Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA ELABORACION DE CUERPOS MOLDEADOS DE CELULOSA, COMPRENDIENDO EL INDICADO PROCESO LAS SIGUIENTES ETAPAS: (A) LA CELULOSA SE DISUELVE EN UNA SOLUCION ACUOSA DE UN OXIDO AMINO TERCIARIO, EN PARTICULAR NMETILMORFOLINA - N-OXIDO (NMMO), PARA FORMAR UNA SOLUCION DE CELULOSA QUE PUEDE SER MOLDEADA; (B) MOLDEADO DE LA SOLUCION DE CELULOSA Y GUIA DE LA SOLUCION DE CELULOSA MOLDEADA DENTRO DE UN BAÑO DE PRECIPITACION ACUOSA EN DONDE SE PRECIPITA LA CELULOSA, DE FORMA QUE SE OBTIENE UN CUERPO MOLDEADO Y SE UTILIZA EL BAÑO DE PRECIPITACION; (C) REGENERACION DEL BAÑO DE PRECIPITACION UTILIZADO, CON UNA SOLUCION DE OXIDO DE AMINO ACUOSO, REGENERADO, SIENDO FORMADO CON UTILIZACION EN UNA ETAPA (A) CONTRA LA CELULOSA DE DISOLUCION. LA INVENCION SE CARACTERIZA DE TAL MODO QUE EN LA ETAPA (A) SE UTILIZA UNA SOLUCION DE OXIDO AMINO ACUOSO REGENERADO QUE DISPONE DE UN PH EN LA ZONA DE LOS LIMITES SUPERIOR E INFERIOR DEFINIDOS, COMO UNA FUNCION DE CONCENTRACION DE OXIDO DE AMINO TERCIARIO, MEDIANTE LA ECUACION PH = - 0,0015 X A{SUP,2} + 0,2816 X A + F, A, SIENDO A LA CONCENTRACION DE OXIDO DE AMINO TERCIARIO EN LA SOLUCION ACUOSA, EXPRESADA EN TANTO % EN PESO DE SOLUCION ACUOSA, Y SATISFACIENDO LA CONDICION: 40 % MENOR IGUAL QUE A MENOR IGUAL QUE 86 %, Y CON PREFERENCIA MENOR IGUAL 70 % DE A MENOR IGUAL 80 %, Y TENIENDO EL VALOR 1,00 PARA EL LIMITE SUPERIOR Y -1,80 Y CON PREFERENCIA -1,00 PARA EL LIMITE INFERIOR.
