Abstract
A woven geometric textile material has a body portion having a plurality of weft strands woven with a plurality of warp strands comprising thermoplastic strands, the body portion comprising a body weave having a plurality of repeating weave patterns in a grid of patterns, each weave pattern including at least 44 body warp strands and at least 44 weft strands and the body portion having a solid fraction of less than 3 percent. A separator media comprising the textile material and a separator device employing the separator media are disclosed. A loom for making the textile material and method of making the textile material is disclosed.
