PVC (polyvinylchloride) synthetic leather or called leatherette is being widely used for automotive interior applications for seat cover, gear boot, gap hider, steering wheel and roof liner due to their leather like feel and texture, flexibility, sewability, affordability, and wide design freedom. However, the leatherette construction such as top coating, backing fabric and fabric weaving pattern plays a critical role in the finished leatherette performance for the specific application. This study provides the influence of different coating material and different backing fabric in squeak behavior of gear boot PVC leatherette. The squeak behavior was studied by stick slip test as per automotive engineering requirements, and the response of these coating and fabric surface was measured in the form of Risk Priority Number (RPN).

E-mobility is creating more challenges and great opportunities for automotive textile industries to bring out new textiles for light weight, more aesthetic, better feel, sustainable and biomaterial to meet the customer perception. Textiles allows a more design freedom to in terms of construction, weaving and wrapping solutions. A hard rough plastic surface could be transferred into a more pleasant soft touch surface by a simple wrapping with textiles. The introduction of electric vehicle will convert the car as more silent as it replaces the engine by motor and battery mechanism. The more silent is the car, the more silent is the BSR behavior of the material. This work discloses of a polyester textile developed to meet automotive lightweight to strength requirements with its new nonwoven construction for seat insert and bolster application which demands for high breaking strength, abrasion resistance, stretch and set and soiling resistance.

This paper presents the natural and artificial weathering behavior of different soft skin materials such as leather, leatherette and textiles used for automotive seat cover applications. The objective of this study was to understand the physical and aesthetical changes occurring at these flexible materials under sun UV light and heat exposure. The natural weathering study under glass exposure was carried out as per ASTM G 24 at natural weathering site location and artificial weathering as per SAE J2412 at lab. The material was observed for surface changes such as color, texture, crack and physical changes like flexibility and hardness during the exposure. The sample exposed at natural weathering data for every 15 days were recorded, and artificial weathering for every 100 hours were recorded.
