Definitions

  • the present disclosure relates to a fabric, and more particularly to a fluoropolymer- containing fabric having improved strength retention.
  • Fabrics such as architectural fabrics, can be subjected to high tension and repeated flexing.
  • an architectural fabric can be used in a building structure or as part of a building structure to provide protection from environmental elements such as wind, sun, and rain.
  • Such fabrics have long been used in tents, where ropes and poles provide tension to allow the fabric to withstand loads.
