Autoradiographs have been made of cross‐sections of several different kinds of viscose rayon filament after finishing with tritiated urea‐formaldehyde resin. The skin of Tenasco is shown to contain less resin than the core, and in a fabric containing both Durafil and Fibro filaments the latter thin‐skin filaments contain more resin than the former all‐skin ones. An interesting resin distribution has been obtained in crimped staple; the lobes enveloped in thin skin contain more resin than the main thick‐skinned portions.
