1. 1. A PILOT STUDY ON STAIN REDUCTION Effects of Stains, Cleaning Agents, and Cleaning Methods on Polyester Textiles

   University essay from Göteborgs universitet/Institutionen för kulturvård

   Author : Karin Hindborg; [2023-08-28]
   Keywords : colour measurements; spot cleaning; suction table; tensile testing; textile con-servation;

   Abstract : The thesis was an experimental pilot study that investigated efficiency and effects of stains and cleaning agents on polyester textiles. A literature review and interviews with textile conservators were used to understand the degradation of polyester fibres and to find suit-able staining and cleaning agents to use in the experiments of the study.

3. 2. Thermal Conversion of Cellulose-Lignin Precursors into Carbon Fibres

   University essay from Uppsala universitet/Nanoteknologi och funktionella material

   Author : Sofia Westberg; [2023]
   Keywords : Carbon fiber; lignin; cellulose; continuous conversion;

   Abstract : Carbon fibres are used in many applications thanks to their exceptional tensile properties in relation to their relatively low weight. These thin strands of at least 90% carbon are mixed with a matrix such as epoxy to form composites used for cars, wind turbines, prosthetics, and many other things. READ MORE

4. 3. Quality enhancement of time-resolved computed tomography scans with cycleGAN

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Johannes Stubbe; [2023]
   Keywords : carbon fibers; carbon fibres; microfibers; tomography; deep learning; cycleGAN; time-resolved tomography; Physics and Astronomy;

   Abstract : Time-resolved x-ray tomography enables us to dynamically and non-destructively study the interior of a specimen. The obtainable temporal resolution is limited by the x-ray flux and the desired spatial resolution. READ MORE

5. 4. Modified cellulose synthesized by different deep eutectic solvents as an additive in paper making process

   University essay from Karlstads universitet

   Author : Shiniar Said Saleh; [2023]
   Keywords : green chemistry; dry strength additives; deep eutectic solvents; sodium periodate oxidation; charge density; dewatering; mechanical strength.;

   Abstract : The environmental concerns that come with the currently used traditional papermaking process where petroleum-based additives are used, has tempted researchers to study “green” additives by introducing environmentally friendly modifications of cellulose as an additive in the papermaking process. This thesis will spin further on that by producing additives with different charge densities and focus on to incorporate an etherification reaction into potentially greens systems based on non-toxic and readily biodegradable deep eutectic solvent (DES).

6. 5. The Influence of Pigment Additives on the Barrier Properties of Dispersion Coatings

   University essay from KTH/Fiber- och polymerteknologi

   Author : Malin Eriksson; [2022]
   Keywords : dispersion coating; paper products; pigment; sustainable development; circular economy; Dispersionsbarriär; pappersprodukter; pigment; hållbar utveckling; cirkulär ekonomi;

   Abstract : Att minska plastavfall och uppmuntra återvinning har fått hög prioritet i många affärsverksamheter och olika typer av regleringar implementeras för att minska den negativa påverkan av plastanvändningen. Papper och kartong består i huvudsak av cellulosa som har många egenskaper som är essentiella för en hållbar ekonomi (t.ex. READ MORE
