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 translation: 一种制造氟化纤维网的方法，该方法包括提供含有聚合物纤维的非织造纤维网22，在第一位置14产生含有氟原子的等离子体，并使第二位置26处的来自等离子体的产物接触非织造纤维网 远离第一位置14.该方法避免了将幅材暴露于等离子体，并因此扩展了制造处理窗口。 当与具有相似水平的表面氟化的局部氟化网相比时，如此氟化的网具有不同的C3F4H +至C2F5 +比。 远程氟化纤维网随后可以电连接以提供适合用于空气净化呼吸器30的性能优异的驻极体过滤器40.根据本发明氟化的网络即使在高温下“老化”之后也可能表现出良好的性能。
