UTNRL News
September 2009
UTNRL is proud to
announce the addition of nano-fiber melt blowing capabilities to the
Six Inch Melt Blowing line. Nanofiber melt blown webs were produced
in August 2009 using a spinneret incorporating technology developed
by Nonwovens Technology Incorporated and manufactured by the Arthur
G. Russell Company. UTNRL faculty and staff produced nonwoven webs
of PP, PET and PBT with average fiber diameters less than a half
micron. Research is ongoing to optimize the die design as well as
process conditions to achieve even smaller fibers and tighter
diameter distribution from a variety of resins. More details will be
provided by UTNRL Director Dr. Gajanan Bhat in the Filtration Session
at the INTC
Conference in Denver CO on Thursday, Sept 24. UTNRL
will be present at the tabletop session of INTC on Wednesday, Sept
23. Feel free to stop by and see more details and see melt blown
nanofiber samples.
UTNRL is currently
scheduling line time on the Arthur G. Russell nano fiber melt blowing
spinneret. For more information contact Dr. Gajanan Bhat
(gbhat@utk.edu
) +1(865)974-0976.
Melt blown PBT (Ticona Celanex 2008), average fiber diameter 456
nanometers, standard deviation 0.157.
