AI Technical Summary
Technical Problem
Conventional polyurethane foam used in vehicle seat padding retains moisture, causing discomfort, contributes to global warming due to high CO2 emissions during production, and is non-recyclable.
Method used
A seat padding made from a 3D entanglement of irregularly arranged fibers with thermoplastic polymers, featuring a flat area formed by ultrasonic welding, which is recyclable, lighter, and allows better breathability and traceability.
Benefits of technology
The new padding material reduces CO2 emissions, provides better comfort through breathability, and enables effective traceability without the drawbacks of polyurethane foam.
