A absorbent member manufacturing method of the invention is a method for manufacturing an absorbent member () including synthetic fibers (). The method involves: a transporting step of transporting a plurality of sheet fragments () including synthetic fibers () to an accumulating depression () by using a duct; an accumulating step of accumulating, in the accumulating depression (), the plurality of sheet fragments () transported in the transporting step, and forming an accumulation (') which is a constituent member of the absorbent member (); and a pressing step of pressing the accumulation (&#x2032;) over its entirety in the thickness direction.

Method for manufacturing absorbent body

An absorbent member manufacturing method of the present invention is a method for manufacturing an absorbent member () for an absorbent article and including synthetic fibers () and hydrophilic fibers (). The method involves: a transporting step of transporting the hydrophilic fibers () and a plurality of sheet fragments () to an accumulating depression () by using a duct (); an accumulating step of accumulating, in the accumulating depression (), the plurality of sheet fragments () and the hydrophilic fibers (), and obtaining an accumulation () which is a constituent member of the absorbent member (); and a depression forming step of forming a depression () in the accumulation () by applying pressure to a portion thereof. In the transporting step, the sheet fragments () and the hydrophilic fibers () are brought into contact with one another in an airflow created inside the duct (), and the sheet fragments () and the hydrophilic fibers () are transported by the airflow in a dispersed and airborne state in which the sheet fragments and the hydrophilic fibers are mixed.

Method for producing absorber and method for producing absorbent article

A lower face of a base body () includes a wave-like corrugated surface portion () of which cross-section in a direction perpendicular to a predetermined direction along which cleaning is performed with a cleaning device body () in a planar view is wave-shaped as having a ridge portion () and a valley portion () arranged alternately and continuously. The valley portion () of the wave-like corrugated surface portion () includes an oblique valley portion () of which end part is opened to a side portion of the base body () facing to the predetermined direction as being extended obliquely against the predetermined direction to obliquely guide objects such as dust to be stuck to a cleaning sheet () in accordance with wiping of the surface to be cleaned.

Cleaning device

Disclosed is a composite sheetcomposed of a substantially flat lower fibrous sheetand an upper fibrous sheetbonded to the lower fibrous sheet. The upper fibrous sheetis three-dimensionally textured with a number of projectionsand a number of depressioneach of which is located between every adjacent two of the projections. The projectionsand the depressionsalternate in both a first direction of the composite sheetand a second direction perpendicular to the first direction. Each projectionhas a pair of opposing first wallsparallel to the first direction and a pair of opposing second wallsparallel to the second direction. The basis weight of the first wallsis different from that of the second walls
