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.

As a new product, a composition having the ability to impart flame retardant characteristics to synthetic organic materials which 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.
As a new product, an aqueous medium composition having the ability to impart flame retardant characteristics to synthetic organic textile materials, which comprises by weight:
- a water-insoluble solid organic brominated compound, in an amount from about 50% to 75%,
- a wetting agent for the organic brominated compound, in an amount from about 1/2% to about 2.5%,
- a protective colloidal material, in an amount from 1% to 5% and,
- a water medium wherein the brominated organic compound is suspended in finely divided form, with substantially all of said particles under 2 microns in diameter.
As a new product, a composition having the ability to impart flame retardant characteristics to synthetic organic materials 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.
As a new product, a composition having the ability to impart flame retardant characteristics to synthetic organic materials, 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;
