[0007] The utility model is further provided: the antibacterial layer is formed by polyester yarn knitting rib organization, and the antibacterial yarn is padded on the rib organization in the warp direction.

[0008] The utility model is further provided: the rib organization is 1+1 rib organization, and two needle pitches are separated between adjacent antibacterial yarns.

[0009] The utility model is further provided: the polyester yarn is twisted by hollow polyester filament, and the antibacterial yarn is twisted by bamboo fiber.

[0011] The utility model is further provided: the cotton layer is knitted by cotton yarn to form rib air layer organization.

[0012] In summary, this utility model has the following beneficial effects: the elastic layer has good elasticity and extensibility, so that during the stretching and deformation of the elastic layer, the wrinkled parts on the antibacterial layer and the parts of the cotton layer covering the protrusions will gradually become flat. This design ensures that even if the extensibility of the cotton layer and the antibacterial layer is relatively weak, the fabric as a whole still has good extensibility. The elastic layer also has good elastic recovery ability, which enables the elastic layer to drive the fabric to recover as a whole, thus ensuring the overall elasticity of the fabric.

The protrusions 5 are composed of several pleats 4, and the thickness of the protrusions 5 is greater than the thickness of the flat portions 6. Part of the cotton layer 1 is embedded in the flat portions 6, forming several grooves 7 on one side of the fabric. The elastic layer 2 has good elasticity and extensibility, so that during the stretching and deformation of the elastic layer 2, the pleats 4 on the antibacterial layer 3 and the cotton layer 1 cover the fabric. The portion on the protrusion 5 will gradually flatten out. This design ensures that even though the cotton layer 1 and antibacterial layer 3 have relatively weak extensibility, the fabric as a whole still has good extensibility.
