    Abstract: In at least one embodiment, a membrane filtration element is provided. The element may include at least one feed spacer including a first set of parallel strands extending in a first direction and including a plurality of first strands having a first thickness and a plurality of second strands having a second thickness that is smaller than the first thickness. A second set of parallel strands may extend in a second direction that is transverse to the first direction. The second set of parallel strands may include a plurality of third strands having a third thickness and a plurality of fourth strands having a fourth thickness that is smaller than the third thickness. In one embodiment, the first and second sets of strands include alternating thick and thin strands, which reduce pressure drop in membrane filtration systems.

    Abstract: A polymeric netting includes polymeric strands and first and second polymeric ribbons. The first and second ribbons each independently have a height-to-width aspect ratio of at least three to one and a major surface that is intermittently bonded to a polymeric strand, with first and second edges symmetrically disposed on opposite sides of a center line bisecting the major surface. The netting has first and second opposing major surfaces transverse to the major surfaces of the first and second ribbons. The first major surface of the netting includes the first edges of the first ribbons, and the second major surface includes the second edges of the second ribbons. The first ribbons do not extend to the second major surface, and the second ribbons do not extend to the first major surface. Articles including the netting, an extrusion die, and a method useful for making the netting are also disclosed.

    Abstract: Method and extrusion die (1030) for producing a three-dimensional polymeric strand netting, wherein a plurality of the polymeric strands (1070a, 1070b, 1070c) are periodically joined together in a regular pattern at bond regions throughout the array, wherein a majority of the polymeric strands (1070a, 1070b, 1070c) are periodically bonded to at least two (three, four, five, six, or more) adjacent polymeric strands, and wherein no polymeric strands are continuously bonded to a polymeric strand. Three-dimensional polymeric strand netting described herein have a variety of uses, including wound care, tapes, filtration, absorbent articles, pest control articles, geotextile applications, water/vapor management in clothing, reinforcement for nonwoven articles, self bulking articles, floor coverings, grip supports, athletic articles, and pattern coated adhesives.
