Abstract
PROCEDIMIENTO PARA LA PRODUCCION DE FIBRAS CELULOSICAS, EN EL QUE UNA SOLUCION CALIENTE DE CELULOSA EN UN AMINO-OXIDO TERCIARIO ES HILADA EN FILAMENTOS QUE SON CONDUCIDOS POR UNA RANURA Y PUESTOS A CONTINUACION EN CONTACTO CON UN PRECIPITANTE PARA PRECIPITAR LA CELULOSA, DE MANERA QUE LOS FILAMENTOS SON EXTRAIDOS MEDIANTE ACCION DE UNA FUERZA Y ESTIRADOS EN LA RANURA, EJERCIENDOSE LA FUERZA CON EL PRECIPITANTE Y DEJANDOSE QUE EL PRECIPITANTE FLUYA EN LA DIRECCION EN LA QUE SON EXTRAIDOS LOS FILAMENTOS, HACIENDO QUE LOS FILAMENTOS ENTREN EN CONTACTO CON EL PRECIPITANTE. ESTE PROCEDIMIENTO SE CARACTERIZA PORQUE EN EL MOMENTO EN EL QUE EL PRECIPITANTE ENTRA EN CONTACTO CON LOS FILAMENTOS, SE DEJA QUE ESTE FLUYA A UNA VELOCIDAD QUE ES COMO MINIMO TAN GRANDE COMO LA VELOCIDAD DE EXTRACCION DE LOS FILAMENTOS. LA INVENCION SE REFIERE TAMBIEN A UN DISPOSITIVO PARA LA REALIZACION DEL PROCEDIMIENTO.
