US 2005/0142964 A1 · Composite shoddy and method of manufacturing same

Abstract

The present invention relates to a composite shoddy for use in a vehicle interior. To this end, the composite shoddy of the present invention includes an organic material having a predetermined density defining an organic bottom layer and a scrim material having a predetermined density defining a scrim top layer. The scrim top layer is adapted to operatively engage a surface material and accommodate movement of a surface material in the shear direction. The composite shoddy further includes a mastic material having a predetermined density defining a mastic middle layer. The mastic middle layer is disposed between the organic bottom layer and the scrim top layer.
