Abstract

A novel handsheet multilayering technology has been developed to produce layered paper sheet samples. The basic idea of the multilayer sheet former is to create a layered sheet structure between two fabrics, in the same way that a sheet is created in a gap former. Using the sheet former's layered sheet process, the potential effects of layering can be studied. The described method of two sided, relatively slow, water removal achieves excellent layer purity as well as good layer coverage. A number of experiments have been done to study and observe the potential of using this method to create layered paper test samples. As a part of multilayered sheet studies, the effect of retention chemicals and filler layering on final paper filler distributions has also been studied. Further, handsheet layering has also been utilized in studies of fiber migration within a layered sheet using dyed fibers.
