13 NWI Student Researchers to Present Posters at 2023 RISE® Conference
Providing students with the opportunity for exposure to both excellent academics and industry professionals is one of the greatly appreciated characteristics of The Nonwovens Institute (NWI). During the Institute’s 2020 5-year Review, several students interviewed by the review team commented upon the strength of the faculty associated with NWI and the linkage between industrial members of the Institute and their research work. Students commented that “NWI offers us an opportunity to work with ‘real world’ experts and technical leaders to a far greater degree than our peers.”
At the upcoming RISE® conference to be held on the NC State campus September 26-27 students will again have the unique opportunity to interact with some of the most innovative minds in the field of engineered fabrics. Thirteen students will be presenting their work in a poster session from 5:00–7:00 pm at the Lonnie Poole Golf Club on the campus of NC State, offering conference attendees and students alike a forum for interacting and discussing their work. These students represent a variety of research interests and come from a number of different schools and departments across the university; highlighting NWI’s multidisciplinary foundation. Each of the students not only studies under outstanding members of the NC State University faculty, but is also mentored during their studies by at least one representative from NWI member companies.
The RISE® conference, organized by INDA – the Association of the Nonwoven Fabrics Industry, is in its 13th edition. INDA serves hundreds of member companies in the nonwovens / engineered fabrics industry doing business globally. Since 1968, INDA networking events have helped members connect, innovate and develop their businesses. INDA educational courses, market data, test methods, consultancy and issue advocacy help members succeed by providing them the information they need to better plan and execute their business strategies. INDA Media is the business-to-business publishing arm of INDA and publisher of International Fiber Journal and International Filtration News, which reach a vast network of professionals who employ fibers, filaments, and filtration systems to optimize their application environments.

Morgan Gilbert – “Hydroentangled Cellulosic Nonwovens as Potential Reusable and Biodegradable Fabrics”
Morgan is investigating the impact that hydroentangling energy has on cellulosic nonwovens and their ability to withstand repeated laundering. Morgan completed her master’s degree at NC State this summer and is now moving into the Fiber and Polymer Science Ph.D. program in the Wilson College of Textiles, Department of Textile Engineering Chemistry and Science. She is a 2023-24 co-leader for the NWI Student Group and receives academic advisorship from Dr. Pourdeyhimi.
Nishant Bhatta – “Flow-less Coalescence Filtration Experiment: A Novel Approach to Study Instantaneous Saturation in Nonwovens”
Nishant is a student of Associate Professor Hooman V. Tafreshi, Ph.D., in the College of Engineering, Department of Mechanical and Aerospace Engineering. His work studies the role of nonwoven’s microstructure in promoting/preventing fluid transport, development of relationships for the wetting saturation of a nonwoven in terms of its microstructural properties and developing predictive relationships for the performance of coalescing filters. Nishant previously presented at RISE® 2022.
Shajid Rahman – “Modeling Compression-Recovery in Multicomponent Nonwovens – A Design Tool”
Shajid is a student of Dr. Tafreshi, in the College of Engineering, Department of Mechanical and Aerospace Engineering. His work aims to develop a microscale force-network model that can simulate propagation of normal and tangential stresses through fiber–fiber contact in a 3-D fibrous structure. This work explores the compression–recovery dynamics of a nonwoven fabric to develop relationships between compression and nonwoven microstructures.
Shyam Atri – “Computational Experimental Study on Particle Removal via Electrically Charged Multilayer Nonwovens”
Shyam studies in the Department of Mechanical and Aerospace Engineering and is a student of Dr. Tafreshi and Dr. Pourdeyhimi. Shyam’s research relates to computational and experimental studies of filtration/particle removal via electrically charged multilayer nonwovens.
