The development of biocompatible polymeric biomaterials, considering the structural hierarchy at the fiber and structure levels through 3D computational simulation is an example of multidisciplinary research in the field of materials science and engineering. The design of biomaterials, such as tissue products, involves the optimization of the 3D network structure and porosity to obtain high liquid retention and improve functional properties. High-quality tissue paper fibrous materials require the use of several types of fibers, fiber modification processes, and additives incorporation [1-4]. In this work, we present an innovative strategy aiming the optimization of water retention in structures produced with different furnish formulations, and industrial tissue papers. Laboratory structures with basis weight between 20 and 60 g/m2 were produced with different eucalyptus fibers, fiber mixtures containing eucalyptus and softwood fibers in different percentages, enzymatic treatments applied to eucalyptus fibers suspensions, and micro/ nanofibrillated cellulose incorporation, as an additive. Furthermore, industrial market tissue paper products, including napkins, towel papers, and toilet papers, were also selected. A combination of water absorption capacity, Klemm capillary rise, and liquid droplet spreading kinetics properties was performed. The results indicated that this methodology approach was able to quantify the influence of liquid retention properties for the different formulations, as well as commercial tissue papers [5-6]. These data were integrated with an innovative simulator for tissue papers that establishes relationships between the fiber properties, the fiber modification processes, and the key properties of tissue papers. In conclusion, a strategy of design, engineering, and simulation of tissue paper materials was performed to support the furnish management that includes the changes in fibrous composition, fiber modification strategies, and micro and nano-scale additives incorporation, aiming the improvement and optimization of the final end-use tissue properties [7-8].
