A study of pyrolysis and pyrolysis products of flame-retardant cotton fabrics by DSC, TGA, and PY–GC–MS

“…The first type is a combustion of flammable gases and volatile liquids; the solid state burning is an oxidation of solid residues (mainly carbon). The temperature of the flame burning is lower than that of the solid state burning [12]. The later would cause more thermal decomposition (pyrolysis) of the materials.…”

“…Thermal decomposition of cellulose produces many flammable fragments, including compounds such as aldehydes, ketones, furans, furfural, and mucleoglucosan reported by other researchers [10][11][12][13]. Literature reported PY-GC-MS of cotton fibers showed more than 40 chromatographic peaks including over 20 kinds of thermally decomposition products [10].…”

“…With the development of instrumental analyzing methods, especially applications of pyrolysis-gas chromatography-mass spectroscopy (PY-GC-MS), researchers can study pyrolysis and pyrolysis products of flame-retardant textile materials in detail [7][8][9][10][11][12][13][14]. The pyrolysis of cotton plays a key role in affecting flammability of the polymer, thus pyrolysis products of flame-retardant and control fabric should provide valuable information on flameretardant mechanism of cellulose with the flame-retardant.…”

“…The pyrolysis of cotton plays a key role in affecting flammability of the polymer, thus pyrolysis products of flame-retardant and control fabric should provide valuable information on flameretardant mechanism of cellulose with the flame-retardant. Pyrolysis of cellulose fibers has been investigated elsewhere [5][6][7][8][9][10][11][12][13][14], however, less work was done on flame-retardant treated cellulose, though development of flame-retardants and flame-retardant finishing technology has been achieved. In this study the DSC and TGA thermograms of flame-retardant and control fabrics, together with PY-GC-MS analyses were employed to study the pyrolysis process and products of the fabrics.…”

Characterization of Methyl Methacrylate Grafting onto Preirradiated Biodegradable Lignocellulose Fiber by γ‐Radiation

“…A large endotherm between 328 and 375 8C, with a peak maximum at 355 8C, represents the complete loss of the OH groups of the monomer units of cellulose and depolymerization and volatilization of cellulose, followed by exothermic decomposition of degraded products. [25][26][27] The large but broad exothermic peak between 431 and 585 8C with a maximum at 494.7 8C is attributed to the decomposition of lignin. In the case of grafted jute with 13.6% graft weight, we found a broad endothermic peak between 314 and 385 8C, with a peak minimum at 359 8C (Figure 8b), which was assigned to the depolymerization of cellulose-graft-PMMA.…”
