Abstract

PROCEDIMIENTO PARA PRODUCIR FILAMENTOS Y FIBRAS DE RAYON. SE PARTE DE UNA SOLUCION VISCOSA CON UN INDICE DE SAL DE ENTRE 2,5 Y 6 PREPARADA PARIENDO DE UNA RELACION DESEQUILIBRADA EN PESO DE HIDROXIDO DE SODIO RESPECTO A CELULOSA QUE OSCILA ENTRE 0,60 Y 0,87 EN UN BAÑO HILADOR COAGULANTE CONTENIENDO DE 0,8 A 3,9 POR 100 EN PESO DE ACIDO SULFURICO, CON UNA RELACION EN PESO DEL ACIDO DEL BAÑO HILADOR RESPECTO AL HIDROXIDO DE SODIO DE 0,20 A 0,66. LOS FILAMENTOS INCOMPLETAMENTE REGENERADOS RESULTANTES SON POSTERIORMENTE ESTIRADOS, COMPLETANDOSE LA REGENERACION. LOS FILAMENTOS Y FIBRAS DE RAYON OBTENIDAS TIENEN UN MODULO DE HUMEDAD DE AL MENOS 0,5 G0D Y UN ALARGAMIENTO EN HUMEDO DE UN 11 A UN 17 POR 100.
