Summary: This study explored the use of sulfonated lignin as a natural dye for coloring wool fabrics, either alone or in combination with hydrogen peroxide. The results showed that when dyed alone, lignin particles deposited on the fiber surface were visible, but with hydrogen peroxide, there was no deposition of lignin and the color strength of the fabric doubled. The dyed fabrics exhibited good colorfastness and UV protection. ATR-FTIR spectroscopy suggested that hydrogen peroxide depolymerized lignin into smaller molecules, facilitating absorption into the wool fiber.

Summary: The cultivation and wet processing of cotton have a detrimental impact on the environment, making recycling of cotton crucial for reducing its environmental effects. This study examined the use of recycled cotton mixed with chitosan yarns and the dyeing behavior of fabrics produced from this blend as a sustainable production option. The results showed that the highest color depths were obtained from dyeing with direct dye in an alkaline medium and in the presence of salt. Furthermore, the study found that chitosan and cotton obtained from recycling could be used as a mixture instead of cotton, providing a potential alternative for sustainable production.

Summary: Sustainable chemistry is a new field aiming at achieving economic and environmental goals simultaneously. This paper proposes a cleaner and more sustainable method for dyeing cotton fabric using Direct Violet 09 and Reactive Violet 05 dye. The study shows that microwave-treated Reactive Violet 05 dye solution with 35 mL, 7 pH, and 2 g Aluminum sulfate, dyed on cotton fabric for 30 min at 60 degrees C, achieves good color characteristics. Microwave-treated Direct Violet 09 dye solution with 35 mL, 7 pH, and 2 g Potassium sulfate, dyed on cotton fabric for 50 min at 80 degrees C, also produces good results. The sustainability of the dyeing process is improved with the use of microwave radiation, as confirmed by ISO standards for colorfastness evaluation.

The idea of cogeneration becomes even more lucrative if we consider that hydrogen energy generation is clean (also known as green energy) because of its insignificant contribution to environmental pollution. These results supplement the fluctuation in effective dose theory/hypothesis of a previous study on time-dependent variations in the radiological health impact of an interim SNFS facility presented in 2021 (Leotlela, 2021).
