Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania nanowłókien celulozowych i młyn do rozdrabniania nanowłókien celulozowych. Sposób wytwarzania nanowłókien celulozowych charakteryzuje się tym, że wstępnie rozdrobniona masa celulozowa jest poddawana obróbce enzymatycznej preparatem, który wykazuje większą aktywność ksynalolityczną niż celulolityczną. Młyn do rozdrabniania nanowłókien celulozowych charakteryzuje się tym, że tarcze rozdrabniające (1) mają powierzchnię roboczą gładką, przy czym docisk tarcz realizowany jest przez poduszkę pneumatyczną (4).
