A manufacturing process for a moisture-wicking fabric, characterized in that, Includes the following steps: Step 1: Weigh the raw materials according to the following weight proportions: 35-40 parts modified polyester filament, 20-25 parts functional yarn, and 8-12 parts polyester fiber. The modified polyester filament is prepared by: Polyester resin and modifier are melt-blended and extruded at a weight ratio of 100:5 at an extrusion temperature of 300℃ to obtain modified masterbatch; the modified masterbatch and toughening agent are blended evenly at a weight ratio of 10:1, and then melt-spun at a spinning speed of 2800m / min to obtain modified polyester yarn. The toughening agent is a styrene-butadiene-styrene block copolymer; Step 2: The modified polyester filament, functional yarn, and polyester fiber are woven into a knitted fabric using a circular knitting machine. Step 3: Set the knitted fabric at 115℃ for 50 seconds. Once the setting is complete, you will get a moisture-wicking fabric. The method for preparing the modifier is as follows: S01: Add 3-5 parts by weight of graphene, 2-4 parts by weight of diatomaceous earth and 1-2 parts by weight of sodium carboxymethyl cellulose to 5-8 parts by weight of chitosan solution with a mass fraction of 5%, stir evenly to obtain graphene compound solution. S02: The carbon nanotubes are first placed in a proton irradiation chamber and irradiated for 1 hour at an irradiation power of 350-400W. After irradiation, the irradiated carbon nanotubes are obtained. Irradiated carbon nanotubes and graphene compound solution were mixed at a weight ratio of 5:3 and ball-milled at a speed of 1500 r / min for 2 h. After ball milling, the mixture was filtered and dried to obtain the modifier. The method for preparing the functional yarn is as follows: S11: Add 1-2 parts by weight of silane coupling agent KH550, 2-5 parts of lanthanum oxide, and 3-5 parts of nano-attapulgite to 5-8 parts of sodium dodecylbenzenesulfonate solution, stir evenly, and obtain the modified solution. S12: Impregnate the spandex fiber in a modification solution that is 5-8 times its total weight. After impregnation, dry the fiber at 55-60℃ for 24 hours to obtain the modified spandex fiber. S13: Mix 65-70 parts by weight of modified spandex fiber and 10-15 parts by weight of combed cotton on a spinning machine to make composite yarn, and add 5-8 parts by weight of functional additives. Set the speed of the roving frame to 4000 rpm and the speed of the spinning frame to 5500 rpm. Finally, add 8-12 parts by weight of acrylic fiber on a doubling machine to make functional yarn. The preparation method of the functional additive is as follows: 2-3 parts by weight of titanium oxide, 3-5 parts by weight of aluminum borate whiskers and 2-3 parts by weight of boron nitride are mixed evenly and then sintered to obtain a functional sintered body. 5-8 parts by weight of functional sintered body and 6-9 parts by weight of sol solution were mixed and ball-milled at a speed of 1500 r / min for 2 hours. After ball milling, the mixture was filtered and dried to obtain the functional additive. The sol solution is prepared by mixing nano silica sol, sodium silicate solution and zinc nitrate solution in a weight ratio of 2:5:
