Abstract

Composition for flameproofing organic fibre material which contains at least PA1 1. a tetrakis-(hydroxymethyl)-phosphonium compound, its self-condensation product or its condensation product with a reactive nitrogen compound PA1 2. an aliphatic amide or an imidazole or an imidazoline as agent for imparting a soft handle PA1 3. a methylolated amino groups containing 1,3,5-triazine and, optionally, PA1 4. an optionally methylolated and esterified derivative of a urea and, optionally, PA1 5. a low molecular amine. These compositions yield flameproof finishes paired with a soft handle especially on polyester-cotton blends.
