  1. 1. Fibres from agricultural hemp waste

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

    Författare :Ella Kärkkäinen; Åsa Älgbrant; Simon Kronberg; [2021]
    Nyckelord :Hemp fibres; hemp residue; unretted hemp; nonwoven hemp;

    Sammanfattning : There is an increasing demand for natural fibres in the textile industry as a consequence of the negative impact of the industry on the environment. Svensk Hampaindustri (SHI) is currently growing hemp in Sweden for its seeds. This leaves residue in the form of hemp stems that could be processed for textile products. LÄS MER

  3. 2. Investigation of the binding effect of fungal fiber (grown on apple pomace) in the formation of lyocell nonwoven textiles and their potential applications

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

    Författare :Xue Luo; [2021]
    Nyckelord :lyocell; nonwovens; binder; filamentous fungi; wet-laid; fungal microfibers; apple pomace; cellulose;

    Sammanfattning : This project combines nonwoven technology, biological technology and food waste management and seeks for this feasibility to use fungal microfiber (FM) as a binder for lyocell pro-duction and the characterizations for possible applications. Rhizopus delemar was cultivated apple pomace in liquid-state fermentation to obtain mycelia biomass. LÄS MER

  4. 3. A novel and feasible material recycling technique for end-of-life textiles as All-Cellulose Composites (ACCs)

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

    Författare :Belinda Johansson; [2021]
    Nyckelord :all-cellulose composites; end-of-life textiles; denim fabrics; ionic liquid; mechanical properties; sustainability;

    Sammanfattning : Today’s consumption of textiles generates a large volume of textile waste. Therefore, it is needed to find solutions to re-use the textile waste rather recycling fibers into new fibers. Research using pre- and post-consumer textiles in composites is ongoing and an interesting direction. LÄS MER

  5. 4. Surface functionalization of nonwoven polypropylene with BTCA polycarboxylic acid in supercritical carbon dioxide medium

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

    Författare :Md Fahad Khan; [2021]
    Nyckelord :Nonwoven polypropylene; Supercritical carbon dioxide; Surface functionalization; 1; 2; 3; 4- Butanetetracarboxylic acid; Impregnation; Environmentfriendly; Hydrophilicity;

    Sammanfattning : Nonwoven polypropylene has been utilized broadly in various hygienic and medical textile applications because of its excellent mechanical properties, chemical resistance, and minimal expense contrast with other synthetic polymers. However, the insufficiency of surface tethering groups, including adhesion, wettability, and hydrophilicity, some applications are not convenient on nonwoven polypropylene surfaces such as dyeing, printing, attachment of antibacterial and bioactive agents.

  7. 5. Snabb produktionsomställning i en tid av kris : en fallstudie gällande produktionen av operationsrockar

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

    Författare :Rebecca Josefsson; Sofie Johannson; [2020]
    Nyckelord :Production changeover; contingency; crisis; PPE; MD; nonwoven; Produktionsomställning; beredskap; kris; PPE; MD; nonwoven;

    Sammanfattning : Till följd av Covid-19-pandemin har sjukvården i Sverige fått bära mycket stor belastning, samtidigt som den globala efterfrågan och användningen av personlig skyddsutrustning (PPE) kraftigt ökat. Under våren 2020 har den globala handeln upplevt störningar, vilket haft inverkan på leveransen av PPE till sjukvården. LÄS MER
