The Cobb value of surface water absorption of paper and paperboard.:
The calculated mass of water absorbed in a specified time by a unit area of paper or board under specified pressure and temperature conditions. It is expressed in g/㎡.
C=(G2-G1)×100.
C-water absorptiveness
G2-wet mass, in grams, of the test piece
G1-dry mass, in grams, of the test piece
