Functionalized nonwovens, method for production and use thereof

摘要

Functionalized nonwovens having a negative zeta potential in the pH range from 1 to 13 include fibers having a surface layer or surface regions applied by plasma treatment having anionic groups covalently bonded to the fiber surface and/or having precursors convertible into anionic groups and/or having polyether groups and/or polyol groups. The nonwovens may be used as filter materials or separation materials.
