Summary: Environmental concerns influenced by the extreme use of synthetic dyes in industries have grown exponentially. The challenges resonate with the shift in society's interest in exploring natural alternatives in dyeing applications. In this study, Cordyline fruticosa, or Ti plant, a widely recognized ornamental plant in the Philippine landscape, has been explored for its potential as a natural dye for cotton fabric dyeing applications. The dyeing parameters were the utilization of different mordants (copper sulfate and aluminum sulfate), mordanting techniques (pre- and post-), and varying dyeing times. Aqueous extraction was carried out to derive the extract and was characterized using different methods. The phytochemicals present were identified to be flavonoids, saponins, tannins, and the most prominent influencing the color, anthocyanin. In line, the UV-Vis spectra revealed a peak at 518 nm emitting red. Furthermore, the dyed cotton fabrics were evaluated using different instruments. FTIR exhibited peaks corresponding to functional groups O-H, C-H, C-C, C=C, and C-O related to the phytochemicals. The microscopic and morphological imaging showed evenness and clumping of the dye as indications of dye adherence. The color quality of the dyed fabrics implies influences of mordants, mordanting technique, and dyeing time on the overall dye uptake of the fabric. Colorfastness results convey the dyed fabrics' exemplary performance in rubbing and laundering; however, it is suggested that color stability be improved due to their relatively poor resistance to color change. This study assessed the extract's viability as a natural dye source for cotton fabrics. Keywords: Cordyline fruticosa, cotton fabrics, natural dye, SEM imaging, phytochemic

Environmental concerns influenced by the extreme use of synthetic dyes in industries have
grown exponentially. The challenges resonate with the shift in society's interest in
exploring natural alternatives in dyeing applications. In this study, Cordyline fruticosa, or
Ti plant, a widely recognized ornamental plant in the Philippine landscape, has been
explored for its potential as a natural dye for cotton fabric dyeing applications. The dyeing
parameters were the utilization of different mordants (copper sulfate and aluminum
sulfate), mordanting techniques (pre- and post-), and varying dyeing times. Aqueous
extraction was carried out to derive the extract and was characterized using different
methods. The phytochemicals present were identified to be flavonoids, saponins, tannins,
and the most prominent influencing the color, anthocyanin. In line, the UV-Vis spectra
revealed a peak at 518 nm emitting red. Furthermore, the dyed cotton fabrics were
evaluated using different instruments. FTIR exhibited peaks corresponding to functional
groups O-H, C-H, C-C, C=C, and C-O related to the phytochemicals. The microscopic and
morphological imaging showed evenness and clumping of the dye as indications of dye
adherence. The color quality of the dyed fabrics implies influences of mordants,
mordanting technique, and dyeing time on the overall dye uptake of the fabric.
Colorfastness results convey the dyed fabrics' exemplary performance in rubbing and
laundering; however, it is suggested that color stability be improved due to their relatively
poor resistance to color change. This study assessed the extract's viability as a natural dye
source for cotton fabrics.
