Title: ENHANCED ICE PEEL RESISTANCE / NON-WOVEN MOLDABLE COMPOSITE SYSTEMS WITH ADDED SOUND ACOUSTICAL PROPERTIES
Abstract:
A nonwoven laminate is provided having multi-purposes. One embodiment is an A-layer having a high surface tension factor to prevent water absorption and can be used for fender liners or underbody surfaces of motor vehicles to prevent water from absorbing into the material as well as ice accumulation. The water resistant properties are the result of utilizing a newly engineered hydrophobic PET (H-PET) fiber. Another embodiment, useable alone or in combination with the A-layer is a B-layer that has hollow multi-lobe cross-sectional fibers to provide enhanced sound absorption properties. One or both layers have thermo-moldable characteristics that allow them to be shaped into a specific geometry. In this case, the low melt fibers provided in one or both layers are "fused" and interlock or bridge together to yield a rigid nonwoven water/ice resistant and/or sound absorbing composite.
