Abstract

PROCEDIMIENTO E INSTALACION PARA LA OBTENCION DE FIBRAS O HILOS DE CELULOSA, A PARTIR DE UNA SOLUCION DE CELULOSA. EL PROCEDIMIENTO COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE REALIZA EL HILADO EN HUMEDO DE UNA SOLUCION DE PARTICULAS DE CELULOSA EN DIMETILACETAMIDA (DMA) O 1-METIL-2-PIRROLIDONA Y CLORURO DE LITIO, PRENSANDOSE LA SOLUCION A TRAVES DE TOBERAS DE HILADO; SEGUNDA, SE ESTIRAN LOS HILOS FORMADOS A TRAVES DE UN BAÑO DE PRECIPITACION EN EL QUE SE PREVE UNA CONCENTRACION CRECIENTE DE RECIPITANTE QUE AUMENTA A LO LARGO DEL TRAYECTO DE ESTIRADO DE LOS HILOS; Y POR ULTIMO, SE TRATAN LOS HILOS ESTIRADOS EN UN BAÑO ALCALINO.
