Abstract
The warp and weft yarns are woven either conventionally, one over the other, or with certain reinforcing yarns being woven over several yarns. The majority of the warp and weft yarns have a tensile modulus of 100 grams/denier or less. The reinforcing yarns have a tensile modulus of 500 grams per denier or greater. The majority comprise Dacron type polyester yarns. The reinforcing yarns (every 5th-100th) are Kevlar or Spectra.
Claims12
An improved sailcloth comprising a single non-laminated ply, said ply having woven warp and weft yarns, a majority of said warp and weft yarns having a tensile modulus in the range of 20-100 grams per denier, every Nth warp yarn being a reinforcing yarn having a tensile modulus above 500 grams per denier.
An improved sailcloth comprising a single non-laminated ply, said ply having woven warp and weft years, a majority of said warp and weft yarns having a tensile modulus in the range of 20-100 grams per denier, a minority of weft yarns having a tensile modulus above 500 grams per denier to act as reinforcing yarns in a direction generally perpendicular that of said warp yarns.
