Model of PTS The model approach of PTS is a further generalisation of the Multi-parameter model. It allows an in-depth analysis of fibre-flow systems of arbitrary complexity. Despite the fact that it is not possible to measure the fibre age by means of physical or chemical parameters until now, some researchers have made more detailed
