Abstract
A nonwoven is formed from one or more performance enhancing fibers together with one or more cellulosic fibers. The nonwoven could include low melting fibers for holding the nonwoven together on melting, and could include one or more optional fibers which impart a characteristic of interest to the nonwoven. The cellulosic fiber in the nonwoven is treated with fire resistant chemicals. The nonwoven has enhanced fire barrier performance, such as char elongation and char strength.
