Abstract

PARA FABRICAR UN CUERPO CELULOSICO DE MOLDEO, SE PRESIONA UNA SOLUCION DE AMINOXIDO CELULOSICA A TRAVES DE UNA TOBERA, CONDUCIENDOLA POSTERIORMENTE A TRAVES DE UNA RANURA DE AIRE, DONDE PUEDE SER ESTIRADA. FINALMENTE ES COAGULADA EN UN BAÑO DE RELLENO. SEGUN LA INVENCION, EL DIAMETRO MINIMO DEL AGUJERO DE LA TOBERA UTILIZADA TIENE UN MAXIMO DE 150 MICRAS, PREFERENTEMENTE 70 MICRAS, SUPONIENDO LA LONGITUD DEL CANAL DE LA TOBERA AL MENOS 1000 MICRAS, PREFERENTEMENTE UNAS 1500 MICRAS. CON ELLO PUEDE REDUCIRSE LA LONGITUD DE LA RANURA DEL AIRE POR DEBAJO DE 35MM O HASTA POR DEBAJO DE 10MM, YA QUE A CONSECUENCIA DE UNA ORIENTACION EN LA TOBERA DEL CANAL LARGO, ES SUFICIENTE UN ESTIRADO MENOR SIN QUE SE PRODUZCAN EFECTOS NEGATIVOS SOBRE LAS CUALIDADES TEXTILES DE LAS FIBRAS FABRICADAS. UNA VERSION PREFERENTE DEL CANAL DE LA TOBERA, PREVEE UNA CARA DE ENTRADA CONICA Y SOLO LA CARA DE SALIDA CILINDRICA.
