Abstract
Abstract A process for rendering synthetic materials, 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.
