Process for making a non-woven, wet-laid, superabsorbent
polymer-impregnated structure
摘要:
The instant invention is directed to a process for making a non-woven, wet-laid, superabsorbent polymer-impregnated structure. The process generally comprises the steps of: mixing; deliquifying; and drying. Specifically, fibers, superabsorbent polymers, and a liquid are mixed to form a furnish. The liquid is treated with a means for inhibiting the swelling of the superabsorbent polymer. Then, the furnish is deliquified to form a preformed structure. The preformed structure is dried to form the non-woven, wet-laid, superabsorbent polymer-impregnated structure.
