The outer layer is formed with a plurality of perforations. The inner layer has a plurality of antibacterial parts one and a plurality of antibacterial parts two on the side facing the outer layer. The plurality of antibacterial parts one and the plurality of antibacterial parts two are arranged at intervals. A flow space is formed between the inner layer and the outer layer.

[0009] The present invention is further configured such that: the inner layer is woven from bamboo fiber yarn and photocatalytic antibacterial yarn in a single-sided discontinuous pleat structure, and the inner layer facing the outer layer is uneven.

[0010] This utility model is further configured such that: the inner layer is arranged in an eight-way loop, with the first, second, third, and fourth ways being floats, loops, and loops in sequence; the fifth, sixth, seventh, and eighth ways being loops, loops, and loops in sequence; the ninth, tenth, eleventh, and twelfth ways being loops, loops, and floats in sequence; and the thirteenth, fourteenth, fifteenth, and sixteenth ways being loops, loops, and loops in sequence. The first, second, third, fourth, ninth, tenth, eleventh, and twelfth ways are all made of bamboo fiber yarn, while the fifth, sixth, seventh, eighth, thirteenth, fourteenth, fifteenth, and sixteenth ways are all made of photocatalytic antibacterial yarn.

[0011] The present invention is further configured such that: the outer layer is woven from wear-resistant yarn in a perforated structure, the perforated structure is a six-way loop, the first, fourth, fifth and eighth ways are looping, gathering looping, looping and gathering looping in sequence, the second and seventh ways are gathering looping, looping, gathering looping and looping, and the third and sixth ways are gathering looping, looping, floating thread and looping.

[0012] The present invention is further configured such that the wear-resistant yarn is made of polyester irregularly shaped fibers with a triangular cross-section by twisting.

[0013] The present invention is further configured such that the connecting part is made of hot melt adhesive material.

[0014] In summary, this utility model has the following beneficial effects:

[0015] Light shines through the perforations onto the inner layer, utilizing the photocatalytic properties of the nano-silica on the photocatalytic antibacterial yarn to capture surrounding bacteria and reduce their activity. At the same time, the antibacterial function of the bamboo fiber yarn itself is used to enhance the antibacterial effect of the knitted fabric and improve hygiene and safety.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figure 1 As shown, this application provides a composite antibacterial knitted fabric, including an inner layer 1 and an outer layer 2. When the inner layer 1 and the outer layer 2 are connected, a number of hot melt adhesives are extruded on the surface of the inner layer 1 and arranged in an array. Then, the outer layer 2 is laid on the inner layer 1. The inner layer 1 and the outer layer 2 are bonded together by heat and pressure. The hot melt adhesive is cured into a connecting part 3. The connecting part 3 provides support, so that a flow space is formed between the inner layer 1 and the outer layer 2.

[0023] like Figure 2 As shown, the outer layer 2 is woven from abrasion-resistant yarn in a perforated structure. The perforated structure is a six-way loop. The first, fourth, fifth, and eighth routes are loop-forming, loop-forming, loop-forming, and loop-forming respectively. The second and seventh routes are loop-forming, loop-forming, loop-forming, and loop-forming. The third and sixth routes are loop-forming, loop-forming, float yarn, and loop-forming. This results in the outer layer 2 having several perforations 4, allowing air to pass through the perforations 4 and increasing the overall breathability of the knitted fabric. The abrasion-resistant yarn is made of twisted polyester shaped fibers with a triangular cross-section. Polyester material has the characteristics of abrasion resistance and high strength, which improves the durability of the knitted fabric.

[0024] like Figure 3As shown, the inner layer 1 is woven from bamboo fiber yarn and photocatalytic antibacterial yarn in a single-sided discontinuous pleat structure. The photocatalytic antibacterial yarn is made of polypropylene yarn with nano-silica attached to the surface and twisted. The inner layer 1 is in an eight-way loop. The first, second, third and fourth ways are floats, loops and loops respectively; the fifth, sixth, seventh and eighth ways are loops, loops and loops respectively; the ninth, tenth, eleventh and twelfth ways are loops, loops and floats respectively; the thirteenth, fourteenth, fifteenth and sixteenth ways are loops, loops and loops respectively. The first, second, third, fourth, ninth, tenth, eleventh and twelfth ways are all made of bamboo fiber yarn, and the fifth, sixth, seventh, eighth, thirteenth, fourteenth, fifteenth and sixteenth ways are all made of photocatalytic antibacterial yarn. This weaving method makes the inner layer 1 uneven towards the outer layer 2.

[0025] Light shines through the perforations 4 onto the inner layer 1. Utilizing the photocatalytic properties of the nano-silica on the photocatalytic antibacterial yarn, it captures surrounding bacteria and reduces their activity. The flow space enhances this effect. At the same time, the antibacterial function of the bamboo fiber yarn itself is utilized to enhance the antibacterial effect of the knitted fabric and improve hygiene and safety. Furthermore, the uneven surface of the inner layer 1 and the triangular structure of the polyester irregular fibers increase the complexity of the surface, thereby increasing the range of light refraction and reflection and improving the photocatalytic antibacterial effect.

[0026] 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.
