Provided is an absorbent article which includes a top sheet having extruded protrusions and a second sheet bonded to the top sheet and has adequate softness, satisfactory appearance, and yet prevents wrinkles in the top sheet along the MD. The problem is solved by a method of producing an absorbent article including forming the extruded protrusions through embossing of non-woven fabric to be a top sheet transferred by being drawn from downstream of a production line; and then bonding the non-woven fabric and a material of a second sheet in a bonding pattern formed by aligning the material of the second sheet 40 with the back face of the non-woven fabric having extruded protrusions, forming rows of plurality of top-second bonded portions at intervals in the CD in regions between the extruded protrusions adjacent each other in the MD so as to be provided across the center positions of the regions in the CD, and compressing the non-woven fabric in areas between the top-second bonded portions in the rows in the CD without welding of the non-woven fabric and the material of the second sheet.

An absorbent article comprising a topsheet comprising a first nonwoven material having a first visible element, a backsheet comprising a second nonwoven material having a second visible element, and an absorbent core disposed between the topsheet and the backsheet, wherein the first visible element and the second visible element are matching visible elements. Matching visible elements may enhance a caregiver's understanding of breathability and air flow between absorbent article components by indicating a pathway for air to flow.

An underpants-type disposable diaper has outer members that separately or integrally configures a front body and a back body. An inner member is attached to the outer members from the front body to the back body. The outer members have a waist extended section that extends to a side of the waist opening of an edge of the inner member on a waist side. The underpants-type disposable diaper further has a display sheet containing a liquid impervious resin film on an outer side of the inner member in a region in which the outer members and the inner member overlap with each other in at least one of the front body and the back body, in which the display sheet extends from a region overlapping the inner member into the waist extended section.

A hot melt adhesive for use on porous substrates, wherein the hot melt adhesive has about 10% to about 70% by weight of a polypropylene homopolymer having a DSC melting point of less than 100° C.; about 10% to about 60% of a first tackifying resin having a Ring & Ball Softening Point of about 95° C. to about 140° C.; about 0% to about 65% of a second tackifying resin that is different than the first tackifying resin; about 5% to about 50% of a plasticizer; about 1% to about 40% by weight of a secondary polymer which is either a semi crystalline polymer or wax with an enthalpy of fusion of greater than 30 Joules/gram; about 0.1% to about 5% of a stabilizer or antioxidant; wherein the components total 100% by weight of the composition, and the viscosity of the composition is equal to or less than about 20,000 centipoise (cP) at 163° C. (325° F.).

The present invention is intended to improve the dynamic fit of a crotch portion. The foregoing issue is solved in such a manner that a vertical stretchable part vertically extending and contracting in length is provided in a vertical intermediate portion of an absorber in a front body, an outer body of the front body has a portion overlapping at least the vertical stretchable part, width-direction both side sections of the portion, and a waist opening-side area of the portion and the sections, lifting elastic members having a contraction force of lifting a portion of the vertical stretchable part on a rear side of a front end toward width-direction both sides and an obliquely upward side at least when the diaper is worn are provided in the outer body of the front body on closer to lateral sides than to a width-direction intermediate portion of the absorber, and the vertical stretchable part vertically extends and contracts in length by elastic extension and contraction of the lifting elastic member.
