Abstract
Disclosed is a support article containing a first non-woven layer and a second non-woven layer. The first non-woven layer contains a blend of fibers of about 15-70% by weight fire resistant (FR) rayon fibers, 10-30% by weight hollow conjugated siliconized fibers, and 20-40% by weight binder fibers. The second non-woven layer contains a blend of FR rayon fibers, hollow conjugated siliconized fibers, and binder fibers. The amount of FR rayon fiber is within 15 percentage points of the weight percentage of FR rayon fiber in the first non- woven layer. The lower surface of the first non-woven layer is adhered to the upper surface of the second non-woven layer. The density of the first non-woven layer is at least 10% less than the density of the second non-woven layer.
