Abstract
This study evaluates the potential of teak wood extract (Tectona grandis) as a natural dye for traditional woven yarns by comparing the effectiveness of different fixation techniques in enhancing color retention and stability. A spectrophotometric analysis was conducted to measure lightness (L*), red-green shift (a*), and yellow-blue shift (b*). Four fixatives - Aluminum Sulphate (Al2(SO4)3), Natrium Bicarbonate (NaHCO3), Calcium Carbonate (CaCO3), and Ferro Sulphate (FeSO4)—were tested to assess their impact on color transformation. The results indicate that Ferro Sulphate induced the most intense color transformation, producing deeper and darker hues, while Aluminum Sulphate yielded the most uniform and stable coloration. Calcium Carbonate enhanced lightness, whereas Natrium Bicarbonate resulted in moderate color absorption. These findings confirm the viability of teak wood extract as a sustainable alternative to synthetic dyes, supporting eco-friendly textile dyeing practices. Furthermore, this study provides scientific insights into fixation techniques, offering practical applications for both artisans and the textile industry.
