Abstract

Procédé de fabrication de filaments, fibres et feuilles en cellulose régénérée par le procédé à la viscose. Il est caractérisé en ce que l'on élimine de l'alcalicellulose les ions de métaux lourds ayant une action catalytique en ajoutant un ou plusieurs agents complexants efficaces dans les conditions de l'alcalinisation, et on effectue le mûrissement et la sulfuration de l'alcalicellulose substantiellement en l'absence de tels ions. La courbe donne le pourcentage de cellulose à bas poids moléculaire non filable, formée par dégradation au cours du mûrissement de l'alcalicellulose en fonction de la teneur en fer.
