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&#xb0; 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.

Process for manufacturing low-fibrillating cellulosic fiber

Provided is a process for the preparation of flame retardant cellulosic product including the steps of adding a soluble salt of silica to viscose, followed by blending and extruding the blended viscose into a spin bath, regenerating the viscose and subjecting the regenerated viscose to a step of glow proofing with polyaluminium compounds to obtain the flame retardant cellulosic product.

Process for preparing a flame retardant and glow resistant zinc free cellulose product

A flame retardant and glow resistant zinc free cellulose product containing silica, modified with polyaluminium ions. In the preparation of product the cellulose solution (viscose) and sodium silicate are blended and regenerated to obtain a polymeric silica in the cellulose structure which is further modified with polyaluminium ions to attach aluminium sites on silica molecules to make the product glow resistant and impart wash fastness as well.
