PROCESS FOR PRETREATING RECLAIMED COTTON FIBRES TO BE USED IN THE PRODUCTION OF MOULDED BODIES FROM REGENERATED CELLULOSE

The present invention is a method for pretreating recycled cotton fibers used in the production of molded articles from recycled cellulose， comprising a metal removal stage and an oxidative bleaching stage of recycled cotton fibers or pulp formed thereof， effective metal reduction and polymerization degree and brightness ) Is characterized by the adjustment of. Recycled cotton fibers treated according to the described method can be used alone as a raw material for the production of shaped bodies from recycled cellulose， or as a blend with conventional dissolved pulp. The present method enables technically smooth， safe and economically feasible spinning through a viscose or lyrecell process， and thus the present invention provides an efficient recycling path for cotton waste materials. A process for pretreating reclaimed cotton fibres to be used in the production of moulded bodies from regenerated cellulose， characterized by effective metal reduction and adjustment of the degree of polymerization and brightness， including a metal removing stage and an oxidative bleaching stage of the reclaimed cotton fibres or pulp produced thereof. Reclaimed cotton fibres treated according to the described process may be used alone or in blends with conventional dissolving pulp as raw material for the production of moulded bodies from regenerated cellulose. The process enables technically smooth， safe， and economically feasible spinning via the Viscose or Lyocell process， therefore， the current invention provides an efficient recycling pathway for cotton waste materials.
