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

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

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

    Abstract : 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.

  4. 3. Lagring av skogsflis med och utan täckning : substansförlusters påverkan av nederbörd och vind

    University essay from SLU/Dept. of Energy and Technology

    Author : Daniel Wetterholm; [2021]
    Keywords : biobränsle; bränslekvalitet; substansförluster; fukthalt; data analys; lagring;

    Abstract : In the supply chain for wood chips, storage is a neccesary part due to seasonal demand. During storage there are several mechanisms occuring, cell respiration, biological degradation and thermo-chemical oxidative reaction. All of the mentioned mechanisms lead to increased temperature, loss of dry matter and energy. READ MORE

  5. 4. Paper Machine Press Felt Monitoring : A Case Study on PM2 in Karlsborg

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Aron Laurell Håkansson; [2021]
    Keywords : paper machine; press fabric; press felt; vibration; condition monitoring; pappersmaskin; pressduk; pressfilt; vibration; tillståndsövervakning;

    Abstract : Press felts are highly critical components of the paper machine. A degraded press felt could lead to paper web breaks, which requires the paper machine to be restarted. Moreover, a degraded felt influences the quality of the paper, leading to paper disposal. READ MORE

  6. 5. Study of Monitoring Circuitry for Ageing in FPGAs

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Pengxiang Cheng; [2021]
    Keywords : FPGAs; Ageing; Technology and Engineering;

    Abstract : Along with the down-scaling of CMOS technology, ageing has become one of the most important reliability challenges in CMOS devices. Ageing is defined as degradation in certain device characteristics such as delay, which can result in failure. READ MORE
