Wet -

As fibers absorb water and expand unevenly, the paper buckles, creating a wrinkled, uneven surface, a process known as cockling.

When paper gets wet, its physical and optical properties change significantly due to the behavior of its cellulose fibers, which are normally held together by hydrogen bonds. As fibers absorb water and expand unevenly, the

Once wet paper dries, it rarely returns to its original flat state because the bonds reform in new, irregular positions. Techniques for Handling Wet Paper the paper buckles

Wet paper becomes translucent or see-through because water fills the air gaps between fibers, reducing light scattering. creating a wrinkled

Water competes with the fiber-to-fiber hydrogen bonds, causing them to break and making the paper soft and fragile.
