Meltblown Lab

The Nonwovens Institute at North Carolina State University offers state-of-the-art technology and deep expertise in meltblown nonwoven applications.

The Nonwovens Institute features a 1.2-meter wide Reifenhäuser Reicofil pilot line with recently updated software and control systems. Along with NWI’s many years of experience in developing meltblown nonwoven applications, this stand-alone machine provides the ability to test a wide range of polymers, including polyolefins, polyamides, polyesters, elastomers, PLA and many others. Importantly, this meltblown system includes in-line electrostatic charging capability (corona).

NWI’s facilities also include laboratories dedicated to polymer characterization, fiber extrusion and lab scale meltblown. Our Analytical & Physical Testing and Filtration Media labs offer the ability to analyze and evaluate material performance according to many industry-specific standard test methods, including, notably, ISO-17025 for filter media.

If you have questions about running trials at NWI, please email us at nonwovens@ncsu.edu.

If you wish to use the pilot equipment or have some testing done, you will need to have a Fabrication and Testing Services Agreement in place.
