[0010] Further, the ratio of the Y-shaped cross-section yarn to the O-shaped cross-section yarn is 3:1-1:1.

[0011] Further, the hollow rate of the hollow air-permeable layer is controlled at 8%-12%.

[0012] Further, the warp yarn and weft yarn adopt plain weave.

[0013] Further, the denier of the first yarn and the second yarn is the same, being 20D-30D.

[0014] After the above structure is adopted, compared with the existing down jacket or cotton clothing fabric, the antibacterial and warm-keeping fabric has the following advantages:

[0015] 1. The antibacterial and warm-keeping fabric utilizes the excellent conductive performance of the graphene of the second yarn, and, in combination with the fabric design ratio, can play an excellent antistatic effect in dry weather in winter.

[0016] 2. The antibacterial and warm-keeping fabric utilizes the double antibacterial effect of the graphene of the second yarn and the chitin in the first yarn, maximally improves the fabric antibacterial effect, and even if the consumer washes less, bacteria are not easy to breed.
