What is: Wet-strength Papers ?

Ordinary papers often lose most of their dry strength properties once wet. Wet-strength paper's, however, possess certain properties that help them resist rupture and disintegration when saturated with water. When papers retain fifteen percent of their dry tensile strength, they are classified as wet-strength. Wet-strength paper's that retain about fifty percent of their dry tensile strength after being immersed in water are known as superior quality wet-strength papers.
