[0015] The utility model is further explained below in combination with the drawings and specific embodiment.

[0016] In combination Figs. 1-2 Detailed description is made to this embodiment, a kind of antibacterial ventilative warp knitting fabric, comprising: the wet conduction antibacterial layer 1 and wear -resisting layer 2 of complex, the wet conduction antibacterial layer 1 and wear -resisting layer 2 are compounded by dot hot melt type PU glue 3;The wet conduction antibacterial layer 1 is warp knitting mesh fabric;The wet conduction antibacterial layer 1 is woven by GB1, GB2 two guide bars threading yarn;The GB1 is inserted into wet conduction yarn, and the GB2 is inserted into antibacterial yarn;The wear -resisting layer 2 is warp plain fabric;The wear -resisting layer 2 is woven by wear -resisting yarn.

[0017] The forming principle of warp knitting mesh fabric is that adjacent loops lose contact in the longitudinal direction, thereby forming a certain shape of mesh hole on the warp knitting fabric. The large number of evenly distributed holes on the warp knitting mesh fabric provide a direct channel for air flow, and air can freely exchange inside and outside through these holes, so that the fabric has good air permeability.

[0018] The loops formed by the same warp yarn in warp plain weave are alternately arranged in two adjacent loop longitudinal rows. This loop structure allows more gaps and channels for air flow between yarns, and air can flow smoothly in the fabric. Warp plain fabric has a flat surface, similar to plain weave in woven fabric, but it also has certain elasticity and extensibility. This relatively light, flat and elastic fabric form does not hinder air flow, which is conducive to the entry and exit of air, thereby having good air permeability.

[0019] Specifically, the point-shaped hot melt PU glue 3 is arranged in an array, and gaps exist between adjacent point-shaped hot melt PU glues 3, which not only ensures the air permeability of the fabric, but also ensures the elasticity of the fabric.

[0020] Further, the number of the lapping stitches and the lapping mode of GB1 and GB2 are as follows:

[0021] GB1: 1-0 / 1-2 / 1-0 / 2-3 / 2-1 / 2-3 / / , one lapping and one empty;

[0022] GB2: 3-4 / 3-2 / 3-4 / 2-1 / 2-3 / 2-1 / / , one lapping and one empty.

[0023] Specifically, the warp-knitted mesh fabric is a changed warp plain mesh organization, and the mesh formed by the combination of the warp plain and the changed warp plain forms a hole at the warp plain, and the size of the hole can be changed by increasing or reducing the number of the courses of the warp plain section by using the changed warp plain to close the hole.

[0024] Further, the moisture-conducting yarn is a U-shaped cross-section polyester filament. The U-shaped cross-section polyester filament is a fiber produced by using a U-shaped spinneret, and belongs to a differentiated fiber. The U-shaped cross-section polyester filament has a cross-section similar to the English letter U. Because the fiber groove is deep, some fibers are even flattened, so that the groove disappears. The fiber structure forms a fabric with more fine grooves, thereby forming more capillary channels, which is very beneficial to the conduction of water. In addition, the U-shaped cross-section polyester filament has a large specific surface area, and the fabric formed by the U-shaped cross-section polyester filament has good moisture-conducting and quick-drying properties.

[0025] Further, the antibacterial yarn is a far-infrared antibacterial nanofiber blended yarn. The far-infrared antibacterial nanofiber blended yarn is obtained by adding silicon dioxide and zinc oxide nanoparticles to a spinning solution, depositing silicon dioxide / zinc oxide / polyurethane nanofibers on a uniformly transported cotton web by electrospinning, and then being made by a traditional spinning process. The synergistic effect of silicon dioxide and zinc oxide can effectively enhance the far-infrared emission function of the fabric. The emissivity increases with the increase of the mass fraction of the nanoparticles. When the mass fraction is 6%, the yarn has good morphology and mechanical properties, and also has high far-infrared emissivity and excellent antibacterial performance. The far-infrared emissivity is 0.896, and the inhibition rate of Escherichia coli and Staphylococcus aureus is 99.99%.

[0026] Further, the wear-resistant yarn is a polyamide filament. The polyamide has a large number of amide bonds in the molecular chain, and the molecular chains can be connected with each other through hydrogen bonds and other forces to form a relatively compact structure. The compact molecular structure makes the polyamide fiber have high strength and toughness, can resist the damage of external force, and thus exhibits good wear resistance. The flexibility of the polyamide molecular chain is also good. When subjected to external forces such as friction, the molecular chain can relatively flexibly adjust and deform, rather than easily break, which also helps to improve the wear resistance.

[0027] The above describes preferred embodiments of the present application in detail. It should be understood that those skilled in the art can make many modifications and changes without creative labor according to the concept of the present application. Therefore, any technical solution obtained by logical analysis, reasoning or limited experiment on the basis of the existing technology according to the concept of the present application shall be within the protection scope defined by the claims.
