Durable melt-blown particle-loaded sheet material

摘要

A permeable sheet material comprised of particle-loaded, melt-blown fiber web having a plurality of reinforcing fibers extending therethrough is provided. The reinforcing fibers 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 dispersed in the layer of melt-blown fibers 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.
