Influence of UV aging on some rheological properties of footwear leather

Polimery 2019, No 9, 617


DOI: dx.doi.org/10.14314/polimery.2019.9.7

Summary

In this paper authors described rate of aging behavior processes for upper leather materials, which were measured by changes of rheological properties during determination of extension set. Upper leather samples were exposed to UV rays for 100 and 150 hours in Q-SUN XenonTest Chamber, which was used to induce property changes associated with the effects of sunlight. Then, the samples have been subjected to mechanical test –determination of extension set due to PN-EN ISO 17236:2005 standard. The main goal of this analysis was to determine of UV aging resistance of these materials. The highest resistance was observed for full grain bovine leather and nubuck as the opposition to box calfs.
