This study aimed to create composite nonwoven fabric from polylactic acid (PLA) and nano-silver coated titanium dioxide (Ag/TiO2) for the degradation of carbaryl insecticide in water under UV irradiation. The obtained composite nonwoven exhibited a yellow-gold color and similar thermal and physical characteristics, including fiber size and a narrow size distribution, to the PLA nonwoven. Furthermore, it exhibited superior mechanical properties compared to the PLA nonwoven, particularly in terms of breaking strength. Among the composite nonwovens, the one with the masterbatch added at 10 phr (PLA-2) demonstrated the highest breaking strength. Additionally, it was noteworthy that all ratios of the composite nonwoven displayed excellent carbaryl insecticide decomposition efficiency under UV light, consistently achieving around 40% degradation. Furthermore, these composite nonwovens proved reusable for up to three cycles without a loss in efficiency. These findings suggest that composite nonwovens made from nano-silver coated titanium dioxide photocatalysts and biodegradable polylactic acid hold promise as alternative materials for the decomposition of carbaryl insecticide in natural water sources.
