Abstract
A unique headliner includes a pair of spaced polyester fiber mat layers. The polyester fiber layers are preferably felt layers which are needled and consist of a mixture of low and high melt polyester fiber pieces. The low melt fiber pieces are provided with an adhesive sheathing that melts at a low temperature to bond the fiber pieces together. The polyester layers are spaced on opposed side of a polyurethane foam central layer. The combined headliner construction has good strength and acoustic characteristics.
