188 Optimization and Characterization of Herbal Natural Dyes for Silk Fabric: Extraction, Application, and Functional Evaluation
Keywords:
Natural Dyes, Herbal Dye ExtractionAbstract
In the research paper "Optimization and Characterization of Herbal Natural Dyes for Silk Fabric: Extraction, Application, and Functional Evaluation," we investigate the extraction, optimization, and application of natural dyes derived from Brassica oleracea var. capitata f. rubra (purple cabbage), Alkannatinctoria roots (Ratanjot), Picrorhiza Kurroa (Kutki), and Curcuma longa roots (Turmeric) on silk fabric. The study focuses on varying pH, time, and temperature to optimize extraction conditions, followed by a thorough characterization of the dyes using color spectra, FTIR, and UV-Vis spectroscopy. Application techniques on silk fabric are optimized, and the effects of mordanting on the dyed fabric are examined. The research further evaluates the dyed silk for color value, color fastness, and functional properties, including antibacterial activity and Ultraviolet Protection Factor (UPF). This comprehensive study aims to contribute to sustainable practices in the textile industry by enhancing the understanding and utilization of herbal natural dyes.
