Abstract

Oppfinnelsen angår en fremgangsmåte for behandling av et. i. cellulosemateriale hvor materialet belegges med et beleggmiddel omfattende: a) poly(vinylalkohol); b) et ikke-sfærisk partikulært fyllstoff; og c) et tverrbindingsmiddel, vektprosentforholdet er 30-70% av a), 70-30% av b) og høyst ,7% av c), og utsetting av det belagte materiale for en herdeoperasjon for derved å danne et tverrbindings-sperrelag på cellulosematerialet. Oppfinnelsen angår også både et belagt materiale oppnådd v.h.a. beleggmiddelet og. i beleggmiddelet i seg selv, samt anvendelsen av det belagte materiale som et returpapir for direkte resirkulering til en masseløser.The invention relates to a method for treating a i. cellulose material where the material is coated with a coating agent comprising: a) poly(vinyl alcohol); b) a non-spherical particulate filler; and c) a cross-linking agent, the weight percentage ratio being 30-70% of a), 70-30% of b) and at most .7% of c), and subjecting the coated material to a curing operation to thereby form a cross-linking barrier layer of the cellulose material. The invention also relates to both a coated material obtained by the coating agent and. in the coating agent itself, as well as the use of the coated material as a return paper for direct recycling to a pulp solvent.
