Antibacterial properties and anti-ultraviolet ray of B.mori silk fabrics treated with aloe nano-silver

Aloe silver nanoparticles were biosynthesized using aloe extract and applied to treatment of B.mori silk fabrics. The antibacterial and anti-UV performances of the treated silk fabrics were tested. The results showed that the treated fabric was imparted a antibacterial rate of 99.9%. When the silver content on silk fabric was about 97.35mg/kg, the bacterial efficacy was 99.80%, at the same the laundering durability was satisfied. The UPF value of the fabric enhanced from 6.52 to 33.43, while the average transmissibility of fabrics to UVA, UVB decreased from 30.21%, 11.96% to 5.75%, 2.50% respectively. The treated silk fabrics had benign antibacterial properties against the staphylococcus aureus and bacillus coli, and the anti- ultraviolet protection was enhanced distinctly.
