Abstract (en)
[origin: EP0257868A2] A durable fibrous sheet material comprised of a melt-blown fiber web having a plurality of reinforcing fibers extending therethrough is provided. The reinforcing fiber are needled through the web of melt-blown fibers and are then bonded to fibers on the opposing faces of the layer of melt-blown fibers to hold the reinforcing fibers in position. Solid particles can be dispersed in the layer of melt-blown fibers. Such particles are preferably vapor-sorptive particles, e.g., activated carbon, so that the sheet material will sorb vapors passing therethrough. The sheet material is particularly useful as a component of a chemical protective garment.
