According to a nonwoven fabric substrate () for wiping sheet of the invention, ridges () and grooves () are alternately formed at positions corresponding to each other on both surfaces (), and apertures () are formed in the grooves (). Each of the ridges () and the grooves () extend parallel to one side of the nonwoven fabric substrate (). Each of the grooves () alternately includes an aperture portion () which has a plurality of the apertures (), and a non-aperture portion () which has no aperture () and is longer than a distance between the nearest end portions of the adjacent apertures () in the aperture portion (). An arrangement pattern of the aperture portion () and the non-aperture portion () provided in the groove () is different from an arrangement pattern of the aperture portion () and the non-aperture portion () provided in an adjacent groove (). When the whole of the nonwoven fabric substrate () is seen in planar view, the nonwoven fabric substrate () has an aperture region () formed by the aperture portions () of a plurality of the grooves (), and a non-aperture region () formed by the non-aperture portions () of a plurality of the grooves (). Each of the aperture region () and the non-aperture region () is arranged in a predetermined pattern.

Non-woven fabric substrate for wiping sheet

Provided is a nonwoven fabric substrate () in which ridges () and grooves () are alternately formed at positions corresponding to each other on each of both surfaces (), and apertures () penetrating the grooves () of both surfaces are formed. The ridges () and the grooves () extend parallel to each other. The ridges () and the grooves () extend in a direction intersecting with each of a pair of both sides () extending in parallel of the nonwoven fabric substrate (). In planar view, each of the grooves () alternately includes an aperture portion () which has a plurality of the apertures (), and a non-aperture portion which has no aperture () and is longer than a distance between the nearest end portions of the adjacent apertures () in the aperture portion (), and arrangement patterns of the aperture portion () and the non-aperture portion () provided in the adjacent grooves () are different from each other. When the nonwoven fabric substrate () is seen in planar view, the nonwoven fabric substrate () has an aperture region () formed by the aperture portion () of the plurality of grooves (), and a non-aperture region () formed by the non-aperture portion (), and the aperture region () and the non-aperture region () are arranged in a predetermined pattern.

A wet cleaning sheet comprises an aqueous liquid-retaining layer having an aqueous liquid-containing polymer and a chemical-containing layer or containing a chemical which causes the polymer to release the aqueous liquid. The aqueous liquid-retaining layer and the chemical-containing layer or are formed and/or arranged in such a manner that they are kept out of substantial contact under no load applied but brought into contact with each other with a prescribed load applied whereby the aqueous liquid is gradually released from the polymer by the action of the chemical.

A process for producing bulky paper comprising the steps of transferring a fiber web ( ) having a water content of 50 to 85% by weight to a patterning zone having a perforated patterning net ( ) revolving along a suction unit; patterning the fiber web ( ) in conformity to the perforated patterning net ( ) by sucking the fiber web ( ) which is held on the perforated patterning net ( ) while applying 5 kcal/kg or more of heat to the fiber web ( ) in a heat application zone simultaneously with or before or after the sucking of the fiber web ( ); and then drying the fiber web ( ) in a drying zone to obtain patterned bulky paper ( ).

Process for producing bulky paper

A detergent composition, which exerts sufficient detergency and foaming power even in the presence of oily stains comprising an amide ether carboxylate component (a) and an amide ether component (b), wherein the weight ratio of the content of the component (a) to the content of the component (b) is from 0.1 to 100; the molar ratio of the total divalent metal salt ions (X) in the whole composition and to total anionic surfactants (Y) including the component (a) is from 0.025 to 10; and the composition contains substantially no glycerol or glycerol ether component (z) or the content of said component (z) is not more than 10% by weight based on the sum of the contents of the components (a), (b) and (z) as defined in the specification.
