PROCESS AND APPARATUS FOR MAKING CHANNELED ABSORBENT ARTICLES
20230081149 · 2023-03-16 ·

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.

Formaldehyde free binder compositions with urea-aldehyde reaction products
11472987 · 2022-10-18 · ·

Binder compositions are described that contain (1) a reducing sugar and (2) a reaction product of a urea compound and an aldehyde-containing compound. A specific example of the binder compositions include dextrose and an imidazolidine compound such as 4,5-dihydroxyimidazolidin-2-one. The binder compositions may be applied to collections of fibers and cured to form a fiber-containing composite, such as fiberglass insulation.
