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.

A textile material to which has been applied a flame retardant composition that comprises:
- a water-insoluble, solid, aromatic, organic brominated compound,
- a wetting agent for said organic compound,
- a protective colloidal material, and
- a water medium wherein the brominated organic compound is suspended in finely divided form, with substantially all of the particles thereof under 10 microns in average diameter.
A textile material to which has been applied a composition that comprises
- a solid, water-insoluble, aromatic organic brominated compound,
- a wetting agent for the organic compound,
- a protective colloidal material, and
- a water medium wherein the brominated organic compound is suspended in finely divided form.
A textile material to which has been applied a composition having the ability to impart flame retardant characteristics thereto that comprises as a solid, water-insoluble, brominated organic component, a poly brominated biphenyl oxide, polybrominated biphenyl, polybrominated cyclododecane, polybrominated cyclohexane, polybrominated bisphenol A, or mixtures thereof;
- a wetting agent for said water insoluble brominated organic component;
- a protective colloid, and
- an aqueous medium wherein said brominated organic component is suspended in finely divided form.
A flame retardent textile material prepared by the process that comprises
- treating said material with a flame retardant composition including a brominated organic aromatic compound and a metallic oxide, in an aqueous dispersion, in admixture wih an aqueous emulsion of a high molecular weight polymeric adhesive binder;
- said brominated compound and said metallic oxide being solids at room temperature, finely divided and substantially water-insoluble,
- said high molecular weight polymeric binder being present in amount sufficient to secure said brominated organic compound and metallic oxide flame retardant composition to said material, upon drying and curing of said treated material, wherein the total amount of flame retardant deposited on said material is effective to reduce the flammability of the textile and is durable to laundering and dry cleaning.
