Description

Technical Field

[0001] This utility model relates to the field of mesh fabric production technology, and in particular to a mesh fabric with a one-way breathable structure. Background Technology

[0002] In mesh fabrics with a one-way breathable structure, the edge binding structure, although located at the edge, is a key element in ensuring the multi-layer collaborative function of the mesh fabric and improving its overall durability. Traditional multi-layer mesh fabrics often use single-layer overlocking or simple folding and sewing techniques for their edges, without designing special edging for the characteristics of multi-layer structures. Some mesh fabrics are simply sewn together with ordinary needle and thread to connect the different layers. Due to the significant differences in fiber density and extensibility among the mesh layers, moisture-wicking layers, and breathable layers, the fibers at the edges of each layer are prone to loosening and falling off due to uneven stress during use, forming "rough edges." This not only affects the appearance but also causes the layers to gradually separate, compromising the one-way moisture-wicking and breathable functions of the mesh fabric. Therefore, these problems need to be addressed. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 4This utility model discloses a mesh fabric with a one-way breathable structure, comprising a mesh layer 3, with a waterproof and breathable layer 1 glued to the top surface of the mesh layer 3 for waterproofing. The waterproof and breathable layer 1 effectively prevents external liquids from penetrating the mesh fabric while allowing moisture inside the mesh fabric to dissipate outwards. A first one-way moisture-wicking layer 4 is provided at the bottom of the mesh layer 3, which quickly absorbs moisture from one side of the mesh layer 3 and guides it through moisture-wicking grooves to conical vent holes 9. The bottom of the first one-way moisture-wicking layer 4 is provided with… One-way breathable layer 5 facilitates the rapid flow of moisture from the large-diameter end to the small-diameter end while suppressing reverse airflow, thus achieving one-way breathability. An auxiliary bonding block 6 is pressed between the one-way breathable layer 5 and the first one-way moisture-wicking layer 4. The auxiliary bonding block 6 helps to ensure connection stability and avoids large-area adhesion that blocks the breathable path. A flexible layer 10 is provided at the bottom of the one-way breathable layer 5. A second one-way moisture-wicking layer 8 is provided between the flexible layer 10 and the one-way breathable layer 5. A binding fabric 2 is sewn around the flexible layer 10 and the waterproof breathable layer 1.

[0015] In this invention, the one-way breathable layer 5 is composed of an array of multiple conical breathable holes 9. The large-diameter end of the conical breathable hole 9 abuts against the first one-way moisture-wicking layer 4, and the small-diameter end of the conical breathable hole 9 abuts against the flexible layer 10. The inner wall of the conical breathable hole 9 is coated with an oleophobic coating. Connecting holes are staggered with the conical breathable holes 9 on the one-way breathable layer 5, and connecting blocks 7 for reinforcing the strength of the mesh are inserted into the connecting holes. The conical breathable holes 9 facilitate the generation of pressure difference due to cross-sectional changes when moisture flows, accelerating the flow towards the small-diameter end and achieving efficient one-way breathability. The first one-way moisture-wicking layer 4 is made of a blend of bamboo fiber and polyester fiber. Multiple moisture-wicking grooves are formed on the surface of the first one-way moisture-wicking layer 4. The moisture-wicking grooves are radially distributed and correspond to the conical breathable holes 9 of the one-way breathable layer 5. The moisture-wicking grooves facilitate the guidance of adsorbed moisture along the groove channels. Rapid diffusion prevents localized accumulation and the formation of damp areas; the bonding block 6 consists of hot melt adhesive protrusions arranged in a circular array. A breathable gap is created between the first unidirectional moisture-wicking layer 4 and the unidirectional breathable layer 5 via the bonding block 6. The flexible layer 10 is woven from cotton and spandex fibers, with a napped surface and anti-slip dots sewn to the bottom. These dots are made of silicone and arranged in a diamond array. The flexible layer 10 provides a soft touch and moisture absorption, enhancing skin-friendliness. The binding fabric 2 is woven from high-elastic nylon yarn, with reinforcing ribs fixed to its inner side. These reinforcing ribs are made of polyester monofilament. The binding fabric 2 is stitched with double-needle overlock stitches to each layer, allowing it to adapt to the stretching and deformation of the mesh fabric and preventing edge cracking. The reinforcing ribs enhance the structural strength of the binding and improve durability.

[0016] Working Principle: In the application of this invention, the outermost layer of the mesh fabric is a waterproof and breathable layer 1 glued to the top surface of the mesh fabric layer 3. The dense structure of the waterproof and breathable layer 1 prevents liquid from seeping into the mesh fabric, avoiding internal moisture penetration and the breathable layer from becoming wetted and failing. At the same time, the microporous structure of the waterproof and breathable layer 1 allows moisture that has been discharged from the mesh fabric to dissipate outwards, preventing external water intrusion without hindering the final discharge of internal moisture. Next, the mesh fabric layer 3 serves as the supporting foundation for the waterproof and breathable layer 1. Its mesh skeleton structure provides a stable mounting carrier for the waterproof and breathable layer 1, preventing deformation and damage due to lack of support. It also ensures that internal moisture can be smoothly transferred upwards to the waterproof and breathable layer 1 through its own breathability. Then, when moisture is generated on the inside of the mesh fabric, it is first initially absorbed by the second unidirectional moisture-wicking layer 8. Through capillary action between fibers, the moisture is transferred upwards to the unidirectional breathable layer 5, and then from the unidirectional breathable layer 5 to the first unidirectional moisture-wicking layer 4. At this point, the moisture-guiding grooves on the surface of the first unidirectional moisture-guiding layer 4 play a key guiding role. The moisture-guiding grooves correspond one-to-one with the conical vent holes 9 of the unidirectional breathable layer 5, and the end of the grooves points directly to the large-diameter end of the conical vent holes 9, so that the moisture can be transported to the inlet of the conical vent holes 9 without misalignment, avoiding moisture loss due to path deviation during interlayer transmission. In addition, the bonding block 6 between the first unidirectional moisture-guiding layer 4 and the unidirectional breathable layer 5 separates the breathable gap, preventing the moisture-guiding grooves and the inlet of the conical vent holes 9 from being blocked due to direct bonding between the two layers, ensuring that the moisture can flow smoothly from the moisture-guiding grooves into the conical vent holes 9. At the same time, the connection stability between the two layers is enhanced by point fixation, preventing the moisture-guiding grooves and the conical vent holes 9 from losing their correspondence due to interlayer misalignment. Finally, after the moisture passes through the conical vent holes 9, completes the unidirectional transmission, and is finally discharged through the waterproof breathable layer 1, the flexible layer 10 of the inner layer of the mesh fabric is responsible for improving the comfort of use. At this point, the use of a mesh fabric with a unidirectional breathable structure is completed.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
