COMPARATIVE ASSESSMENT AND FEASIBILITY ANALYSIS OF NATURAL DYE SOURCES FOR COMMERCIAL APPLICATION

M.Anandhan

Abstract: Natural dyes extracted from plants are potential renewable sources which can be applied for dyeing of wool, silk and cotton. But due to non-availability of sufficient natural dyes sources , repeatability and cost the use of natural dyes for commercial dyeing application has declined considerably. But by correctly identifying the natural dye sources, the natural dye can be utilized by industries on a commercial scale. For the identification of the potential dye sources, a quantification technique has been generated. Based on the quantification technique the identified potential dye sources can be evaluated for commercial suitability. Two potential natural dyes were used as source of colour extraction. Dyeing of cotton fabric with natural colorant has been done. The dyeing process was carried out with different mordant. Wash fastness of dyed sample has been evaluated. The wash fastness, time estimation and water required were compared among the two natural dyes sources and it is prioritized for commercial application.
