2 Claims

1. A method of forming a shield material comprising the steps of blending a plurality of heat and flame resistant fibers having a first denier with a plurality of bulking fibers having a second denier being greater than the first denier of the heat and flame resistant fibers and a plurality of binder fibers, and projecting the blended heat and flame resistant fibers, binder fibers, and the bulking fibers along a moving belt such that a unitary nonwoven material is formed on the belt with a heat and flame resistance zone and a bulking zone, whereby the heat and flame resistance zone includes a greater percentage of the heat and flame resistant fibers than the bulking fibers and the bulking zone includes a greater percentage of the bulking fibers than the heat and flame resistant fibers.
