An absorbent article includes a chassis, an absorbent structure placed on the chassis and elastic elements attached under tension to the chassis so as to extend across an absorbent structure region of the chassis occupied by the absorbent structure and to extend outward beyond opposite side edges of the absorbent structure. An elongation percentage of the elastic elementsis relatively low in the absorbent structure region as well as in first side regions outside opposite side edges of the absorbent structure and the elongation percentage is relatively high in second side regions outside the first side region and gradually increases as the elastic elements draw away from the first side regions toward the second side regions.

Absorbent article and method for making the same

Disclosed is an absorbent article including a topsheet, a backsheet and an absorbent core positioned between the topsheet and the backsheet. The topsheet contains hydrophobic fibers and hydrophilic fibers shorter than the hydrophobic fibers. The hydrophobic fibers are thermally bonded to each other. At least a part of the hydrophilic fibers form aggregates that disperse in the sheet. At least a part of the hydrophilic fibers that form the aggregates are bonded to the surfaces of the hydrophobic fibers.

Absorbent article with hydrophilic aggregates in topsheet

Disclosed is a package including an absorbent article and a packaging member. The packaging member is formed of a nonwoven fabric composed of thermoplastic fibers. The nonwoven fabric has a plurality of heat-fused portions arranged thereon in a predetermined pattern. The heat-fused portions are formed by pressing and heat-fusing the nonwoven fabric. The nonwoven fabric has a tensile strength of from 4.5 to 20 N/25 mm in MD and from 4.5 to 15 N/25 mm in CD and has a breathability resistance of at least 0.04 kPa-s/m.

Package for absorbent article

A disposable garment includes an elastically stretchable outer panel and a body fluid absorbent inner panel. The two panels are connected to each other along front end portions as well as along rear end portions of the panels by means of elastically stretchable connector sheets extending between the front end portions and between the rear end portions of the two panels so that the outer panel may be stretchable together with the connector sheets.

Disposable garment

A body absorbent article such as a sanitary napkin including a topsheet having a skin-contactable surface, a skin-noncontactable surface and a plurality of liquid passages extending through the topsheet from the skin-contactable surface to the skin-noncontactable surface, wherein the topsheet comprises a base layer made of a hydrophilic thermoplastic synthetic resin film or nonwoven fabric and formed with the liquid passages and a flocked layer formed on a top surface of the base sheet.

Body fluid absorbent article

A topsheet used in a disposable body fluids absorbent garment comprises a plurality of first ribs extending in parallel one to another in one direction and a plurality of second ribs extending in parallel one to another so as to intersect the first ribs. Each pair of adjacent first ribs intersect each pair of adjacent second ribs to define an air- and moisture-permeably opened region around which at least one of the respective pairs of adjacent first ribs and adjacent second ribs have their crests configured so that, between each pair of adjacent intersections of the first and second ribs each of the crests underlies an imaginary straight line connecting this pair of adjacent intersections.
