In various exemplary embodiments, the present disclosure provides organohydrogel fibers and a process for making the organohydrogel fibers. The organohydrogel fibers have a hydrophobic phase dispersed in a hydrophilic phase. The organohydrogel fibers contain at least one hydrophobic active pharmaceutical ingredient (API), and at least one hydrophilic API. The organohydrogel fibers can be formed into a non-woven or 3D printed patch and a replaceable backing can be attached to the patch to make an effective wound dressing. The wound dressing can deliver active pharmaceutical ingredients to the wound over a period of multiple days.

Disposable absorbent articles are disclosed herein having a first and second fold line. The disposable absorbent articles have a topsheet, a backsheet, and an absorbent system disposed therebetween. The absorbent system has a first absorbent core and a second absorbent core which may be configured in an offset manner. And, the absorbent system and/or the first and second fold lines may be configured with respect to the absorbent article to effect a caliper change in the folded article.

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 typically in the form of pockets, each mold comprising an insert therein, wherein the molds are in fluid communication with an under-pressure source except for said insert such that a suction zone is formed in areas neighboring 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. optionally further selectively 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 at least a portion of said insert is porous and is in fluid communication with a positive pressure source such that air is blown out of said insert to form an air cushion or air film around at least an uppermost surface of said insert and in that said absorbent material is thereby forced away from areas of the nonwoven web corresponding to said insert.
