The invention discloses a skin-friendly low-permeability ES composite short fiber for a hot-air non-woven fabric surface layer. The ES composite short fiber has a skin-core structure and consists of acore layer and a skin layer, wherein the core layer comprises the following raw materials in parts by weight: 85-90 parts of polypropylene, 5-9 parts of ethylene propylene copolymer, 14-18 parts of acrylic acid-acrylamide super absorbent resin and 6-11 parts of inulin; and the skin layer comprises the following raw materials in parts by weight: 80-85 parts of polyethylene, 10-15 parts of methyl methacrylate grafted modified polyethylene, 8-12 parts of ethylene propylene copolymer, 4-7 parts of polyvinyl alcohol, 7-15 parts of superfine pearl powder and 12-17 parts of sodium polyacrylate superabsorbent resin. The skin-friendly low-permeability ES composite short fiber for the hot air non-woven fabric surface layer has the advantages of skin-friendly property, moisture absorption, breathability, elasticity, no irritation to skin, sanitation, antibiosis and the like; and the amount of reverse osmosis after water absorption is small, and the skin-friendly low-permeability ES composite short fiber belongs to the low reverse osmosis type.
