Abstract
Keksintö koskee menetelmää selluloosamateriaalin valmistamiseksi, jossa menetelmässä: syötetään selluloosakuituja selluloosaraaka-aineena (1) järjestelmään, ja siirretään selluloosakuidut (1) ekstruuderiin (6), joka käsittää sekoitusosan (6a, 6b) ja/tai jauhatusosan (6d). Menetelmässä lisäksi annostellaan ainakin yhtä kemikaalia järjestelmään ennen ekstruuderia (6) ja/tai ekstruuderissa (6), ja annetaan selluloosakuitujen ja kemikaali(e)n reagoida ainakin osittain ekstruuderissa (6), jolloin reaktio tapahtuu ainakin 40 %:n sakeudessa, ja/tai annostellaan ainakin yhtä kemikaalia järjestelmään ennen ekstruuderia (6) ja/tai ekstruuderissa (6) ja sekoitetaan selluloosakuituja ja kemikaalia (kemikaaleja) ekstruuderin (6) sekoitusosassa (6a, 6b), jolloin sekoitusvaihe suoritetaan ainakin 40 %:n sakeudessa, ja/tai jauhetaan syötetyt selluloosakuidut ainakin osittain ekstruuderin (6) jauhatusosassa (6d), jolloin jauhatusvaihe suoritetaan ainakin 5 %:n sakeudessa. Keksintö koskee lisäksi järjestelmää selluloosamateriaalin valmistamiseksi. Keksintö koskee myös tuotetun selluloosamateriaalin käyttöä fibrilliselluloosamassan valmistuksessa.
