Abstract

The present invention relates to a process for the production of continuous fibres or filaments based on cellulose acetate resistant to combustion and textile articles obtained therefrom, comprising the dissolution in acetone of an organic halogen-derivative additive, the dosing and mixing of said solution in the acetone solution of cellulose acetate and spinning under suitable conditions.
