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 °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.
Claims
57
AMENDED CLAIMS
[received by the International Bureau on 25 November 2002 (25.11.02); claim 25 added; remaining claims unchanged]
16. A process as claimed in claims 13 to 15, wherein the super- absorbent polymer particles of the blend formed in step (a) contain at least one odor control means.
17. A process as claimed in claims 13 to 16, wherein the fibrous web of step (b) contains at least one odor control means .
18. A process as claimed in claims 13 to 17, wherein, the blend formed in step (a) additionally contains a softening agent.
19. A process as claimed in claims 13 to 18, wherein the blend formed in. step (a) has a viscosity of from 20 to 1,000 mPas (measured at 20°C in a Brookfield viscometer, spindle 02, at 20 rpm) .
20. A process as claimed in claims 13 to 19, wherein the blend formed in step (a) is sprayable and has a viscosity of from 20 to 400 mPas (measured at 20°C in a Brookfield viscometer, spindle 02, at 20 rpm).
21. A process as claimed in claims 13 to 20, wherein the blend formed in step (a) is sprayable and has a viscosity o£ from 30 to 150 mPas (measured at 20°C in a Brookfield viscometer, spindle 02, at 20 rpm).
22. A disposable hygiene article containing an absorbent structure as claimed in one o£ claims 1 to 12.
23. A disposable hygiene article comprising a back sheet, an ab~ sorbent core and an absorbent article as claimed in one of claims 1 to 12 _
24. A disposable hygiene article as claimed in claim 22, wherein the absorbent article is used as acquisition layer, wicking layer and storage layer.
25. Use of a coated fibrous web obtainable by a process comprising
(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°C in a Brookfield viscometer, spindle 02, 20 rpm),
58
(b) applying said blend onto one or both sides of at least one fibrous web, and
(σ) subjecting said fibrous web to conditions under which the superabsorbent forming monomer will polymerize,
provided that the polymer loading on the web is more than 65 % by weight, with reference to the weight of polymer and web, as a storage layer in a disposable hygiene article.
