Abstract

Procedimiento para la producción de hilos de rayón-viscosa que comprende las etapas de expulsar viscosa a través de una boquilla al interior de un baño coagulante; extraer el hilo resultante tratar el hilo con unos solución acuosa ácida a una temperatura no inferior a 45ºC para continuar la regeneración de la celulosa en los hilos; tratar éstos mientras se encuentran todavía en condiciones ácidas con una solución acuosa que contenga un agente oxidante; lavar los hilos para liberarlos prácticamente del agente oxidante y secar los hilos a continuaciónProcess for the production of rayon-viscose yarns that comprises the steps of expelling viscose through a nozzle into a coagulant bath; extracting the resulting yarn treating the yarn with an acidic aqueous solution at a temperature not lower than 45 ° C to continue the regeneration of cellulose in the yarns; treating these while still in acidic conditions with an aqueous solution containing an oxidizing agent; wash the threads to practically free them from the oxidizing agent and then dry the threads
