Abstract

UN METODO PARA LA PREPARACION DE UN NODE ALCOHOL (POLI)VINILICO QUE CONSISTE EN LOS PASOS DE (1) PREPARAR UNA SOLUCION DE POLIMEROS ACUOSA DE UN ALCOHOL (POLI)VINILICO DEFINIDO; (2) EXTRUIR LA SOLUCION DE POLIMEROS RESULTANTE BAJO CONDICIONES DEFINIDAS A TRAVES DE UNA MATRIZ QUE TENGA UNA PLURALIDAD DE ORIFICIOS PARA FORMAR UNA PLURALIDAD DE HEBRAS; (3) ATENUAR LAS HEBRAS RESULTANTES CON UNA FUENTE GASEOSA PRIMARIA DEFINIDA PARA FORMAR FIBRAS BAJO CONDICIONES DE TURBULENCIAS A MACROESCALA Y BAJO CONDICIONES SUFICIENTES COMO PARA PERMITIR QUE SE PRODUZCA LA VISCOSIDAD DE CADA HEBRAS A MEDIDA QUE SALE DE UN ORIFICIO DE LA MATRIZ Y UNA DISTANCIA NO SUPERIOR A 8 CM APROXIMADAMENTE, PARA AUMENTAR DE MANERA PROGRESIVA A MEDIDA QUE AUMENTA LA DISTANCIA DESDE LA MATRIZ, AL TIEMPO QUE SE MANTIENE SUSTANCIALMENTE LA UNIFORMIDAD DE LA VISCOSIDAD EN LA DIRECCION RADIAL, A UNA VELOCIDAD SUFICIENTE COMO PARA QUE SE PRODUZCAN FIBRAS CON UNA ATENUACION DESEADA Y CON UN DIAMETRO DE FIBRA MEDIO SIN QUE SE PRODUZCAN ROTURAS SIGNIFICATIVAS EN LA FIBRA; (4) SECAR LAS HEBRAS ATENUADAS CON UNA FUENTE GASEOSA SECUNDARIA DEFINIDA; Y (5) DEPOSITAR AL AZAR LAS FIBRAS RESULTANTES SOBRE UNA SUPERFICIE FORAMINOSA MOVIL PARA FORMAR UN TEJIDO SUSTANCIALMENTE UNIFORME, TENIENDO LA SUPERFICIE FORAMINOSA MOVIL DE 10 A 100 CM APROXIMADAMENTE DESDE LA APERTURA DESDE LA CUAL EMERGE LA ULTIMA FUENTE GASEOSA QUE ENTRA EN CONTACTO CON LAS HEBRAS, CUYAS FIBRAS TIENEN UN DIAMETRO DE FIBRA MEDIO QUE VA DE 0,1 APROXIMADAMENTE A 30 (MU)M APROXIMADAMENTE Y SUSTANCIALMENTE NO TIENEN TORNASOL, LLEVANDOSE A CABO LOS PASOS DE ATENUACION Y SECADO BAJO CONDICIONES DE TURBULENCIAS A MACROESCALA CONTROLADAS.
