Automotive interior materials are a crucial component of the vehicle's interior. Their primary function is to enhance the aesthetics of the cabin. Simultaneously, automotive interior fabrics can improve insulation against external cold and heat; reduce interior noise and improve sound absorption; and enhance passenger comfort and safety.
Because a car is a small, enclosed space, the interior must be environmentally friendly, non-toxic, and odorless to ensure a pleasant experience for passengers. The non-woven felt used in automotive interiors is processed with environmentally friendly adhesives, resulting in a strong bond, resistance to delamination, and water resistance.
To improve the sound insulation, heat insulation, and noise reduction effects of automotive interiors, nonwoven composite technology combines two fabrics of the same or different qualities. Composite nonwoven fabrics are more suitable for automotive headliners, interior trim, seat cushions, and other products.
