In this paper, the dye ability of polyester/wool fabrics after plasma sputtering treatment was investigated. The polyester/wool fabrics were sputtered by copper particles. The natural dye (madder and weld), metal complex and disperse dyes were used for dyeing at the boil point. The Scanning Electron Microscope (SEM) was applied for morphological study and the elemental analysis was studied by the Energy Dispersive X-Ray (EDX). Results were monitored by using reflectance spectrophotometer analyses. The results show that, the dye ability of the polyester/ wool fabrics after plasma sputtering is improved and this effect is more pronounced for natural dyes. This study may offer a way to achieve better dye ability of polyester/wool blend fabrics.

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.
