Abstract: An absorbent article comprising at least one double-sided coated fibrous web having a storage layer on one side and an acquisition layer on the other side and/or a combination of at least two adhering double-sided coated webs with the proviso that one web has a storage layer on both sides and the other web has an acquisition layer on both sides wherein said layers are obtained by (a) forming a blend comprising one or more monomers forming superabsorbent polymers, superabsorbent polymer particles, water, and one or more initiators, said blend having a viscosity of at least 20 mPas (measured at 20 DEG C in a Brookfield viscometer, spindle 02, 20 rpm) (b) applying said blend onto a fibrous web and (c) carrying out the polymerization of the monomers forming superabsorbent polymers and a disposable hygiene article containing said absorbent article.

Abstract: A storage layer obtainable by a process including (a) forming a sprayable blend containing one or more superabsorbent forming monomers; superabsorbent polymer particles; water; and one or more initiators; (b) applying the sprayable blend to a fibrous web; and (c) subjecting the sprayed fibrous web to conditions under which the superabsorbent forming monomer polymerizes. The storage layer is used in absorbent articles to store aqueous fluids.

Abstract: Production of water-absorbing flat structure (A) based on hydrophilic foam involves compressing composite (B) to reduce thickness of (A) by not less than 50% and swelling by not less than 25% only in wet state. (B) is made by bonding nonwoven coated by in-situ polymerization to hydrophilic latex foam (C) before cure; forming superabsorbent polymer on flat, cured (C) by in-situ polymerization; or applying polymer with reactive side groups to flat, cured (C) and cure. Production of water-absorbing flat structure (A) based on hydrophilic foam involves compressing a composite (B) to reduce the thickness of (A) by not less than 50% and swelling again by not less than 25% only in the wet state. (B) is made by (i) bonding a nonwoven coated by in-situ polymerization to uncured hydrophilic latex foam (C) and curing (C) by heating (B); (ii) in-situ polymerization of monomers forming a superabsorbent polymer on flat, cured (C); or (iii) applying a polymer (D) containing reactive side groups to flat, cured (C) and curing (D) with crosslinker(s). Independent claims are also included for the following: (1) water-absorbing flat structures; and (2) hygiene articles containing these.
