Abstract

This study was to investigate the thermal insulation of clothing ensembles, including padded jackets with two different filling types. Thermal insulation of the ensemble was measured using a thermal manikin in four conditions (10℃, 30% RH and 20℃, 50% RH with an air velocity of less than 0.15 m·s-1 and 1.5 m·s-1). Ten males participated at 10℃ and 30% RH with an air velocity of less than 0.15 m·s-1 and 1.5 m·s-1. The results showed that the polyester ensemble was warmer than a goose down ensemble in 0.15 m·s-1 conditions and the goose down ensemble had greater thermal insulation than the polyester ensemble at an air velocity of 1.5 m·s-1. Thermal insulation was reduced 5-7% when temperature decreased 10℃ and reduced 40-50% when air velocity reached 1.5 m·s-1 for both ensembles. Thermal insulation of the ensemble in human trials decreased more than a thermal manikin at 10℃, 30% RH with an air velocity of 1.5 m·s-1. Lower temperatures and human trials were effective in identifying the properties of the thermal insulation by filling types even though there were restrictions on the general application because of two types of a clothing ensemble.
