Abstract

La invencion se refiere a un procedimiento para formar productos de extrusion de celulosa a partir de una solucion opticamente anisotropica que contiene de 94 a 100% en peso de los siguientes constituyentes: celulosa, - ácido fosforico y/o sus anhídridos, y -agua; extruyendo la solucion y luego coagulando los productos de extrusion formados; siendo tratados posteriormente los productos de extrusion de tal manera que después del tratamiento posterior los productos de extrusion tengan un grado de acidez que sea por lo menos igual a 7. Las fibras obtenidas mediante este procedimiento poseen estabilidad térmica particularmente buena y son adecuadas como material de refuerzo.
