The author has studied the influences of Wα, viz., those of the water of imbibition which causes Wα, upon the physical properties of papers by comparing the sheets made from W-state stuffs with those from Wm-state ones, the differences observed being due to Wα according to the equation W-Wm=Wα. The results have been as follows : -
The water of imbibition in stuffs increases the bursting strength, the transparency and the self-sizing degree, and decreases the absorbency and the thickness of paper sheets made from them. Thus it has, for the first time, been asserted experimentally that the water of imbibition or the so-called hydration water adds strength to paper.
