Filtration Tutorial
Instructor: Norman Lifshutz, Retired, Hollingsworth & Vose Co.
Tuesday, September 13: 8:30am - 11:30am
There's no better source for technical knowledge in nonwovens than the TAPPI NETInc Conference. This Tutorial is included in your conference registration.
The Tuesday morning Filtration Tutorial will cover the Theory of Aerosol Filtration in Fibrous Webs. The nature of chaotically produced fibrous webs such as meltblown and microfiber glass will be discussed as well as the basic definitions and theory needed to understand and predict air resistance and particle capture efficiency in fibrous webs. Mathematics will be descriptive rather than rigorous, in order to provide understanding.
Dr. Norman Lifshutz was born and grew up in New York City, where he attended public schools, including The Bronx High School of Science. He took an undergraduate degree in Chemical Engineering at the Cooper Union, and did his graduate work in Chemical Engineering at Northwestern University, receiving both an MS and a PhD.
Although trained as a Chemical Engineer, he has spent most of his career as a Material Scientist. He worked ten years for Uniroyal Inc., first in Corporate R&D on fiber to rubber adhesion, and then for their Consumer Products Division in product and process development of footwear and coated fabrics. After leaving Uniroyal he became Director of R&D and QC for the Pressure Sensitive Tape Division of American Biltrite for eight years. He then was Vice President of R&D and Senior Research Fellow at Hollingsworth & Vose Co. for twenty years, where he developed products and processes in the areas of fibrous filter media, meltblown fibers, nanofibers, and battery separators. In 2007 he retired from H&V, but continues to consult for them and other clients.
He is an active member of The American Filtration and Separation Society, where he is the Treasurer, an active member of the Nonwoven Engineering and Technology Division of TAPPI where he is a past chair of the Nonwovens Division Steering Committee, and an individual member of INDA, where he is involved in the Filtration Committee. He is a Coeditor and an Area Editor of the Journal of Engineered Fibers and Fabrics, and a member of the Editorial Board of the TAPPI Journal. He has authored and presented numerous papers and he holds nine patents. He was the recipient of the 2007 TAPPI Nonwovens Division Leadership and Service Award, the 2009 TAPPI Nonwovens Division Technical Award and Mark Hollingsworth Prize, and the 2011 AFS Lifetime Achievement Award. Norman currently lives in Peoria, Arizona, with his wife Harriet. They have two children and four grandchildren.
