摘要： A nonwoven material having a laminated construction and including a first layer of nonwoven fibers defining a first surface of the material; a second layer of nonwoven fibers defining the opposite surface of the material; and a third layer of nonwoven fibers located between the first and second layers. The layers are bonded together to form a laminate. At least one of the nonwoven layers comprises a nonwoven web of meltblown fibers. Additionally, one or more of the layers has been rendered permanently hydrophilic by forming the nonwoven web from meltspun fibers of a normally hydrophobic polymer having a hydrophilic melt additive incorporated therein.
