15.2 Improving BCTMP Tissue Paper Properties by Combining Pulp Fractionation, Surface Quaternization of Fines and Stratified Forming
Bleached chemi-thermomechanical pulp (BCTMP) is an energy-efficient and environmentally friendly alternative to traditional chemical pulps, offering a higher yield from raw wood fibers and reduced chemical usage. Additionally, BCTMP provides cost advantages by requiring less material to produce the same volume of paper. This study explores the potential of using BCTMP for tissue paper manufacturing […]
15.1 Micromechanics Modeling of Pulp Fibers and Validation with Single Fiber Tensile Experiments
Climate change concerns have spurred research into natural fiber composites (NFCs), which offer advantages over synthetic ones, such as lower environmental impact and cost [1]. The lumber industry generates significant by-products, often thermally processed, leading to CO2 emissions. Utilizing these by-products can reduce the environmental impact and increase the economic value of wood processing. Their […]
15.3 Combining Small- and Wide-Angle X-ray Scattering with Dynamic Mechanical Analysis to Study Moisture-Driven Material Behavior
Understanding moisture’s impact on materials’ mechanical properties is crucial for both fundamental research and practical applications. In this work, we introduce an integrated experimental approach that combines dynamic mechanical analysis (DMA) under controlled humidity and temperature with simultaneous small- and wide-angle X-ray scattering (SWAXS). This setup leverages high-brilliance X-rays from the MAX IV synchrotron (Lund, […]
P15.1 – Influence of Nanocellulose and hybrid morphologies on Taylor-Couette flow instabilities
We examine non-Newtonian effects in supercritical flow between independently rotating concentric cylinders of nanostructured self-assembling systems. Instabilities in the flow between rotating concentric cylinders, known as Taylor Couette flow, have been a benchmark for stability analysis. For non-Newtonian fluids, a significant amount of research has been dedicated to identifying the roles of elasticity and shear-thinning […]
P15.2 – Impact of Thermal Treatment on the Mechanical and Structural Properties of Nanocellulose Filaments
The outstanding mechanical properties of cellulose have long motivated us to use it as a sustainable source to improve the mechanical properties of materials. After isolating cellulose from wood pulp and defibrillating it into nanocellulose, the reported mechanical stiffness ranges between 110-150 GPa.[1, 2] Since 2014, a spinning process utilising a flow-focusing microfluidic device that […]
