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

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

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

    Sammanfattning : 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. LÄS MER

  3. 2. Analys av textilproduktion och återvinning med fokus på miljöhållbarhet

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Sami Hagos; [2023]
    Nyckelord :Textile industry; sustainability; textile production; Synthetic; fibers; environment; circular economy; recycling; reuse; Textilindustri; hållbarhet; textilproduktion; Syntetiska; fibrer; miljö; cirkulär ekonomi; återvinning; återanvändning;

    Sammanfattning : Textilindustrin är en global växande resursintensiv industri som medför stora miljö och klimatförändringar. Den största delen av de negativa miljöeffekterna uppstår i samband med produktionen eftersom det vid produktion krävs stora mängder resurser och råvaror. LÄS MER

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

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Angus Hansson Svan; [2023]
    Nyckelord :Forecasting; Codeword Errors; Hybrid Fiber-Coaxial; Long Short-Term Memory; Multilayer Perceptron; Hybridfiber-koaxialt nätverk; HFC; LSTM; MLP;

    Sammanfattning : With an increasing demand for rapid high-capacity internet, the telecommunication industry is constantly driven to explore and develop new technologies to ensure stable and reliable networks. To provide a competitive internet service in this growing market, proactive detection and prevention of disturbances are key elements for an operator. LÄS MER

  5. 4. Impact of textile structure on mechanical recyclability

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

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

    Sammanfattning : 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. LÄS MER

  7. 5. 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

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :William Tönnberg; [2022]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
