Novel Antimicrobial Chemical Surface Treatment Technology for Fabrics

PSI-QAC technology provides high anti-microbial efficacy against a broad range of gram positive and gram negative bacteria, as well as fungi. Fabrics treated with the unique dendrimer chemistry are highly biocompatible and meet or exceed the performance of silver based treatments for first cycle use and exceed their performance after laundering. The long lasting antimicrobial efficacy has been proven for multiple textiles.
