NOVELTY - Hot air cloth comprises polypropylene fiber, graphene oxide and polyethylene resin, where the graphene oxide is dispersed to form a single-layer structure, and is bonded with polypropylene fibers through polyethylene resin. The mass ratio of the polypropylene fiber and graphene oxide is 3:1-5:1. The amount of the polyethylene resin is 5-10 %mass. USE - The hot air cloth is useful for diaper. ADVANTAGE - The hot air cloth has excellent bulkiness, and prevents moisture back infiltration. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the hot air cloth for diaper, involving pouring 5-10 wt.% graphene oxide polyethylene nanoparticles and graphene oxide into a ball mill tank, and continuing to ball mill at 80-90 degrees C for more than 56 hours to obtain ball abrasives, soaking the ball abrasive in a saturated sodium bicarbonate solution at 40-45 degrees C, cooling to 30-32 degrees C, filtering, and freeze-drying in vacuum to obtain a dry filter cake, uniformly mixing polypropylene fiber and dry filter cake are based on a mass ratio of 3:1-5:1, opening and combing, raising the temperature to 120-150 degrees C, using hot air to shape, cooling, and discharging to obtain the product.
