TL;DR: 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 latex medium and applied as such or as part of a dispersed dye paste to the fabric, dried and set in place.
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 latex medium and applied as such or as part of a dispersed dye paste to the fabric, dried and set in place. The active flame retardant agents are brominated organic chemical compounds, and reduced to a fine state of subdivision, preferably under two microns, average particle diameter, which compound is supported in an aqueous suspension with a colloidal protective agent, and thus, is in a form for blending in a binder, plastic resin latex, so that when the composition is dried and cured in place on the fabric, a very useful retardant effect is obtained which is durable to laundering and dry cleaning, and the hand of the fabric is preserved.

TL;DR: In this article, a fire bomber is fitted with a large container for storing longterm retardant, and a measuring tank is connected between the container and the drop tank of the aircraft; a small measured charge of retardant can thus be introduced into the drop tanks when required.
Abstract: A fire bomber is fitted with a large container for storing longterm retardant. A measuring tank is connected between the container and the drop tank of the aircraft; a small measured charge of retardant can thus be introduced into the drop tank when required. In use, the bomber, almost fully loaded with retardant, is flown to a lake close to a fire to be controlled. A small amount of water is taken on and mixed with the charge of retardant in the drop tank to produce a minimum effective load of retardant slurry. The bomber flies to the fire and drops the slurry thereon. It then returns to the lake to mix a new batch of slurry. This procedure is repeated until the supply of retardant is exhausted. The technique is useful in that its use enables a relatively slow amphibious bomber such as a Canso PBY, to drop as much long-term retardant on a fire as relatively high-speed bombers, such as an A-26 or TBM, operating from an airport.

TL;DR: In this paper, the effects of the retardant can be transferred to the untreated layer, and it was found that treating only one of the layers of synthetic fabrics resulted in almost as good and sometimes better reduction of burning rate as treating both layers to the same net add-on.
Abstract: Burning-rate measurements on double layers of the same fabric having one layer treated with flame retardant reveal that effects of the retardant can be transferred to the untreated layer. A system consisting of a layer of cotton sheeting treated with a phosphate flame retardant placed underneath a layer of untreated material burns at about the same rate as two identically treated layers with the same net average add-on. When this average is low, the combination bums more rapidly than two untreated layers, in accordance with evidence that inorganic phosphate retardants can increase the flame-propagation rate of cotton at low add-on levels. For the double layers of synthetic fabrics studied thus far, it was found that treating only one of the layers results in almost as good and sometimes better reduction of burning rate as treating both layers to the same net add-on. Such transfer effects need to be recognized and understood by those using flame retardants in practical heterogeneous textile systems.

TL;DR: In this article, the flame-retardant properties and thermal behavior of cotton cellulose finished with THPCamide, THPOH-amide, TPHC-cyanamide, and THPC-NH3 were investigated before and after five washes.
Abstract: The flame-retardant properties and the thermal behavior of cotton cellulose finished with THPC-amide, THPOH-amide, THPOH-NH3, and THPC-cyanamide were investigated before and after five washes. Phosphorus and nitrogen content, N/P ratios, and total add-on of finish were determined. Flammability properties were evaluated by the 45°C angle, the vertical strip, and oxygen index tests. Differential scanning calorimetry and thermogravimetric analysis were used to study the thermal behavior of the fabrics during pyrolysis. Infrared spectra of samples before pyrolysis and at significant points in the pyrolysis reaction were used to obtain further information regarding the pyrolysis reaction. The THPC-amide, THPOH-amide, and THPC-cyanamide finishes appeared to react in a similar manner to impart flame-retardant properties to the fabrics. During pyrolysis, the finished fabrics apparently decomposed first by an acid catalyzed dehydration and chain breakdown. The second step of the pyrolysis probably involved phosphorylation of the C-6 hydroxyl of the anhydroglucose unit occurring around the temperature range of 345°–350°C. The final step was char formation. The THPOH-NH3 finished fabric decomposed with a strong exothermic reaction under nitrogen which suggested that the reaction was initiated by a base catalyzed dehydration and chain breakdown. This seemed to be followed by phosphorylation at the C-6 hydroxyl of the anhydroglucose units and then char formation. An inverse relationship between ΔH and the residue remaining after pyrolysis was observed. ΔH was also linearly related to the N/P ratios. All of the fabrics except the TPHC-cyanamide-finished fabric had good flammability properties before and after laundry.
