Abstract
UN PROCEDIMIENTO PARA HILATURA EN MASA FUNDIDA DE FIBRAS DE POLIAMIDA PARA MODIFICAR SU TENIBILIDAD, QUE INCLUYE LOS PASOS DE ALIMENTAR UNA PRIMERA ESCAMA DE POLIAMIDA QUE TIENE UN PRIMER NIVEL DE TERMINAL AMINA EN UN EXTRUSOR FUNDIDOR DE TORNILLO, FUNDIR LA ESCAMA Y LUEGO EXTRUIR LA POLIAMIDA FUNDIDA DE FIBRAS, PARA MODIFICAR LA TENIBILIDAD DE LAS FIBRAS, QUE COMPRENDE LOS PASOS DE: A)CO-ALIMENTAR UNA SEGUNDA ESCAMA DE POLIAMIADA DEL MISMO TIPO DE POLIMERO PERO QUE TIENE UN DIFERENTE NIVEL DE TERMINAL AMINA EN EL EXTRUCTOR CON LA PRIMERA ESCAMA DE POLIAMIDA, SIENDO LA CANTIDAD Y EL NIVEL DE TERMINAL AMINA DE LA SEGUNDA ESCAMA TALES QUE CUANDO SE MEZCLA CON LA PRIMERA ESCAMA SE OBTIENE UNA MEZCLA QUE TIENE UNA TENIBILIDAD PREDETERMINADA;Y B) MEZCLAR Y FUNDIR LAS DOS ESCAMAS PARA FORMAR UNA MEZCLA HOMOGENA FUNDIDA ANTES DE EXTRUIR LA MEZCLA EN FUSION DANDO FIBRAS.
