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).
