An improved headliner material is formed of two layers formed from two types of polyester fibers. The polyester layers include both binder and non-binder fibers. The binder fibers are provided by an adhesive sheath that melts to secure the binder and non-binder fibers together. The layers are provided with different percentages of binder fibers. One layer is provided with 20% to 30% of binder fibers, with the remainder being non-binder fibers. This layer is less rigid, and provides loft and sound absorption to the headliner material. The other layer is provided with a greater percentage of binder fibers, and preferably, 40% to 60% binder fibers. This layer provides structure and rigidity to the headliner material.

Vehicle headliner formed of polyester fibers

A unique material is disclosed for use in trim panels, such as headliners. The unique material includes a central polyester honeycomb core, and outer polyester layers providing an I-beam construction. In a most preferred embodiment of this invention, the layers are all formed of polyester such that portions trimmed away from the panel are easily recycled. In addition, since the honeycomb core is formed of a thermoplastic, it is easily molded to desired shapes. The honeycomb core provide good strength to weight characteristics and also good acoustic characteristics.
