This research focuses on evaluation of nonwoven fabrics used as padding for thermal insulation clothing. The thermal insulation of textile fabrics depends on properties like thermal conductivity, thermal resistance, thermal diffusivity, thermal absorptivity, thermal effusivity, density and thickness. Experiments were conducted with an objective of studying heat transfer by conduction through the different thickness of fabrics used as thermal insulators especially at temperatures below 0°C. The nonwoven padding fabrics with different composition of polypropylene/polytetrafluoroethylene and 100% polypropylene were used in this work. Alambeta and C-Therm Thermal conductivity analyzer (TCi) have been used to measure the thermal properties. The relationship between the thermal conductivity, thermal resistance, thermal absorptivity, thermal diffusivity and thermal effusivity with fabric density of the selected fabrics were studied. It was observed that fabric density and thickness had a significant effect on the thermal properties. [ABSTRACT FROM AUTHOR] |
