<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method for a dew absorbing sheet having a structure wherein water absorbing paper is disposed on the respective inside of two opposed polyolefin (PO) sheets and the particulates of a water absorbing polymer (SAP) are interposed between the pieces of the water absorbing paper. <P>SOLUTION: The manufacturing method comprises a process (A) wherein at least one PO sheet is a PO nonwoven fabric given water permeability and wherein the two PO sheets being wider than the water absorbing paper and having the same size are used and the particulates of the SAP are interposed between the pieces of the water absorbing paper so as to integrate the pieces of the paper, and a process (B) wherein the water absorbing paper is disposed at the center in the width direction of the respective inside of the two PO sheets and thereby the PO sheets are integrated with each other. The process (A) comprises means to scatter the particulates of the SAP on the surface of one piece of the water absorbing paper, to lay the other piece of the paper thereon, to spray water, on the occasion, on the surfaces of the paper to be laid on each other and to heat and contact-bond the two pieces of the paper laid on each other. The process (B) comprises a means to heat and contact-bond the surfaces of the two PO sheets laid on each other. <P>COPYRIGHT: (C)2004,JPO</p> |
