Abstract

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