Abstract: 1,221,849. Fire-proofing. BADISCHE ANILIN-& SODA-FABRIK A.G. 1 July, 1968 [5 July, 1967], No. 31242/68. Heading D1P [Also in Division C2] Cellulosic fibrous materials are given a washresistant fireproof finish by applying thereto a composition consisting of a mixture of phosphoric amides having the general formula: wherein a is from 0.1 to 2.6, b is from 0.3 to 2.0 and c is from 0.1 to 1.0, the total of a b and c being 3.0. The flameproofing agent is generally used in a 5 to 50% by weight aqueous solution, the amount being such that the fibrous material absorbs from 5 to 50% by weight (with reference to the dry weight of the fibrous material) of the mixture of phosphoric amides. Application of the fireproofing agent to the fibrous material may be by dipping, spraying or padding. After the impregnated fibrous material has been dried, the agent is fixed thereon by. heating for two to twenty minutes at 100 to 200C. Following this, any un-fixed agent is removed e.g. by washing with hot dilute aqueous alkali-metal hydroxide solution or alkali metal carbonate solution. Cellulosic fibrous materials mentioned are cotton, linen, sisal, hemp, regenerated cellulose and wood-wool in the form of filaments, threads, fibres, wadding, non-woven fabrics or sheet materials such as textiles and papers. These materials may be mixed with others e.g. wool, silk, polyester, polyamide or polyacrylonitrile.
