Abstract

PROCEDIMIENTO PARA LA PREPARACION DE UNA FIBRA SPANDEX PROTEGIDA FRENTE A LA DECOLORACION INDUCIDA POR LA NIEBLA INDUSTRIAL O POR EL CALOR. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE DISUELVE UN POLIMERO SPANDEX EN UN DISOLVENTE ORGANICO; SEGUNDA, SE DISPERSA UN ANTIOXIDANTE FENOLICO Y UN FOSFITO EN LA SOLUCION ASI FORMADA, SIRVIENDO EL FOSFITO PARA AUMENTAR LA RESISTENCIA A LA DECOLORACION DE LA FIBRA INDUCIDA POR EL CALOR O LA NIEBLA INDUSTRIAL; Y POR ULTIMO, SE HILA EN SECO LA SOLUCION FORMADA, A TRAVES DE ORIFICIOS, PARA FORMAR FILAMENTOS. EL FOSFITO UTILIZADO ES UN FOSFITO DE DIALQUILO Y FENILO, EN EL QUE POR LO MENOS LA MITAD DE LOS GRUPOS ALQUILO ESTAN RAMIFICADOS EN LA POSICION ALFA Y LOS GRUPOS FENILO NO LLEVAN SUSTITUYENTES O ESTAN MONOALQUILADOS.
