Description

Technical Field

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

[0002] Warp-knitted fabric refers to fabric woven using a warp knitting machine. It is a type of knitted fabric that is left over from warp knitting. Compared to woven fabric, knitted fabric has better extensibility and is suitable for making some close-fitting garments. Close-fitting garments generally require good breathability, especially some garments designed for hot and breathable conditions. However, fabrics with good breathability are often relatively thin, and when stretched, thin fabrics are prone to excessive deformation. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a warp-knitted fabric.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a warp-knitted fabric, including a base layer, the base layer including a first yarn and a second yarn, the base layer being divided into a connecting part and a breathable part in the longitudinal direction, at the connecting part, the first yarn and the second yarn are connected to each other by recurved warp loops, at the breathable part, a breathable mesh is formed between the first yarn and the second yarn, and the area of ​​the connecting part is smaller than the area of ​​the breathable part.

[0005] The present invention is further configured such that: the padding number of the first yarn is 2-4 / 4-4 / 4-5 / 3-1 / 1-1 / 1-0 / / one thread and two empty spaces, and the padding number of the second yarn is 2-3 / 2-1 / 0-2 / 2-3 / / two thread and one empty space.

[0006] The present invention is further configured such that: the base layer also includes a third yarn, the third yarn forms a braided structure, and the tensile strength of the third yarn is greater than that of the first yarn and the second yarn.

[0007] The present invention is further configured such that the padding yarn of the third yarn is 4-3 / / one thread through two empty spaces.

[0008] The present invention is further configured such that the stretchability of the first yarn and the stretchability of the second yarn are both greater than that of the third yarn.

[0009] The present invention is further configured such that both the first yarn and the second yarn are made of twisted polyester fibers.

[0010] In summary, this utility model has the following beneficial effects: by increasing the area of ​​the breathable part, the breathability of the fabric is ensured; a breathable mesh is formed between the first yarn and the second yarn, ensuring the breathability of the breathable part; the first yarn and the second yarn still share the tensile force with each other in the longitudinal direction, avoiding excessive deformation of the fabric during stretching; the polyester fiber has good extensibility, and the warp structure formed by the first yarn and the second yarn ensures the extensibility of the fabric. Attached Figure Description

[0011] Figure 1 This is a diagram showing the movement of the first yarn in this invention.

[0012] Figure 2 This is a diagram showing the movement of the second yarn in this invention.

[0013] Figure 3 This is a diagram showing the movement of the third yarn in this invention. Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] Example: A warp-knitted fabric, such as Figure 1 As shown, the system includes a base layer, which comprises a first yarn and a second yarn. The base layer is longitudinally divided into a connecting section and a breathable section. At the connecting section, the first yarn and the second yarn are connected to each other by a recurved loop. At the breathable section, a breathable mesh is formed between the first yarn and the second yarn. The area of ​​the connecting section is smaller than the area of ​​the breathable section. The padding yarn number of the first yarn is 2-4 / 4-4 / 4-5 / 3-1 / 1-1 / 1-0 / / one thread and two gaps, and the padding yarn number of the second yarn is 2-3 / 2-1 / 0-2 / 2-3 / / two threads and one gap.

[0016] Specifically, the first yarn forms alternating warp and quilted weaves in the longitudinal direction, while the second yarn forms alternating warp and chain weaves in the longitudinal direction. A minimum weave cycle of the first yarn spans six stitches in the longitudinal direction, and a minimum weave cycle of the second yarn spans four stitches in the longitudinal direction. That is, there are eleven stitches between the two connecting parts, making the area of ​​the breathable part larger than the area of ​​the connecting part. By increasing the area of ​​the breathable part, the breathability of the fabric is ensured. Between the two connecting parts, the connection strength between the first yarn and the second yarn is relatively low, and a breathable mesh is formed between the first yarn and the second yarn, ensuring the breathability of the breathable part. At the same time, although there are fewer connection points between the first yarn and the second yarn in the breathable part, the first yarn and the second yarn still share the tensile force in the longitudinal direction, avoiding excessive deformation of the fabric when it is stretched.

[0017] The base layer also includes a third yarn, which forms a braided structure. The tensile strength of the third yarn is greater than that of the first and second yarns. The padding yarn of the third yarn is 4-3 / / one thread and two holes. The extensibility of the first and second yarns is greater than that of the third yarn. Both the first and second yarns are made of twisted polyester fibers.

[0018] Specifically, the third yarn forms a short chain structure in the longitudinal direction. There are two stitch lengths between the chain structure and the braided structure, that is, between adjacent third yarns. This ensures the fabric's durability. The third yarn is made of three strands of nylon fiber twisted together. Nylon fiber has good strength when stretched, ensuring the fabric's service life. The first and second yarns are both made of three strands of polyester fiber twisted together. Polyester fiber has good extensibility. Together with the warp structure formed by the first and second yarns, it ensures the fabric's extensibility.

[0019] 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.
