ABSTRACT:
After overlaying an inner sheet of a coarse and bulky non-woven fabric on an outer sheet, super absorbent polymers (SAP) are dispersed on the inner sheet. Folding inwardly both the sides of the laminated body composed of the outer sheet and the inner sheet so as to face the inner sheet together to overlay both the ends together, the SAP are wrapped by means of the outer sheet and the inner sheet from the top and bottom thereof. Then, applying heat over the outer sheet, the outer sheet and the inner sheet are melted and bonded together while the inner sheet is melted and bonded together. Then, the bonding parts are formed in a given shape and SAP can be retained between the fibers of the inner sheet in a given area of the encircled region preliminarily encircled by the bonding parts.
