However, the results indicated that silver nanoparticles easily agglomerate in ambient condition. Therefore, an in situ synthesis method was conducted through the reaction between the multi-amino compound (RSD-NH2) and the silver nitrate solution. The surface morphology, whiteness, silver

content, antibacterial activity, and washing durability of nanosilver-treated fabrics were examined. The experimental results confirmed that the in situ synthesized silver nanoparticles evenly distributed on the surface of fibers. The inhibition zone and the antibacterial rate demonstrated that the finished fabrics have an excellent antibacterial property against S. aureus and E. coli. When the nanosilver-treated fabric which included a silver content of 98.65 mg/kg was washed 50 times, the silver content slightly decreased from 98.65 to 81.65 mg/kg and the corresponding whiteness increased.

However, it Foretinib nmr is surprising that the antibacterial rate click here is still more than 97.43% for S. aureus and 99.86% for E. coli after 50 washings.
