  1. 1. Risk assessment of non-intentionally added substances in polyester yarn made from recycled polyethylene terephthalate (PET)

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Kristina Arnqvist; [2023]
    Nyckelord :r-PET; polyester yarn; NIAS; risk assessment;

    Sammanfattning : Polyester is a synthetic material made from polyethylene terephthalate (PET), which is synthesised from fossil raw materials. Many clothing manufacturers are using polyester in their clothing, which, from an environmental perspective, creates a non-sustainable cycle. LÄS MER

  3. 2. CSR communication and the use of recycled synthetic fibres in the fashion industry: A content analysis study of two Swedish fashion brands

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Linn Löfling; [2023]
    Nyckelord :recycled synthetic fibres; fast fashion; slow fashion; CSR communication; Earth and Environmental Sciences;

    Sammanfattning : The fashion industry is one of the largest contributors to environmental issues and has a significant part of plastic production due to the use of synthetic fibres. Much scientific research indicates that the fast fashion model is a significant part of using synthetic fibres; however, slow fashion brands are also using the fibres. 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. Sustainable Polymer Production: Investigating Synthesis and Copolymerization of Cyclic Ketene Acetals

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Soufian Bourraman; Stella Staffas; Adam Brandt; Simon Isaksson; [2023]
    Nyckelord :Monomers; polymers; radical; radical ring opening polymerization; polymerization; BMDO; MMA; MVL; MBL; comonomer; copolymer; rROP; sustainable; biobased; degradable; monomer synthesis; plastic; polyester; bulk; solution; NMR; FTIR; TGA; DSC; SEC; hydrolysis; molecular weight; diol; ester bonds;

    Sammanfattning : The large amount of non-degradable plastic waste has become a significant environmental concern, leading to an increased need for degradable plastics. Here in, to create degradable polymers, polyesters were produced through radical ring opening polymerization using cyclic ketene acetals. LÄS MER

  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
