Abstract
The present invention provides a composition having a base of cellulose formate capable of producing fibers or films, containing as a solvent one or more compounds selected from the group consisting of alkylsulfoxides, lactams, acyclic amides and cyclic derivatives of urea. The invention further provides a process for obtaining these fibers and films, and a regenerated cellulose fiber having a degree of substitution by formate groups of less than 3%. The fiber is useful for textile applications or in order to reinforce tires.
