Abstract

Procedimiento de tratamiento por amoníaco licuado de material fibroso, compuesto totalmente o en parte por fibras celulósicas naturales o regeneradas, caracterizado porque: se aplican tensiones sobre el material plastificado por el amoníaco licuado, se reducen estas tensiones y se lleva de nuevo el porcentaje de amoníaco en el material a un porcentaje comprendido entre 75 y 30% en peso, limitando la relajación del material hasta su vuelta al estado no plástico. Ase elimina el amoníaco del material no plástico en presencia de tensiones débiles, inferiors a aproximadamente 5% de la carga de rotura del material
