- Abstract
Hibiscus rosa sinensis, known colloquially as Chinese hibiscus, China rose, Hawaiian hibiscus, rose mallow and shoeblackplant, is a species of tropical hibiscus, a flowering plant in the Hibisceae tribe of the family Malvaceae. The flowers and other parts of the plant are used to make medicine. This paper describes the application of Hibiscus rosa sinensis bio extract on woven cotton textiles for antibacterial finish. With a view to understand the effect of various functional groups present in the plant, molecular characterisation was done using FTIR. Chemical groups responsible for antibacterial behaviour and the chemical structure of this plant were investigated through GCMS. Hibiscus rosa sinensis treated fabric has greater colour depth (K/S value) at higher concentration in comparison to fabrics treated with lower concentrations. Zone of inhibition in treated fabrics reveal that the antibacterial effect is more potent against gram positive bacteria. Cotton fabrics also generate fragrance after treatment with Hibiscus rosa sinensis. Fragrance intensity ratings of 200 respondents have been documented and evaluated.
