A method for flame retarding a fabric comprising:
- applying a melamine-based compound to a fabric, wherein applying the melamine-based compound to the fabric further comprises curing with heat at oven temperatures of 330° F. or greater;
- separately applying a tetrakis(hydroxymethy)phosphomium (“THP”)-based compound to the fabric;
- and
- fixing the melamine-based compound and THP-based compound as a flame retardant in the fabric.
