NanoSilver Fabric - Investigation and information

Information Link:

Abstract The influence of reactive dyes with massive chromogene and nanosilver on ultraviolet protective factor (UPF) values of lightweight cotton fabrics was investigated. The effect of nanosilver on the color of cotton fabrics and on antibacterial effectiveness was also determined. AATCC Test method 183-1998 was used for the calculation of the UPF of lightweight cotton fabric. The antibacterial activity was determined according to ASTM Designation E 2149-01. The research shows an increase in the UPF values of lightweight cotton fabrics when they are pale red or pale navy dyed with nanosilver. Cotton fabrics treated with 80 nm nanosilver showed inhibition of the growth of Streptococcus faecalis and Staphylococcus aureus. Changes of color are observed on dyed cotton fabrics treated with nanosilver.
