Solid Denim: Research on New Hydrophobic Material Obtained from Post-Consumer Denim for Product Development
摘要
This research proposes and analyses a new material entirely made from discarded post-consumer denim and polymer waste. It is a solid material obtained through hot compression moulding without any reprocessing or crushing of the materials. The aim is to reduce costs while preserving the appearance of denim as much as possible, thereby allowing consumers to appreciate the material's origin and potential even at the end of its life cycle. In the production of the new recycled material through upcycling, the compression moulding process with polymers yielded satisfactory results in terms of solid consistency and preservation of the denim appearance, with finishing that enhances hydrophobic capacity, as confirmed by permeability characterization. This research presents two different materials: one utilizing denim compressed with high density polyethylene -HDPE, and the other with polymethyl methacrylate -PMMA. Permeability characterization was conducted on both materials, revealing high hydrophobic capacity in the material with denim and PMMA.
