Abstract
Abstract 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 m 2 per liter, the fibers in the fibrous structure being thermally bonded to at least one other fiber.

A fuel tank for a vehicle containing therein a flame arrestor, said flame arrestor, comprising a thermally bonded, non-woven fibrous structure formed from fibers comprising potentially adhesive conjugate fibers in which the components extend along the length of the fiber, one of the components having a lower softening temperature than the other components and forms at least part of the peripheral surface of the fiber wherein the non-woven fibrous structure is formed from fibers comprising at least 90% of potentially adhesive conjugate fibers having a decitex in 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 m 2 per liter, the fibers in the fibrous structure being thermally bonded to at least one other fiber.
