Abstract
The zeta potentials of wools treated by chlorination and by chlorine/Hercosett have been found to differ markedly. Fabrics made from the two wools and from a blend of the two were washed together at two values of pH. Under these conditions there is no evidence that surface charge effects make any contribution to felting shrinkage.
