Abstract: A process for producing cellulosic shaped objects includes extruding and coagulating a solution of chemical wood pulp in a tertiary amine oxide, and possibly a liquid that does not dissolve wood pulp and is miscible with the tertiary amine oxide, the solution capable of being shaped into objects, the process of producing the shapeable solution employing a first wood pulp with a higher degree of polymerization and a second wood pulp with a lower degree of polymerization, and whereby initially a solution of the first wood pulp with a higher degree of polymerization in the tertiary amine oxide and possibly non-dissolving liquid, and a composition containing the second wood pulp with a lower degree of polymerization, tertiary amine oxide, and possibly non-dissolving liquid, are prepared separately, and the solution and composition are subsequently at least mixed to obtain the shapeable solution.

Abstract: The invention pertains to a process for manufacturing cellulose molded mers wherein a solution dissolved in amine oxides is shaped in a nozzle and the shaped solution is led after an air gap into a precipitation medium. The molded solution is passed successively through at least two precepitation media, which are selected so that a slower coagualation takes place at least in the first precipitation medium than the final precipitation medium.

Abstract: Solvent-spun cellulose filaments from a solution of cellulose in a tertiary amine N-oxide and if necessary water with a strength of 50 to 80 cN/tex, an elongation at break of 6 to 25% and a specific breaking time of at least 300 s/tex.
