The revival of natural dyeing techniques offers an environmentally sustainable alternative to synthetic dyes in textile production. This study investigates the use of teak leaves (Tectona grandis) as a natural dye source for cotton fabric. By examining the dye extraction process, mordanting, and dyeing techniques, this research aims to provide insights into the practical application of natural dyes and their potential benefits.
Material:
Cotton fabric (pre-washed)
Fresh or dried teak leaves
Mordant (alum)
Water
Large pot
Methods:
Preparation of Teak Leaves: Teak leaves were collected and cleaned. A dye extract was prepared by boiling the leaves in a large pot with water, simmering for 1-2 hours to ensure a concentrated dye solution.
Fabric Preparation: The cotton fabric was pre-washed to remove impurities. An optional mordanting process involved soaking the fabric in an alum solution for an hour to enhance dye absorption.
Dyeing Process: The pre-washed (and optionally pre-mordanted) fabric was immersed in the teak leaf dye solution, simmering for 30 minutes while stirring occasionally to ensure uniform color distribution.
Post-Dyeing Treatment: After dyeing, the fabric was rinsed in cold water until the water ran clear to remove excess dye. The fabric was then air-dried away from direct sunlight to prevent fading.
Result :
The teak leaf dyeing process produced a range of earthy tones on cotton fabric, including various shades of brown depending on the concentration of the dye and the duration of the dyeing process. Mordanting significantly improved color fastness and intensity, demonstrating the importance of this step in natural dyeing.
Color results varied with fabric type and dyeing conditions, emphasizing the unpredictable nature of natural dyes. The study highlights the potential for teak leaves to offer a sustainable and aesthetically pleasing dyeing solution, contributing to the broader field of natural textile coloration.
