大島紬の燃焼性の研究 : 燃焼熱と難燃機構 Flammability of Oshima-Tsumugi : Heat of Combustion and Mechanism of Flame-Retardation 〓 石橋, 博 イシバシ, ヒロシ 濱崎, 洋子 ハマサキ, ヨウコ ISHIBASHI, Hiroshi HAMASAKI, Yoko Flammability of the Oshima-Tsumugi fabrics has been studied by static oxygen bomb calorimetry. The amount of heat evolved when these fabrics are burned in the open atmosphere has been determined indirectly using calculations based on Hess' law of summation. The heat of combustion of the silk was reduced from 3870 cal/g to 2470～2830 cal/g by the mudmordanting. Fe salt as a mordant, combined with the silk in the mud mordanting, seems to be capable of catalyzing the silk decomposition and increasing the amount of char residue. Thus the effect of Fe salt is to decrease the amount of flammable gases produced by the pyrolyzing silk. Since the heat evolution is not sufficient to sustain the silk pyrolysis reaction, the mud-dyed Oshima-Tsumugi fabrics are high self-extinguishing. 4 KJ00000066189 1986-12-15 jpn departmental bulletin paper https://k-kentan.repo.nii.ac.jp/records/1267 AN00039943 37 9 14 https://k-kentan.repo.nii.ac.jp/record/1267/files/KJ00000066189.pdf application/pdf 326.6 kB 2016-07-25
