Use of cyclic differential scanning calorimetry

Combustion processes of textile fibres

“…Thus the decomposition of cellulose has been extensively studied (Faroq et al ., 1991 ;Price et al ., 1993 ). Whilst other more detailed mechanisms have appeared in the literature (Price et al ., 1997 ), the basic processes proposed are all in line with that fi rst suggested by Bradbury et al .…”

Cotton flame retardancy: state of the art and future perspectives

“…To this aim, some model molecules have been used, as well. The main concepts regarding the mechanisms, through which cotton degrades and thus burns have been clearly understood in this period, thanks to the comprehensive work carried out by Shazadeh and coworkers, 6,7,16,[29][30][31][32][33] Horrocks alone or in collaboration with Price and Kandola 4,14,17,[38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55] and the new analytical techniques employed by Morterra 56-63 and Emsley. The former group is typied by Proban® (Rhodia) product which is based on tetrakis(hydroxymethyl) phosphonium-urea condensate: aer padding onto cloth, it is cross-linked by ammonia gas and followed by peroxide oxidation to stabilise the resulting polymeric matrix.…”

Polymer Degradation and the Matching of FR Chemistry to Degradation

“…Whilst there is controversey as to whether or not this Cellulose * species exists or not, experimental evidence for the Cellulose * species was obtained by Price et al [49] who suggested it could be free radical in nature. At lower temperatures, oxygen plays a dominant role is cellulose degradation, pyrolysis is faster in an oxidative atmosphere than in an inert one [50] Oxygen catalyses the formation of both volatiles and char promoting reactions [51] At higher temperatures, the degradation products are little affected [50].…”
