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 μm.

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 that pass through a type 200 mesh;
- b) diluting said blend of cellulose nano-filaments or said blend of cellulose micro-filaments to a target consistency;
- c) fractionating said diluted blend of cellulose nano-filaments or said diluted blend of cellulose micro-filaments into, at least, a fraction having an average length of at least about 25 μm;
- and,
- d) collecting said fraction having an average length of greater than at least about 25 μm.
