We already know that the ply of a napkin affects its absorbency, which ultimately determines how effective it is. But let’s dig even deeper to discover the chemistry behind the lowly napkin:
Molecular Napkin Science: Absorbency

Paper napkins are made of cellulose fibers. Cellulose is an organic compound that forms long, linked chains.
The hydrogen (H) atoms in water (H2O) form temporary bonds with the oxygen (O) atoms in cellulose.
These temporary bonds are called hydrogen bonds and they pull water molecules up and trap them between cellulose sheets.
Higher ply = more absorbency = fewer napkins needed!
