The specific heat of wool containing 2.6, 2.9, and 8.9 g. of water per 100 g. 01 dry wool has been measured over the temperature range −50 to 100°C. All of the wool samples showed an approximately linear increase of c p , with temperature, but small increments appeared at −30, 20, 50, and 70°C. With increasing water content at any one temperature the specific heat increased. The specific heat of the sorbed water seemed to be more nearly like that of ice than of liquid water; if the sorbed water is assumed to have the specific heat of ice a t all compositions and temperatures, an apparent specific heat of the wool can be calculated. With increasing water content the apparent specific heat of the wool approaches that of the synthetic polymer, nylon 6.
