Title: Chemical and Physical Properties of Synthetic Fibres Most Commonly Used in Fishing Gear, With Reference to their use in Cape Verde Fisheries.

This study deals with the following synthetic fibres: Polyamides, Polyesters, Polyethylene, Polypropylene, and Dyneema. The objective was to identify the characteristics of each of them and give basic information about these fibres with reference to their use in Cape Verde fisheries. A series of experiments was carried out about breaking strength, elongation, elasticity, resistance to abrasion and weathering, properties that are of a great importance in ensuring correct performance of a particular gear. Dyneema is the newest fibre and special attention was given to it in this study. Also the selection of synthetic materials is discussed.
