Assessment of infrared radiation heat gain for selected fabric materials

Thermal manikin heating in response to a controlled Infrared radiation exposure was evaluated for fabric materials including wool, polyester, cotton, and polyurethane. The influence of separation spacers that were placed underneath the fabric was also studied. The results showed that all of the materials tested exhibited similar heating characteristics with no measurable attenuation of the infrared radiation. Overall, the fabric materials increased the manikin heat loading by an average of 22%. The data also revealed that the fabric materials contributed to additional heat loading by creating additional insulation. It was seen that the separation spacers did not improve the overall heat dissipation characteristics of the clothing materials. The results of this study identified key principles that should be considered when developing new clothing systems designed to protect persons against heat radiation.
