Determination of Antimicrobial Activity of Cotton and silk Dyed Fabric Material by Using Natural Dye Sources

Abstract This Antimicrobial research work has determination of the antimicrobial activity of cotton and silk fabric material which dyed with the natural dyes. Some natural dye sources such as Turmeric, Logwood, Marigold, Madder and Basil were selected for dyeing of ecofriendly cotton and silk material. These dyes were extracted through aqueous medium before applied on clean cotton and silk fabric material by dyeing method. In this research the antimicrobial activity of cotton and silk dyed material against Escherichia coli (G-) & Staphylococcus aureus (G+) is evaluated. And for determination of this antimicrobial activity the well diffusion method was performed on both cotton and silk dyed material by using three different increasing volumes of solutions. The antimicrobial effect of these cotton and silk dyed material was also evaluated after repeated washing cycle through water medium. This work can provide the data towards creation of ecofriendly and antimicrobial fabric material as a development in textile industries. The natural dyes which were used for this work in the form of dyed cotton and silk fabric material gave good activity against harmful microbes.
