  1. 1. A PILOT STUDY ON STAIN REDUCTION Effects of Stains, Cleaning Agents, and Cleaning Methods on Polyester Textiles

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Karin Hindborg; [2023-08-28]
    Nyckelord :colour measurements; spot cleaning; suction table; tensile testing; textile con-servation;

    Sammanfattning : The thesis was an experimental pilot study that investigated efficiency and effects of stains and cleaning agents on polyester textiles. A literature review and interviews with textile conservators were used to understand the degradation of polyester fibres and to find suit-able staining and cleaning agents to use in the experiments of the study.

  3. 2. Thermal Conversion of Cellulose-Lignin Precursors into Carbon Fibres

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Sofia Westberg; [2023]
    Nyckelord :Carbon fiber; lignin; cellulose; continuous conversion;

    Sammanfattning : Carbon fibres are used in many applications thanks to their exceptional tensile properties in relation to their relatively low weight. These thin strands of at least 90% carbon are mixed with a matrix such as epoxy to form composites used for cars, wind turbines, prosthetics, and many other things. LÄS MER

  4. 3. 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

  5. 4. Material av restprodukter från hampa till produktdesign

    Kandidat-uppsats, Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

    Författare :Daniel Gezavati; [2023]
    Nyckelord :Industrial Design; Sustainability; Hemp; Material Innovation; By-products; Upcycling; Industridesign; Hållbarhet; Hampa; Restprodukter;

    Sammanfattning : This paper is a research through design that answers the question: How can the by-products from hemp production be utilized to create a sustainable material for product design?Hemp is the commercial crop that sequesters carbon dioxide most effectively in the world, but large amounts of bast fibers and hurd emerge as by-products ater cultivation for seeds, flowers, and leaves. These by-products can be difficult for farmers to manage as they require space for storage and often must undergo a lengthy production process before they can be converted into products. LÄS MER

  7. 5. 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
