In this study woven cotton fabric is treated with geranium oil microcapsules through pad dry cure technique to incorporate aroma finish. Geranium oil microcapsules were prepared by complex cocervation technique. Abrasion resistance and wash durability of aroma finished fabric was tested and analysis for retention of aroma was carried out by olfactory analysis done by 25 respondents. Analysis for presence of microcapsules was done through Scanning Electron Microscope (SEM). Wash fastness and abrasion resistance of aroma finished fabric by oil microcapsules with pad-dry-cure technique were tested against the fabric finished by direct method. The findings of the present study revealed that wash fastness and abrasion resistance has increased manifold in fabric treated with oil microcapsules as compared to direct method. On the surface of microencapsulated treated fabric numerous microcapsules containing geranium essential oil inside the matrix varying in their size and shapes were found, however in case of direct method some residue of citric acid was observed by SEM.
