    摘要: A fire blocking non-woven textile containing a first carded web of char-forming fibers containing aramid or melamine/formaldehyde fiber and a second carded web of oxygen-depleting fibers comprising a blend of polyacrylonitrile copolymer with a halogen comonomer and a polyester polymer. The webs may be needled-punched or thermally bonded and remain as separate layers separating the action of the char forming and oxygen depleting layers to optimize char strength, provide a light weight product, which may satisfy 16 CFR 1633 at thicknesses of up to 3.0 mm.
