Sažetak
The durability testing of fishing nets is not defined by the normative regulations, nor the impacts of the usage conditions on their functionality are fully clarified. The durability evaluation of netting yarns and knotted netting made of polyamide 6 (PA6) was carried out, by investigating the influence of solar radiation and sea salt (NaCl) separately in the laboratory simulated ageing conditions ; and the combined effects of sea water, solar radiation and all atmospheric influences through simulation of real application conditions. The samples were exposed to artificial light source in a Xenotest, neutral salt spray (NSS) in a salt spray cabinet for 60 hours and in natural environment at a Croatian island Lošinj during two months, where the samples had been repeatedly immersed in seawater during the night and during the day exposed to direct solar radiation. The surface characterization of the PA6 netting samples was carried out using SEM analysis. With the aim of determination of tensile properties changes, breaking force, knot breaking force and elongation of netting yarns and mesh breaking force were examined in the dry and wet state. Results indicated that exposure of PA6 netting materials to simulated ageing in a relatively short period affecting the change of investigated properties.
