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. 本文描述了一种可透过的非织造纤维网，其具有第一聚合物基体的多根纤维和/或长丝，所述第一聚合物基体形成所述多根纤维和/或长丝中每一根的外表面。所述第一聚合物基体包含共混于其中的亲水性熔体添加剂和/或触觉改性熔体添加剂。横跨整个所述纤维网或其部分的能量施加促进所述熔体添加剂从所述第一聚合物基体的起霜，使得起霜区域设置在所述纤维和/或长丝的外表面中的每一者的至少一部分上。
