Porous packing and separator medium

A porous contacting medium characterized by

• a. a first set of monofilament yarns;
• b. each yarn of said first set being substantially straight and parallel to every other strand in the set;
• c. each yarn of said first set being spaced from every other yarn in the set both vertically and horizontally;
• d. a second set of monofilament yarns woven with said first set;
• e. each of the yarns of said second set being substantially parallel to every other yarn in the second set;
• f. said yarns in said first set being perpendicular to the yarns in said second set;
• g. said first and second sets of yarns being woven into a honeycomb pattern and comprised of a heat-shrinkable thermoplastic polymer;
• h. the lengths of each yarn of said second set extending in interleaved fashion through the yarns of said first set in a geometric orientation to accommodate the vertical and horizontal offset spacing of each yarn in said first set;
• i. each of said yarns of said second set including a plurality of straight line portions with said portions joined at angles to provide said geometric orientation;
• and
• j. said angled geometric orientation of said second set and said offset spacing of said first set giving said medium a thickness in cross section greater than the thickness thereof prior to said geometric orientation.
