N2  - The oxidative decomposition of a green-and-white checkered cellulosic fabric, designated as FOR-1, comprised of four different yarns, was studied using TPR/GC and DSC techniques. Containing different alkali metal ion (AM(+)) and dye concentrations, these four yarns experienced directionally selective smolder behavior during cigarette ignition tests. Measurements were performed on the integrated fabric and on each of the four yarns. A model explaining the anisotropic smolder and high-temperature behavior of this fabric was developed. The decomposition of a heavily bleached, cellulosic sailcloth was also studied. The results showed an increase in the fabric degradation/cleavage rate compared to unbleached #6 cotton duck. The DSC spectra of the sailcloth, however, did not significantly differ from that of the washed cotton duck. Similar thermochemical behavior was observed in the blue-dyed denim fabric containing 1500 ppm potassium; the low-temperature DSC behavior of this denim was also found to be similar to that of undyed, nicotine-treated cotton duck studied in Reference [4]. These results support a model comprising the mechanisms of smolder and combustion of colored cellulosic fabrics.<p />
