Evaluating the resistance of some protective fabrics to molten iron.
Tex Res J 1981 Aug; 51(8):533-541
The behavior of 22 different protective fabrics in resisting heat transfer and thermal disintegration on impact with molten iron (7439896) was investigated. Molten iron was poured onto the fabric from a fixed height and angle of incidence and heat flow through the fabric was measured by an instrumented copper calorimeter located near the impact point. The amount and character of damage to the fabric was subjectively evaluated. There were significant differences in the capacity of various fabrics to resist heat transfer with maximum heat flux values ranging from about 10.5 watts per square centimeter in the case of modacrylic fabric to less than aluminized fabrics deflected the heat particularly well and were judged to be least damaged following impact with the molten iron. The authors suggest that the performance of a fabric in a controlled splash test is related to measurable properties such as the fabric's weight or thickness, air permeability, and flammability.
