Abstract
Traditional parachute fabrics are composed from PA 66 (nylon type) multifilament yarns. They are resistant against high frequency repeat deformation but they are able to absorb water which is not optimal for use in different climatic conditions. Challenge is to create parachute fabrics made of PES multifilament yarns which are more versatile. Main aim of this work is to investigate influence of parachute fabric composition and construction characteristics on real end use properties. The relationships based on the prediction of bulk densities were used to calculate the volume porosity. The morphology of the parachute fabrics was evaluated using scanning electron microscopy. Mechanical and dynamic mechanical properties of parachute fabric Ortex made from multifilament PA 66 and PES yarns by Sky Paragliders company are compared.
