Tissue paper consumption has been growing for the past years, with a forecasted increase in demand for premium products. Premium tissue paper products are obtained with a balance among softness, strength, and absorption properties, optimized for each kind of tissue paper. These properties are influenced by the three-dimensional structure, made from the spatial distribution of cellulose fibres. To our knowledge, the efforts made to date to improve the softness, strength and absorption properties have overlooked the 3D structure. There is an absence of 3D experimental data in the literature for the simultaneous characterization of individual eucalyptus fibres and the paper structure made from these fibres. The 2D fibre morphology determination, including fibre length and fibre width, was obtained by an image analysis method for pulp fibre suspensions, using the MorFi equipment. The third fibre dimension, the fibre thickness morphology in the out-of-plane direction, was obtained using SEM images of non-pressed isotropic laboratory-made paper sheets. The effective fibre thickness morphology, consisting of the fibre wall and lumen, was measured in the paper structure, as this is precisely the key fibre parameter, influencing not only the structure-related properties, such as paper thickness, bulk, and porosity, but also the final end-use properties. The paper structures were produced using an ISO standard adapted method, for tissue paper structures, without pressing, with a basis weight range from 20 to 150 g/m. These data are important, among other possible uses, for paper property optimization and simulation studies with 3D fibre based simulators.
在过去几年中，薄页纸的消费量一直在增长，预计对高档产品的需求也会增加。高档薄页纸产品是在柔软度、强度和吸收性能之间取得平衡而制成的，针对每种薄页纸进行了优化。这些性能受纤维素纤维空间分布所形成的三维结构影响。据我们所知，迄今为止为改善柔软度、强度和吸收性能所做的努力都忽略了三维结构。文献中缺乏用于同时表征单个桉木纤维和由这些纤维制成的纸张结构的三维实验数据。二维纤维形态测定，包括纤维长度和纤维宽度，是通过使用MorFi设备对纸浆纤维悬浮液进行图像分析的方法获得的。第三个纤维尺寸，即平面外方向的纤维厚度形态，是使用未压制的各向同性实验室制造纸张的扫描电子显微镜图像获得的。在纸张结构中测量了由纤维壁和腔组成的有效纤维厚度形态，因为这正是关键的纤维参数，不仅影响与结构相关的性能，如纸张厚度、松厚度和孔隙率，还影响最终的使用性能。纸张结构是使用一种适用于薄页纸结构的ISO标准方法生产的，不进行压制，定量范围为20至150克/平方米。这些数据除了其他可能的用途外，对于基于三维纤维的模拟器进行纸张性能优化和模拟研究也很重要。
