An examination of the Cu (II)/wool esr signal intensity variations, together with other relevant copper (II) uptake data, have shown that two types of products are formed during the Cu (II)/wool interaction. One of these gives rise to the observed esr signal, while the other is a diamagnetic sulfide of copper. The latter product arises as a result of a reaction of the metal ion and the products of a water/wool interaction. A reaction scheme consistent with the experi mental observations is suggested.
