The idea of extracting dyes from plant (natural) sources is to avoid the environmental pollution and water pollution. Present days with global concern over the use of eco-friendly and biodegradable materials, considerable research work is being undertaken around the world on the application of natural dyes in textile industry. Dyes derived from natural sources have emerged as an important alternative to synthetic dyes. In present work the bark of Acacia Arabica (kikar) was used for extraction of dyes highlighting the importance of ecofriendly approach. The dyes extracted from bark of Acacia were used on four types of different fabrics such as cotton, khaddar, silk and wool and tested for their color fastness to washing properties. The best color and washing fastness were observed on a fabric which was dyed with alkaline extract. The analytical studies such as UV-Visible and IR spectrophotometry were also performed on the extracts. Moreover, the dyes obtained from the plant are used in effective manner because these are mostly eco-friendly, biodegradable, less toxic, and less allergenic as compared to synthetic dyes. It is suggested and recommended that with financial aid and problem based cooperation of textile industries, application of natural dyes can be explored in better way.
