WATER ABSORBENT COMPOSITE SHEET AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a water absorbent composite sheet having a high water absorbing speed, enhanced in water absorbing quantity, having a flexible feeling and suitable for use in a paper diaper or the like. SOLUTION: The water absorbent composite sheet is constituted of a water absorbent sheet obtained by fixing water absorbent resin particles to a fibrous base material and the fibrous base material sheet bonded to at least one side of the water absorbent sheet. The water absorbent sheet and the fibrous base material sheet are preferably mutually bonded by thermally compressing both sheets using a pair of rolls at least one of which is heated. It is preferable to apply an uneven pattern to the surface of one roll. COPYRIGHT: (C)2005,JPO&NCIPI
