Abstract

Bei einem Verfahren zum Beladen von in einer Faserstoffsuspension enthaltenen Fasern mit einem Hilfsstoff durch eine chemische Fällungsreaktion, die durch Zusetzen von Kohlendioxid ausgelöst wird, wird das Kohlendioxid mit einem Reinheitsgrad von ≤ 99 %, vorzugsweise von ≤ 85 %, erzeugt und dieses Kohlendioxid der Faserstoffsuspension zugesetzt.
