wet-strength paper
A paper which, even when saturated with water, has
an unusually high resistance to rupture or
disintegration. This property is produced by
subjecting the paper or the fibers from which the
paper is made to chemical treatment. Wet strength.
which is most evident and significant when it
occurs in absorbent papers. should not be confused
with water repellency or the resistance of paper
to wetting when exposed to water. Normally, a
paper loses most of its strength when saturated
with water, and one which retains more than 15% of
its dry strength when completely saturated with
water may correctly be referred to as a
"wet-strength paper." A very superior wet-strength
paper may retain as much as 60% of its dry
strength when wet. (17 , 42 )
