发明名称 Surface cleaning pad having zoned absorbency and method of making same
摘要 A method of forming a surface cleaning pad body comprising a matrix web of binder fibers and superabsorbent polymer particles is provided. The method comprises the steps of depositing a mass of binder fibers onto a conveyor, shielding all but a selected area of the mass of binder fibers, depositing superabsorbent polymer particles onto the selected area of the mass of binder fibers so as to disburse superabsorbent polymer particles throughout a thickness of the mass of binder fibers, and bonding the mass of binder fibers to form a web structure and to substantially contain the superabsorbent polymer particles, thereby providing a cleaning pad body with superabsorbent polymer particles substantially contained in a zone of the mass of binder fibers that occupies at least a portion of the thickness of the mass of binder fibers and the selected area. The method further comprises the step of applying an attachment device to the cleaning pad body, thereby configuring the pad body for attachment to a cleaning implement.
