Process for fabrication of regenerated cellulose yarns derived from recycled waste feedstocks

A method for the production of cellulose yarns from recycling cellulose material, wherein the method comprises the following steps:

• (a) dissolution of the recycling cellulose material in solution containing at least a molten ionic liquid;
• (b) adapting the conditions such that active substances dissolved or dispersed in the solution containing molten ionic liquid or generated in situ in the solution containing molten ionic liquid act to degrade non-cellulose material initially contained in the recycling cellulose material and contained in the solution containing molten ionic liquid due to the dissolution of the recycling cellulose material, wherein the active substances are either already present during (a) and/or are added after (a) and before or during (b).
