Process for flameproofing organic fibre material

Claim 1

Composition for flameproofing organic fiber materials of cellulose/polyester, which essentially comprises 1. from 200 to 750 g/l of a tetrakis-(hydroxymethyl)-phosphonium compound, its self-condensation product or its condensation product with a reactive nitrogen compound, 2. from 3 to 20 g/l of an agent for imparting a soft handle, of the formula ##EQU19## wherein X o and Y o each are hydrogen, alkyl with 1 to 4 carbon atoms or --CONH 2 , Z o is hydrogen, alkyl with 1 to 4 carbon atoms, --CONH 2 , --C II OR' o or --A 4 --NHCO--R" o , A 1 , A 2 , A 3 and A 4 each are alkylene with 2 or 3 carbon atoms, D o is hydrogen, --OH, --NH 2 , --NH--CO--NH 2 , --CONH 2 , --CO--NH--CO--NH 2 , --(OCH 2 --) m-1 --CO--NH--R'" o or --(OCH 2 --) m-1 --NH--CO--R'" o , R o , R' o , R" o and R '" o each are alkenyl or alkyl with 9 to 23 carbon atoms, and m and n each are 1 or 2 and X o can also be a covalent bond to C I when H on N I and O on C I are omitted and there is a double bond between N I and C I , and Y o can also be a covalent bond to C II when Z o is --C II OR' o , H on N IV and O on C II are omitted and there is a double bond between N IV and C II , these softeners being present as tertiary amines or being quaternised by alkyl halides or dialkyl sulphates which possess 1 or 2 carbon atoms per alkyl radical or halogeno-carboxylic acid alkyl esters which contain up to 4 carbon atoms in the acid part and up to 22 carbon atoms in the alcohol part or up to 60 carbon atoms if the alkyl chains are interrupted by oxygen atoms, or being in the form of acid salts of alkylcarboxylic acids with at most 4 carbon atoms, and
