Abstract

In the development of sails sail clothes have a big importance. Present applications on sail clothes include techniques based on yarn, finishing and lamination. In this project a sail cloth has special construction can benefit from acting effect of winds even at low speed will be developed as a woven fabric. The surface of fabric which clutch the wind successfully will be designed inspiring by the tubercle structure of humpback whale fin. Wavy surface is the aim of design. In this way the frictional area increased and the wind gains a suitable precession. With this precession the suction effect of flow for movement increases. Herewith the minimum spacing on Beaufort Scale for the acting of sails can be reduced to 3.5-4 knots from 4-6 knots. The project aims to provide the basic properties of sailcloth such as UV resistance and sea water resistance using high tenacity polyester yarn as well.
