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.

In a method for loading fibers contained in a fiber suspension with an auxiliary agent by means of a chemical precipitation reaction, which is triggered by adding carbon dioxide, the carbon dioxide is produced with a purity of ≤ 99%, preferably ≤ 85%, and this carbon dioxide of the fiber suspension added.
