Abstract
A meltblown web having meltblown fibers and particles is provided. The particles are embedded in and retained by one or more meltblown fibers as a result of surface penetration of the particles into one or more meltblown fibers. The surface penetration of any particle into one or more meltblown fibers is generally slight thus leaving a substantial amount of the surface area of any particle available for interaction with any medium to which the web is exposed.
