Abstract

Oppfinnelsen vedrører en fremgangmåte for fremstilling av papir eller ikke-vevd fra fibre omfattende trinnene å tilsette termisk ekspanderbare mikrosfærer omfattende et termoplastisk polymerskall og et drivstoff fanget deri på et råstoff omfattende fibere eller på et nett av fibere, danne papir eller ikke-vevd fra råstoffet eller nettet og påføre varme for å øke mikrosfærenes temperatur tilstrekkelig for dem til å ekspandere og derved øke bulken av papiret eller det ikke-vevde, hvori nevnte ekspanderbare mikrosfærer omfatter fra omtrent 17 til omtrent 40 vektprosent drivstoff og har en volum-midlere diameter fiia omtient 17 omtrent 35 ^m. oppfinnelsen vedrører også visse ekspanderbare mikrosfærer og bruk derav.The invention relates to a process for making paper or nonwoven from fibers comprising the steps of adding thermally expandable microspheres comprising a thermoplastic polymer shell and a fuel trapped therein on a raw material comprising fibers or on a web of fibers, forming paper or nonwoven from the raw material or the web and apply heat to increase the temperature of the microspheres sufficient for them to expand and thereby increase the bulk of the paper or nonwoven, wherein said expandable microspheres comprise from about 17 to about 40 weight percent fuel and have a volume average diameter of about 17 about 35 µm. The invention also relates to certain expandable microspheres and their use.
