Description

Technical Field

[0001] The utility model relates to the technical field of textiles, and specifically, to a single-layer mesh fabric with a multi-layer structure. Background Art

[0002] In the existing Jacquard mesh fabric technology, usually a full machine number Jacquard comb (JB1) is adopted, which is divided into two half machine number Jacquard combs (JB1.1 and JB1.2), and is combined with a ground comb. By offsetting signals, plain weave and mesh holes are made to complete the design of the entire fabric style. In order to achieve the lightweight of the mesh fabric, usually the fabric specifications are adjusted, such as reducing the gram weight of the fabric, and combining yarns with different lusters to present the transparency of the material, so as to reflect the visual lightweight of the mesh fabric. In addition, a single-sided knitting structure is also adopted to further reduce the weight.

[0003] When using a single set of full machine number Jacquard comb (JB1), when using a lower D number yarn specification, it is easy to cause the material to curl, which is not conducive to the subsequent setting process operation. More importantly, since the Jacquard comb in the same direction can only present an oval hole shape, and although the Jacquard comb in the opposite direction can form uniform small holes in the plain weave area, it cannot achieve a dense plain weave effect, which has a significant impact on the physical properties of the fabric. Specifically, due to the limitation of the hole shape and the influence of the opposite tension, the fabric may show poor dimensional stability, low tear strength and tensile resistance. These problems not only limit the realization of the lightweight of the mesh fabric, but also make the material effect relatively single and cannot meet the market demand for high-performance and diversified mesh fabrics.

[0004] To solve these problems, the existing technology attempts to add a set of full machine number Jacquard comb (JB2), which is divided into two half machine number Jacquard combs (JB2.1 and JB2.2), and is used in combination with the original full machine number Jacquard comb (JB1). When these two sets of Jacquard combs are woven in the same direction, due to the action of the same direction tension, the material may have weft skewing. When they are woven in the opposite direction, the weft skewing problem can be effectively improved, and a dense plain weave area can be presented. However, the action of the opposite tension will cause the mesh holes to present a unified oval or circular effect, and there are strict requirements for the tension control of the machine, which makes the style performance of the mesh holes not rich and diverse enough.

[0005] In summary, although the existing Jacquard mesh fabric technology has achieved lightweight to a certain extent, there are still deficiencies in improving the physical properties of the fabric, especially in terms of dimensional stability, tear strength and tensile resistance, and it cannot fully meet the market demand for high-performance and diversified mesh fabrics. Summary of the Invention

[0006] To solve the technical problem of insufficient physical properties of Jacquard fabric in achieving lightweight in the above-mentioned existing technologies, the present utility model provides a single-layer fabric with a multi-layer structure.
