1. be used to handle textile material to give the method for fire resistance, this method may further comprise the steps:

  • (a) with the aqueous solution dipping of this material with finishing agent, this finishing agent is poly-(hydroxyl is organic) phosphonium compounds;

    (b) will be through the material drying of dipping;

    (c) material through dipping with drying solidifies the insoluble polymer that solidifies to produce with ammonia, and this polymer machinery ground is fixed in the fiber of this material;

    (d) with the cured polymer oxidation, three valent phosphors is transformed into pentavalent phosphorus;

    (e) washing and dry this material;

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

    Wherein controlled condition is so that the N that exists on this material;

    the P atomic ratio improves 0.8 or more in step (c) process.
