Nonwoven fibrous webs including a multiplicity of randomly oriented discrete fibers and a multiplicity of chemically active particulates secured to the web, and methods of making and using same. In some embodiments, more than 0% and less than 10% wt. of the nonwoven fibrous web is made of multi-component fibers having at least a first region exhibiting a first melting temperature and a second region exhibiting a second melting temperature greater than the first melting temperature. In other embodiments, the discrete fibers include a first population of monocomponent thermoplastic fibers having a first melting temperature, and a second population of monocomponent fibers having a second melting temperature greater than the first melting temperature. In certain embodiments, at least some of the particulates are bonded to the fibers. In other embodiments, at least some of the particulates are secured within interstices of the fibrous web, without substantial bonding to the fibers. |
