The super-hydrophobic flame-retardant cut-resistant stab-resistant fabric comprises an antibacterial warm-keeping fabric layer and a hydrophobic flame-retardant fabric layer arranged on the outer side of the antibacterial warm-keeping fabric layer; the antibacterial warm-keeping fabric layer is formed by mixing and weaving ultra-high molecular weight polyethylene curled short fibers, cotton fibers and antibacterial polyester fibers according to the mass fraction ratio of 6: 3: 1, and the hydrophobic flame-retardant fabric layer is formed by mixing and weaving ultra-high molecular weight polyethylene curled short fibers, cotton fibers and glass fibers according to the mass fraction ratio of 5: 3: 1. the ultra-high molecular weight polyethylene curled short fibers and the glass fibers are soaked in a hydrophobic solution and dried before being woven, and the problem that the use range of an existing cut-resistant and stab-resistant fabric is affected due to poor water resistance and air permeability is solved.
