DEVELOPMENT OF DIFFERENT DYE SHADES OF BEETROOT DYE WITH NATURAL MORDENT (MYROBALAN) ON BAMBOO FABRIC

摘要

The ability of natural dye to colour textiles has been known since ancient times. Natural dyes or colorants derived from plants, invertebrates or minerals. The majority of natural dyes are vegetable dyes from plant sources- roots, berries, barks, leaves and wood and other organic sources such as fungi and linches. Natural dyeing really stands for the pride and glory of the craft of India as it has been in Indian culture since long time. Because of the beauty of its results, those who use them claimed that no chemical dye has that lustre and the soft light and shadow that gives so much pleasure to the eyes. Many natural dyes require the use of chemical called mordants it helps to bind the dyes to the textile fibres. In the present research, shades of natural dyes(beetroot dye) was developed using natural mordant (myrobalan) on Bamboo fabric. Colour fastness to washing, rubbing, and sunlight of the dyed fabric was assessed. Rubbing fastness was assessed through crock meter both in dry and wet condition, washing fastness was determined by ISO test no. Ⅲ. To analyse the result, two scales have been used, one was for assessing change in colour and other was for staining. Sunlight fastness was assessed by using ISO blue standards.
