Abstract

Esitetään menetelmä. Menetelmä voi käsittää hydrofobisointiaineen lisäämisen märkään massaan; märän massan kuivaamisen, jotta saadaan kuivattua massaa; jossa kuivattu massa on tarkoitettu defibrilloitavaksi kuiduiksi, jotta saadaan modifioitu massa; tai menetelmä käsittää edelleen kuivatun massan defibrilloimisen kuiduiksi, jotta saadaan modifioitu massa.
