Lightweight nonwoven fire retardant barrier
A non-woven flame retardant barrier can be prepared from low denier, charring fibers and substantially free of polymers made from halogenated monomers. The charring fibers can be modified viscose fibers, for example Visil®. The blend of low denier fibers can be, for example, a blend of 1.5 denier fibers and 3.0 denier fibers.

2. An article comprising the non-woven of claim 1 , wherein the article meets an industry standard for mattress flammability.
3. The article of claim 2 , wherein the article is a mattress.
4. The non-woven of claim 1 , wherein the modified viscose fibers comprise Visil®.
5. The non-woven of claim 1 , wherein the modified viscose fibers have a denier of about 3.0.
