Modification of Nylon fabrics with HDTMS compound and silver nanoparticles which prepared via bio-reduction method using banana peel extract (Musa paradisiaca Linn.) has been conducted in this research. That modification can increase the quality of Nylon fabrics so they have antibacterial and self-cleaning properties. The types of Nylon fabrics in this research are Nylon fabric (Ny0), Nylon-Ag (Ny1), Nylon-HDTMS (Ny2), Nylon-Ag-HDTMS (Ny3), and Nylon-HDTMS-Ag (Ny4). The silver nanoparticles were characterized by using spectrophotometry of UltraViolet-Visible. Antibacterial activity against gram-positive and gram-negative bacteria was analyzed by measuring the clear zone around the sample. While the contact angle test was performed by the sessile drop method. Silver nanoparticles have a maximum peak at the wavelength of 440.50 nm. Nylon-Ag shows the highest antibacterial activity against E.coli and S. aureus. The inhibition zone of Nylon-Ag at 54 hours of incubation time is 97 times higher than the inhibition zone of Nylon without modification at 24 hours of incubation against E.coli. Likewise, with the inhibition capacity of Nylon-Ag in inhibiting the growth of S. aureus, Nylon-Ag has antibacterial activity at 72 hours incubation time of 85 times higher than Nylon at 48 and 72 hours incubation. However, Nylon-HDTMS-Ag has the greatest contact angle, that was 110.63o. © RASĀYAN. All rights reserved.
