NWI Dives Deep On Fiber and Filament Extrusion

September 2023 Fiber and Filament Extrusion Fundamentals Short Course

The Nonwovens Institute (NWI), in partnership with INDA – the Association of the Nonwoven Fabrics Industry, presented the popular Fiber and Filament Extrusion Fundamentals Short Course, September  12-14, at NWI’s facilities on the Centennial Campus of North Carolina State University. The training combined classroom learning with hands-on activities in NWI’s world-class labs to highlight the critical variables and process parameters required to optimize extrusion processes for meltblown, spunbond and staple-fiber nonwovens.

“I think it is safe to say, those who attended the course left with enhanced knowledge and skills to make significant improvements in a variety of nonwoven and filament production scenarios,” said NWI Executive Director Behnam Pourdeyhimi, Ph.D., who was among the course instructors. Along with Dr. Pourdeyhimi, the course faculty consisted of:

  • Carl Wust, Ph.D., FiberVisions – an Indorama Ventures company (ret.) and Member Emeritus of NWI
  • Hechmi Hamouda, Ph.D., Faculty, NWI, NC State University (ret.)
  • Charlie King, UNIFI (ret.), and
  • Amy Minton, Analytical & Physical Testing Lab Manager, NWI

“I liked the depth of material and explantion of fiber processing and fiber testing. – Extrusion Engineer, Leading biotechnology materials company

These experts provided a broad spectrum of experience and viewpoints across many of the processes and technologies that are commercially relevant in the nonwovens industry today.

The course included not only classroom learning, but also plenty of time in NWI’s world-class Fiber and Polymer Science and Analytical Testing labs to help enforce learnings and demonstrate how fiber properties evolve during the extrusion process. 

“I thought the course was effective because it combined both industry and academic points of view” – VP of Manufacturing, Leading supplier of nonwoven fabrics

This is but one of the many courses offered throughout the year by NWI and INDA supporting workforce development across the industry. Opportunities include regularly scheduled in-person training, online courses and customized programs.
