WebGurley porosity is an expression of air flow rate. Expressed as the time taken for a certain volume of air to pass through a specific filter area under a certain pressure. WebThe porosity of a paper is a function of the various stages of the papermaking process. An increased level of fiber refining causes the fibers to bond together more strongly and tightly, making the paper denser, and reducing the network of air passages and thus the porosity. Surface sizing, coating, calendering and supercalendering all also ...
