Description

Technical Field

[0001] This application relates to the textile field, specifically to a warp-knitted mesh fabric. Background Technology

[0002] Warp-knitted mesh fabrics are widely used in clothing, footwear, and sports textiles due to their excellent breathability and lightweight properties. Existing warp-knitted mesh fabrics typically employ a combination of different warp-knitting structures to create a fabric structure with multiple mesh openings, meeting the fabric's requirements for breathability, elasticity, and structural stability.

[0003] As the requirements for fabric breathability and wearing comfort increase, some warp-knitted mesh fabrics use larger mesh sizes to improve air circulation. However, with larger mesh sizes, the yarn span near the mesh area also increases accordingly. Some yarns are prone to forming longer floats or relatively loose yarn segments, which can easily shift, snag, or deform locally during use such as stretching and friction, affecting the structural stability of the fabric.

[0004] In addition, during exercise or in high-temperature environments, the fabric is prone to becoming damp and softening after absorbing sweat. The yarns near the mesh area tend to adhere to the skin, reducing the original breathability and creating a sticky feeling, thus affecting the wearing comfort of the warp-knitted mesh fabric. Summary of the Invention

[0005] In view of the above problems, this application provides a warp-knitted mesh fabric to improve the yarn structure stability and wet skin contact problem of existing warp-knitted mesh fabrics under larger mesh conditions.

[0006] To achieve the above objectives, the inventors provide a warp-knitted mesh fabric, comprising multiple wales of loops, multiple mesh openings formed by the wales of loops, and multiple transverse extension lines;

[0007] At least a portion of the boundary of the mesh is formed by a planar loop structure;

[0008] The transverse extension line crosses at least two of the coil longitudinal rows along the arrangement direction of the coil longitudinal rows, and the two ends of each transverse extension line are respectively connected to the warp loop structure located on both sides thereon;

[0009] The transverse extension lines arranged adjacent to each other along the warp direction are staggered, with some of the transverse extension lines located in the hollow area of ​​the mesh and some of the transverse extension lines located at the corresponding positions of the ring pillars of the warp hexagonal structure.

[0010] Unlike existing technologies, the above-mentioned technical solution constructs at least a portion of the mesh boundary using a warp loop weave, and allows the transverse extension lines to cross at least two loops, with their ends connected to the warp loop weave structures on both sides. This ensures that the transverse extension lines crossing the mesh area maintain a stable connection through the loop structures on both sides. Even with increased mesh size, the transverse extension lines maintain a constrained structure at both ends, reducing the formation of loose, free-floating yarns in the mesh area and thus improving the structural stability of the mesh area.

[0011] Meanwhile, the adjacent transverse extension lines along the warp direction are staggered, with some transverse extension lines located in the hollow areas of the mesh and others located at the corresponding positions of the loops in the hexagonal weave. This prevents the transverse extension lines on the skin-contact side from being concentrated in a continuous arrangement on the same plane. After the fabric absorbs moisture, the staggered transverse extension lines can form dispersed contact and support areas at different locations, reducing the amount of wet fabric adhering to the skin and allowing the hollow areas of the mesh to retain some air circulation space, thereby improving the skin-contact feel and breathability of the fabric when wet.

[0022] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0023] In existing warp-knitted mesh fabrics, a combination of chain knitting and modified warp pile structures can be used to create a mesh fabric structure. See also Figure 1 and Figure 2 The red chain weave 2 mainly forms continuous loops along their respective loop warp, with the chain loops in adjacent loop warp being independent of each other, mainly forming a loop structure extending along the warp direction; the blue variable warp pile weave 1 moves laterally between adjacent loop warp, and some of its yarn segments can span multiple loop warp.

[0024] The transverse yarn segment formed by the variation in pile weave 1 can laterally span two loop warp, that is, span two needle positions. Since the chain weave 2 itself is mainly continuously interlocked within the same loop warp, there is no transverse yarn connection between adjacent chain warp to restrict the middle of the transverse yarn segment. Therefore, the transverse yarn segment is mainly held in the fabric by the corresponding loop positions at its two ends, and its middle area has a relatively large degree of freedom of movement.

[0025] When the mesh is further enlarged by adjusting the weave structure, the length of the transverse yarn segments within the mesh area increases accordingly. At this point, if independent chain weaves are still used as the main loop-forming basis, the middle of the transverse yarn segments lacks further weave restraint, easily forming relatively free long floats. When the fabric deforms during stretching, friction, or wear, these long floats are prone to displacement, curling, or snagging; after absorbing sweat, as the yarn and fabric soften, the longer floats can also adhere to the skin, affecting the original ventilation space of the mesh.

[0026] Based on the above, this embodiment no longer relies on the braided chain structure 2 that extends independently along the longitudinal direction of each coil to form the main constraint of the above-mentioned mesh area, but instead re-establishes the connection relationship between the mesh boundary and the transverse yarn.

[0027] Please refer to Figures 3 to 5This embodiment provides a warp-knitted mesh fabric, including multiple loops, multiple mesh openings formed by the loops, and multiple transverse extension lines 4; at least a portion of the boundaries of the mesh openings are formed by a warp knitting loop 3; the transverse extension lines 4 span at least two loops along the arrangement direction of the loops, and the two ends of each transverse extension line 4 are respectively connected to the warp knitting loop 3 located on both sides thereon; the transverse extension lines 4 arranged adjacent to each other along the warp direction are staggered, some of the transverse extension lines 4 are located in the hollow area of ​​the mesh openings, and some of the transverse extension lines 4 are located at the corresponding positions of the loop posts of the warp knitting loop 3.

[0028] The weft yarn consists of multiple loops interlocked along the warp direction, arranged along the width of the fabric. Adjacent weft yarn rows and their corresponding yarn structures together form multiple mesh openings, each with a hollow area for air circulation.

[0029] At least a portion of the mesh boundary is formed by a warp loop weave 3. In one embodiment, a loop structure of both positive and negative warp pads can be used to form at least a portion of the boundary around the mesh. Compared to independently braided loop warps, the warp loop weave 3, while forming loop warps, allows the yarn movement to establish corresponding loop connections between adjacent positions, thereby forming the boundary skeleton around the mesh.

[0030] The transverse extension line 4 extends along the arrangement direction of the multiple coil longitudinal rows, and its extension direction intersects with the warp extension direction of the coil longitudinal rows. Each transverse extension line 4 spans at least two coil longitudinal rows, and the two ends of the transverse extension line 4 are respectively connected to the corresponding warp flat loops 3 on its left and right sides.

[0031] Specifically, one end of the transverse extension line 4 can connect with the corresponding warp loop on one side of the mesh, and the other end can connect with another warp loop on the other side of the mesh. The corresponding connection position can be located at the loop post, loop arc, or loop formation position adjacent to the loop post and loop arc of the warp loop structure 3. Thus, although the transverse extension line 4 crosses the corresponding mesh area, both ends of it remain within the loop formation structure of the fabric, rather than forming a free yarn segment independent of the structures on both sides.

[0032] When the mesh size increases, the main change is in the size of the hollow area formed between adjacent warp loop boundaries; the connection between the two ends of the transverse extension line 4 and the corresponding warp loop weave 3 is still maintained. Therefore, even if the transverse extension line 4 spans a large mesh area, its two ends are still located in the loop weave on both sides, which reduces the possibility of the transverse yarn segment becoming completely free or sticking out of the weave structure.

[0033] Furthermore, the transverse extension lines 4 arranged adjacent along the warp direction are staggered from each other, rather than continuously overlapping at the same position. Some of the transverse extension lines 4 are located in the hollow area of ​​the mesh, and other transverse extension lines 4 are located at the corresponding positions of the ring pillars of the warp hexagonal weave 3.

[0034] In other words, when observing the transverse extension lines 4 sequentially along the warp direction, one row of transverse extension lines 4 can cross the hollow, breathable area of ​​the mesh, while another adjacent row of transverse extension lines 4 corresponds to the loop position of the warp flat loop weave 3. The positions of the two adjacent transverse extension lines 4 on the fabric plane are staggered, so that a large area of ​​flat yarn layer formed by the continuous overlap of multiple transverse extension lines 4 will not be formed on the skin-contact side.

[0035] Therefore, in this embodiment, the lateral extension line 4 not only serves as the lateral connection between adjacent looped areas, but its staggered arrangement also forms a discontinuous contact structure on the skin-contact side. The lateral extension line 4 spanning the hollow area and the lateral extension line 4 at the corresponding loop position occupy different organizational positions, giving the skin-contact side of the fabric a structural basis with alternating linear and looped positions.

[0036] Furthermore, the plurality of the transverse extension lines 4 extend along the fabric width direction and are arranged at intervals along the warp direction.

[0037] Specifically, each transverse extension line 4 is generally laid out along the width of the fabric. The arrangement direction of the transverse extension lines 4 intersects with the warp-extending loops and can be basically perpendicular to the warp-extending loops. Multiple transverse extension lines 4 are arranged sequentially along the warp direction, and a predetermined spacing is maintained between adjacent transverse extension lines 4.

[0038] By adopting the above arrangement, the transverse extension lines 4 can be continuously distributed across multiple mesh areas, rather than concentrated in a localized area. Simultaneously, maintaining appropriate space between adjacent transverse extension lines 4 prevents the transverse yarns from excessively covering the hollow areas of the mesh.

[0039] Furthermore, the plurality of the lateral extension lines 4 are arranged at equal intervals along the longitudinal direction.

[0040] Specifically, each adjacent transverse extension line 4 forms a basically the same spacing along the warp direction, so that the transverse extension lines 4 form a relatively regular periodic arrangement throughout the entire fabric.

[0041] By setting equal intervals, the distribution of the transverse connection positions and the skin-contact yarn positions corresponding to each transverse extension line 4 can be made more uniform, reducing the structural differences caused by excessively dense or sparse local transverse extension lines 4, and helping to maintain the uniformity of the fabric structure.

[0042] Furthermore, of the two adjacent transverse extension lines 4 along the warp direction, one transverse extension line 4 spans the hollow region of the mesh, and the other transverse extension line 4 is located at the corresponding position of the loop post of the warp flat loop structure 3.

[0043] Specifically, the transverse extension line 4 located in the hollow area of ​​the mesh can be set in the middle or near the middle of the hollow area of ​​the mesh; another transverse extension line 4 adjacent to it along the warp direction is set at the corresponding position of the ring column of the warp hexagonal loop structure 3.

[0044] The corresponding position of the loop post mentioned here refers to the position of the projection of the transverse extension line 4 on the fabric plane corresponding to the position of the loop post through the flat loop, rather than the transverse extension line 4 passing through the hollow area of ​​the mesh being in the same position.

[0045] Therefore, there is not only a longitudinal spacing between the two adjacent transverse extension lines 4, but also corresponding to the hollow area of ​​the mesh and the circled area of ​​the mesh boundary, thus further forming a misaligned organizational structure.

[0046] Furthermore, the transverse extension lines 4 located in the hollow region of the mesh and the transverse extension lines 4 located at the corresponding positions of the loop posts of the warp helix structure 3 are arranged alternately along the warp direction.

[0047] Specifically, the two types of transverse extension lines 4 can be alternately set along the warp direction. That is, after the transverse extension line 4 that crosses the hollow area of ​​the mesh, a transverse extension line 4 corresponding to the position of the ring post is set, and then a transverse extension line 4 that crosses the hollow area of ​​the next mesh is set. This process is repeated along the warp direction to form an interlaced structure.

[0048] Therefore, the misalignment between adjacent transverse extension lines 4 does not only exist in individual areas, but can be continuously distributed along the warp direction of the fabric, so that a relatively uniform interlaced yarn structure is formed on the skin side.

[0049] Under dry conditions, the transverse extension lines 4 spanning the hollow areas of the mesh and the transverse extension lines 4 corresponding to the loop positions are in different organizational positions, forming an overhead structure that combines linear positions with dotted or locally looped positions. When human skin comes into contact with the fabric, the entire fabric surface is not continuously attached to the skin; adequate air circulation space can still be maintained between the transverse extension lines 4 and in the hollow areas of the mesh.

[0050] Under wet conditions, the yarn absorbs sweat and undergoes a certain degree of radial and transverse swelling, causing corresponding changes in the diameter, tension, and contact state of the transverse extension lines 4. Because adjacent transverse extension lines 4 are in staggered positions, when the fabric is compressed by the human body, the transverse extension lines 4 at different locations can form contact and abutment positions, creating multiple dispersed support points on the skin-contact side, rather than the entire wet fabric surface continuously adhering to the skin.

[0051] Therefore, even as the fabric becomes softer after absorbing moisture, the staggered transverse extension lines 4 can still maintain the gap between the fabric and the skin to a certain extent. At the same time, air circulation paths are still maintained between the transverse extension lines 4 and in the hollow areas of the mesh, which is conducive to the exchange of air between the skin-contact side and the mesh.

[0052] Furthermore, the warp-knitted mesh fabric includes an inner layer on the skin-contact side and an outer layer on the inner layer away from the skin-contact side, the transverse extension line 4 is formed in the inner layer, and the outer layer includes the warp loop structure 3 that constitutes at least a portion of the boundary of the mesh.

[0053] Specifically, the inner layer is the side of the warp-knitted mesh fabric that faces the skin when in use, and the outer layer is located on the side of the inner layer that faces away from the skin. Lateral extension lines 4 are formed in the inner layer, allowing them to directly form the yarn structure on the skin-contact side. The outer layer includes a warp loop weave 3, with corresponding warp loop weave 3 forming at least a portion of the mesh boundary.

[0054] It should be noted that the inner and outer layers described in this embodiment are mainly used to describe the relative positions of different yarn structures in the fabric thickness direction and the direction of use, and do not necessarily indicate that the inner and outer layers are two independent fabric layers that are woven separately and then composited.

[0055] Conversely, in this embodiment, the inner and outer layers can be integrally formed in the same warp knitting process, so that the inner layer structure forming the transverse extension line 4 and the outer layer structure forming the mesh-related boundary establish a nested relationship at the corresponding looping positions.

[0056] Furthermore, the inner layer is woven from a first inner Jacquard comb and a second inner Jacquard comb, with the first inner Jacquard comb and the second inner Jacquard comb forming the transverse extension line 4; the outer layer is woven from a first outer Jacquard comb and a second outer Jacquard comb.

[0057] In one specific embodiment, the first inner Jacquard comb and the second inner Jacquard comb correspond to JB1.1 and JB1.2, respectively, and the first outer Jacquard comb and the second outer Jacquard comb correspond to JB2.1 and JB2.2, respectively.

[0058] JB1.1 and JB1.2 are used to weave the inner layer located on the skin side and form the aforementioned transverse extension line 4 during the weaving process; JB2.1 and JB2.2 are used to weave the outer layer and form the surface fabric and the organizational structure related to the mesh.

[0059] In this embodiment, four Jacquard guide bars (JB1.1, JB1.2, JB2.1, and JB2.2) are actually used in the weaving of the fabric structure described above. While the warp knitting equipment itself can have a machine structure capable of equipping more guide bars, this embodiment actually uses four Jacquard guide bars to form the fabric structure described above.

[0060] Furthermore, the yarns of the inner layer and the yarns of the outer layer interlock during the looping process, and the inner layer and the outer layer form an integral woven structure.

[0061] Specifically, the inner layer yarns formed by JB1.1 and JB1.2 and the outer layer yarns formed by JB2.1 and JB2.2 interlock with each other in predetermined positions during the warp knitting process, so that the inner and outer layers are formed synchronously on the same fabric body, rather than being connected by bonding, sewing or other composite methods after they are woven independently.

[0062] By forming an interlocking relationship between the inner and outer yarns during the looping process, the inner transverse extension line 4 and the outer mesh structure can maintain a predetermined positional relationship, reducing the possibility of relative slippage or misalignment between the inner and outer layers, and forming an integrated jacquard composite fabric.

[0063] Furthermore, the lateral extension line 4 spans 2 to 4 of the coil longitudinal rows.

[0064] Specifically, a single transverse extension line 4 can span 2, 3, or 4 coil longitudinal rows, with 3 coil longitudinal rows being preferred.

[0065] The number of loops that the transverse extension line 4 crosses can be set according to the transverse size of the mesh and the required transverse extension distance. When the transverse extension line 4 crosses fewer loops, the transverse coverage is relatively limited; when the transverse extension line 4 crosses too many loops, the length of the cross section increases further, which may increase the probability of yarn friction, pilling, or snagging.

[0066] Therefore, in this embodiment, the transverse extension line 4 is set to span 2 to 4 coil longitudinal rows, which achieves a good balance between the transverse extension range and the stability of the fabric surface. Spanning 3 coil longitudinal rows can be considered a preferred configuration. Existing supplementary materials also clearly define 2 to 4 coil longitudinal rows as the specific span range of the transverse extension line 4.

[0067] Furthermore, the transverse extension line 4 is formed by a variable warp weave 1.

[0068] Specifically, the corresponding Jacquard comb forming the inner layer uses a change in the warp weave 1 to transversely pad the yarn between multiple loops, so that the corresponding yarn forms the aforementioned transverse extension line 4 during the transverse movement.

[0069] In a specific organizational form, JB1.1 and JB1.2 are used to form the inner layer of the variable warp pile structure 1, and the corresponding padding yarn numbers can be:

[0070] 1-0 / 1-2 / / ,1C1。

[0071] Through the aforementioned changes in the weft motion, the inner layer yarn can be moved laterally between different loop warp rows, forming a lateral extension line 4 with a predetermined span between adjacent loop positions.

[0072] Unlike the traditional "chain stitch + variable warp pile" weave, this embodiment does not have the transverse yarn segments generated by the variable warp pile attached only to the independent chain stitch wale. Instead, the two ends of the transverse extension line 4 are connected to the warp loop weave 3 on both sides of the mesh. Therefore, even if the variable warp pile weave 1 that can generate transverse needle crossing movement is used, the constraint state of its transverse yarn segments in the entire fabric is different.

[0073] In a specific outer layer weave configuration, JB2.1 and JB2.2 can form a warp-satin weave, and the corresponding padding yarn numbers can be:

[0074] 1-2 / 1-0 / / ,1C1。

[0075] The corresponding location in the outer layer can also be treated with deficient tissue, and the deficient tissue circulation can be as follows:

[0076] 1-0 / 2-2 / / .

[0077] Through the above-mentioned missing padding cycle, missing padding sections can be periodically formed during the weaving process, and hollow areas in the mesh can be formed in conjunction with the corresponding open-cut positions.

[0078] In other words, this embodiment can form the mesh through the interweaving of the warp loop weave 3, the warp satin weave, the missing pad area, and the open loop area, while the transverse extension line 4 crosses the corresponding loop longitudinally and remains connected to the loop structure on both sides of the mesh. Therefore, when enlarging the mesh, it is not necessary to rely on forming a longer unrestrained yarn segment to obtain the hollow area; the desired mesh can be formed while maintaining the interweaving connection at both ends of the transverse extension line 4.

[0079] In terms of yarn configuration, JB1.1 and JB1.2 can use 40D / 48F polyester moisture-wicking and quick-drying yarn to weave the inner layer. After the moisture-wicking and quick-drying yarn forms the transverse extension line 4 on the skin-contact side, when sweat comes into contact with the transverse extension line 4, it can diffuse laterally along the capillary path formed by the yarn itself and between adjacent yarns.

[0080] JB2.1 and JB2.2 are used to form the outer layer, which can be woven from ordinary DTY yarn and polyester moisture-wicking quick-drying yarn. For example, 30D / 36F DTY yarn can be used in combination with 40D / 48F polyester moisture-wicking quick-drying yarn to form the outer layer structure.

[0081] Four jacquard combs work together during the loop-forming process, with the inner and outer yarns interlocking to form a jacquard composite structure integrating the inner and outer layers.

[0082] It should be noted that the above-mentioned yarn specifications such as 40D / 48F and 30D / 36F, as well as the specific combination of moisture-wicking quick-drying yarn and DTY yarn, are one specific implementation method and can be adjusted according to the fabric's intended use, weight, softness, and required moisture-wicking performance.

[0083] The moisture absorption and drying performance of this embodiment does not rely solely on the yarn material itself. The transverse extension lines 4 are continuously distributed along the transverse direction of the fabric, which can form a transversely extending moisture transfer path after sweat comes into contact with the skin, allowing local sweat to diffuse from the contact point to multiple surrounding areas, reducing the situation where moisture is concentrated in a single area.

[0084] After moisture diffuses along the transverse extension line 4, its distribution area in the fabric increases, and the corresponding effective evaporation area also increases. At the same time, the adjacent transverse extension lines 4 are staggered, retaining multiple non-continuous contact positions and air gaps on the skin-contact side. Air can flow through the hollow areas of the mesh and the spaces between the transverse extension lines 4, so that moisture diffusion and air convection work together.

[0085] Especially under humid conditions, after the yarn absorbs moisture and swells radially and laterally, the staggered transverse extension lines 4 can form contact, abutment, and support at multiple different positions, making it difficult for the fabric to adhere continuously to the human skin even after it has absorbed moisture and softened. Sweat mainly adheres to and is transferred within the corresponding yarn structure, while the hollow areas of the mesh and the transverse extension lines 4 can still maintain a certain amount of air circulation space.

[0086] Therefore, this embodiment does not solve the problem of wet comfort by simply improving the moisture absorption and quick-drying properties of the yarn itself, but rather makes the yarn material properties and the warp knitting structure work together: the transverse extension lines 4 provide a transverse path for moisture to spread, the flat loop weave 3 maintains the structural stability of the mesh boundaries and the ends of the transverse extension lines 4, and the staggered arrangement of adjacent transverse extension lines 4 forms a dispersed contact structure on the skin side, thereby forming a synergistic relationship between mesh breathability, yarn structure stability and wet skin-friendly performance.

[0087] From the perspective of overall organization, this implementation eliminates the chain structure that mainly undertakes the longitudinal looping function in the traditional scheme, and makes the mesh boundary adopt the warp flat looping structure 3. The two ends of the transverse extension line 4 that crosses multiple loops are respectively connected to the warp flat looping structure 3 on both sides, so that the warp looping structure and the transverse yarn are connected in the same mesh area to form a cooperation. At the same time, by setting the transverse extension line 4 that passes through the hollow area of ​​the mesh and the transverse extension line 4 at the corresponding loop post position to be staggered along the warp, the transverse yarn forms a discontinuous and staggered arrangement on the skin side.

[0088] Therefore, even with a large mesh size, the transverse extension lines 4 can still maintain a stable organizational relationship between the two ends and the loop structure, reducing the possibility of forming isolated free long floats. After the fabric absorbs sweat, the misaligned transverse extension lines 4 can form support and retain air gaps at different positions, so that the fabric has good mesh breathability while taking into account the structural stability of the mesh area and the comfort of wearing it in wet conditions.

[0089] In summary, this application reorganizes the connection between the mesh boundaries and the transverse extension yarns, enabling the mesh area to have a larger hollow, breathable space while preventing the yarns crossing the mesh from being in a relatively free state. Simultaneously, the staggered distribution of the transverse extension yarns 4 on the skin-contact side creates a dispersed support structure in a wet state. Specifically, multiple loop warps form the main body of the fabric along the warp direction, and adjacent loop warps together form multiple meshes. At least part of the mesh boundaries are constructed using a warp loop weave 3. The transverse extension yarns 4 cross at least two loop warps along the arrangement direction of the loop warps, with their ends connecting to the warp loop weave 3 located on both sides. Thus, although the transverse extension yarns 4 cross the mesh area, their ends enter the corresponding loop weave structures to form a stable structural connection, unlike the state where relatively free long floats easily form when crossing the middle of the yarn segment when relying solely on the longitudinal chain weave structure 2. Even with an increased hollow area in the mesh, the connection between the transverse extension line 4 and the two sides of the warp loop weave 3 can still be maintained, thus maintaining the stability of the mesh edge and the weave across the yarn under larger mesh conditions.

[0090] Furthermore, this application does not arrange multiple transverse extension lines 4 continuously at the same position on the skin-contact side, but rather staggers adjacent transverse extension lines 4 along the warp direction. Some transverse extension lines 4 cross the hollow area of ​​the mesh, while others are located at the corresponding positions of the loop posts in the warp-knit weave 3, and can be arranged alternately along the warp direction. Thus, a discontinuous contact structure is formed on the skin-contact side, composed of transverse yarn segments at different positions and loop positions. In the dry state, a certain amount of space can be formed between the transverse extension lines 4 and in the mesh area; in the wet state, the yarn absorbs moisture and undergoes radial and transverse swelling. The staggered transverse extension lines 4 can form contact, abutment, and support at different positions, preventing the wet fabric from collapsing entirely and allowing it to continuously adhere to the human skin. A certain amount of air circulation space can still be maintained between the hollow area of ​​the mesh and adjacent transverse extension lines 4.

[0091] In terms of specific organization, the transverse extension lines 4 can extend along the fabric width and be arranged at intervals along the warp direction. Furthermore, they can be set at equal intervals to maintain a relatively uniform distribution of the transverse structure within the fabric. A single transverse extension line 4 can span 2 to 4 loops in the warp direction to balance the transverse extension distance and yarn stability. The transverse extension lines 4 can be formed by a variable warp pile structure 1, allowing the yarn to achieve the required transverse span through transverse needle crossing movement. This creates a continuous transverse yarn transfer path while also limiting the end positions of the transverse extension lines 4 by utilizing the loop positions on both sides.

[0092] Meanwhile, the warp-knitted mesh fabric may include an inner layer on the skin-contact side and an outer layer on the inner layer away from the skin-contact side. Lateral extension lines 4 are formed in the inner layer, and the outer layer includes a warp-knitted loop structure 3 that constitutes at least part of the mesh boundary. The inner layer may be woven from a first inner layer Jacquard comb and a second inner layer Jacquard comb, and the outer layer may be woven from a first outer layer Jacquard comb and a second outer layer Jacquard comb. The inner and outer layer yarns interlock during the loop-forming process, thus forming an integrated knitted structure. This structure does not involve subsequently combining two independent fabric layers; rather, the inner and outer layers and their interconnections are formed simultaneously during the warp knitting process, maintaining a relatively stable positional correspondence between the inner layer's lateral extension lines 4 and the outer layer's mesh structure.

[0093] Based on the above principles, the beneficial effects of this application are as follows: by forming at least part of the boundary of the mesh with the warp loop weave 3 and connecting the two ends of the transverse extension line 4 to the warp loop weave 3 on both sides respectively, a stable connection between the transverse yarn and the warp loop weave can be established in the mesh area. When the mesh size is increased, the transverse extension line 4 still maintains the state of being limited by the loop weave at both ends, thereby reducing the occurrence of isolated and free long floats due to the increase of the transverse span, improving the structural stability of the mesh area, and reducing the possibility of yarn displacement, curling and snagging during wearing, stretching and friction.

[0094] By aligning adjacent transverse extension lines 4 with the hollow areas of the mesh and the loop positions of the warp knit 3, and by staggering or interlacing them along the warp direction, continuous, overlapping planar yarn layers on the skin-contact side can be avoided. This allows different transverse extension lines 4 to form dispersed contact and support positions in space. Especially in a wet state, the transverse extension lines 4, after absorbing moisture and swelling, can abut against each other at different positions and share local pressure, allowing the wet fabric surface to maintain a certain degree of suspension and reducing the sticky feeling caused by large areas of fabric adhering to the skin.

[0095] The transverse extension lines 4 extend continuously along the fabric width, providing a lateral pathway for sweat to spread. When sweat comes into contact with the skin, it disperses along the capillary paths of the transverse extension lines 4 and adjacent yarns, reducing moisture concentration in localized areas. As the moisture diffusion range increases, the effective evaporation area also increases. Simultaneously, the air gaps between the staggered transverse extension lines 4 and in the hollow areas of the mesh provide channels for airflow, allowing lateral moisture diffusion and air convection to work together to improve wearing comfort in hot and humid conditions.

[0096] Furthermore, by limiting the transverse extension line 4 to the span of 2 to 4 loops in the warp, a balance can be achieved between transverse extension capability and fabric stability. This avoids the limited transverse extension range when the span is too small, while reducing the risk of pilling and snagging in long yarn segments when the span is too large. Through the integrated loop-and-loop structure of the inner and outer layers, the transverse extension structure on the skin-contact side and the outer mesh structure can directly form a stable spatial correspondence during the weaving process, reducing interlayer slippage and misalignment that may occur in the post-composite structure. This allows the mesh breathability, transverse extension, structure stability, and wet support properties to be synergistically achieved in the same warp-knitted structure system.
