Abstract: A method of making a fluorinated fibrous web, which method includes providing a nonwoven web 22 that contains polymeric fibers, creating a plasma that contains fluorine atoms at a first location 14, and contacting the nonwoven web with products from the plasma at a second location 26 remote from the first location 14. The method avoids exposure of the web to the plasma and hence expands the manufacturing processing window. Webs so fluorinated have a different C3F4H+ to C2F5+ ratio when compared to locally fluorinated webs having similar levels of surface fluorination. The remote fluorinated webs can be subsequently charged electrically to provide a good performing electret filter 40 suitable for use in an air purifying respirator 30. Webs fluorinated in accordance with this invention also may exhibit good performance even after being “aged” at high temperatures.

Abstract: Asymmetric expanded polytetrafluoroethylene (ePTFE) membranes that contain multiple layers of ePTFE where at least one layer of ePTFE has a microstructure different from the microstructure of a second ePTFE layer. In exemplary embodiments, the asymmetric membrane contains a first ePTFE layer that has an “open” microstructure and a second ePTFE layer that has a less open, or “tight” microstructure. A third ePTFE layer having an “open” microstructure may be positioned on the second ePTFE layer. The asymmetric membranes possess print durability and are both abrasion resistant and air permeable. Additionally, printed asymmetric ePTFE membranes demonstrate low gloss. A textile may be affixed to the asymmetric membrane such that the first ePTFE layer is the outer surface of the laminate. Laminates containing the asymmetric membrane are sufficiently durable against abrasion so that articles of apparel having an exterior film surface remain liquid proof after an abrasion challenge.
