[0009] Preferably, the antibacterial fiber is seaweed fiber.

[0010] Preferably, the plied yarn is formed by twisting modal fiber and soybean fiber.

[0011] More preferably, in the plied yarn, the addition ratio of the modal fiber to the soybean fiber is 1:(0.5-1).

[0012] Preferably, the skin-friendly layer has four routes as a cycle, and according to the arrangement order from the upper needle dial to the lower needle cylinder, the first route is: upper needle dial circle tissue, upper needle dial tuck tissue, floating thread tissue, floating thread tissue; the second route is: upper needle dial circle tissue, floating thread tissue, floating thread tissue, lower needle cylinder circle tissue; the third route is: floating thread tissue, upper needle dial circle tissue, lower needle cylinder circle tissue, floating thread tissue; the fourth route is: floating thread tissue, floating thread tissue, lower needle cylinder tuck tissue, lower needle cylinder circle tissue.

[0013] More preferably, the first route and the third route both use the first composite yarn; and the second route and the fourth route both use the second composite yarn.

[0014] The present invention adopts the above technical solution, and compared with the prior art, has the following technical effects:

[0015] The environmentally friendly waterproof fabric of the present invention adopts TPU waterproof membrane as the waterproof layer, and there is no need for waterproof treatment during the fabric finishing process; the skin-friendly layer of the present invention is woven by two yarns, and the antibacterial fiber is coated on the spandex core yarn, so that the first composite yarn has elasticity and can effectively inhibit bacteria; the core yarn of the second composite yarn is a polyester core yarn with an irregular cross-section, and its special cross-section makes the second composite yarn have excellent air permeability. In addition, the twisted yarn coated on the polyester core yarn makes the skin-friendly layer soft and comfortable. BRIEF DESCRIPTION OF THE DRAWINGS
