Measurement of The Dynamics of Fluid Sorption for Tissue Papers, 19PaperCon
Liquid absorption ability belongs to the most important features of tissue papers. Due to non-homogeneous internal and superficial structures, precise and fast evaluation of this property is not easy. The aim of the presented research was to design an experimental device able to characterize water absorption measurements of tissue papers. Hence, the system, named eXtended Liquid Penetration Analyzer (XLPA), was developed including both data acquisition and image analysis techniques.
Obtained results showed that our method based on image analysis supported by gravimetric methods, proved to efficiently and quantitatively characterize the dynamics of liquid absorption for tissue papers. Additional parameters such as absorption anisotropy and in-plane velocity were investigated. Different experimental results were obtained for various tissue paper grades. Furthermore, water absorption capacity calculated from image analysis data correlated with results obtained according to ISO 12625-8:2010 standard. Hence, the presented device characterizes and discriminates water absorption phenomenon for tissue papers.
