The preparation of tritium‐labelled formaldehyde and its use for the autoradiographio determination of the distribution of urea‐formaldehyde resin finish in textiles are described. The resin is found to be uniformly distributed in any filament cross‐section with no resin layer on the surfaces, except in certain unusual cases. The distribution of resin across fabric sections is consistent with migration occurring during drying to those regions where drying is the most rapid. The results of some unusual methods of treatment are given. Resin distribution in a blended fabric has been determined. The autoradiographic method and a staining method for the determination of resin distribution have been compared.
