Abstract
A composition containing cellulose formate and a solvent system. At a temperature at least equal to a value T.sub.f the composition is a solution, and at a temperature appreciably less than T.sub.f the composition is an elastic, thermoreversible gel. A process for preparing a regenerated cellulose article by the transformation of this composition. Gel spinning in order to obtain a fiber or a film. A regenerated cellulose fiber having an excellent resistance to fibrillation in particular, wherein the said fiber may be a monofilament fiber. These fibers or these films may be used in textile applications or in technical applications, for example for reinforcing other articles, particularly tires.
