Abstract
In a method for the flame-retardant treatment of fabrics by impregnation with a condensate of a tetrakis (hydroxyorgano) phosphonium salt and, e.g., urea, the addition of one or more protonated and neutralized amines to the impregnation solution increases the efficiency of fixation of the phosphonium salt within the fibers, improves its uniform distribution within the system and leads to improved flame-retardant and water-resistant properties.
