Definitions

  • FIG. 3 is partial cut-away perspective view of a filter system including a nonwoven fabric shown in FIG. 1.
  • FIG. 4 is a perspective view of a reverse osmosis membrane filter including a nonwoven fabric shown in FIG. 1.
  • nonwoven fabric can then be cut to a particular size (having a distinct length and width) and the continuous fiber would generally have a length equal to or greater than the length or width of the non- woven fabric.
  • a staple fiber refers to a fiber shortened prior to being incorporated into a fabric and therefore has a distinct length independent of and different from the length or width of the fabric.
  • spunbonded fiber refers to a fiber that has been extruded, drawn, and laid on a moving substrate (e.g., a move belt).
  • non- woven fabric 10 has a planar structure that is relatively flexible and porous.
  • bubble point refers to the largest pore size in a one-square-inch (i.e., about 6.45 cm 2 ) sample measured by Capillary Flow Porometer CFP 1200 AEX available from Porous Materials, Inc.
