The invention discloses underpants capable of circularly absorbing water, relates to the technical field of underpants, and is suitable for women in a
menstrual period and people with
urinary incontinence. A circulation absorption leakage-proof
assembly is arranged on the
crotch and sequentially comprises a one-way water guide layer, a dispersion layer, a
water storage layer, a waterproof cloth bag, a waterproof cloth surrounding layer and a
skin-friendly fabric layer from inside to outside, and a circumferential waterproof net is arranged on the periphery of the middle of the circulation absorption leakage-proof
assembly. The one-way water guide layer and the dispersion layer rapidly conduct and disperse water, the
water storage layer efficiently absorbs and locks the water, the waterproof net prevents the water from diffusing all around, the waterproof cloth bag and the waterproof cloth surrounding layer form a double-leakage-proof barrier, and the
skin-friendly fabric layer guarantees the wearing comfort. The leakage-proof underpants solve the problems that existing related underpants are prone to
moisture diffusion, poor in leakage-proof effect and uncomfortable to wear, and are reasonable in structure, excellent in leakage-proof and absorption performance and high in practicability.
