Fire protection means comprising a non-woven fibrous structure of thermally bonded conjugate fibers

摘要

A fuel tank for a vehicle contains therein a flame arrestor comprising a thermally bonded, non-woven fibrous structure formed from fibers comprising at least 90% potentially adhesive conjugate fibers having a decitex within the range 6 to 35, the non-woven fibrous structure having a density of not more than 16 g per liter and a surface area of at least 0.35 m2 per liter, the fibers in the fibrous structure being thermally bonded to at least one other fiber.
