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

The description of the present invention provides a method for producing a dry blended product comprising cellulose filaments (CF) and carrier fibers， and the dispersibility of the CF in water， and thus excellent in papermaking of furniture， composites or other materials in which the CF is used. It relates to a dry mixed product of redispersible cellulose filaments and carrier fibers that allow to maintain the strengthening ability. Since this method involves mixing the water suspension of the never-dried CF with a cellulosic fiber pulp carrier and then thickening it to an appropriate concentration， it is further processed and dried in a conventional apparatus such as a pulp machine or a dryer which may be a flash dryer. Can be. 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.
