Abstract


In this research an attempt has been made to reduce the axillary odour formation in textile material with the help of Terminalia chebula finish. Knitted cotton textile materials with different structures were used for in-vivo analysis. The initial study shows that, the odour formation in textile material is strongly correlated with the thickness and mass per square meter. The odour analysis was repeated after the Terminalia chebula extract finishing. The subjective analysis results of treated fabric shows significantly lower odour intensity after in-vivo study. Further it is also confirmed the bacterial reduction in the axilla worn material objectively. The bacterial isolation was performed and count was analysed and the results shows a significant reduction in bacterial percentage. The test results on the effectiveness of Terminalia chebula treatment against the odour causing bacterial strains like Staphylococcus aureus (MTCC 737), Corynebacterium Sp (MTCC 8730), Corynebacterium Sp (ATCC 3021), B. licheniformis (MTCC 429), M. luteus (ATCC 49732), Corynebecteriurn acnes (MTCC1951), Pseudomonas Sp.,(MTCC 6628), Escherichia coli (MTCC 1687), shows that there is a maximum bacterial reduction in terms of zone of inhibition up to 42 mm. The presence of active substance like tannins, phenols and saponins are the major reason for inhibiting odour formation. Hence, this study suggests an alternative and eco friendly way of finishing in textile material against odour propagation and retention.
