Abstract
An automotive interior trim part (10) is made by molding a substrate retainer layer (16), forming a skin layer (12) and forming an intermediate layer (14). The intermediate layer (14) is formed from a plurality of clusters of entangled high melt and low melt kinked fibers of polyethylene terephthalate (PET). The PET layer is blown into a partially closed mold that has the skin and retainer positioned in each mold die. The mold undergoes induced vibrations to promote tightening of the packed clusters. The mold is then fully closed to compress the PET fibers into full density. Heated air is then blown into the mold to soften the low melt fibers to adhere them to the retainer layer and skin. Cool air is then blown into the mold to resolidfy the clusters and form the intermediate layer into its molded shape.
