Natural and artificial weathering of automotive leather, leatherette and textile 2019-28-0091
This paper presents the natural and artificial weathering behavior of leather, leatherette and textiles used for automotive seat applications. The objective of this study was to understand the UV resistance under periodic intervals and to understand the natural to artificial weathering correlation. The natural weathering under glass exposure was carried out as per ASTM G 24 and artificial weathering as per SAE J2412. The material was observed for color retention, texture retention, flexibility retention and any other changes in the construction. The natural weathering data for every 15 days were recorded, and artificial weathering for every 150 hours were recorded. Light and dark color materials were tested to understand the effect of color and UV light resistance as well as various textures were studied to understand the effect of various texture and texture retention under UV.
The study was also carried out at two different period in a year and the data were recorded. The weathering of leather, leatherette and textiles exposed at different time showed different degradation behavior. Further the UV resistance of leatherette was found better than leather and textiles. Thermal characterization DSC, FTIR, and TGA were carried out before and after weathering. The effect UV on leather, leatherette and textiles under natural and artificial weathering condition were correlated.
