What to Do When the Interior Roof Fabric of a Sedan Falls Off?

The interior roof fabric of a sedan can be reattached using polyurethane adhesive. Here is some relevant information about the interior roof fabric of a car: 1. Function: The car roof fabric is an important component of the vehicle's overall roof, primarily serving to enhance the interior decoration. Additionally, the composite fabric of the car roof can improve insulation and heat resistance from the outside, reduce interior noise, and enhance sound absorption. It also improves the comfort and safety of passengers. 2. Material: Textiles account for more than 50% of the materials used in car roof fabrics. Automotive textiles mainly include woven fabrics, knitted fabrics, non-woven fabrics, and fiber composites, with knitted and woven fabrics being the two main categories.
I've also experienced the headliner fabric falling down, which makes annoying flapping noises while driving. The main reason is the aging of the interior adhesive, combined with exposure to high temperatures or humidity causing it to loosen. I once fixed it myself: first, clean the headliner frame with a damp cloth and let it dry completely without leaving moisture. Then use special automotive interior adhesive (3M brand works well), apply a thin, even layer on the back of the fallen fabric. Carefully align and press it back into place, securing the edges firmly. Use wooden clamps to hold it overnight with good ventilation (don't close the doors). This temporary fix can last several months. For large-scale detachment, I recommend going to a repair shop for complete reupholstering - they use professional spray adhesive with heat curing for better durability. For prevention, try to park in shade and regularly dust the headliner with a soft brush to slow adhesive aging.
