1. for the treatment of textile material to give the method for fire resistance, the method comprises the following steps:

  • A (), by the aqueous impregnation of this material finishing agent, this finishing agent is poly-(hydroxyl is organic) phosphonium compounds;

    B () is by dry for the material through dipping;

    C the material through dipping of drying is solidified to produce the insoluble polymer solidified with ammonia by (), this polymer machinery ground is fixed in the fiber of this material;

    D the polymer of solidification is oxidized, so that three valent phosphors is transformed into pentavalent phosphorus by ();

    E () washing is this material dry also;

    Wherein step (d) and one of (e) or both cause the common generation of aqueous stream effluent;

    Wherein controlled condition improves 0.8 or more to make the N;

    P atomic ratio that this material exists in step (c) process.
