Claims (9)
1. Vandabsorberende lagdelt struktur (10), omfattende en struktur i hvilken et absorberende lag (18,19) omfattende en vandabsorberende harpiks (12) og et klæbemiddel (16) er anbragt i sandwichkonstruktion med ikke-vævede stoffer (14, 15) på oversiden og undersiden af det absorberende lag (18, 19), hvilken vandabsorberende lagdelt struktur (10) omfatter: (1) et øvre ikke-vævet stof (14), som er et vandgennemtrængeligt ikke-vævet stof med en vandgennemtrængningsrate på 10 s eller mindre; og (2) et nedre ikke-vævet stof (15), som er et vandtilbageholdende ikke-vævet stof med en vandabsorption på 250 g/m2 eller mere, hvor det absorberende lag (18, 19) er inddelt i et primært absorberende lag (18) og et sekundært absorberende lag (19), med en åndbar lagdeling (17).
2. Vandabsorberende lagdelt struktur (10) ifølge krav 1, hvor den åndbare lagdeling (17) er et lag gennem hvilket den vandabsorberende harpiks (12) i det alt væsentlige ikke passerer.
3. Vandabsorberende lagdelt struktur (10) ifølge krav 1 eller 2, hvor den åndbare lagdeling (17) er fremstillet af PE eller PP fibre; porøs film; sanitetspapir; papirvæv; ikke-vævede stoffer med cellulose-indeholdende, syntetiske fibre; luftblæste, ikke-vævede stoffer fremstillet af papirmasse/PE/PP, eller ikke-vævede stoffer fremstillet af syntetiske fibre, rayonfibre, polyolefinfibre og polyesterfibre.
4. Vandabsorberende lagdelt struktur (10) ifølge krav 1,2 eller 3, hvor masseratioen mellem det primære absorberende lag (18) og det sekundære absorberende lag (19) er fra 98/2 til 20/80, fortrinsvis fra 95/5 til 25/75, og mest foretrukket fra 90/10 til 30/70.
5. Vandabsorberende lagdelt struktur (10) ifølge et hvilket som helst af kravene 1 til 4, hvor den vandabsorberende lagdelte struktur (10) har en tykkelse på 4 mm eller mindre i tør tilstand.
6. Vandabsorberende lagdelt struktur (10) ifølge et hvilket som helst af kravene 1 til 5, hvor det vandgennemtrængelige, ikke-vævede stof er et ikke-vævet stof fremstillet af polyolefinfibre eller af polyesterfibre.
7. Vandabsorberende lagdelt struktur (10) ifølge et hvilket som helst af kravene 1 til 6, hvor det vandtilbageholdende ikke-vævede stof er et ikke-vævet spunbond-stof, som er fremstillet af polyamidfibre, eller et ikke-vævet spunlace-stof, som er fremstillet af rayonstoffer som en hovedbestanddel.
8. Vandabsorberende lagdelt struktur (10) ifølge et hvilket som helst af kravene 1 til 7, hvor klæbemidlet (16) er mindst ét element valgt fra gruppen bestående af ethylen-vinylacetat-copolymer-klæbemidler, styrenbaserede elastomer-klæbemidler, polyolefinbaserede klæbemidler og polyesterbaserede klæbemidler.
9. Absorberende artikel (33), som omfatter den vandabsorberende lagdelte struktur (10) ifølge et hvilket som helst af kravene 1 til 8 anbragt i sandwichkonstruktion mellem et væskegennemtrængeligt lag og et væskeuigennemtrængeligt lag.
