    摘要: A process for the non-permanent flameproofing of organic fibrous materials with monoammonium or monoalkali metal salts of an alkylphosphonic acid is claimed. Monoammonium methyl- and ethylphosphonate are also claimed. The claimed process is suitable for a very wide variety of fibrous materials. The flame-retardants used according to the invention have no corrosive action and have excellent compatability with most other textile finishing agents.
