Following the recent trend of using natural ingredients from bio-macromolecules, biomaterials and plant extract in textile chain, this research aims to develop an antibacterial textile finishing with tannin extracted from piper betle plant. The extracting processes were carried out with different solvent: distilled water, ethanol 30 %, ethanol 50 %, ethanol 70 % for 60 minutes. Two important types of fabric, including cotton and CVC (Cotton/Polyester) were padded with piper betle extracts, then dried at 60 oC for 5 minutes. The presence of tannin on fabric after treatment was determined by FeCl3 test and FT-IR spectrum. The antibacterial effect of finished fabrics was proved according to ASTM 2149-01 standard. The test was performed with E. coli ATCC 25922 and S. aureus AATCC 6538. The final results exhibited good antibacterial activity of 83.02 %, 65,33 % against the bacteria E. coli and 93.88 %, 85.14 % against the bacteria S. aureus on cotton and then CVC fabrics. | Antibacterial finishing on cotton 100 % and CVC fabrics with tannin from piper betle extract
