The presence of a wetting agent (Igepon) accelerated only the initial degradation of a raw cotton exposed to 0.1 N hydrochloric acid at 20°C in the absence of light for periods of up to 350 days. During this time the dry strength decreased by almost one- half. The dry strength decrease, being slightly greater than the wet strength decrease, resulted in a small relative wet strength increase, from 93% to 110%. Purified cotton- linters were degraded more slowly than raw cotton, and an alkaline refined sprucewood pulp more slowly still, even though the wetting agent was present in the latter case.
