摘要： A method of preparing a sterilized nonwoven web, which method includes providing a nonwoven web; coating the nonwoven web with from about 0.005 to about 3 percent by weight, based on the weight of the web, of an antistatic agent; and exposing the coated nonwoven web to an oxidizing gas plasma. The antistatic agent is adapted to be free of a malodor after exposure of the coated nonwoven web to the oxidizing gas plasma. The antistatic agent may be further adapted to provide a sterilized nonwoven web having a hydrohead value as measured by Method 5514 of Federal Test Method Standard No. 191A which is at least 50 percent of the hydrohead value of the coated nonwoven web before exposure to the oxidizing gas plasma. The antistatic agent also may be adapted to provide a sterilized nonwoven web having a surface resistivity in ohms which is lower than the surface resistivity in ohms of the coated nonwoven web before exposure of the coated nonwoven web to the oxidizing gas plasma. The antistatic agent may be an alkali metal or ammonium salt of either a mono- or di-C3-alkyl phosphate in which the C3-alkyl moiety is an alkyl group containing three carbon atoms optionally substituted with hydroxy groups or a &bgr;-carbon substituted alkyl phosphate, a di(&bgr;-carbon substituted alkyl) phosphate, or a mixture of two or more of the foregoing. The invention also provides a fibrous sheet-like material, such as a barrier fabric, a sterilization wrap, a surgical garment, and medical procedure packs.

摘要： The present disclosure is directed to a method of forming a treated fiber. A molten polymer is delivered to a fiber spinning assembly adapted to form and distribute polymer streams. At least one treatment is applied in a liquid state to at least one region on the surface of at least one molten polymer stream within the fiber spinning assembly. A substantial portion of the treatment remains on the surface of the resulting fiber within the treated region. One or more regions on the surface of the molten polymer may be treated with one or multiple treatments. The degree of coverage may vary from little coverage to complete coverage of the fiber surface. The treated regions may be in contact with one another or may be separate and distinct. A nonwoven web may be produced with selectively treated fiber regions by designing one or more fiber spinning assemblies to treat selected fibers or to apply multiple treatments. The regions of the nonwoven web may vary in treatment type, amount, or degree of coverage.
