Patent ID: 7063917

Claim:
A laminate nonwoven material comprising: a first layer formed of meltblown nonwoven fibers defining a first surface of the laminate; a second layer formed of meltblown nonwoven fibers defining the opposite surface of the laminate; and an intermediate third layer of wetlaid nonwoven fibers located between said first and second layers, the layers and bonded to said first and second layers to form a laminate, said third layer produced from a blend of hydrophobic and hydrophilic fibers; at least one of said first and third layers comprising permanently hydrophilic fibers formed of a normally hydrophobic polypropylene polymer having a hydrophilic melt additive which are melt blended therein, so as to produce a web that is able to maintain its ability to stay wet after two three-hour exposures intervals at 31% KOH at 60 degree C.
