1. Förfarande för framställning av fibermassa frän lignocellu-losahaltigt material, som utgöres av gran eller uppvisar gran-vedskaraktär, innefattande ett impregneringssteg, vid vilket ligninmjukgörande kemikalie i form av vätesulfit eller sulfit, företrädesvis natriumsulfit (Na2SC>3), tillföres materialet för defibreringen av detsamma, i syfte att främst mjukgöra materialet, kännetecknat därav, att den ligningmjuk-görande kemikalien tillföres i form av en utspädd vattenlösning i sädan mängd, att den efter genomförd defibrering absorberade och vid massans fibrer bundna kemikaliemängden, räknat som vikt-% Na2SC>3, representerar en punkt inom omrädet ABCD vid raffinering i en ej trycksatt raffinör, vars malhustryck är i huvudsak atmosfärstryck, och representerar en punkt inom omrädet EFGH i fig 1 vid raffinering i en trycksatt raffinör, vars malhustryck motsvarar ett övertryck av ca 140 kPa.
2. Förfarande enligt patentkravet 1, kännetecknat därav, att den absorberade och vid massans fibrer bundna kemikaliemängden räknat som vikt-% Na2S03 avpassas tili granveds-halten i utgängsmaterialet och atmosfäriska defibreringsför-hällanden för att representera en punkt utmed den mellersta, tjocka prickstreckade linjen i fig 1.
3. Förfarande enligt patentkravet 1, kännetecknat därav, att den absorberade och vid massans fibrer bundna kemikaliemängden räknat som vikt-% Na2S03 avpassas tili utgängs-materialets granvedshalt och förhällandena vid raffinering i en trycksatt defibrator vid defibreringstrycket ungefär 140 kPa li
