摘要：
This study aimed to develop antibacterial hemp fabrics with good washing durability using a facile preparation method compatible with the current technologies of the textile industry. Silver nanoparticles (AgNPs) were synthesized on hemp fabrics using silver nitrate as a precursor (0.5, 1.0, 1.5, 2.0, and 2.5 g/L) and trisodium citrate as a reducing agent. The obtained spherical AgNPs had a mean diameter of 9.4 +/- 3.1 nm. The treated fabrics were characterized for their morphological, thermal, tensile, antibacterial, and ultraviolet (UV)-blocking properties. AgNPs imparted a yellowish-brown color to the fabrics and enhanced their thermal stability by promoting char residue formation. However, the nanoparticles reduced the tensile strength compared to the untreated fabric. We observed durable antibacterial activity in samples showing > 90% bacterial reduction after 30 standardized washings. All AgNP-treated samples exhibited excellent UV protection properties (UPF rating of 50+). Overall, our study successfully demonstrated a facile finishing of hemp fabrics for protection against bacteria and UV radiation.
