- Abstract
- A radiometric method for measuring surface temperatures which may change as rapidly as 200 deg C per second has been developed and successfully applied to textile fabrics exposed to intense thermal radiation. The pyrometer was calibrated by means of a technique utilizing the boiling points of selected pure substances. Temperature-time curves are given for cotton, rayon, wool, nylon, terylene, and orlon fabrics. Prominent features of these curves are related either to evaporation of contained moisture or to melting of the fiber. The fibers examined, with the possible exception of wool, show approximately the same emissivity in the spectral range from 3.5 to 7 microns.
