초록

The purpose of this study was to analyze the effect of fiber type, compressional resilience and moisture transport properties of wool and polyester fiber on the heat transfer of insulation nonwovens. The results obtained were as follows: 1) Overall heat transfer of wool nonwoven was slightly higher than that of polyester nonwovens. Warmability of wool nonwoven was lower than that of polyester nonwovens. The radiative heat transfer was in the range of 11~18% of overall heat transfer in polyester nonwovens and 25% in wool nonwoven. 2) As wool nonwoven compressed, overall heat transfer was increased by increasing radiative heat transfer and wamability was decreased due to the poor compressional resilience. 3) Increasing rate of heat transfer by moisture absorption in wool nonwoven was lower than that of polyester nonwovens. Thickness and compressional resilience of wool nonwoven were reduced extremely by moisture absorption.
