  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. Optimering av en hydraulisk sprayfärgningsprocess med hjälp av förbehandlingar

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

    Författare :Asta Ovander; Saga Hallberg; [2023]
    Nyckelord :Hydraulic spray dyeing; wool dyeing; plasma technology; ultrasonic bath; sustainable preparation; resource efficient; Hydraulisk sprayfärgning; ullfärgning; plasmateknologi; ultraljudsbad; hållbar beredning; resurseffektiv;

    Sammanfattning : Textilindustrin har under de senaste åren vidtagit drastiska åtgärder för att ställa om till en mer hållbar industri och därav möta målen för Agenda 2030. Denna undersökning syftar till att förbättra den resurssnåla hydrauliska sprayteknikens infärgning på ullvävar med hjälp av två resurssnåla förbehandlingar, plasmateknologi och ultraljudsbad.

  4. 3. Influence of supercritical carbon dioxide (scco2) dyeing parameters on color fastness of polyester fabric dyed with disperse dye : A study towards minimizing the energy consumption of polyester (pet) fabric dyeing with azo disperse dye

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

    Författare :Tapas Das; [2023]
    Nyckelord :Supercritical fluid dyeing; polyester PET fabric; coranger orange PE3330; color fastness; ideal dyeing conditions; eco-friendly;

    Sammanfattning : Amid growing environmental concern and continuous depletion of natural resources (such as water), the textile industry is constantly searching for sustainable production process. Traditional dyeing processes, notorious for their enormous water consumption, have led society to search alternative dyeing method. LÄS MER

  5. 4. Sustainable textile management and business practices among small scale fashion brands in Indonesia

    Master-uppsats, Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi; Lunds universitet/LUMID International Master programme in applied International Development and Management

    Författare :Maria Yartseva; [2023]
    Nyckelord :Social Sciences;

    Sammanfattning : The current fashion and textile industry is one of the largest contributors to climate change and environmental degradation. The industry uses toxic dyes and chemicals to cultivate, manufacturing and processing stages. LÄS MER

  7. 5. Quantitative and qualitative analysis of dyes in pulp from recycled textiles

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Anna Bevin; [2023]
    Nyckelord :Textile fibers; Dyes; Kappa number; FTIR; UV-VIS; Textilfibrer; Färgämnen; Kappatal; FTIR; UV-VIS;

    Sammanfattning : To decrease the environmental footprint, the textile industry needs to become more circular. One company that is trying to close the textile lifecycle loop is the Swedish company Renewcell. In the Renewcell process, discarded clothes and other textile waste are turned into a dissolving pulp that can be used for production of new textiles. LÄS MER
