| Abstract: | This study presents thermal
degradation and burning behaviour of cellulose based and cellulose-silk blended
upholstery fabrics treated with phosphorus (chemical A) and halogen (chemical B)
based flame retardant (FR) chemicals. Char content increased substantially in
all samples after treatments. Calculated activation energy (Ea) was found as follows: control cotton(CP), 196.5; cotton+flax (CF), 213.3;
and cotton+silk (CS), 254.6 kJ/mol. Calculated Ea after treatment with chemical A
and chemical B, respectively, was reduced to: CP, 38.2, 130.6; CF, 96.2, 151.3;
and CS, 97.7, 152.0 kJ/mol. Char length, after glow and rate of flame spread, were
changed significantly after chemical was applied onto samples. Effect of FR
reduced after treated fabrics were washed for 3 repeated cycles; rate of flame
spread and char length were significantly lower when compared to control
samples. Thus impregnation of FR on cellulose and silk made them force out
water vapour under initial burning condition and thereby resisted burning. |
