  • Multilayer nonwovens incorporating differential cross-sections
    Patent number: 7153793
    Abstract: Nonwoven fabric fabrics suitable for undergoing pleating to form filtration media are provided. The fabrics generally include at least three layers. The fibers forming the inner layer has a cross section providing greater stiffness, while the fibers forming the outer layers have a cross section providing greater durability. The resulting fabrics provide improved particulate holding and pressure drop characteristics at no sacrifice to durability.
