EXTRACTION OF NATURAL DYES, ITS APPLICATION IN TEXTILE COLORATION AND COMPARATIVE STUDY WITH REACTIVE DYES (Pages : 24 - 30)

The worldwide demand for natural dyes is of great interest due to the increased awareness of medicinal properties. Also non-toxic, biodegradable and eco-friendly properties make them exceedingly popular. It is due to the technical drawbacks, such as, color yield, complexibities of dyeing process, limited shades, reproducibility and fastness properties which restricts their usage in textile dyeing. So standardization of dyeing techniques needs to be explored for successful commercial use of natural dyes. Turmeric, Neem and Henna are one of the most ancient spices is commonly used as a dye. These are perennial plants found in the tropical regions of Southern Asia. These give vibrant yellow-orange, light brown and dark brown color. These can be also used to dye fabrics. The dye solution used for dyeing was extracted by boiling the meshed form of Turmeric, Neem and Henna individually. Then the extracted solution used dyeing 9(nine) derivatives of knitted fabric and one woven fabric by exhaution process in lab dyeing machine under different dyeing conditions. Next to it the individual shade of dyed fabrics were scanned through spectrophotometer to get recipe for reactive dyes. The color fastness to wash, color fastness staining, rubbing, perspiration for the dyed fabrics with Turmeric, Neem & Henna were done to compare with the fabrics dyed with reactive dyes. Again, due to shortage of time the costing for both natural dyed fabric and reactive dyed fabric were not done.Download
