发明名称 PAPER WEB HAVING A LIQUID IMPERMEABLE, BREATHABLE BARRIER LAYER
摘要 <p>A multiple ply paper web (10) comprising at least one outer cellulosic ply (30), preferably two outer cellulosic plies (30) passively bonded to at least one inner ply (20). The inner ply can be comprised of meltblown fibers formed into a liquid-impermeable, breathable nonwoven web. The tissue plies can be creped tissue paper having a basis weight of from about 10 g/m2 to about 100 g/m2, preferably from about 15 g/m2 to about 25g/m2. In a preferred embodiment, the meltblown fibers of the inner ply comprise polypropylene fibers having an average diameter of less than about 10 microns, and more preferably less than about 2.5 microns. The nonwoven web can have a basis weight from about 1 g/m2 to about 15 g/m2, preferably from about 1 g/m2 to about 10 g/m2, and more preferably from about 1 g/m2 to about 8 g/m2. In a preferred embodiment the inner ply has a Moisture Vapor Transmission Rate of at least about 4000, and can hold a hydrostatic head of at least about 20 mm H¿2?O.</p>
