Abstract: A nonwoven fabric has: a base section that is spread in a flat manner and that comprises a first surface and a second surface opposite each other; and a plurality of protrusions that protrude from the first surface of the base section in the thickness direction. Each of the protrusions is provided with a peripheral surface section that rises from the first surface of the base section in the thickness direction and a peak surface section comprising a peak surface formed on the vertex of the protrusion. The fiber density of the peripheral surface section is higher than the fiber density of the peak surface section. At least part of a peak surface peripheral edge part of the peak surface section is configured as a thickest section having the thickest thickness of the nonwoven fabric.

Abstract: The present disclosure relates to a non-woven fabric that is formed from a base part that spreads out in a planar shape and from a plurality of projecting parts that protrude in a thickness direction (Th) from the base part. Each of the projecting parts has a projecting surface part. Each of the projecting surface parts is configured such that the fiber density of the projecting surface part increases toward one side in a prescribed direction that is a surface direction of the non-woven fabric.

Abstract: The present invention pertains to a nonwoven fabric that can effectively allow the passage of high-viscosity waste. The nonwoven fabric (1) is formed from a substrate (10), which extends in an approximately planar shape and has a first surface (FF) and a second surface (FS) positioned at the reverse side from the first surface, and a plurality of protrusions (12), which protrude from the substrate to the first surface side. The fiber density of the first surface side is greater than the fiber density of the second surface side at the apices of the protrusions.

Abstract: 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.

Abstract: The present invention provides an absorbent article that has flexible cushioning properties, favorable rebound when compressed, superior collection of waste, and superior liquid migration properties from a surface sheet to an absorbent element. The absorbent article has: a surface sheet, which has a textured structure used at the skin surface side of the absorbent article, and has first protrusions protruding to the skin surface side and second protrusions protruding to the clothing side at the reverse of the skin surface side; and an absorbent element disposed at a position overlapping the surface sheet in a plan view. The surface sheet and the absorbent element are joined in a planar manner at a join section at the apices of the second protrusions.

Abstract: An absorbent article contains a non-woven fabric sheet for an absorbent. The non-woven fabric sheet is produced without employing a strength-imparting means such as post-coating of an adhesive agent that can deteriorate a liquid diffusion property of the non-woven fabric sheet. The absorbent article includes a liquid-permeable surface sheet, a liquid-impermeable back sheet, an absorbent arranged therebetween, and the non-woven fabric sheet for the absorbent. The non-woven fabric sheet contains pulp, a pulp fiber layer, a first-surface-side fiber layer arranged on a first surface of the pulp fiber layer and mainly composed of hydrophilic fibers having an average fiber length of 25 to 64 mm, and a second-surface-side fiber layer arranged on a second surface of the pulp fiber layer and mainly composed of hydrophilic fibers having an average fiber length of 25 to 64 mm.

Abstract: 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.
