Whenever spills or contamination occurs in a cleanroom environment, staff must have access to appropriate cleaning tools. Mops fulfil an indispensable role in the management of contamination in controlled environments. The material from which a mophead is made and the way it is manufactured determine its characteristics concerning cleanliness (particles, ions, non-volatile residue, linting), strength (tensile strength, bursting strength, abrasion resistance), and functional characteristics (absorbency). An accurate comparison and the final selection of the mophead will to a significant extent determine whether the stringent conditions in the cleanroom will be met1. In this paper, we will look more closely at the various aspects of mophead’s absorbency. Only when there is sufficient insight into this parameter, a proper comparison and selection can be made.
