Abstract
This paper deals with radiation drying of woven and matted wool felts, of woven wool crepe, and of absorbent cotton batting. Radiant energy was supplied by R-40 electric lamps, and air conditions at the surface of the samples were controlled. Drying rate curves are analyzed in terms of drying mechanisms, and comparisons are made with convection drying by means of heated air. Among the variables discussed are air conditions, air velocity, intensity of radiant energy, sample thickness, optical properties of the materials being dried, and the initial regain.
