The current study is aimed to utilize the microwave for isolation of colorant from neem bark and its application onto chemical & bio-mordanted cotton fabric. For the purpose, aqueous, acid and organic media have been employed to isolate the colorant and to make its application onto surface modified and bio-mordanted cotton fabric followed by microwave treatment up to 6min. It is found that using optimum extraction and dyeing conditions, acceptable fastness properties have been rated when 9% of Al & Fe, 7% of tannic acid as pre chemical, 7% of acacia, 9% of henna, 7% of pomegranate & 5% of turmeric extract as pre bio mordants. Similarly, 5% of Al, 9% of T.A, 7% of pomegranate, and turmeric extract as post-mordants have been employed. It is recommended that isolation of colorant & dyeing under MW treatment has not only improved the natural dyeing process but also the addition of herbal-based bio-mordants have made the dyeing process more sustainable & ayurvedic. So it is concluded that microwave treatment has not only explored the coloring potential of neem bark but also made possible use of bio-mordants for making process more green with excellent color characteristics under reduced optimal conditions. |
