A stable moulding or spinning material (I) is claimed, contg. 5-35 wt.% cellulose, 95-50 wt.% tert.-amine oxide, esp. N-methyl-morpholine N-oxide (NMMO) and water to make up 100 wt.% as required, together with a stabiliser (III); the novelty is that (III) is a cpd. of the following formula R1 = H, OH or a mono- or poly-saccharide residue with a pyranoside or glycoside linkage; R2-R6 = H or OH. (III) is a flavone cpd., esp. rutin (3, 3', 4', 5, 7-pentahydroxyflavone 3-rutinocide), quercetin (3', 3, 4', 5, 7-pentahydroxyflavone or morin (2', 3, 4', 5, 7-pentahydroxyflavone), pref. in amts. of 0.001-1.5 wt.% wt.% w.r.t. (I). |
