Claims (12)

1. Klæbende absorberende forbinding omfattende et absorberende ikke-vævet materiale (6) og et beskyttende substrat (4), som er uigennemtrængeligt for væsker, men gennemtrængeligt for vanddamp, kendetegnet ved, at: - substratet (4) er dannet ved at samle en kontinuert film (4a) og en åben forstærkning, som er belagt, på i det mindste en af sine overflader, med en klæbende silikonegel (4b), uden at blokere åbningerne i forstærkningen, hvilken forstærkning dækker hele overfladen af filmen, - at forbindingen også omfatter et ikke absorberende flor (5), og et komplementært ikke-vævet materiale (7), som er fastgjort til hinanden langs deres periferi under indeslutning af det absorberende ikke-vævede materiale uden at være fastgjort ved noget punkt til sidstnævnte, og - at det ikke absorberende flor (5) klæber til den klæbende silikonegel (4b), som er belagt på forstærkningen.
2. Forbinding ifølge det foregående krav, kendetegnet ved, at det ikke absorberende flor (5) har en fladevægt på imellem 15 og 50 g/m2.
3. Forbinding ifølge ethvert af de foregående krav, kendetegnet ved, at fladevægten for den klæbende silikonegel er imellem 100 og 500 g/m2.
4. Forbinding ifølge ethvert af de foregående krav, kendetegnet ved, at det komplementære ikke-vævede materiale (7) er valgt blandt hydrofile ikke-vævede materialer baseret på ikke-absorberende fibre, hvis fladevægt er imellem 15 og 50 g/m2.
5. Forbinding ifølge ethvert af kravene 1 til 3, kendetegnet ved, at det komplementære ikke-vævede materiale (7) er valgt blandt ikke-vævede materialer, som omfatter super-absorberende fibre og termisk bindende fibre.
6. Forbinding ifølge ethvert af de foregående krav, kendetegnet ved, at den åbne forstærkning (4b) er en strikvare, som er belagt med klæbende silikonegel på begge sine overflader og på hele sin overflade uden at blokere åbningerne i strikvaren.
7. Forbinding ifølge ethvert af kravene 1 til 5, kendetegnet ved, at den åbne forstærkning (4b) er en perforeret film, som er belagt med klæbende silikonegel på blot én af sine overflader, uden at blokere perforeringerne i filmen.
8. Forbinding ifølge ethvert af kravene 1 til 5, kendetegnet ved, at det absorberende ikke-vævede materiale (6) er centreret på substratet (4) for derved at tilvejebringe klæbende kanter.
9. Fremgangsmåde til fremstilling af en forbinding ifølge ethvert af de foregående krav, som består af fremstilling af substratet (4), fastgørelse af det ikke absorberende flor (5) og det komplementære ikke-vævede materiale (7) til hinanden under indkapsling af det absorberende ikke-vævede materiale (6), fortrinsvis uden at disse er fastgjort på nogen måde til sidstnævnte, og efterfølgende samling af det indkapslede absorberende ikke-vævede materiale (6) til substratet (4), på siden med det ikke absorberende flor (5).
10. Fremgangsmåde ifølge krav 9, kendetegnet ved, at det ikke absorberende flor (5) og det komplementære ikke-vævede materiale (7) er fastgjort til hinanden alene langs deres periferi ved hjælp af varme, ultralyd, højfrekvens eller med en klæber.
11. Fremgangsmåde ifølge krav 9 eller 10, kendetegnet ved, at substratet (4) samles med det indkapslede absorberende ikke-vævede materiale (6) i en lamineringsstation ved påføring af et tryk liggende fra 0 til 10 bar.
12. Fremgangsmåde ifølge ethvert af kravene 9 til 11, kendetegnet ved, at det ikke-absorberende flor (5) underkastes en corona-behandling umiddelbart efter at det er blevet afviklet.
