Abstract
UTILIZACION EN LA FABRICACION DE ARTICULOS DE LYOCELL EXTRUIDO DE CELULOSA CON UN VALOR DE INDICE DE FLUJO EN TUBERIA (SEGUN SE DEFINE) FRENTE A UN INDICE DE FLUJO DE CHORRO (SEGUN SE DEFINE) QUE VA DE 0,85 A 6 Y QUE PUEDE OFRECER UNA SERIE DE VENTAJAS, CONCRETAMENTE EN EL TRANSPORTE DE SOLUCIONES DE CELULOSA Y EN LA ESTABILIDAD DEL TEJIDO. EL INDICE DE FLUJO EN TUBERIA TIENE COMO FIN VALORAR EL RENDIMIENTO DEL FLUJO DE UNA SOLUCION DE CELULOSA BAJO CONDICIONES REDUCIDAS DE CORTE QUE NORMALMENTE SE EXPERIMENTAN EN LAS TUBERIAS DE TRANSPORTE. EL INDICE DE FLUJO DE CHORRO TIENE COMO FIN EVALUAR EL RENDIMIENTO DEL FLUJO DE LA SOLUCION DE CELULOSA BAJO LAS CONDICIONES ELEVADAS DE CORTE QUE SE EXPERIMENTAN DURANTE LA EXTRUSION. LOS ARTICULOS DE LYOCELL EXTRUIDOS SE FABRICAN MEDIANTE UN PROCEDIMIENTO QUE CONSISTE EN LOS PASOS DE: (1) DISOLVER LA CELULOSA EN UN DISOLVENTE DE N-OXIDO DE AMINA TERCIARIA ACUOSA PARA FORMAR UNA SOLUCION; (2) EXTRUIR LA SOLUCION A TRAVES DE UNA BOQUILLA MEDIANTE UN ESPACIO DE GAS EN UN BAÑO COAGULANTE PARA FORMAR UN PRECURSOR DE LYOCELL EXTRUIDO; (3) LAVADO DEL PRECURSOR DE LYOCELL EXTRUIDO SIN EL N-OXIDO DE AMINA TERCIARIA; Y (4) SECADO DEL PRECURSOR DE LYOCELL LAVADO, CON LO QUE SE FORMA EL ARTICULO DE LYOCELL EXTRUIDO.
