Hydrated Deep Eutectic Solvents for the Sustainable Valorization of Textile Waste
Hydrated metal‐based deep eutectic solvents (DESs) composed of zinc or calcium chlorides, organic acids, and water were developed as low‐viscosity, room‐temperature‐stable media for the sustainable valorization of cotton waste. These formulations effectively disrupted the cellulose fiber structure and processed microcrystalline cellulose, medical‐grade

Acid Sulfite Pulping of Hemp: Effects of Processing Conditions on Lyocell Pulp Quality
Industrial hemp is emerging as a promising renewable source for next‐generation textile fibers. This study evaluates whether acid sulfite pulping can produce hemp‐based dissolving pulp suitable for lyocell manufacturing. While the process is historically linked to increased cellulose accessibility, it did not achieve the low lignin content and ...
