Title:
METHOD FOR PRODUCING WATER-ABSORBING COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2004/022840
Kind Code:
A1
Abstract:
A method for producing a water-absorbing composite which comprises the steps of (A) and (B): (A) a step of spraying an aqueous monomer solution containing acrylic acid and/or its salt onto a fibrous substrate having been raised by heating, to thereby allow the fiber constituting the fibrous substrate to carry drops of the aqueous monomer solution, and (B) a step of polymerizing the monomer present in the drops, to thereby prepare the water-absorbing composite having water-absorbing resin particles attached to the fiber; a method for producing a heat-compressed water-absorbing composite which comprises a step (C) of compressing the above water-absorbing composite while heating; and a method for producing a laminate type water-absorbing composite which comprises a step (D) of compressing a laminate prepared from the water-absorbing composite and another fibrous substrate while heating, to fuse the composite with the another substrate.
