A process for the production of regenerated cellulose fibers and the use of regenerated cellulose fibers produced by the process

摘要

Process for the production of regenerated cellulose fibers in the form of non-fibrillating cellulose filaments with a wet fibrillation grade of less than or equal to 2 and a loss of tensile strength in the wet state compared to that in the dry state, each measured to DIN 53816, of less than 40%, characterized that cellulose is dissolved in a direct solvent for producing a spinning solution and this spinning solution is wet or dry-wet-spun in a coagulation medium, wherein the coagulation contains a non-solvent of the cellulose and a non-soluble carbohydrate and thereby coagulation is delayed.
