Composition containing a cellulose formate capable of forming an elastic cellulose gel, process for making the composition and article made by the process

摘要

The present invention describes a composition containing cellulose formate and a solvent system. The composition is a solution at a temperature of at least equal to a value Tf, while the composition is an elastic, thermoreversible gel at a temperature appreciably less than Tf. The present invention further describes a process for preparing a regenerated cellulose article by the transformation of this composition. The composition is then formed into a fiber or a film by gelation. The resulting regenerated cellulose fibers have excellent resistance to fibrillation, in particular wherein the fiber may be a monofilament fiber. These fibers or films may be used in textile applications or in technical applications, for example to reinforce other articles, such as tires.
