History of Nonwovens at NC StateHistory of Nonwovens at NC State

The Nonwovens Cooperative Research Center (NCRC) was founded in 1991 as a State-IURC from grants from the United State National Science Foundation (NSF), the State of North Carolina, and Industry. NCRC Graduated from NSF in 1998.

NCRC has grown to be the largest industry cooperative research center in the Nation.

The Nonwovens Institute (NWI) was established on February 15, 2007.
