Description

Technical Field

[0001] The invention discloses a fabric with a three-layer mesh surface and bottom layer with a perforated structure and a manufacturing method thereof, belonging to the field of textile fabrics. Background Art

[0002] With the continuous development of the sports and leisure shoe market, consumers have put forward higher requirements for the breathability, comfort and aesthetics of shoes. Although traditional upper materials such as leather and synthetic fibers can provide certain breathability, they are often not breathable due to unreasonable design of air holes or limitations of the materials themselves, and lack sufficient support and durability. Woven materials stand out in upper design due to their light weight, high strength and good breathability. Woven uppers can not only provide excellent breathability, but also achieve different patterns and textures through different weaving techniques. However, how to further improve the breathability while maintaining the stability of the upper structure is an important issue facing current footwear design. Summary of the invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a three-layer mesh bottom layer perforated structure fabric and a manufacturing method thereof, so as to solve the problem that the prior art cannot further improve the air permeability while maintaining the stability of the upper structure.

[0004] In order to achieve the above object, the present invention is implemented by the following technical scheme: a fabric with a three-layer mesh bottom layer and a perforated structure and a manufacturing method thereof, which comprises: A surface layer, wherein the surface layer is a single solid layer formed by interweaving transparent yarns of different elasticities; The middle layer is a shuttle monofilament interwoven up and down at the same time, and is used to connect the surface layer above the middle layer; A bottom layer, the bottom layer is located below the middle layer, and the bottom layer is a single solid layer formed by interweaving different polyester yarns and monofilaments; The porous structure is located in the upper middle of the bottom layer. The porous structure is a warp yarn structure in which colored yarn and transparent yarn are staggered and interwoven, so that the material is stretched to form arbitrary pores, which is used to increase air permeability while enriching the layers.

[0005] Furthermore, the weft yarn of at least one of the surface layer or the bottom layer is made of transparent elastic yarn, and the transparent elastic yarn is specifically one of TPU, TPE, TPEE, PET, polyester, and nylon.

[0006] Furthermore, the weft yarn of the surface layer is made of transparent elastic yarn, the monofilament used in the middle layer is transparent monofilament, and the weft yarn of the bottom layer is made of polyester high-elastic yarn and ordinary polyester yarn distributed alternately.

[0007] Furthermore, the middle layer uses a single yarn to be bent in a triangular shape or an arch shape along the warp direction or the weft direction to connect the surface layer and the bottom layer, so that the upper and lower layers of the middle layer are not easy to delaminate.

[0008] Furthermore, the hole-like structure is realized by adopting a staggered interlaced warp yarn structure, and the staggered warp yarn structure can be changed along the length or width direction of the fabric to form different hole-like patterns.

[0009] Furthermore, the fabric contains a shuttle of colored polyester yarn, which can pass through the surface layer and be reflected in the middle layer and the bottom layer, while being hidden in the bottom layer, so as to enrich the layering of the fabric and form a jacquard effect between the surface layer and the bottom layer.

[0010] Furthermore, after the monofilaments of the middle layer are subjected to high-temperature shaping treatment, the monofilaments stand up and support the upper and lower solid layers, so that the surface layer can see through the porous structure of the bottom layer.

[0011] Furthermore, side reinforcement sheets are symmetrically arranged on the surface layer to provide additional support and wear resistance.

[0012] A method for manufacturing a three-layer mesh bottom layer openwork structure fabric comprises the following steps: S1. According to the designed fabric, determine the weaving process, improve the relevant parameters, use the weaving software to make an EP format file and input it into the shuttle loom; S2. Prepare yarn according to the fabric. The warp yarn head of the woven warp is a pre-installed transparent monofilament. The weft yarn is composed of 8 weft accumulators. Place each specification of yarn in the weft accumulator in order according to the requirements of the pattern. S3, start the shuttle loom to weave an initial product with a total width of 180CM, the weaving method is weaving from bottom to top, and the machine automatically interweaves different weft yarns with the warp yarns in sequence; S4, the initial product obtained in step S3 is subjected to high temperature shaping, wherein the shaping temperature is approximately 150 to 180 degrees, so that the entire fabric is smoother; S5. After the film draft is designed, the fabric is cut into pieces and the upper is processed by laser.

[0013] The beneficial effects of the present invention are: When the user uses a fabric with a three-layer mesh bottom layer and a perforated structure, the surface layer of the fabric is closely connected by transparent elastic monofilament warp and weft interweaving, the bottom layer uses ordinary polyester elastic yarn and ordinary polyester yarn interwoven with each other, and the middle layer is one or more shuttle monofilaments interwoven up and down at the same time, so that the upper and lower structures will not delaminate. In the combination of the above three structures, there is also a shuttle yarn that can pass through the surface layer and can be reflected between the middle layer and the bottom layer, and can be hidden in the bottom layer, so that the entire fabric has a rich sense of layering, and a hole structure is also provided in the middle and upper part of the bottom layer. The material is stretched to form an arbitrary hole structure by adopting a staggered interweaving warp yarn structure of colored yarn and transparent monofilament yarn, and the fabric is finally set at high temperature to make the monofilaments of the middle layer stand up and stretch the upper and lower solid layers. The fabric realizes the hole structure of the surface layer that can see through the bottom layer through the layered structure, and the hole structure of the bottom layer can further improve the breathability of the shoe upper.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides a three-layer mesh bottom layer perforated structure fabric and a technical solution for manufacturing the same, which includes: A surface layer 1, wherein the surface layer 1 is a single solid layer formed by interweaving transparent yarns of different elasticities; The middle layer 2 is a shuttle monofilament interwoven up and down, and is used to connect the surface layer 1 above the middle layer 2; A bottom layer 3, the bottom layer 3 is located below the middle layer 2, and the bottom layer 3 is a single solid layer formed by interweaving different polyester yarns and monofilaments; The porous structure 4 is located in the upper middle of the bottom layer. The porous structure 4 is a warp yarn structure in which colored yarn and transparent yarn are interlaced in a staggered manner, so that the material is stretched to form any pore shape, which is used to increase air permeability while enriching the layers.

[0019] In order to increase air permeability and light transmittance, the weft yarn of at least one of the surface layer 1 or the bottom layer 3 is made of transparent elastic yarn, and the transparent elastic yarn is specifically one of TPU, TPE, TPEE, PET, polyester, and nylon.

[0020] In order to improve the comfort of the user, the weft yarn of the surface layer 1 is made of transparent elastic yarn, the monofilament used in the middle layer 2 is transparent monofilament, and the weft yarn of the bottom layer 3 is made of polyester high-elastic yarn and ordinary polyester yarn distributed alternately.

[0021] In order to improve the strength of the fabric, the middle layer 2 uses a single yarn to be bent in a triangular or arched shape along the warp direction or the weft direction to connect the surface layer 1 and the bottom layer 3, so that the upper and lower layers of the middle layer are not easy to delaminate.

[0022] In order to increase the air permeability and structural flexibility of the fabric, the pore structure 4 is implemented by a staggered interlaced warp yarn structure, and the staggered warp yarn structure can be changed along the length or width direction of the fabric to form different pore patterns.

[0023] In order to form a jacquard effect and increase the visual effect, the fabric contains a shuttle of colored polyester yarn, which can pass through the surface layer 1 and be reflected in the middle layer 2 and the bottom layer 3, while being hidden in the bottom layer 3 to enrich the layering of the fabric and form a jacquard effect between the surface layer 1 and the bottom layer 3.

[0024] In order to enhance the stability of the structure, after the monofilaments of the middle layer 2 are subjected to high-temperature shaping treatment, the monofilaments stand up and support the upper and lower solid layers, so that the surface layer 1 can see through the porous structure 4 of the bottom layer 3.

[0025] In order to increase the support and wear resistance of the fabric, side reinforcement sheets 101 are symmetrically provided on the surface layer 1 to provide additional support and wear resistance.

[0026] Figure 5 Schematic diagram of the steps of the manufacturing method of a three-layer mesh bottom layer openwork structure fabric of the present invention, referring to Figure 5 As shown, in order to achieve precise manufacturing and precise processing, the present invention also provides a method for manufacturing a three-layer mesh bottom layer openwork structure fabric, comprising the following steps: S1. According to the designed fabric, determine the weaving process, improve the relevant parameters, use the weaving software to make an EP format file and input it into the shuttle loom; S2. Prepare yarn according to the fabric. The warp yarn head of the woven warp is a pre-installed transparent monofilament. The weft yarn is composed of 8 weft accumulators. Place each specification of yarn in the weft accumulator in order according to the requirements of the pattern. S3, start the shuttle loom to weave an initial product with a total width of 180CM, the weaving method is weaving from bottom to top, and the machine automatically interweaves different weft yarns with the warp yarns in sequence; S4, the initial product obtained in step S3 is subjected to high temperature shaping, wherein the shaping temperature is approximately 150 to 180 degrees, so that the entire fabric is smoother; S5. After the film draft is designed, the fabric is cut into pieces and the upper is processed by laser.

[0027] [Beneficial description of a fabric with a three-layer mesh bottom layer with openwork structure according to the present invention] When the user uses a fabric with a three-layer mesh bottom layer with a perforated structure, the surface layer 1 of the fabric is closely connected by transparent elastic monofilament warp and weft interweaving, the bottom layer 3 uses ordinary polyester elastic yarn and ordinary polyester yarn interwoven with each other, and the middle layer 2 is one or more shuttle monofilaments interwoven up and down at the same time, so that the upper and lower structures will not delaminate. In the combination of the above three structures, there is also a shuttle yarn that can pass through the surface layer 1 and can be reflected between the middle layer 2 and the bottom layer 3, and can be hidden in the bottom layer 3, so that the entire fabric has a rich sense of layering, wherein a porous structure 4 is also provided in the middle and upper part of the bottom layer 3. The material is stretched to form an arbitrary porous structure by adopting a staggered interweaving warp yarn structure of colored yarn and transparent monofilament yarn, and the fabric is finally set at high temperature to make the monofilament of the middle layer 2 stand up and stretch the upper and lower solid layers. The fabric realizes that the surface layer 1 can see through the porous structure 4 of the bottom layer 3 through a layered structure, and the porous structure 4 of the bottom layer 3 can further enhance the breathability and layering of the shoe upper.

[0028] The monofilament structure of the middle layer 2 of the present application mainly includes two connection methods. The first is that the monofilament structure forms a triangular support structure in the vertical direction, the vertex of which is connected to the surface layer 1, and the bottom edge is connected to the bottom layer 3. This triangular connection method significantly improves the stability and deformation resistance of the entire fabric structure, and can effectively disperse the stress on the fabric, reducing the risk of damage due to local force. In addition, the gap formed by the triangular connection can increase air flow, thereby improving the air permeability of the fabric; the second is that the monofilament structure forms an arch-shaped connection in the vertical direction, the highest point of the top is connected to the surface layer 1, and the two ends are connected to the bottom layer 3. This arch-shaped connection method has good elasticity and recovery, and can quickly return to its original state after being subjected to external force, making the fabric more durable, and the arch shape creates more space between the surface layer 1 and the bottom layer 3, which helps to increase the air permeability and comfort of the fabric. Therefore, the connection method of the monofilament structure of the middle layer 2 can be selected according to specific design requirements and application scenarios.

[0029] The pore structure 4 on the bottom layer 3 of the present application can be displaced and varied, and the arrangement of the pore structure 4 can be regular or irregular. The regular pore structure can provide uniform air permeability, which is helpful for air circulation and moisture removal, and also helps to maintain the consistency of the fabric structure, so that the performance of the fabric in different areas is more balanced. In addition, the regular arrangement is also easy to control and replicate during the production process, which helps to improve production efficiency and product quality; the irregular arrangement can provide different air permeability and moisture permeability according to the division of regional functions, and can also better adapt to the complex shape and structure of the fabric, especially in applications that need to fit the curves of the human body.
