Abstract A finely woven, shrinkable fabric of square-weave pattern suitable for use in the covering of aircraft frames. The fabric is formed entirely from high tenacity polyester filaments, preferably of 70-denier size. When so formed, it is significantly superior in properties of strength and elongation under load to fabrics made from regular tenacity, 70-denier polyester filaments. Such 70-denier fabrics made from regular tenacity polyester filaments do not meet the FAA requirements for aircraft cover utility, however. Consequently, although regular tenacity polyester filament fabrics have heretofore been used for aircraft cover purposes, in order to meet FAA requirements for such usage they have had to be substantially coarser and heavier than the high tenacity, 70-denier fabric of this invention.
A balanced weave greige fabric formed from high tenacity polyester filaments particularly suitable for use as an aircarft cover fabric, said filaments being of from about 40- to about 150- denier size and said fabric having a thread count from about 70 to about 100 threads per inch, warp and filling, and a weight no greater than about 3 ounces per square yard.
