摘要： The nonwoven composite fabric of the invention provides a barrier to blood and viral challenges, and also provides breathability for comfort. The fabric is particularly suited for use as a disposable surgical gown. The fabric comprises a first microporous ply comprising a microporous formable resin that has been extrusion coated onto a nonwoven fabric substrate and subsequently stretched to impart microporosity, and at least one additional ply positioned adjacent the first microporous ply. The nonwoven composite fabric has barrier properties passing the ASTM F1671 viral barrier test, and the MVTR of the composite fabric is at least 300 g/m /24hr.

Preferably, the apertured cut-resistant material (22) is in the form of sheet having a thickness of between about 0.005 inches and about 0.020 inches, and has an open area of less than about 50 percent. It is also preferred that the cut-resistant sheet (20) have fold lines formed on a non-cutting surface, so as to make the material easily foldable and/or tearable. In addition, a stainable absorbent cover layer can be attached to a cutting surface of the cut-resistant sheet (20) to provide an indication of where cutting has occurred, and to give the material a desirable appearance. A liquid impervious backing layer is also preferably attached to the absorbent material (24) to resist the escape of fluid from the absorbent material. It is preferred that the cut-resistant sheet (20) comprises a polymeric material.

摘要： Microporous material comprising a polypropylene polymer having at least 20 percent crystallinity; and a compatible, amorphous, glassy polymer, wherein said polymers are miscible in a compound when heated above the melting temperature of the polypropylene polymer and wherein a polypropylene polymer phase separates from the compound when cooled below the crystallization temperature of the polypropylene polymer. Microporous material is made by a thermally induced phase separation process using a compound such as mineral oil to form one phase containing both polymers. The pores of the microporous material resist collapse during processing. Membranes made of this material are useful as battery separators having a good combination of strength, porosity, and ionic resistance when imbibed with an electrolyte.

摘要： A layered structure (44) that includes a product mixture of numerous particles, a foamable substance, such as including a liquid binder and a reacted dry binder, is provided. The particles preferably are comprised of cellulosic, fibrous materials. The dry binder reacts with the liquid binder to create a strong bond among separated particles. The particles are separated during transport, together with the dry binder, before the dry binder is reacted with the foamed liquid binder. Upon contact with the liquid binder, the dry binder reacts to cause adhesion among the separated particles. The layered structure (44) also includes one or more outer members or panels that are laminated or otherwise joined to the outer surface portions of the product mixture. Packaging materials can be made from such a layered structure (44). Additionally, wall units, panels, dividers and other enclosures or supporting units can be configured from one or more of such layered structures (44).

摘要： A flame retardant, electrically-conductive EMI shielding material and method, the material being particularly adapted for use in fabric-over-foam EMI shielding gasket constructions. In construction, a generally planar, porous fabric member is provided as having at least an electrically-conductive first side and a second side defining a thickness dimension therebetween. A curable layer of a fluent, flame retardant composition is applied under a predetermined hydrodynamic pressure and viscosity to at least a portion of the second side of the fabric member. The hydrodynamic pressure and viscosity of the composition are controlled to delimit the penetration of the layer into the fabric member to a depth which is less than the thickness dimension of said fabric member. The layer then is cured to form a flame retardant surface coating on the second side of the fabric member such that the first side of said fabric member remains electrically-conductive.
