A DRY MIXED RE-DISPERSIBLE CELLULOSE FILAMENT/CARRIER PRODUCT AND THE METHOD OF MAKING THE SAME

摘要

The present description relates to a process of producing a dry mixed product comprising cellulose filament (CF) and a carrier fibre, and a dry mixed product of re-dispersible cellulose filament and a carrier fibre 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 fibre 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.
