THE INFLUENCES OF THE WATER OF IMBIBITION UPON THE PHYSICAL PROPERTIES OF THE PAPER.

STUDIES ON THE BEATING OF THE PULP. XIII.

Abstract

The author has studied the influences of W_α, viz., those of the water of imbibition which causes W_α, upon the physical properties of papers by comparing the sheets made from W-state stuffs with those from W_m-state ones, the differences observed being due to W_α according to the equation W-W_m=W_α. 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.
