The invention discloses a preparation method for sweat-discharging moisture-conducting fabric. The preparation method comprises the following steps: enabling deformed section polyester fiber fabric tobe placed in hydrophilic finishing liquid, performing two-dipping two-rolling; taking out the deformed section polyester fiber fabric, washing, drying, and baking; placing the obtained fabric in aloefinishing liquid, dipping; taking out the fabric, washing, and drying, to obtain the sweat-discharging moisture-conducting fabric. The sweat-discharging moisture-conducting fabric provided by the invention is capable of enabling sweat not to be diffused in the inner surface layer of the fabric, but directly absorbed to the outer layer of the fabric for diffusing and evaporating, keeping the innerlayer of the fabric dry and comfortable relatively, and reducing the adhesion effect between a human body and the fabric, has good comfort and air permeability at the same time, and is capable of meeting wearing requirements of wide consumers, and solving moisture-permeable and heat-permeable problems of clothes.
