  • Patent number: 10464001
    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.

  • Patent number: 10457456
    Abstract: A gas barrier sheet material which make effective use of natural resources and which has improved gas barrier properties including oxygen barrier properties, water vapor barrier properties and smell barrier properties, and improved flexibility; a barrier container using the same; and a method for fabricating a sheet material. A sheet material is characterized in that a fine fiber layer and a moisture-retaining layer are stacked on at least one surface of a substrate in such a way that the fine fiber layer and the moisture-retaining layer are in direct contact with each other. The invention is more advantageous when using a substrate, e.g. paper, a nonwoven fabric, or a porous membrane, of which surface profile is not flat and which is inherently susceptible to causing troubles in fabrication processes, such as of soaking, wetting and drying during coating of a coating agent.

  • Patent number: 10328661
    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.
