It is shown that chloroamines can oxidize wool by two different mechanisms, although in neither case does reaction occur via the intermediary of free chlorine in solution. Only one of the reactions renders wool non‐felting, and it is favoured by the presence of chloride ions in solution and by increasing the electronegativity of the group adjacent to the reactive > NCI group. Amino acid analyses of treated wool and reaction with model substances show that the disulphide bond is equally readily oxidized by both mechanisms, although they differ in their reaction with tyrosine, which, it is suggested, must be oxidized for the production of non‐felting wool by surface degradation.
