Dacron is the brand name of Dupont’s Type 52 high modulus fiber made specifically for sailcloth. Allied Signal has produced a fiber called 1W70 polyester that has a 27% higher tenacity than Dacron. Other trade names include Terylene, Tetoron, Trevira and Diolen.
Sailcloth is typically made from PET fibers also known as polyester or under the brand name Dacron; colorful lightweight spinnakers are usually made of nylon. PET in its most stable state is a colorless, semi-crystalline resin. However it is intrinsically slow to crystallize compared to other semicrystalline polymers.

Hang glider sailcloth is normally made from woven or laminated fiber, such as dacron or mylar, respectively. Woven polyester sailcloth is a very tight weave of small diameter polyester fibers that has been stabilized by the hot-press impregnation of a polyester resin. The resin impregnation is required to provide resistance to distortion and ...
Sails may be made from a combination of woven materials—including canvas or polyester cloth, laminated membranes or bonded filaments, usually in a three- or four-sided shape. A sail provides propulsive force via a combination of lift and drag, depending on its angle of attack , its angle with respect to the apparent wind .
North Sails introduced the 3DL line of upwind sails in 1992. In the 3DL manufacturing process, aramid or carbon fiber yarns and layers of polyester film are laid over a computer-controlled mold that is configured to assume the airfoil shape of the sail, and then thermo-formed to produce a laminated sail with the intended three-dimensional shape.
