Procion‐dyed cotton that is insoluble in cuprammonium hydroxide may be rendered soluble by treating it in boiling 4% sodium carbonate solution, thus enabling its fluidity to be determined. By means of hot 40% aqueous hydrazine, all except one of twenty Procion dyes examined may be completely stripped from cotton without degrading it. Cloth stripped in this way is suitable for fluidity determinations and for re‐dyeing for testing purposes. Some of the experimental work was done by Miss V. A. Morris and Miss D. M. Wynne.
