In light of the coronavirus pandemic and the increasing number of hospital infections around the world involving multidrug-resistant pathogens, antimicrobial textiles are coming back into focus. An innovative, ultrasound-based finishing technology developed by Sonovia, Brückner Textile Technologies, and Weber Ultrasonics now offers some crucial advantages: because the impregnation meets industrial requirements for wash resistance, it remains effective for a long period of time – even against coronaviruses. Furthermore, the new “sono-finishing” process minimizes the environmental impact associated with conventional textile finishing.
