Extraction and Effect of Mordating Method on Dye Absorbtion of Natural Dye Extraction from Alcanna on Regenerated Fibre

Nature is full of wonderful colours and people has been exploring on different coloured garments, food and many other daily use products according to trend. There has been evidence from the ancient reports and writers that there they were used in all times and nearly thousands of natural sources of dyes. There is always a trend and separate demand for eco-friendly products in the international market and its easily possible to master the techniques of dyeing using natural dyes. In a search for newer natural sources and techniques attempts, dye has been extracted from selected Alkanna and its applied on the regenerated fibre yarn “bamboo” with Quercus Infectoria natural mordant. Effect of the dyeing, methods of extraction and the mordant has been visualized on the strength of colour and its fastness properties of the dyed sample. In bamboo, regarding its general appearance the sample dyed with tree bark using Quercus Infectoria mordant with pre-mordating technique was rated “good”. Texture and lusture of the sample was rated as good and medium respectively. The weight of the sample has maximum increase level from its orginal weight dyed with Quercus Infectoria mordant by using the pre-mordant technique has maintained the fabric thickness of the fibre yarn, it has also increased the strength of the fibre. The colourfastness of the dyed bamboo sample with Alkanna.had very good light fastness with pre-mordating technique. In general the sample that has been dyed using the following technique has good to excellent colour fastness to both wet and dry crocking with good colourfastness resistance to washing. Colour to the attire or fibre gives a pleasant look to the substrate product, but also express ideas of the wearer. Though the existence of colour remains from decades the extracting technique and usage of colour remains from India. People demand colours for the expressive idea of one self and for decoration purpose also. In many years there has been an interest towards eco-friendly and natural dyes. The main reason for the usage of these techniques are they are bio-degradable and higher compatibility with the environmental advantages with lower toxity and allergies comparative to synthetic dyes. In this study of natural dyes and colour that are extracted from tree bark called Alkanna and to apply on textile material with Quercus Infectoria mordants. These natural dyes also give some medicinal values and properties also.
