Abstract:
A process for improving high aspect ratio cellulose filament blends comprising the steps of: a) providing a blend of cellulose nano-filaments or blend of cellulose micro-filaments; b) diluting the blend of cellulose nano-filaments or the blend of cellulose micro-filaments to a target consistency; c) fractionating the diluted blend of cellulose nano-filaments or the diluted blend of cellulose micro-filaments from the step c); and, d) collecting the fraction of the diluted blend of cellulose nano-filaments or the diluted blend of cellulose micro-filaments from the step c) having an average length of greater than at least about 25 .mu.m.
