Abstract

The effect of papermaking variables on the structure and transport properties of paper samples was analyzed Various newsprint samples were prepared on a pilot paper machine by varying the raw material furnish and process parameters, including headbox consistency, retention aids and calendering. Three-dimensional digital images of the sample structure were obtained by using the synchrotron X-ray computed tomography facility at ESRF, Grenoble, France. Structural parameters (porosity, specific surface area, pore-size distribution and tortuosity) and transport properties (permeability and diffusivity) were calculated directly on the digitized images. Results indicate that the calendering operation plays a dominant role in altering the structure and transport properties of the samples.
