ABSTRACT:
The present invention relates to a method of producing an absorbent member comprising feeding a superabsorbent polyer and pul fiber both in the form of a dispersion in an air stream, depositing the superabsorbent polymer and the pulp fiber in a recess by suction through a plurality of suction holes provided in the bottom of the recess and releasing the deposited aggregate from the recess. The bottom of the recess (50) has a first suction region having an open area ratio R1of 40 to 80% and a second suction region having an open area ratio R2of 2 to 20% with the ratio of R1to R2ranging from 70/30 to 99/1. The superabsorbent polymer and the pulp fiber are deposited on both the first and the second suction regions.The present invention also relates to an absorbent member comprising a superabsorbent polymer and pulp fiber.
