Summary Measurements are made of the resistance to wet abrasion of patterns of light‐weight flannel which have been treated at various temperatures with buffered solutions of p H 1–12. The results show that the degree of modification increases with rise of temperature, and at a fixed temperature the reduction in resistance to abrasion depends on the p H of the liquid with which the cloth has been treated, being a minimum in the region of p H 4–7. The presence of residual acid or alkali reduces the resistance of fabries to wet abrasion. The degree of modification produced by blowing at various p H values increases with increasing acidity or alkalinity, outside the region p H 5–7. Whenever possible, processing should be carried out at p H 5–7.
