For unsized papers such as blotting papers and other papers having relatively high water absorbency the Klemm method for determining water absorbency is used. Test pieces are
immersed to a set depth in water
and the height of the water rise is measure after a set time. Smithers test in accordance with BS 6504.

contact time, sheet size, liquid type, liquid temperature, surrounding temperature and humidity, and many others
.
Which paper towel absorbs the most liquid?
