Description

Technical Field

[0001] This utility model relates to the textile field, and more specifically, to a knitted breathable fabric. Background Technology

[0002] Knitted fabric is a textile formed by interlocking and connecting yarns. Because it has better stretch and softness than woven fabric, it is often used in the production of clothing.

[0003] The light-blocking property of a fabric refers to its ability to reduce the passage of light. In general light-blocking fabrics, a higher weaving density is often chosen to improve the light-blocking property. However, the increase in weaving density will lead to a decrease in the overall breathability of the fabric, making it difficult for the fabric to have both light-blocking and breathability. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a knitted breathable fabric.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a knitted breathable fabric, comprising a first surface layer and a second surface layer, the first surface layer and the second surface layer being sewn together, both the first surface layer and the second surface layer being provided with a plurality of mesh structures, the first surface layer having a plurality of longitudinal convex strips arranged in a linear array, the second surface layer having a plurality of transverse convex strips arranged in a linear array, the longitudinal convex strips being perpendicular to the transverse convex strips, and the transverse convex strips abutting against the longitudinal convex strips.

[0006] The present invention is further configured such that: both the first surface layer and the second surface layer are weft knitted structures, the first surface layer has warp padding yarn at the longitudinal protrusions, and the second surface layer has weft padding yarn at the transverse protrusions.

[0007] The present invention is further configured such that the first surface layer is located outside the second surface layer.

[0008] The present invention is further configured such that: both the first surface layer and the second surface layer are woven from base yarn into a looped mesh structure.

[0009] The present invention is further configured such that the diameter of both the warp padding yarn and the weft padding yarn is greater than the diameter of the base yarn.

[0010] The present invention is further configured such that the twist direction of the weft padding yarn is opposite to that of the base yarn.

[0011] In summary, this utility model has the following beneficial effects: the mutually opposing longitudinal and transverse convex ridges ensure that there is a flow channel between the first and second surface layers, ensuring that air can pass between the first and second surface layers, giving the knitted fabric good breathability; the first surface layer first reduces the transmission of some light, and then the second surface layer blocks the remaining light, reducing the overall light transmitted through the knitted fabric and ensuring the light-blocking property of the knitted fabric; the cotton fiber bundles have good softness and moisture absorption, making the knitted fabric soft and dry.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] Example: A knitted breathable fabric, such as Figure 1 , Figure 2 As shown, it includes a first surface layer and a second surface layer, which are stitched together. Both the first and second surface layers have several mesh structures. The first surface layer has several longitudinal convex strips arranged in a linear array, and the second surface layer has several transverse convex strips arranged in a linear array. The longitudinal convex strips are perpendicular to the transverse convex strips, and the transverse convex strips abut against the longitudinal convex strips.

[0017] Specifically, the mesh structure on the first and second layers ensures gas exchange between the two sides of the first and second layers. The opposing longitudinal and transverse ridges ensure that there are interconnected flow channels between the first and second layers, allowing air to pass between them, thus giving the knitted fabric good breathability. The first layer first reduces some of the light transmission, and then the second layer blocks the remaining light, reducing the overall light transmission through the knitted fabric and ensuring its light-blocking properties.

[0018] like Figure 1 , Figure 2 As shown, both the first and second face layers are weft-knitted structures. The first face layer has warp padding yarn 1 at the longitudinal convex stripe, and the second face layer has weft padding yarn 2 at the transverse convex stripe. The first face layer is located outside the second face layer. Both the first and second face layers are woven into a tucked mesh structure by base yarn 3. The diameter of the warp padding yarn 1 and the diameter of the weft padding yarn 2 are both larger than the diameter of the base yarn 3. The twist direction of the weft padding yarn 2 is opposite to that of the base yarn 3.

[0019] Specifically, both the first and second surface layers are weft-knitted using a circular knitting machine. The first surface layer forms longitudinal ridges by intermittently padding warp padding yarns 1 in the weft direction, while the second surface layer forms transverse ridges by intermittently padding weft padding yarns 2 in the warp direction. The connection stability between the warp padding yarns 1 and the first surface layer is higher. Therefore, placing the first surface layer outside the second surface layer allows it to contact the outside environment, improving the structural stability of the knitted fabric surface. Furthermore, the opposite twist directions between the base yarn 3 and the weft padding yarns 2 constituting the second surface layer enhance the stability of the weft padding yarns 2 in the second surface layer. To ensure stability, the mesh structure formed by the loops on the first layer is distributed between adjacent warp padding yarns 1, and the mesh structure formed by the loops on the second layer is distributed between adjacent weft padding yarns 2. This avoids the warp padding yarns 1 or weft padding yarns 2 affecting breathability. At the same time, by increasing the diameter of the warp padding yarns 1 and the diameter of the weft padding yarns 2, the airflow between the first and second layers is ensured. The base yarn 3, warp padding yarns 1 and weft padding yarns 2 are all made of twisted cotton fiber bundles. Cotton fiber bundles have good softness and moisture absorption, making the knitted fabric soft and dry.

[0020] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
