The present invention is intended to make the deformation of the absorber at the crotch portion less prone to influence the waist side of the absorber and allow the waist side of the absorber to be easily rounded along the surface of the wearer's body. The foregoing issue is solved by a disposable diaper including an absorber in a crotch portion, a ventral-side portion, and a dorsal-side portion, wherein the absorber is divided in a front-back direction by width-direction slits continuing in the width direction provided on both front and back sides of the crotch portion, and concave portions recessed toward the waist side are formed in width-direction centers of waist-side edges of the width-direction slits.

PROCESS AND APPARATUS FOR MAKING CHANNELED ABSORBENT ARTICLES

A method for making an absorbent article comprising an absorbent core comprising one or more channels, the method comprising the steps of: i. providing a first endless moving surface comprising a plurality of molds, each mold comprising a non-porous insert therein, typically said insert having the inverse shape of said channel(s), wherein the molds are in fluid communication with an under-pressure source except for said insert; ii. feeding a first nonwoven web to said first endless moving surface and over one or more said molds; iii. depositing an absorbent material, comprising cellulose fibers and/or superabsorbent polymer particles, over at least a portion of said nonwoven web; iv. removing said absorbent material from areas of the nonwoven web corresponding to said insert; v. applying a second nonwoven web directly or indirectly over the absorbent material, or folding said first nonwoven web, such to sandwich said absorbent material between upper and lower layers of said nonwoven web(s); vi. joining said upper and lower layers together at least in the areas of the nonwoven web(s) corresponding to the insert to form an absorbent core having one or more channels substantially free of absorbent material; vii. optionally joining an acquisition distribution layer to said absorbent core, typically a skin facing surface of said upper layer; viii. optionally laminating said absorbent core and acquisition distribution layer between a liquid pervious topsheet and a liquid impervious backsheet; wherein step vi. comprises the step of selectively applying a first pressure onto the absorbent core, preferably only, in a central portion thereof and a second pressure, preferably only, along peripheral longitudinal side edges thereof miming opposite and parallel to each other and being outboard of said central portion, said central portion corresponding at least to a region of the core comprising said channel(s), and wherein said first and second pressures are successively applied along a machine direction (MD).

ABSORBENT ARTICLES AND METHODS OF MAKING

An absorbent article comprising an absorbent core sandwiched between a liquid permeable topsheet and a liquid impermeable backsheet, and an acquisition distribution layer positioned between said topsheet and said absorbent core, wherein the absorbent core comprises absorbent material selected from the group consisting of cellulose fibers, superabsorbent polymers and combinations thereof, wherein said absorbent core comprises at least one core wrap substrate enclosing said absorbent material, and wherein a top layer of said core wrap is adhered to a bottom layer of said core wrap to form one or more channels substantially free of said absorbent material, wherein said channels have a length extending along a longitudinal axis and the absorbent core has a length extending along said longitudinal axis and wherein the length of said channels is from 10% to 95% of the length of said absorbent core and wherein said channels each follow a substantially continuous path such as from a first end of a channel to a second end of the same channel wherein the acquisition distribution layer comprises a spunbond and/or carded nonwoven layer comprising synthetic fibers, wherein said synthetic fibers are comprised at a level of greater than 80% wt by weight of said acquisition distribution layer, and wherein said acquisition distribution layer has a basis weight of from 10 to 50 g/m.sup.2.
