A moisture vapor permeable, water impermeable composite sheet material is provided which is suitable for use as a housewrap material, and is also useful for other applications such as tarpaulins, or as covers for automobile, boats, patio furniture or the like. The composite sheet material includes a nonwoven substrate and an extrusion-coated polyolefin film layer overlying one surface of the substrate. The nonwoven substrate is comprised of polymeric fibers randomly disposed and bonded to one another to form a high tenacity nonwoven web. The nonwoven substrate has a grab tensile strength of at least 178 Newtons (40 pounds) in at least one of the machine direction (MD) or the cross-machine direction (CD). The extrusion coated polyolefin film layer is intimately bonded to the nonwoven substrate. The film layer has micropores formed therein to impart to the composite sheet material a moisture vapor transmission rate (MVTR) of at least 35 g/m.sup.2/24 hr. at 50% relative humidity and 23° C. and a hydrostatic head of at least 55 cm. In one embodiment, the nonwoven substrate comprises a spunbonded nonwoven fabric formed of randomly disposed substantially continuous polypropylene filaments. The spunbonded nonwoven fabric is an area bonded fabric in which the filaments are bonded to one another throughout the fabric at locations where the randomly disposed filaments overlie or cross one another.

Nonwoven fabrics having liquid barrier properties are provided. The nonwoven fabrics may include one or more nonwoven layers, in which one or more of the nonwoven layers may include a liquid-barrier-enhancing-additive (LBEA) comprising an amide. The nonwoven fabrics may be suitable for use in a wide variety of liquid barrier applications, including facemasks, surgical gowns, surgical drapes, lab coats, and barrier components of absorbent articles (e.g., barrier leg cuffs).

A medical protective clothing fabric includes a Teflon fabric and a petrochemical synthetic filament fabric bonded to the Teflon fabric, where the Teflon fabric and petrochemical synthetic filament fabric are heated and bonded together with high frequency and high pressure, and the fabric hole density of the Teflon fabric is 0.05 μm to 0.1 μm. Whereby, the infectious substances can be prevented from penetrating through the Teflon fabric, and since the Teflon fabric has high temperature resistance, it is not easy to melt, deform or break in a high temperature environment. With the bonding processed with high frequency and high pressure, the processing is simple, the processing cost is significantly reduced, pinholes can further be prevented from being produced, and infectious substance is prevented from penetrating through pinholes. Furthermore, the petrochemical synthetic filament fabric improving wearing comfort allows the medical protective clothing fabric to be waterproof and air permeable.
