摘要：A nonwoven web or laminate having improved antistatic properties and alcohol repellency properties is generally provided, along with methods of making the same. The method includes forming a nonwoven web from a thermoplastic mixture of an antistatic agent and a thermoplastic polymer. A high energy treatment is applied to a surface of the nonwoven web. Then, a fluorinated agent is grafted to the surface of the spunbond web utilizing a monomer deposition process. The monomer deposition process can generally include evaporating a liquid fluorinated agent in a vacuum chamber, followed by depositing the fluorinated agent gas on a surface of the spunbond web, and exposing the surface to radiation.
