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.

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.
Claim 3
Dependent Claim
57 words
A textile material as claimed in claim 1 in which the water insoluble organic brominated compound is present in an amount of from about 50% to about 75%, the wetting agent is present in an amount from about 1/2% to about 2.5%, and the protective colloidal material is present in an amount from about 1% to 5%.
Claim 4
Dependent Claim
45 words
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.
Claim 5
Dependent Claim
45 words
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.
Claim 6
Dependent Claim
73 words
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.
Claim 7
Dependent Claim
73 words
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.
