  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. Möjligheterna för återvinning eller återanvändning av kaseinfekterad betong

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

    Författare :Merve Pektas; [2023]
    Nyckelord :Hållbarhet; sjuka hus; återvinning; kasein; betong;

    Sammanfattning : Kvarteret Silverskopan som ligger i centrala Stockholm har sedan länge haft problem med fukt i fastigheterna. De mätningar som gjorts har visat tydliga resultat på höga fukt- och kaseinhalter.  Kasein är ett protein som finns i mjölkprodukter och är ofarligt när det förekommer i torr miljö. LÄS MER

  4. 3. Wetland restoration on Öland : a short-term evaluation of vascular plant community composition after topsoil removal and reinstated grazing

    Master-uppsats, SLU/Dept. of Ecology
