Textile materials are the carriers of microorganisms such as pathogenic, odor generating bacteria, mold and fungi. Fabric surface is a good growth medium for microorganisms. Microbial growth causes multiple problems to fabric as discoloration, fiber damage, staining and unpleasant odor as well as many skin problems to the weaver. All these problems decrease the quality of fabric and demand of customers. Thus, research led to develop the antimicrobial textile material which carried out extensive work for the sake of seller and buyer. Antimicrobial agent inhibits the growth of microorganism and can be applied to the textile substrates by coating, exhaust, pad–dry–cure, spray and foam techniques. The substances can also be applied by directly adding into the fiber spinning. All the above mentioned procedures are applicable generally on synthetic dyed materials. Although natural dyes are known to have medicinal and protective character, they show remarkable antimicrobial properties. They prevent the growth of bacteria and have been proven environment friendly and health protecting even preventing diseases. Antibacterial efficiency of dyed textiles could be tested qualitatively and quantitatively. Antimicrobial properties of dyed fabric can be performed on solid medium (diffusion tests) or liquid culture (suspension tests) by standard methods [35, 50, 104].
