Title:
PRODUCTION OF ABSORBENT AND APPARATUS THEREFOR
Document Type and Number:
Japanese Patent JPH08337954
Kind Code:
A
Abstract:

PURPOSE: To obtain an absorbent for sanitary use composed of pulp and a water-absorbing polymer homogeneously dispersed with each other in the direction of thickness.

CONSTITUTION: Crushed pulp is supplied through a crusher 3 into a duct 7 in which an air flow of a definite direction is generated by a suction pump 11. At the same time, a water-absorbing polymer is introduced into the duct 7 through a water-absorbing polymer feeding pipe 5 by the aid of the air flow and joined with the crushed pulp transfer flow to form a mixed flow. In the above joining process, the air flow containing the water-absorbing polymer is joined to the crushed pulp transfer flow at an angle between the right angle and the oppositely directing angle. A mixed flow containing homogeneously dispersed pulp and water-absorbing polymer is formed by this process. The mixed flow is supplied to a rotary deposition drum 9 of a molding process to form an absorbent having a prescribed form.
