Abstract
Tests for the adsorption of water vapor by collagen, commercial hide powder and commercial leathers indicate that purified collagen has higher affinity for water than does hide powder, showing that the previous chemical treatment influences adsorption. Tanning does not decrease water-vapor adsorption at relative humidities below 70%. The effect of high temps. on moisture adsorption is studied by subjecting specimens to elevated temps. and then determining the adsorption at 28[degree]C. The changes of water adsorption with temp. can be expressed by a simple relation involving the log of the water adsorbed and the inverse of the absolute temp.This publication has 6 references indexed in Scilit:
