  • Publication number: 20100304030
    Abstract: A process for flame-retardant finishing of fiber materials, for example wovens, is described. A tetrakishydroxymethylphosphonium compound is applied to the fiber material. This is followed by a treatment first with ammonia and then with an oxidizing agent. The fiber material is also treated with an acidic aqueous solution in the course of the process. The fiber materials obtained have good flame-retardant properties and a low formaldehyde content.
