  1. 1. Life Cycle Assessment : a comparison of fossil energy use and climate impact on small scale manufacturing and large scale conventional manufacturing of textile toys

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Energy and Technology

    Författare :Malin Henriksen; [2024]
    Nyckelord :textile toy; LCA; energy use; sustainable production; China; Sri Lanka; cotton production; fossil fuel use; GWP100;

    Sammanfattning : This study conducts a Life Cycle Assessment to compare the environmental impacts, specifically climate impact and fossil fuel use, of textile toys produced in China and Sri Lanka. Through evaluating large-scale industrial production in China against small-scale, handcrafted production in Sri Lanka, it identifies the considerable environmental footprint of cotton production in both scenarios.

  3. 2. Investigation on the natural indigo dye for cotton fabric by using supercritical carbon dioxide

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

    Författare :Ryoi Takamatsu; [2023]
    Nyckelord :Dyeing; supercritical carbon dioxide; indigo; cotton; eco-friendly; textile;

    Sammanfattning : Concerns about the environmental impact of the textile industry are increasing, and there is an urgent need to develop and implement sustainable technologies. In particular, the environmental impact of dyeing, which emits a large amount of wastewater and chemicals, is one production process that needs to be resolved. LÄS MER

  4. 3. Impact of Organic Solvent Treatments on Physical and Sensorial Properties of Knitted Fabrics.

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

    Författare :Sara Isabel Zamora Lagos; [2023]
    Nyckelord :Innovation; Screen-printing; Knitted fabric; Polyester; Cotton; Organic Solvents; Cycle; Properties; Physical; Structure; Sensorial.;

    Sammanfattning : Technologies that facilitate reusing and recycling printed textile products will contribute to achieving a circular textile industry. This project was done in collaboration with Vividye, a company developing a technology to create removable textile prints to be able to extend the lifespan of screen-printed textile products without affecting their quality.

  5. 4. Study on Decolorization of Reactive-dyed Cotton through Fenton-oxidation as a Pre-treatment for Textile Recycling

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

    Författare :Elise Meurs; [2023]
    Nyckelord :Fenton-oxidation; advanced oxidation processes; decolorization; textile recycling; cotton; reactive dye;

    Sammanfattning : In this master thesis, the feasibility of Fenton-oxidation for the decolorization of reactive dyed cotton is investigated as a potentially environmental-friendly preparatory treatment for mechanical/chemical recycling. Raw, knitted cotton is dyed with a black and a blue dye, whereafter preliminary tests are performed to investigate the influence of increasing Fenton- solution concentrations and different iron-sources on the efficiency of the discoloration, without carrying out complete optimization of the process-parameters.

  7. 5. 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
