Continuous and sustainable cellulose filaments from ionic liquid dissolved paper sludge nanofibres

The textile industry is resource-intensive, which has a significant impact on global emissions and waste pollution. To meet the demand of textiles over third fibres used in manufacturing are sourced from fossil fuels. As for continues to grow, manufacturers having seek innovative approaches providing sustainable regenerative cellulose fibres. However, latest climate change pressures have uncovered grave environmental issues associated with traditional production, such as viscose process. process requires intensive use hazardous chemicals leads water pollution ecotoxicity. In addition, if forestry products unsustainably this process, can lead resource scarcity deforestation. provide holistic solution mitigating these challenges study uses by-products paper dissolved an ionic liquid produce regenerated filaments. Paper mill sludge (PMS) cellulosic by-product typically animal bedding land spreading. material been - 1-ethyl-3-methylimidazolium diethyl phosphate aid co-solvent dimethyl sulfoxide (DMSO) spun into continuous filaments production. mechanical properties found be competitive commercial viscose, promising their drop-in replacement. It also demonstrated that by increasing concentration PMS 9% 12.4%, improvement filament achieved; increase modulus ?19 GPa ?26 strength ?223 MPa ?282 MPa. These values shown other commercial, less sustainable,
