Abstract

A permeable nonwoven web having a plurality of fibers and/or filaments of a first polymer matrix forming an outer surface of each of the plurality of fibers and/or filaments is described herein. The first polymer matrix includes a hydrophilic melt additive and/or a tactile modifying melt additive blended therein. Energy application across the entirety of the web, or parts thereof, promotes the blooming of the melt additive from the first polymer matrix such that bloom areas are disposed on at least a portion of each of the outer surfaces of the fibers and/or filaments.
