- Abstract
- During the past few years there has been an increased interest in treatments that will reduce the flammability of cotton and rayon textiles. This is due in part to large losses of life such as in the Boston night club fire and the Hartford circus disaster from rapid combustion of the untreated material. There has also been a large military demand for flameproofed tentage, camouflage, and clothing fabrics. Although the developments in textile flameproofing extend back over 100 years, the recent demands have been met by some improvements in methods that render the treatments more effective and more resistive to wear, weather, and other conditions of use. The present Circular includes a review of the principles of flameproofing, a brief history of researches, formulas for various processes, and an outline of testing methods and requirements for the treated material. For the treated or intrinsically slow-burning materials a flame test with the fabric in vertical position is outlined. A method for determining the rate of burning in horizontal position is also defined, which is useful in indicating the relative flammability of untreated textiles.
