Abstract:
In this investigation, a sustainable Moka pot extraction method is utilized to extract dye from coffee
grounds, eliminating the necessity for harmful solvents. Before silk dyeing, the silk undergoes surface
treatment, and the derived coffee dye is employed to dye silk yarn with varying times (1.0, 1.5, 2.0, and
3.0 h) and temperatures (85 °C and 120 °C), using a pressure cooker at 120 °C. UV-vis spectrometry gauges
the absorptivity of dye solutions before and after dyeing under diverse conditions. The dark brown hue in the
dyeing liquors, post-pressure cooker usage, is attributed to residue removal during pressurization, potentially
enhancing dye affinity on the silk surface. CIELAB parameters (L*, a*, and b*) measure the color of dyed
silk yarn, exhibiting a natural brown shade. Although bleaching marginally impacts tensile strength, dyed silk
yarn provides higher elongation than pristine. FT-IR analysis distinguished coffee-extracted dye, dyed silk
yarn under various conditions, and untreated yarn. This innovative approach highlights the potential of
utilizing coffee remnants as an environmentally sustainable dye for silk yarn, offering conscientious
alternatives in the textile sector. The research emphasizes efficient coffee ground utilization and eco-conscious
dyeing practices for sustainable textile production
