AbstractThe rate of acid hydrolysis of a basic dyeable polyester in water, before and after heat‐setting, has been investigated. Intrinsic viscosity measurements and chemical analysis have been used to establish experimental conditions under which the hydrolysis is inhibited. It is suggested that the critical stage of the hydrolysis mechanism is the exchange of sodium ions from the sulphonate groups in the fiber for hydrogen ion
