Abstract (en)
[origin: EP1882760A2] The present invention relates to a process for the production in continuous of cellulose-based flame-retardant fibres or filaments and textile articles obtained therefrom, comprising the predispersion in water of an organophosphoric additive, the dosing and mixing of the aqueous predispersion in a solution of cellulose xanthogenate, the filtration of the mixed solutions and spinning in a regenerating and coagulation bath.
