A method of manufacturing a nonwoven including the steps of: forming a nonwoven web substantially comprised of continuous fibers; applying a bonding pattern to said nonwoven web using a smooth roll and a calender roll wherein said bonding pattern comprises a pattern having unbonded areas; and subjecting the side of said nonwoven web contacted by said smooth roll to a hydraulic treatment at a pressure of between 25 and 75 bars and a total energy of about 0.01-0.04 kwhr/kg., wherein said continuous fibers are comprised of between 97% and 98.5% by weight of an olefin resin comprising substantially of polypropylene and between 1.5% and 3% by weight of a whitener.

A nonwoven sheet is provided in a formation region of a target portion or a further wide region including the formation region of the target portion. The target portion is a composite of a nonwoven fabric as a base and loop pile fiber yarns which are woven and project from at least an external surface nonwoven fabric. The target portion is fixed to an outer nonwoven sheet forming the outside of a ventral part.

A sanitary napkin for women includes a permeable inner sheet, which comes into contact with the skin of a wearer to thus allow secretions to pass therethrough, an outer sheet fused to the inner sheet, and an absorption pad disposed between the inner sheet and the outer sheet to absorb the secretions passed through the inner sheet, the outer sheet being a nanolaminate film composed of a nanomembrane formed by electrospinning a polymer solution and a strength-reinforcing nonwoven fabric laminated on one side of the nanomembrane.

A cover nonwoven fabric covers a back surface of an inner member from between a front side outer member and the inner member to between a back side outer member and the inner member. In this cover nonwoven fabric, a large number of holes are provided at intervals. The holes penetrate the front surface and back surface from between the front side outer member and the inner member to between the back side outer member and the inner member. The front side outer member and the back side outer member have, at least at portions overlapping with the cover nonwoven fabric and not having any elastic member, a total luminous transmittance of 50% or more.

A disposable diaper 1 has an elasticized leg cuff 10 on each longitudinally extending, lateral side of the crotch portion C. The elasticized leg cuff 10 includes an elastic member fixing sheet 5, an elastic member 6, an inner sheet 31, and an outer sheet 32 in order from the skin facing side. The inner sheet 31 and the outer sheet 32 are bonded to each other via a plurality of longitudinally extending and laterally spaced bonds 7. The elastic member 6 is located between the elastic member fixing sheet 5 and the inner sheet 31 and arranged at a location that does not overlap the bonds 7.

An absorbent article such as a baby diaper comprising a three-dimensional laminate 30 having a first layer 1 intermittently bonded to a second layer 2 by a heterophase polymer. The topsheet comprises three-dimensional protrusions 9 in the first layer 1 which are not bonded to the second layer 2. The heterophase polymer has an enthalpy of fusion of at least 10 J/g. The laminate may be used on the wearer-facing side of the article as topsheet 24 and/or on the garment-facing side as part of the backsheet 26. The first layer may comprise natural fibers.

A nonwoven web for an absorbent article is provided. The nonwoven web comprises a first surface, a second surface, and a visually discernible pattern of three-dimensional features on the first surface or the second surface. The three-dimensional features comprise one or more first regions and a plurality of second regions. The one or more first regions are different than the plurality of second regions in a value of an average intensive property. The one or more first regions comprise a first line, a second line, and a third line extending at least partially intermediate the first line and the second line. The first line and the second line extend in substantially the same direction. The third line extends in a direction transverse to the first line and the second line.

The present invention covers a non-woven fabric for laminate on a polyethylene layer, such that a. it is comprised by a mixture of polypropylene hydrophobic and hydrophilic fibers; b. it is manufactured by means of a carding process followed by thermal bonding c. during the thermal bonding is engraved in at least 15% of its area d. has a minimum base weight of 13 gr/m.sup.2.

An absorbent article includes: an absorbent body that absorbs liquid; a back sheet, made of a nonwoven fabric, disposed on a wearer's non-skin side of the absorbent body; a leak-proof sheet provided between the absorbent body and the back sheet; and an anti-displacement adhesive portion formed with an adhesive, the adhesive provided on a non-skin side of the back sheet, the back sheet including a compressed region that is compressed in the thickness direction, the absorbent article further including a portion where the anti-displacement adhesive portion overlaps the compressed region, a leak-proof sheet adhesive portion formed, with an adhesive, on a skin side of the back sheet, the adhesive joining the back sheet and the leak-proof sheet, and a portion where the compressed region overlaps the leak-proof sheet adhesive portion.
