The invention relates to a water-absorbing non-woven fabric and a preparation method thereof, and belongs to the technical field of non-woven fabric preparation. According to the water-absorbing non-woven fabric and the preparation method thereof, fermentation filtrate contains a large amount of amino and carboxyl, and the hydrophilic groups cover the fiber surface of a self-made non-woven fabricblank, so that the non-woven fabric has good water absorption; and viscous silica sol is continuously modified by using acrylic emulsion and sodium molybdate, silicon dioxide in the silica sol can besubjected to a cross-linking reaction with hydroxyl in acrylic resin to form a compact network structure, and meanwhile, colloidal silicon dioxide particles are subjected to a coordination cross-linking reaction with an anionic ligand in the sodium molybdate through hydroxy bonds or ether bonds to form a sol-type structure so that the non-woven fabric can be effectively filled with the silicon dioxide in a promoting mode,
