Filter articles with fluoropolymer knitted fabrics |
| abstract |
The present invention discloses a filter article comprising a first layer comprising porous PTFE (eg, PTFE membrane) for fluid filtration and a second layer comprising a fluoropolymer fiber strand containing The fluoropolymer fiber strands are arranged to form a stable knitted fabric. The knitted layer includes interlocking regions, each interlocking region being defined by a corresponding set of at least two interlocking loop portions of the fluoropolymer fiber strands. In filter article embodiments, the fluoropolymer fiber strands may be twisted and/or have a rounded outer configuration. The knitted layer provides improved dimensional stability as a support layer and/or drainage layer for the filter layer. |
