A Real-Life Based Evaluation of the Effectiveness of Antibacterial Fabrics in Treating Atopic Dermatitis

Table 1

Time-trend comparison of antibacterial effectiveness of conventional AD clothes against S. aureus according to the standards ISO 20743 and ASTM E 2149-01. Results depicted as log 10 reduction factors, means of triplicates with SDs. The ISO setup revealed a strong antibacterial effect for the silver-polyamide and the zinc-containing lyocell fabrics. The weakest activity was obtained with the Silk-Aegis sample. Right side: Evaluation of the antibacterial activity of the Silk-Aegis sample via ASTM test. Note failure of activity for the silk garment.
