Spunbond and meltblown materials can be electrostatically charged to improve their filter performance. The ecuTEC+ electro-charging unit from the Nonwoven BU of the Manmade Fibers segment of Oerlikon Management AG, Pfäffikon/Switzerland, is part of the delivery scope of all meltblown systems currently sold for the manufacture of protective mask nonwovens.
The patented solution is characterized by its high flexibility: ecuTEC+ stands out above all as a result of its diverse applications, which can be electro-charged. Nonwovens manufacturers can freely choose between numerous variation options and set the optimal charging method and intensity for their specific filter applications. Additionally, EPA and HEPA-class filter media can also be manufactured using the ecuTEC+.
This meltblown technology, with which among other things nonwovens for respiratory masks can also be manufactured, is recognized as being a technically very efficient method for producing highly-separating filter media made from man-made fibers. The capacities for respiratory masks available in Europe to date are predominantly manufactured on Oerlikon Nonwoven systems.
