Abstract

The objective of this research was to study the antibacterial property on lyocell nonwoven fabric using Sappan herbal extract in order to increase the efficiency of bacterial inhibition by comparing the antibacterial properties between pure Sappan herbal extract and small particles of Sappan herb extract by nano emulsion technique into Staphylococcus aureus and Corynebacterium minutissimum Both extracts were treated on lyocell nonwoven fabric by using pad dry cure process with different concentrations of extracts at 30, 40, and 50 percent. Then, the properties of liquid absorption and air flow of fabrics were tested. The study results showed that both types of Sappan herbal extracts had longer water absorption time and less air flow compared with non-decorated lyocell nonwoven fabric. For the antibacterial activities assessed by agar disc diffusion test, the average of clear zone of lyocell nonwoven fabric decorated with Sappan herbal and small particles of Sappan herbal extracts were equal to 11.44 and 9.6 mm respectively. Concentration of 40 percent of sappan herbal extract,
