The durability of wool/polymer adhesive Joints in wash liquors of different surface tension was determined by measuring the rate of felting shrinkage of polymer-treated wool sliver and fabric in each liquor. The rate of felting shrinkage increased as the surface tension of the liquor decreased. This trend in the rate of felting shrinkage of polymer-treated wool agreed well with the trend in the magnitude of the thermodynamic work of adhesion of a wool/polymer “adhint” in different liquids, calculated assuming only secondary bonding forces across the wool/polymer interface. Limitations of the theory are discussed
