Breathable barrier composite with hydrophobic cellulosic fibers

摘要

A breathable barrier composite of cellulosic fibers includes a compressed mixture of hydrophobic cellulosic fibers and thermally-bondable polyolefin fibers. The composite has a combination of high liquid barrier properties, and high air and moisture vapor porosity. The composite also has a very soft and cottony texture. The breathable barrier composite may optionally contain a nonwoven layer, such as a spunbond or an SMS nonwoven, a polyolefin film layer, or a nonwoven wipe layer.
