In order to investigate the changes of knitted fabric properties due to exposure to outdoor natural weathering, a series of single jersey fabrics made from different raw materials was produced. The fabrics were exposed to summer weather conditions in duration of three months. The exposure of knitted fabrics to outdoor natural weathering in the summer period affected all investigated properties, namely, structural properties, tensile properties and heat resistance. The most significant changes were: the vertical density increased up to 31%, the mass per unit area increased up to 26%, the breaking force decreased in both directions for up to 54% and the heat resistance decreased up to 18%.
