Sažetak
In this work, the influence of artificial ageing on the properties of standard polyester fabrics was investigated. Since the actual test procedures are long-lasting, the natural ageing process is replaced in this work by artificial ageing in accordance with the ISO 105-B02:2013 standard. Standard polyester fabric is artificially aged under direct irradiation for 85 and 170 hours at a relative humidity of 40%. With the aim of gaining an insight into the properties of polyester fabrics during exposure to UV radiation, polyester fabrics were analysed throuhg physico-chemical, morphological-tactile and mechanical properties. The tensile properties decrease with ageing, which depends on the duration and time of exposure to irradiation. The FTIR analysis showed the possible effects of artificial ageing on aged fabrics in the wavelength range around 2900 cm-1, where oxidation of the C–H bond is most likely to occur. The photooxidative degradation of polyester fabrics starts at the surface of the fabric due to the slow diffusion of oxygen into the polymer structure, leading to changes in some physical properties, such as loss of gloss and roughness of the surface. With increasing exposure time, the breaking strength decreases, the mechanical properties become weaker and the stiffness of the fabric also decreases. It was found that the properties of the fabric in terms of its ability to manage moisture also change with different exposure times.
