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

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

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

   Abstract : 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).

3. 2. Fibres from agricultural hemp waste

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

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

   Abstract : 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. READ MORE

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

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

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

   Abstract : 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. READ MORE

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

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

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

   Abstract : 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. READ MORE

6. 5. Preparation of films and nonwoven composites from fungal microfibers grown in bread waste

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

   Author : Maximilian Köhnlein; [2020]
   Keywords : bread waste; chitin; chitosan; filamentous fungi; film; fungal cell wall; fungal microfibers; glucosamine; mycelia; N-acetyl-glucosamine; nonwoven; wet-laid;

   Abstract : Unsold bread makes up a signification fraction of waste occurring in Swedish supermarkets. This thesis seeks to address the problem of food waste, by cultivating filamentous fungi on bread waste and producing chitinous films and nonwovens from them. READ MORE
