Abstract
The study investigated effects of extraction and mordanting method of natural dye from teak leaves on coloration of cotton fabric. Specifically, it determined: effects of two extraction methods of natural dye from teak leaves on hue intensity of dye stuff, and time efficiency, colour shades; effect of mordanting on colour shades dyed of cotton fabric, and acceptability level of the dyed cotton fabric. It was an experimental research. Extracted dye was applied to mordanted and non- mordanted cotton fabric. Ten panelists evaluated dyed cotton fabric samples labeled. MM (maceration mordanted), DM (decoction mordanted), MNM (maceration non-mordanted), and DNM (decoction non-mordanted). Data were analyzed using mean. Major findings reveal, among others, decoction extraction proved more efficient, as it yielded a concentrated hue of the dye stuff, and required lesser extraction time; DM fabric sample yielded highest mean score of (X̅= 4.00). Mordanted samples yielded deeper hue, and were more acceptable, with acceptability mean scores of (X̅= 3.38) and (X̅ = 4.00) for MM and DM respectively. It was concluded that teak leaves have dyeing potentials and can be used as a source of textile dye.
