PROCESS FOR MANUFACTURING LOW-FIBRILLATING CELLULOSIC FIBER

The present invention provides a process for producing low fibrillating cellulose fibers by a dry-jet-wet spinning process wherein cellulose is treated with a solvent containing imidazolium ionic salt in a spinneret maintained at a temperature of 100-120° C. and the spun fibers drawn to the coagulat...

Zusammenfassung:	The present invention provides a process for producing low fibrillating cellulose fibers by a dry-jet-wet spinning process wherein cellulose is treated with a solvent containing imidazolium ionic salt in a spinneret maintained at a temperature of 100-120° C. and the spun fibers drawn to the coagulation bath containing ionic salt with the draw ratio less than 5, to produce fibers with fibrillating index less than or equal to 3.
