The present invention relates to a wet manufacturing method for a superabsorbent material, which comprises adding a strong acid or a strong base to a saline solution to adjust the ion concentration to 0.01 to 4.5 N, pH 0 to 6 or 8 to 14； Dispersing at least one superabsorbent polymer of acidic resin and basic resin, each of which is not completely neutralized with respect to the basic saline solution； layering and sucking the SAP dispersion into the mesh screen belt deposition part to form a woven fabric A step of washing； washing the woven fabric to a desired neutralization level using a basic solution and an acidic solution, respectively, in an SAP dispersion of acidic and basic saline solution； washing the woven fabric with water and suction； And the pH and salt concentration are such that SAP water absorption is about 30 g H2O / g SAP or less. The absorbent material of the present invention is used for kitchen paper, toilet paper, water-absorbing hygiene products, operating room mattress covers, food-absorbing mats, pharmaceutical-related products, and the like.
