Microwave-assisted eco-dyeing of bio mordanted silk fabric using cinnamon bark (Cinnamomum Verum) based yellow natural dye

The revival of sustainable plant-based dyes, now a day is becoming the demands of the global community in every field. The current study has been concerned with the exploration of cinnamon bark as a source of yellow natural colorant for silk dyeing. The yellow dye has been extracted in various media and exposed to microwave treatment for up to 6 min. The results show that dyeing of irradiated fabric at 35 degrees C for 45 min using an irradiated extract of 3 pH containing 1 g of salt as a leveling agent has given excellent results. Salt of Al& Fe as sustainable chemical mordants & extract of acacia, henna, rose, pomegranate and turmeric as sustainable biomordants employed have not only given new shades but also improved fastness ratings. Conclusively, the microwave treatment has not only enhanced the extraction yield of dye from cinnamon bark but also has made the process more sustainable and ecofriendly by utilizing bio-mordants extracts.
