The reaction of wool with ethyl, octadecyl, phenyl, and α-naphthyl isocyanates under anhydrous conditions is described. At low uptakes these reagents confer marked re sistance toward solubilization in hot acid; increasing uptakes reduce the felting shrink age and impart stability to degradation by alkali and oxidizing and reducing agents.
