Abstract
Procedimiento para preparar fibras acrílicas pirorretardantes y muy brillantes de baja tendencia a mostrar las manchas, caracterizados porque comprende las etapas de: a) preparar una primera solución en un disolvente inorgánico acuoso de un primer polímero de acrilonitrilo formador de fibras conteniendo al menos un 50% en peso de acrilonitrilo, un monómero de vinilo conteniendo halógeno, pirorretardante, en una cantidad suficiente para impartir pirorretardancia dicha fibra y cualquier resto de un monómero de vinilo libre de halógeno, b) preparar una segunda solución en un disolvente acuoso de la misma sal inorgánica utilizada en el paso a) de un segundo polímero de acrilonitrilo con cualquier contenido de halógeno e incompatible con el citado primer polímero, conteniendo el segundo polímero al menos un 70% en peso de acrilonitrilo y cualquier resto de uno o mas monómeros de vinilo libres de halógeno, c) mezclar íntimamente dicha segunda solución en la primera solución para formar una composición de hilatura en la que el contenido del polímero es de un 98 a un 85% en peso de dicho primer polímero, y correspondientemente, de un 2 a un 15% en peso de dicho segundo polímero, dando dichos porcentajes un total de 100; d) extruir dicha composición de hilatura en un coagulante acuoso para formar filamentos de gel húmedo; e) lavar los filamentos de gel húmedo para eliminara el disolvente, f) estirar los filamentos de gel húmedo lavados para proporcionar una orientación adecuada, g)relajar en condiciones húmedas y calidas los filamentos de gel húmedo estirados y a continuación secara los filamentos relajados.
