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

    University essay from Göteborgs universitet/Institutionen för kulturvård

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

    Abstract : 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

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Sofia Westberg; [2023]
    Keywords : Carbon fiber; lignin; cellulose; continuous conversion;

    Abstract : 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. READ MORE

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

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Kristina Arnqvist; [2023]
    Keywords : r-PET; polyester yarn; NIAS; risk assessment;

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

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

    Abstract : 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. READ MORE

  6. 5. Quality enhancement of time-resolved computed tomography scans with cycleGAN

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Johannes Stubbe; [2023]
    Keywords : carbon fibers; carbon fibres; microfibers; tomography; deep learning; cycleGAN; time-resolved tomography; Physics and Astronomy;

    Abstract : Time-resolved x-ray tomography enables us to dynamically and non-destructively study the interior of a specimen. The obtainable temporal resolution is limited by the x-ray flux and the desired spatial resolution. READ MORE
