Technical BulletinPaperMoisture and Relative HumidityIssue 2005 2 The major component of paper, cellulose fiber, ishygroscopic in nature. A material that is hygroscopicwill absorb Moisture from a damp atmosphere orrelease Moisture to a dry atmosphere and, after sufficient exposure time, will come into equilibrium(balance) with its atmospheric paper encountered in normal situations containssome Moisture since it is composed of cellulosefibers. This normal Moisture content will generallyrange between 2% and 10% depending on the typeof paper, its past Moisture history and the atmos-pheric conditions to which it is exposed.
Technical Bulletin 2 As the temperature of the air increases, its ability to hold moisture increases. Air, when heated, will retain the same absolute humidity, but its relative humidity
