Extraction and Optimization of Natural Dye from Asphodellus tenufolium

Although plants exhibit a wide range of dyes, not all of these pigments can exhibit as dyes. Jangali Pyaz commonly known as vanpyaz (Asphodellus tenufolium) is a weed plant which is shredded off as a waste was exploited as a source of natural dye for Tassar Silk with objective of standardizing conditions of extraction and dyeing, fastness properties, eco-friendliness and colour absorption. The optimum dyeing conditions were 4g concentration, 60 minutes extraction time and 75 minutes of dyeing time. All the samples dyed with Jangli Pyaz with different mordants showed fairly good to very good washing and rubbing fastness. The colour gamut of Tassar Silk samples dyed with Jangli Pyaz indicated a red yellow one and the metal complexes (mordants) shift the colour of the dye. The dyed samples ranged from light peach to candy pink and grey with different mordants.
