Abstract
A tent fabric constructed substantially of woven polyethylenenaphthalatebibenzoate (PENBB) yarns. The PENBB yarns of the fabric exhibit very low tenacity loss resulting from UV degradation, and exhibit very good dimensional stability, very low hot air shrinkage and very low creep. A flame retardant polymer may be added to the PENBB polymer before extrusion to provide flame resistance.
