Abstract
PURPOSE:To obtain a water absorbent pad, which can be easily manufactured by integrally molding by a method wherein flexible members made of water absorbent thermoplastic resin are hot-welded onto both the sides of a water absorbent and water retentive thermoplastic resin sheet. CONSTITUTION:An oblong and flat water absorbent pad 10 consists of a resin sheet 11 and water absorbent members 12 and 13, which are made of spongy polyvinyl chloride are installed on the upper and lower surfaces of the sheet 11. The sheet 11 has water absorption and water retention and is, for example, made of continuous carboxymethylcellulose filaments and has thermoplasticity and absorbs and retains water, when immersed in liquid such as water or the like, resulting in turning into gel. In order to manufacture the pad concerned, the water absorbent member 12, the sheet 11 and the water absorbent member 13 are piled up, for example, in the order named and seated on a lower surface plate 20, which also acts as an electrode, so as to be pressed from above the water absorbent member 12 with a mold 21, which also acts as an electrode, in order to hot-weld the sheet 11 and the respective water absorbent members 12 and 13 to one another. Finally, cutting-off is done along the outer peripheral edge of the hot-welded portion.
