Beschreibung
Zusammenfassung:	A dispersion of cellulose fibers, a method of preparing the same and uses thereof. The dispersion is produced by providing a cellulose feedstock comprising cellulose fibers; by providing a mixture of an ionic liquid and a protic antisolvent for cellulose as a dispersion medium, the ionic liquid being selected from the group of protic salts of superbases capable of dissolving cellulose; and by mixing said cellulose feedstock into said dispersion medium so as to disperse the cellulose fibers therein to form a dispersion which is stable for at least 24 hours at room temperature. The dispersion can be used as an additive of cellulose pulps for making of fibrous products.
