8. Jonkin patenttivaatimuksen 1-7 mukainen menetelmä, jolloin kuivatun MFC lietteen kuiva-ainepitoisuus on vähintään 20 p-%, edullisesti vähintään 40 p-%, edullisemmin vähintään 40 p-%, ja vielä edullisemmin vähintään 60 p-%.
9. Jonkin patenttivaatimuksen 1-8 mukainen menetelmä, jolloin kuivattu MFC voidaan uudelleen dispergoida veteen ilman oleellista MFC materiaaliominaisuuksien heikkenemistä, jolloin kuivatun MFC:n uudelleen dispergoin-tia arvioidaan vertaamalla ei-kuivatun MFC:n ja kuivatun ja uudelleen disper-goidun MFC:n viskositeettiä ja transmissiota, jolloin viskositeetin tai transmission ero ei ole suurempi kuin 30 %, edullisesti ei ole suurempi kuin 20 %.
10. Jonkin patenttivaatimuksen 1-9 mukainen menetelmä, jolloin menetelmä suoritetaan liikkuvalla substraatilla niin, että MFC liete tai osittain kuivattu MFC liete asetetaan substraatille ja liikkuu substraatin mukana kuivausalueelle, jolloin absorboiva materiaali saatetaan kosketuksiin MFC:n kanssa tietyn ajanjakson ajan, jonka jälkeen absorboiva materiaali poistetaan ja valinnaisesti tämä operaatio toistetaan kuivatun MFC:n valmistamiseksi.
11. Jonkin patenttivaatimuksen 1-9 mukainen menetelmä, jolloin menetelmä suoritetaan liikkuvalla substraatilla niin, että MFC liete tai osittain kuivattu MFC liete asetetaan substraatille ja liikkuu substraatin mukana ensimmäiselle kuivausalueelle, jolloin ensimmäinen absorboiva materiaali saatetaan kosketuksiin MFC:n kanssa tietyn ajanjakson ajan, jonka jälkeen ensimmäinen absorboiva materiaali poistetaan ja saatu MFC liikkuu substraatin kanssa toiselle kuivausalueelle, jolloin toinen absorboiva materiaali saatetaan kosketuksiin MFC:n kanssa tietyn ajanjakson ajan, jonka jälkeen toinen absorboiva materiaali poistetaan kuivatun MFC:n valmistamiseksi.
12. Jonkin patenttivaatimuksen 1-11 mukainen menetelmä, jolloin poistet-tu(poistetut) absorbointimateriaali(t) regeneroidaan ja uudelleen käytetään ab-sorbointimateriaaleina.
