  1. 1. Techno-Economic Analysis of Dye Separation in Textile Recycling

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : David Lundberg; [2024]
    Keywords : Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

    Abstract : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. READ MORE

  3. 2. Forecasting Codeword Errors in Networks with Machine Learning

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

  4. 3. Impact of textile structure on mechanical recyclability

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Linnéa Bengtsson Creaser; [2023]
    Keywords : Textile recycling; mechanical recycling; textile tearing; fiber length; recyclability;

    Abstract : This thesis investigates the impact of yarn and fabric structure on the mechanical recyclability of textile structures. It focuses on variations in yarn twist and form (single or plied) as well as fabric type (woven or knitted) and their respective constructions. READ MORE

  5. 4. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : William Tönnberg; [2022]
    Keywords : Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

    Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE

  6. 5. Archaeogenomics illuminates 4000 years of Northern European Short Tailed Sheep in the Baltic Sea region

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Martin Larsson; [2022]
    Keywords : Sheep; Archaeogenomics; ancient DNA; Northern european short tailed sheep;

    Abstract : Sheep were domesticated ~10 000 years ago from Asiatic Mouflon. They then spread to Europe via the migration of farming human populations and had reached Scandinavia by ~6000 years ago. Another migration of humans stemming from the Pontic-Caspian steppe reached Scandinavia around ~5000 years ago, possibly with new types of sheep. READ MORE
