Abstract

M Sumithra and N Vasugi Raaja

In the present study the methanol extracts of Ricinus communis, Senna auriculata and Euphorbia hirta were screened for their antimicrobial efficiency and the combinations (1:3:2) and the condition 20kgf/cm2 Pressure, 20m/ min rpm were standardized for the selected herbs. The herbal extracts were applied on the four variant of denim fabric directly by using dip method. The antimicrobial activity of the finished fabrics was assessed against bacteria that normally exist like Escherichia coli and staphylococcus aureus. To enhance the durability of the finished fabric, micro encapsulation and nano encapsulation of the herbal extracts were performed and the results showed good resistance for microbes.
