Abstract
The present description relates to a process of producing a dry mixed product comprising cellulose filament (CF) and a carrier fiber, and a dry mixed product of re-dispersible cellulose filament and a carrier fiber that permits the CF to retain its dispersibility in water and hence superior reinforcement ability in papermaking furnishes, composite materials, or other materials where CF is used. The process comprises mixing a water suspension of never-dried CF with a cellulose fiber pulp carrier followed by thickening to a suitable concentration so that it can be further processed and dried in a conventional device such as a dryer can of a pulp machine or a flash dryer.
