[0002] With the advancement of science and technology and the development of society, my country's textile industry has developed rapidly, and along with it has come the rapid development of fabrics, with more and more different types of fabrics emerging.

[0003] Knitted fabric is a fabric formed by bending yarn into loops and interlacing them with knitting needles. It is divided into warp knitted fabric and weft knitted fabric. It is one of the most widely used fabrics. Knitted fabric has the characteristics of soft texture, breathability and coolness, and has great extensibility and elasticity. Therefore, it is often made into underwear, tights and sportswear, etc., and is welcomed and loved by consumers.

[0004] At present, in order to improve the breathability of existing knitted fabrics, a number of ventilation holes are opened on them. However, the structural strength of the ventilation holes is relatively low. When the knitted fabric is pulled by external force, the ventilation holes will be stretched, resulting in deformation. Utility Model Content

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a composite knitted fabric, including a base layer and a surface layer, the base layer is provided with a plurality of first air holes, the surface layer is provided with a plurality of second air holes connected with the first air holes, the edges of the first air holes and the second air holes are circumferentially provided with a plurality of open grooves, a plurality of elastic gaskets are arranged between the base layer and the surface layer, the elastic gaskets are bonded between the first air holes and the second air holes, and a through hole connected with the first air holes and the second air holes is provided at the center of the elastic gasket.

[0007] As a further configuration of the utility model, the elastic gasket is formed by weft knitting a plurality of elastic yarns, the elastic yarn comprises a core and a covering yarn spirally wound on the outside of the core, and the core is formed by twisting a plurality of spandex fibers.

[0008] As a further configuration of the utility model, the covered yarn is formed by spirally twisting a first winding and a second winding, the first winding is formed by twisting a plurality of Kevlar fibers, and the second winding is formed by twisting a plurality of hemp fibers.

[0009] As a further configuration of the utility model, the base layer is formed by weft knitting a plurality of first textile yarns, and the first textile yarns are formed by twisting a plurality of modal fibers.

[0010] As a further configuration of the utility model, the surface layer is formed by weft knitting a plurality of second textile yarns, and the second textile yarns are formed by twisting a plurality of viscose fibers.

[0011] As a further configuration of the utility model, the base layer and the surface layer are bonded together by hot melt adhesive.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides an opening groove so that the first air hole and the second air hole can actively expand and deform toward the outer edge, and in the deformation process, can stretch the elastic gasket, so that it extends and undergoes elastic deformation to alleviate the impact, and avoids tearing due to excessive external force, and after the external force disappears, the elastic gasket can automatically rebound, thereby driving the first air hole and the second air hole to return to their original shape. Since the first air hole and the second air hole can actively deform when subjected to force and can automatically recover, they can avoid being completely stretched and deformed by external force, so that the knitted fabric has better shape retention.
