a large opening degree, good recoverability, and can be arbitrarily cut. When worn, it is refreshingly comfortable and does not adhere to the body, and always keeps the surface of the human skin smooth and comfortable. Therefore, it has high practicality and obvious effects, and is very suitable for making clothes that come into contact with the skin, such as underwear, T-shirts, trousers, and shirts. It can meet people's needs for comfort, functionality, and practicality, has a wide application range, and has good market prospects, economic, and social effects and benefits.

[0010] Preferably, the convex structure of the warp-knitted elastic fabric that does not adhere to the body of the present application presents a dot shape or a linear shape. The dot-shaped or linear convex structure not only effectively reduces the adhesiveness in contact with the skin, but also further enhances the air circulation and increases the air permeability of the fabric, making the wearing comfort moderately comfortable.

[0013] Preferably, the low-bulky yarn Y1 of the warp-knitted elastic fabric that does not adhere to the body of the present application is FDY yarn, the high-bulky yarn Y2 is DTY yarn, the elastic yarn Y3 is ATY yarn, and the bulkiness of the FDY yarn, DTY yarn, and ATY yarn is in ascending order from low to high.

[0014] Preferably, the reed-to-needle method in the low-bulky structure and the high-bulky structure of the warp-knitted elastic fabric that does not adhere to the body of the present application is the same needle-to-needle method, among which, a i =m j and b i =n j is.

[0015] Preferably, the wrapping codes of the low-bulky yarn Y1 and the high-bulky yarn Y2 of the warp-knitted elastic fabric that does not adhere to the body of the present application are both 1-0 / 2-3 / / or 0-1 / 2-1 / / or 1-0 / 1-2 / 2-3 / 2-1 / / , and the wrapping code of the elastic yarn Y3 is 0-2 / 3-1 / / or 1-0 / 1-2 / / or 1-0 / 1-2 / 2-3 / 2-1 / / .

[0016] Preferably, the loops through which the yarns of each reed run in the fabric body of the low-bulky yarn Y1, high-bulky yarn Y2, and elastic yarn Y3 of the warp-knitted elastic fabric that does not adhere to the body of the present application are one or any combination of an all-open structure, an all-closed structure, and an alternate open and closed structure.

Modes for Carrying Out the Invention

[0027] Hereinafter, specific examples will be combined with the drawings to clearly and completely describe the technical means in the examples of the present application and explain the technical means of the present application. Of course, the described examples are only part of the examples of the present application, not all of them. Based on the examples of the present application, all other examples obtained on the premise that those skilled in the art do not perform creative labor belong to the protection scope of the present application. Here, the examples of the present application are described with reference to the drawings, and similar element signs in the drawings represent similar elements.

[0028] The warp-knitted elastic fabric of the present application includes a fabric body presenting a warp-knitted structure. The fabric body includes at least a low-bulk yarn Y1, a high-bulk yarn Y2, and an elastic yarn Y3. The low-bulk yarn Y1, the high-bulk yarn Y2, and the elastic yarn Y3 are knitted in a guide-bar-through way to form the fabric body. Both the low-bulk yarn Y1 and the high-bulk yarn Y2 are located on the surface layer of the fabric body, and they are arranged at intervals. The low-bulk yarn Y1 forms a low-bulk structure in the fabric body in a guide-bar-through way. The low-bulk structure forms a basic unit of passing a i not passing b i and circulates this throughout the width. The passing and not passing in one of the basic units are a i and b i which are represented by, where 1 ≤ a i ≤ 50, 1 ≤ b i ≤ 50. Among them, a i represents a guide needle for passing the yarn, and b i represents a guide needle for not passing the yarn. The circulation unit is formed by combining at least one and at most no more than 10 different basic units into one circulation unit and is repeated along the width direction throughout the width. The low-bulk yarn Y2 forms a high-bulk structure in the fabric body in a guide-bar-through way. The high-bulk structure forms a basic unit of not passing m j passing n j and circulates this throughout the width. The passing and not passing in one of the basic units are m j and n j which are represented by, where 1 ≤ m j ≤ 50, 1 ≤ n j ≤ 50. Among them, m j represents a guide needle for not passing the yarn, and n jrepresents a guide needle for passing a thread. The circulation unit is formed by combining at least one and at most no more than 10 different basic units into one circulation unit, and is repeated along the entire width in the width direction. The elastic thread Y3 forms an elastic structure in the fabric body in the way of passing through the reed threads. The elastic structure is formed by passing the elastic thread Y3 through all the reed threads. Both the low-bulk thread Y1 and the high-bulk thread Y2 form a convex structure on the surface of the fabric body that touches the skin. The warp-knitted elastic fabric that does not stick to the body of the present application includes a fabric body presenting a warp-knitted structure. The fabric body includes at least three types of threads: a low-bulk thread Y1, a high-bulk thread Y2, and an elastic thread Y3. Both the low-bulk thread Y1 and the high-bulk thread Y2 are located on the surface layer of the fabric body, and the two are arranged at intervals. By combining with the well-known prior art that the smoother the surface, the flatter it becomes as the moisture content increases, and the stronger the force of sticking to the skin, in the present application, the feature that the high-bulk thread Y2 has higher water absorption than the low-bulk thread Y1 is utilized, and combined with the structure of arranging the two at intervals, the moisture content of the low-bulk thread Y1 is effectively reduced, so that the low-bulk thread Y1 gets wet and weakens the force of sticking to the skin, making the present application not stick to the body. At the same time, by utilizing the bulkiness and curling property of the high-bulk thread Y2 to make the contact with the skin a point contact, the contact area is reduced, and it can be seen that the performance of not sticking to the body and the air permeability of the present application are further enhanced. Also, in the present application, the fabric body of the present application absorbs water from the skin by the high-bulk thread Y2, and the moisture is transmitted to the low-bulk thread Y1 by capillary action, thereby transmitting and diffusing the moisture and accelerating quick drying. The structure of arranging the low-bulk thread Y1 and the high-bulk thread Y2 of the present application at intervals greatly enhances the ability of moisture absorption and quick drying, and at the same time greatly reduces the effect of the force of sticking to the skin, giving the present application excellent performance of not sticking to the body. At the same time, with the combination of the three types of threads, namely the low-bulk thread Y1, the high-bulk thread Y2, and the elastic thread Y3 of the present application, while ensuring that the fabric body has elasticity, the formed convex structure forms a micro high-low uneven space and more gaps between the threads, improving the air circulation and enhancing the air permeability of the fabric.

[0029] From what has been described above, the warp knitted elastic fabric that does not adhere to the body of the present application not only does not adhere to the body, but also has functions such as good air permeability, quick moisture absorption and drying, and the edges are not easily rounded. The warp knitted elastic fabric that does not adhere to the body of the present application is provided with characteristics such as a large opening degree, good recovery property, and can be arbitrarily cut. When worn, it is refreshingly comfortable and does not stick to the skin, and always keeps the surface of the human skin smooth and comfortable. Therefore, it has high practicality and obvious effects, and is very suitable for making clothes that come into contact with the skin such as underwear, T-shirts, trousers, and shirts. It can meet people's needs for comfort, functionality, and practicality, has a wide range of applications, and has good market prospects, economic, and social effects and benefits.

[0030] In order to further improve the non-adhesion to the body and air permeability of the present application, preferably, the convex structure of the warp knitted elastic fabric that does not adhere to the body of the present application presents a dot shape or a linear shape. The dot-shaped or linear convex structure not only effectively reduces the adhesiveness in contact with the skin, but also further enhances the air circulation, increases the air permeability of the fabric, and makes the wearing comfort moderately comfortable.

[0031] The performance of not adhering to the body, having good air permeability, quick moisture absorption and drying, and the edges not being easily rounded of the present application is further improved. Preferably, the number ratio of the low-bulky yarn Y1 and the high-bulky yarn Y2 of the warp knitted elastic fabric that does not adhere to the body of the present application is between 1:3 and 3:1, and the yarn density ratio of the low-bulky yarn Y1 and the high-bulky yarn Y2 is between 0.5 and 3.5. More specifically, the yarn density ratio of the low-bulky yarn Y1 and the high-bulky yarn Y2 of the warp knitted elastic fabric that does not adhere to the body of the present application is between 0.9 and 1.2, and the yarn density of the low-bulky yarn Y1 or the high-bulky yarn Y2 is between 7 and 100 denier.

[0032] Preferably, the low-bulky yarn Y1 of the warp-knitted elastic fabric that does not adhere to the body of the present application is an FDY yarn, the high-bulky yarn Y2 is a DTY yarn, the elastic yarn Y3 is an ATY yarn, and the bulkiness of the FDY yarn, DTY yarn, and ATY yarn is in ascending order from low to high. The present application has a knitted fabric structure, and a high-bulky yarn (DTY yarn) and a low-bulky yarn (FDY yarn) are adopted in the arrangement of the yarns, and they are arranged at intervals. The smooth surface becomes flatter as the moisture content increases, and the force of sticking to the skin becomes stronger. Therefore, since the water absorption of the DTY yarn is faster than that of the FDY yarn, the moisture content of the FDY yarn is reduced, thereby weakening the force of the FDY yarn sticking to the skin after getting wet. Due to the bulkiness and curl of the DTY yarn, the contact with the skin is in a point contact, so the contact area is small. The DTY yarn absorbs water from the skin and guides it onto the FDY yarn by capillary action for transmission and diffusion, thereby accelerating quick drying. Therefore, the structure with an interval between the FDY yarn and the DTY yarn helps with moisture absorption and quick drying and a reduction in the force of sticking to the skin. Furthermore, the FDY yarn and the DTY yarn form a very obvious microscopic high and low uneven space and more pores between the yarns, further improving the air circulation performance and enhancing the breathability of the fabric. More specifically, the reed-to-needle method in the low-bulky structure and the high-bulky structure of the warp-knitted elastic fabric that does not adhere to the body of the present application is the same pair of needles, among which a i =m j and b i =n j is. Among them, FDY is the abbreviation of Fully drawn yarn in English and is translated as "fully drawn yarn" in Chinese. DTY is the abbreviation of Draw texturing yarn in English and is translated as "drawn textured yarn" in Chinese. ATY is the abbreviation of Air textured yarn in English and is translated as "air textured yarn" in Chinese.

[0033] Preferably, the lapping codes of the low-bulky yarn Y1 and the high-bulky yarn Y2 of the warp-knitted elastic fabric that does not adhere to the body of the present application are both 1-0 / 2-3 / / or 0-1 / 2-1 / / or 1-0 / 1-2 / 2-3 / 2-1 / / , and the lapping code 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, for the low-bulk yarn Y1, high-bulk yarn Y2, and elastic yarn Y3 of the warp-knitted elastic fabric that does not adhere to the body of the present application, the loops through which the yarns of each reed run in the fabric body are one or any combination of an all-open structure, an all-closed structure, and an alternate open and closed structure.

[0035] Preferably, the fabric body of the warp-knitted elastic fabric that does not adhere to the body of the present application exhibits a single-sided jacquard or double-sided jacquard structure.

[0036] Preferably, the bottom surface of the fabric body of the warp-knitted elastic fabric that does not adhere to the body of the present application exhibits a fleece structure. By forming a napped effect with the fleece structure, the touch of the fabric of the present application is improved. Furthermore, the fleece structure can be obtained by a napping treatment process.

[0037] Preferably, the low-bulk yarn Y1 of the warp-knitted elastic fabric that does not adhere to the body of the present application is preferably a chemical fiber yarn, and the high-bulk yarn Y2 of the present application is preferably a staple fiber yarn.

[0038] To further deepen the understanding of the detailed description of the application and its embodiments, hereinafter, the low-bulk yarn Y1, high-bulk yarn Y2, and elastic yarn Y3 are replaced with symbols well-known to those skilled in the art. That is, the low-bulk yarn Y1 is represented by yarn Y1, the high-bulk yarn Y2 is represented by yarn Y2, and the elastic yarn Y3 is represented by yarn Y3. Also, hereinafter, PA6 refers to nylon 6, FD is an abbreviation of full dull in English, which is translated as "full dull" in Chinese, and PU is an abbreviation of polyurethane in English, which is translated as "polyurethane" in Chinese.

[0039] Combining FIGS. 1 to 7 with Tables 1 and 2, the warp-knitted elastic fabric that does not adhere to the body to be applied will be described in more detail. Example 1: Using a 40-needle warp knitting machine, a i = m j = 1 and b i = n jSet it as =1, adopt PA6 25 / 34 FD FDY yarn for yarn Y1, the yarn passing method is one through and one empty, adopt PA6 25 / 34 FD DTY yarn for yarn Y2, the yarn passing methods are one empty and one through, and one through every other one, the structure is 1-0 / 2-3 / / (that is, the lapping code of yarn Y1 and yarn Y2), the yarn feeding amount is 1220 mm / rack, adopt PU 20D for yarn Y3, the head draw ratio is 100%, the structure is 0-2 / 3-1 / / , all through, and weave with the yarn feeding amount of 1300 mm / rack.

The specifications of the finished product obtained through a series of subsequent processes of washing - scheduling - dyeing - post - finishing are 160 cm * 145 g / m 2 It is.

[0042] Adopt the same moisture absorption and quick - drying post - treatment for the above - mentioned fabrics, and conduct tests on moisture absorption and quick - drying, one - way moisture induction, air permeability and the force of sticking to the skin for the above - mentioned fabrics.

[0043] Sampling: In this experiment, from a 50-yard roll of fabric, three 0.5-yard pieces of fabric were taken from the front, middle, and back sections. One piece was used for the moisture absorption and quick-drying test, one for the unidirectional moisture induction test, one for the air permeability test, and one for the test of the force of sticking to the skin.

[0044] Moisture absorption and quick-drying test: JIS L1907 was adopted. The moisture absorption and quick-drying tests were carried out on three pieces of fabric of one part of the samples, and the average value of the moisture absorption and quick-drying values of the three pieces of fabric was obtained as the moisture absorption and quick-drying value of the fabric.

[0045] Air permeability test: JIS L 1096 Method A was adopted. The air permeability test was carried out on three pieces of fabric of one part of the samples for the left, middle, and right of each piece of fabric, and the average value was obtained as the result of each air permeability value. The average value was obtained again for the air permeability values of the three pieces of fabric as the final air permeability value of the fabric.

[0046] Unidirectional moisture induction test: The measurement of AATCC 195 "Liquid Moisture Management Properties of Textile Fabrics" was carried out. The unidirectional moisture induction ability OWTC (one way transport capability) test was carried out on three pieces of fabric of one part of the samples, and the average value was obtained for the OWTC values of the three pieces of fabric as the OWTC value of the fabric.

[0047]

Table 1

[0048] Analyzing Table 1, the above-mentioned fabrics that adopted the same moisture absorption and quick-drying post-treatment all have good moisture absorption. The quick-drying property of DTY is slightly inferior to that of FDY. Example 1 and Comparative Example 2 have good moisture absorption and quick-drying properties. The unidirectional transmission performance of Comparative Example 2 is the best, from which it can be seen that the DTY yarn has better unidirectional transmission performance than the FDY yarn. In terms of air permeability, Example 1 has better performance. Overall, Example 1 is excellent in terms of moisture absorption and quick-drying properties and air permeability.

[0049] The test of the force to stick to the skin is as follows. Experimental equipment: Zwick tensile machine, 5N sensor, self-made friction coefficient meter, friction block (a smooth and cornerless copper block of 2×2 cm, the contact surface is uncoated) Sample: Vertical direction (L) & horizontal direction (W): 8×12 cm. Fold 1 cm inward from both ends in the 12 cm direction and stitch so that the effective distance in the middle is 8 cm, that is, 8×8 cm.

[0050] Test conditions: Water droplet amount: 0.2 mL (Drop to the center position of the sample and let it diffuse. The total penetration time is 30 seconds. Then, start timing from 0 minutes and test every 5 minutes.) Expected tension: 0.1 N Pre-tension speed: 50 mm / min Elongation speed: 200 mm / min Elongation displacement: 60 mm

[0051] Operation method: Straighten the stitching line (guarantee zero tension as much as possible), fix it on the friction coefficient meter, test directly in the dry state, and test after dripping water (counting) in the wet state. The friction block starts sliding from the edge of the 8×8 cm cloth piece, and takes the values at the positions where the sliding distance values are 30 mm, 40 mm, and 50 mm respectively. This experiment simulates the moisture environment between the skin and clothing after the human body sweats, and uses the frictional force measured in the wet state to represent the sticking force between the skin and the fabric after sweating. The force f to stick to the skin is f = f L +f W where f L is the frictional force in the vertical direction, and f W is the frictional force in the horizontal direction. In this experiment, mainly focus on the frictional force of the surface (Back Side) that sticks to the skin. Record the data of the force to stick to the skin at 0 minutes, 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, and 30 minutes after water droplet dripping and in the dry state. See Table 2.

[0052]

Table 2

[0053] To facilitate observation and analysis, the 50 mm position and the water droplet data within 30 minutes in Table 2 are presented as a transition diagram as shown in Figure 1.

[0054] From Figure 1, it can be seen that after the water droplets are dropped, the force of adhesion to the skin suddenly increases significantly. As the water gradually penetrates from the surface in contact with the skin and diffuses to other surfaces, the adhesion force of the surface in contact with the skin gradually decreases. When it reaches a completely dry state, the adhesion force returns to the initial state with the minimum value. In Example 1 and Comparative Example 1, within 30 minutes after the water droplet state, the force of adhesion to the skin is lower than that in Comparative Example 1. Therefore, Example 1 has a smaller adhesion force in the wet state and a higher effect of not wetting the body.

[0055] From the above, as a result of conducting tests on the fabric for moisture absorption and quick drying, breathability, one-way moisture induction ability, and adhesion to the skin, it can be seen that Example 1 is excellent in performance in each item and has the effect of not adhering to the body due to good moisture absorption and quick drying properties and breathability.

[0056] Example 2: As shown in Figure 3, a i = m j = 1 and b i = n j = 1. Yarn Y1 is FDY yarn, the threading method is 1 through 1 empty, yarn Y2 is DTY yarn, the threading method is 1 empty 1 through, the healds of yarn Y1 and yarn Y2 are the same pair of needles, the lapping code of yarn Y1 and yarn Y2 is 1-0 / 2-3 / / , yarn Y3 is spandex, the yarn is all-through, and the lapping code is 1-0 / 1-2 / / .

[0057] Example 3: As shown in Figure 4, yarn Y1 is FDY yarn, the threading method is 1 through 1 empty, yarn Y2 is DTY yarn, the threading method is 1 empty 1 through, the healds of yarn Y1 and yarn Y2 are the same pair of needles, the lapping code of yarn Y1 and yarn Y2 is 0-1 / 2-1 / / , yarn Y3 is spandex, the yarn is all-through, and the lapping code is 1-0 / 1-2 / / .

[0058] Example 4: As shown in Figure 5, thread Y1 is FDY thread, the threading method is one through and one empty, thread Y2 is DTY thread, the threading method is one empty and one through, the heddles of thread Y1 and thread Y2 are the same pair of needles, the lapping code of thread Y1 and thread Y2 is 1-0 / 1-2 / 2-3 / 2-1 / / , thread Y3 is spandex, the thread is all-through, and the lapping code is 1-0 / 1-2 / 2-3 / 2-1 / / .

[0059] Example 5: As shown in Figure 6, a i =m j =1 and b i =n j =2, thread Y1 is FDY thread, the threading method is one through and two empty, thread Y2 is DTY thread, the threading method is one empty and two through, the heddles of thread Y1 and thread Y2 are the same pair of needles, the lapping code of thread Y1 and thread Y2 is 1-0 / 2-3 / / , thread Y3 is spandex, the thread is all-through, and the lapping code is 0-2 / 3-1 / / .

[0060] Example 6: As shown in Figure 7, a i =m j =2 and b i =n j =3, thread Y1 is FDY thread, the threading method is two through and three empty, thread Y2 is DTY thread, the threading method is two empty and three through, the heddles of thread Y1 and thread Y2 are the same pair of needles, the lapping code of thread Y1 and thread Y2 is 1-0 / 2-3 / / , thread Y3 is spandex, the thread is all-through, and the lapping code is 0-2 / 3-1 / / .

[0061] Example 7: Based on Example 3, yarn Y1 is changed to chemical fiber, the threading method is one-through-one-empty, yarn Y2 is changed to short fiber, the threading method is one-empty-one-through, the heddles of yarn Y1 and yarn Y2 are the same pair of needles, the lapping codes of yarn Y1 and yarn Y2 are 0-1 / 2-1 / / , yarn Y3 is spandex, all the yarns are threaded through, and the lapping code is 1-0 / 1-2 / / (the structure is the same as that of Example 3). By utilizing the characteristics that the amount of fibers and the amount of gaps between fibers of the short fiber yarn are such that the water absorption of the Y2 short fiber yarn is faster than that of the Y1 chemical fiber, and combining with the structure where the two are arranged at intervals, the water content of the chemical fiber Y1 is effectively reduced, and the sticking force of the chemical fiber Y1 to the skin after wetting is decreased. At the same time, the short fiber Y2 absorbs water from the skin and transfers the water to the chemical fiber Y1 by capillary action, and the transmission and diffusion of the water accelerate quick drying. Also, when the short fiber Y2 and the chemical fiber Y1 are arranged in parallel or interwoven, the degree of tight binding is lower than that of the binding between chemical fibers, so the fabric has more gaps between yarns, further enhancing the air permeability and increasing the breathability of the fabric.

[0062] Example 8: Based on Example 6, yarn Y1 is changed to chemical fiber, the threading method is two-through-three-empty, yarn Y2 is changed to short fiber, the threading method is two-empty-three-through, the heddles of yarn Y1 and yarn Y2 are the same pair of needles, the lapping codes of yarn Y1 and yarn Y2 are 1-0 / 2-3 / / , yarn Y3 is spandex, all the yarns are threaded through, and the lapping code is 0-2 / 3-1 / / (the structure is the same as that of Example 6).

[0063] For the yarn Y3 of the present application, spandex or polyolefin is preferred.

[0064] Also, the weaving methods related to the present application are all existing technologies, and the structure is limited using known methods. The materials related to the present application are existing technologies and are well-known to those skilled in the art, so they will not be described in detail here.

[0065] For those skilled in the art, the present application is not limited to the details of the above exemplary embodiments, and it is obvious that the present application can be implemented in other specific forms without departing from the gist or basic features of the present application. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is limited by the claims rather than the above description. Thus, all changes within the meaning and scope of the equivalent requirements of the claims are intended to be included in the present application. Any reference numerals in the claims shall not be construed as limiting the claims concerned. At the same time, since what is disclosed above is only a preferred embodiment of the present application, naturally, the scope of the rights of the present application cannot be limited thereby. Therefore, equivalent changes based on the claims of this patent are also intended to fall within the scope covered by the present application.
