The Nonwovens Institute (NWI) offers students the opportunity to participate in fundamental research in areas that address the pressing challenges in nonwovens applications and technology. Student researchers working through the NWI program benefit from a broad range of perspectives, working hand-in-hand with subject matter experts from academia and industry. NWI also offers a Graduate Certificate in Nonwovens Science and Engineeringthrough the Wilson College of Textiles at NC State University.
Students engage with NWI by partnering with faculty from the degree program of their choice. Research projects are developed by faculty and selected by NWI member companies. Students are selected based on their academic performance and capability within the industry-selected research programs. Proposal selection is a competitive process, and NWI does support the submission and selection of research proposals from faculty at other universities.
Our students will graduate with a degree in the discipline to which they are admitted, but their research will be focused on a topic of relevance to nonwovens.
The IAB meets semi-annually in the Spring (May) and Fall (November). The first half-day and full second day of the IAB meeting are designed for Core Research Presentations and Reviews. The morning of the third day is for the Members’ Business Meeting, where the Core Research Presentations will be discussed and evaluated by NWI membership.
For the Core Research Presentations & Reviews portion of the IAB meeting, students engaged in the NWI program must prepare:
A written semi-annual research report
