Abstract
A woven sailcloth has groups of load-bearing yarns which extend in straight lines through tunnels without being woven. The tunnels are bordered front and back by woven layers and at the sides by crossing-over yarns. Because the load-bearing yarns extend along the tunnels there is no crimp in their longitudinal direction. The load-bearing yarns may include components for resistance to displacement along the tunnels, such as resin adhesives or wrapped-around filament.
Claims24
A sailcloth comprising:
- a first woven layer,
- a second woven layer, wherein said first and second woven layers are interconnected and form parallel tunnels, and
- load-bearing yarns extending through the tunnels, in which there is at least one load-bearing yarn per tunnel for a plurality of said tunnels.

A method of manufacturing a sailcloth comprising a first woven layer, a second woven layer, in which said first and second woven layers are interconnected to form parallel tunnels, and load-bearing yarns extending through the tunnels, the method comprising weaving the yarns according to one or more of the following parameters to achieve desired cloth strength characteristics:
- number of tunnels per unit length,
- number of load-bearing yarns per tunnel,
- number of yarns per tunnel,
- yarn strength per unit length in said first and second layers, and
- tenacity of the load bearing yarns.
