Hair fiber is a key by-product of humane slaughter of pigs with considerable
economic value. In the present study, we investigated the thermal properties
of pig hair fiber using Differential Scanning Calorimetry (DSC) and thermogravimetric
analysis (TGA). The DSC curve showed a broad endotherm(around
50–80°C) initially, followed by denaturation doublet peaks (229°C and 239°C)
and finally a pyrolysis endotherm. The melting enthalpy of pig hair fiber was
9.93 J/g on dry basis. During TGA, distinct phases of initial weight loss due to
loss of moisture and later through thermal degradation of protein around
238–240°C were observed. Mean thermal insulation and conductivity values of
pig hair fiber were 0.068 ± 0.004m2K/W and 0.029 ± 0.003 W/m/K, respectively.
The thermal characteristics of pig hair fiber were similar to other keratin fibers
of animal origin.
