Course Objectives:

Nonwovens continue to grow in production and consumption all over the world. From disposable cheap products to high-value engineered products, nonwovens find application in several areas that are critical to our life and environment, including that of filtration. Filtration and other performance of nonwovens depend on the structure and properties of the products, which in turn depend on the choice of the materials and the processes used.

This course will provide an overall understanding as to what nonwovens are and how they are different from other fabrics. The topics that will be covered include: (i) Nonwoven products and markets; (ii) Polymers and fibers used in nonwovens; (iii) Nonwoven production – web formation and Bonding; (iv) Dry-laid and Wet-laid formation of webs; (v) Direct web formation from polymers; (vi) Web bonding technologies – mechanical, thermal and chemical; (vii) Finishing of nonwovens; and (viii) Nonwovens testing and characterization. Advantages and disadvantages of these processes, as well as their flexibilities and  limitations will be deliberated.

Because of the enormous opportunities and continuing innovation, nonwoven sector continues to enjoy sustainable growth for foreseeable future. Recent innovations and developments, as well as the options available for the industry to develop new products will be discussed.

Instructor Biography

Dr. Gajanan S. Bhat

Professor @ University of Georgia

Dr. Bhat is a Georgia Athletic Association Professor of Fibers and Textiles, Head of Department of Textiles, Merchandising and Interiors ,University of Georgia, Athens, GA, USA


After earning his Ph.D. from Georgia Tech in textile and polymer engineering, Dr. Bhat joined the University of Tennessee, Knoxville (UTK) in August 1990, where his research covered nonwovens - melt blown, spunbonded and biodegradable, plastics recycling, nanotechnology, sustainable materials, and high performance fibers. As the director of UTNRL he demonstrated successful production of nanofibers from thermoplastic polymers by meltblowing. In July 2016, he joined UGA as the Head of the Textiles and Merchandising and Interiors (TMI) department. Dr. Bhat has published more than 200 research papers, has three US Patents and has made more than 250 national or international presentations. He has served as the president of the Fiber Society and is also an active member of INDA, TAPPI and the Textile Institute. Some of the awards/recognitions he has received include:


  • Outstanding Young Engineering Alumni by Georgia Tech (1996)

  • Distinguished Achievement Award from the Fiber Society (1999)

  • Fellow of the Textile Institute (2005)

  • TechniTex India Research Achievement Award (2008)

  • TAPPI NET division Technical Achievement Award (2014).

In addition to conducting research in the area of nonwovens since 1984, Dr. Bhat has taught nonwoven courses at UTK, and was involved in developing and teaching the introductory nonwovens training course with INDA. He has also been part of the nonwovens tutorial and INTC and TAPPI NET conferences. In addition to being part of the Textile and Nonwovens Development Center (TANDEC) conference for several years, he has served as session chair and organizing committee member of  several TAPPI and INDA technical conferences.  Many of his former students are working in reputed nonwoven companies as well. He has been working with many nonwoven companies in product development and solving problems.
