Extracting pigments and oils from spent coffee ground to utilize in textiles
Types of food materials: Arabica spent coffee ground
Product obtained from research:
– Dyestuff extracted from spent coffee ground for dying cotton, silk and nylon
– Oil extracted from spent coffee ground for developing an antimicrobial agent for silk
The research used Arabica coffee grounds by developing dyes and decorative substances for textiles in order to utilize and increase the value of the residue from the coffee production process. It was done by researching the extraction of dyestuff and oil from coffee grounds.
Development of dyestuff from spent coffee grounds for cotton, silk, and nylon. This was considered natural and environmentally friendly dyes. Tests on staining, color fastness, antibacterial, and UV protection properties were examined. It was found that the dyestuff was effective in dyeing textile products, especially silk, giving beautiful shades.
Development of decorative substances from oil extracted from spent coffee grounds by using the micro-encapsulation technique. It was found that microcapsules can be decorated on silk to have better antibacterial properties against S. Aureus. In addition, microcapsules of oil from spent coffee grounds can be applied in other fields at the industrial level, such as food and cosmetics.
