    Nyckelord :Chitosan; Digital printing; Valve-jet printing; ChromoJet printer; Antibacterial textile; cotton fabric;

    Sammanfattning : Throughout history, the spread of microorganisms has caused much damage including infectious diseases and deaths. Ever since humans realized the impact of bacteria especially on population health many efforts have been done to combat the spread of pathogens. LÄS MER

  4. 3. Effekten av flyktiga fettsyror (VFA) på tillväxten av mikroalger

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Raghad Kattan; Lina Kaakeh; [2023]
    Nyckelord :Mikroalger; anaerob jäsning; VFA; avloppsvatten;

    Sammanfattning : Anaerob jäsning antas vara en bra och effektiv metod för behandling av organiskt avfall. Avloppsvatten från denna process är mer utmanande beroende främst på dess höga innehåll av bland annat flyktiga fettsyror (VFA). LÄS MER

  5. 4. Using biological conversion to increase the value of short-chain fatty acids by mixed cultures

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

    Författare :Elisabeth Beach; [2023]
    Nyckelord :Ethanol; Mixed culture; Volatile fatty acids; Anaerobic digestion;

    Sammanfattning : The development of anaerobic digestion processes has gained recognition for its potential for producing volatile fatty acids alongside bio-alcohols. In addition, the fermentation process and the products produced from biological fermentation have the possibility to overcome the abundance of organic waste in our society, which is potentially immensely rich in untapped valuable potential products.

  7. 5. Urea-Based Treatments of Unretted Hemp Fibres from Residual Streams

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

    Författare :Danilo Esteban Ortiz Sarasty; [2023]
    Nyckelord :Finola waste; stalks; unretted hemp fibres; degumming; cold urea alkali; microwave-urea;

    Sammanfattning : More sustainable and efficient degumming methods are required to extract finner bast fibres, especially from agro-industrial waste streams such as stalks from hemp for food purposes. For this reason, in this study, two urea-based treatments were evaluated as degumming alternatives for unretted hemp fibres from residual streams, one at cold and alkaline conditions (CUA) and the other in combination with microwave radiation (MWU).
