Photosensitive adsorption of water vapour on wool

The adsorption of water vapour on wool at atmospheric pressure of air at 5 to 20% relative humidity, has been shown to be influenced by the action of light, the effect of irradiation being to increase the moisture content. The magnitude of the change is of the order of 0·3‐0·5% increase on a moistur...

Description
Summary:The adsorption of water vapour on wool at atmospheric pressure of air at 5 to 20% relative humidity, has been shown to be influenced by the action of light, the effect of irradiation being to increase the moisture content. The magnitude of the change is of the order of 0·3‐0·5% increase on a moisture content of 5% at 12% relative humidity at 20°. The effect, which has been observed at both 20° and 35°, is rapid and reversible. The phenomenon has not so far been observed with a synthetic vegetable protein fibre.
