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

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

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

    Sammanfattning : 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.

  3. 2. Influence of supercritical carbon dioxide (scco2) dyeing parameters on color fastness of polyester fabric dyed with disperse dye : A study towards minimizing the energy consumption of polyester (pet) fabric dyeing with azo disperse dye

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Tapas Das; [2023]
    Nyckelord :Supercritical fluid dyeing; polyester PET fabric; coranger orange PE3330; color fastness; ideal dyeing conditions; eco-friendly;

    Sammanfattning : Amid growing environmental concern and continuous depletion of natural resources (such as water), the textile industry is constantly searching for sustainable production process. Traditional dyeing processes, notorious for their enormous water consumption, have led society to search alternative dyeing method. LÄS MER

  4. 3. Fibersläpp, vattenavvisning och färgändring hos textilier före och efter en simulerad åldring

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Filippa Ottosson Geete; Tilda Larsson; Kajsa Jansson; [2022]
    Nyckelord :microfiber; microplastic; fiber shedding; simulated ageing; simulated aging; ageing; polyester; piece dyed; solution dyed; mikrofiber; mikroplast; fibersläpp; simulerad åldring; åldring; polyester; spinnfärgning; styckfärgning;

    Sammanfattning : Mikrofibersläpp vid tvätt lyfts ständigt som ett återkommande problem eftersom de små fragmenten leds ut i vattendragen och påverkar miljön negativt. Mängden mikroplaster är svåra att se och mäta vid endast visuell antydan. LÄS MER

  5. 4. Infästning av celler på bomullstopsar och hur frisättningen av DNA kan underlättas

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Caroline Drabe; [2019]
    Nyckelord :Forensics; DNA; Applied microbiology; Teknisk mikrobiologi; Technology and Engineering;

    Sammanfattning : A great number of cotton swabs from crime scenes are sent to the Swedish National Forensic Center each year for analyzation of DNA. Many of the swabs contain small amounts of cells and therefore it’s important to optimize the sampling of cells and the extraction of DNA. LÄS MER

  7. 5. Textile dyeing in Mali : possibilities for small scale effluent treatment

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Hanna Larsson; [2009]
    Nyckelord :water treatment; textile dyes; artisanal; Mali;

    Sammanfattning : Water treatment is an important issue in Mali, an arid country where the Niger River is the mainrecipient for a large part of the effluents from industrial and small scale activities. Clothes dyed withsynthetic dyestuffs are an important part of the culture in Mali. LÄS MER
