- Abstract
- Single and double layers of fabrics were exposed to a radiative heat flux of 0.84 W/cm2 for 2 minutes. The time to burn injury and the total heat transferred through the fabric to a heat sensor were measured. When the fabric layers were in contact with each other and with the sensor (a "worst case" situation resembling "real life" heat texposure when garments are under tension), the insulative values were, in the first approximation, related to fabric weight. Introduction of space between the fabrics and between the inner fabric and the sensor greatly increased the insulative value.
