When you step into a vehicle, the tactile and visual impression of the interior fabric can influence everything from brand perception to passenger comfort. For decades, automakers have experimented with leather, vinyl, polyester, and nylon—but one material is making a quiet but powerful case in the background: acrylic textile.
Acrylic fabric is an excellent choice for automotive interiors due to its superior UV resistance, thermal insulation, softness, dimensional stability, and ability to retain vibrant color even under extreme conditions. It combines durability with a comfortable tactile feel, making it ideal for seats, panels, headliners, and more.
In fact, leading OEMs in Europe and Japan have increasingly turned to acrylic-polyester blends for sun-exposed interior surfaces after field data showed 20–30% better fade resistance than untreated nylon. One Tier 1 auto parts supplier partnered with SzoneierFabrics to develop a solution-dyed acrylic knit that passed over 1,500 hours of QUV exposure testing—with less than 5% color shift.
So why is acrylic moving from winterwear to steering wheels and side panels? Let’s explore the science and sourcing strategies that make acrylic a growing favorite in the automotive textile world.
What Properties Make Acrylic Textile Suitable for Automotive Interiors?
Acrylic fabric’s suitability for automotive interiors comes from its unique balance of softness, color retention, UV resistance, thermal insulation, and shape stability.
