Abstract
Abstract A process and product for rendering synthetic material, of synthetic fibers or mixtures of the same flame resistant which entails employing water insoluble flame retardant agents which are treated as colorless pigments, reduced to extremely finely divided condition, suspended in aqueous medium and applied as such or as part of a dispersed dye paste to the fabric, dried and set in place.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
88 words
A composition for rendering a disperse dyeable, synthetic, heat stable thermoplastic, substantially hydrophobic polymeric substrate in the form of fibers or fabrics, flame retardant, that comprises: a water-insoluble organic flame retardant brominated compound, having a melting point above 100° C.; and a particle size of 10 microns or less in diameter; an aqueous medium wherein said fire retardant compound is suspended; one or more surfactants; and an inert, organic, water-soluble protective colloid in an amount sufficient to maintain said flame retardant compound in suspension in said aqueous medium.
Claim 2
Dependent Claim
88 words
A composition for rendering a disperse dyeable, synthetic, heat stable thermoplastic, substantially hydrophobic polymeric substrate in the form of fibers or fabrics, flame retardant, that comprises: a water-insoluble organic flame retardant brominated compound, having a melting point above 100° C.; and a particle size of 10 microns or less in diameter; an aqueous medium wherein said fire retardant compound is suspended; one or more surfactants; and an inert, organic, water-soluble protective colloid in an amount sufficient to maintain said flame retardant compound in suspension in said aqueous medium.
