Abstract

An apparatus is described for measurement of vertical dimension of cotton samples immersed in water, methanol, tiquid ammonia, and NaOH solution. Increase in thickness of cotton showed recovery from compression and swelling. The increases were automatically recorded as a function of time by a chart recorder.

Keywords

Cotton swelling moisture regain. Thickness organic solvents compressibility. Apparatus measurement vertical expansion.
