P066_0320_ BIOACTIVE NONWOVENS WITH SUPERABSORBING POLYMERS FOR FILTERING FACEPIECE RESPIRATORS USED IN HEAVY-DUTY APPLICATIONS AT HIGH TEMPERATURES AND HUMIDITY

Abstract

Within the present study the efficiency of filtering nonwovens with bioactive and sorption properties have been investigated. Two types of nonwovens with bioactive agents and superabsorbing polymers were manufactured using melt-blown technology from polypropylene along with pristine nonwoven serving as a control sample. The influence of additives on basic filtration properties (paraffin oil mist, sodium chloride penetration, pressure drop) were assessed. Moreover, their antimicrobial properties as well as water sorption capacity were determined to confirm their applicability as a multifunctional layer in the construction of filtering facepiece respirators.
