    摘要： The problem to be solved by the present invention is to provide an absorbent article in which a reduction in liquid absorbency caused by the hydrophobicity of thermoplastic resin fiber is prevented through the use of thermoplastic resin fiber that includes unsaturated carboxylic acid, unsaturated carboxylic acid anhydride, or a mixture of these as a monomer component. The present invention solves this problem by providing a sanitary napkin provided with a top sheet, a back sheet, and an absorbent body disposed between the top sheet and the back sheet. The absorbent body has an absorbent material layer that contains a cellulose-based hydrophilic fiber and a thermoplastic resin fiber that includes unsaturated carboxylic acid, unsaturated carboxylic acid anhydride, or a mixture of these as a monomer component in a mass ratio of 90:10 to 50:50. The top sheet has an integrated section that is heat-treated together with the absorbent material layer so as to be integrated with the absorbent material layer.

    摘要： A device and method for excellent recovery of bulk in nonwoven fabric. While nonwoven fabric is transported so as to enter a heating chamber via an entry opening and, after progressing within the heating chamber, exit the heating chamber via an exit opening, heated air is supplied at a speed higher than the transport speed for the unwoven fabric so as to enter the heating chamber via the entry opening and after progressing within the heating chamber while contacting the nonwoven fabric, exit the heating chamber via the exit opening.
