Abstract: The present invention is directed at fiber compositions for noise abatement and compression resistance for vehicular applications. More particularly, the fiber compositions are suitable to replace expanded polypropylene foam pads utilized in vehicular carpet applications.

Abstract: Steam heating and molding of single or multilayer nonwoven materials, particularly suitable for the formation of three-dimensionally shaped automotive sound insulators.

Abstract: The present invention is directed at electromagnetic shielding that is particularly suitable for applications in electric vehicles. The electromagnetic shielding is relatively lightweight and can be integrated into a carpet or textile type construction.

Abstract: The present invention relates polyester tufted carpet where the tufts are engaged with a primary polyester backing and where a polyester roll coating is applied to the backside of the primary backing to lock the tufts which therefore avoids the use of a latex adhesive. The present invention also relates to the use of a polyester roll coating applied to the backside of a nonwoven polyester carpet.

Abstract: A method of forming a multi-layer needled non-woven article, comprising forming a web of a fiber base layer, an intermediate film and a fiber top layer, wherein the intermediate film is disposed between the fiber base layer and the fiber top layer; needle punching the web with a plurality of needles; and wherein, during needle punching, fibers of the fiber base layer are carried by the needles, extended through perforations in the intermediate film formed by the needles and entangled with fibers of the fiber top layer.

Abstract: The present invention relates to an acoustic composite of non-woven materials, infused with polymeric film material, for automotive applications, and a corresponding method of formation that provides for a relatively broad range of airflow resistance and acoustic performance. Such airflow resistance and/or acoustic performance can be conveniently adjusted by material selection and method of production.

Abstract: The present invention relates polyester tufted carpet where the tufts are engaged with a primary polyester backing and where a polyester extrusion coating is applied to the backside of the primary backing to lock the tufts which therefore avoids the use of a latex adhesive.

Abstract: The present invention is directed at electromagnetic shielding that is particularly suitable for applications in electric vehicles. The electromagnetic shielding is relatively lightweight and can be integrated into a carpet or textile type construction.

Abstract: The present disclosure is directed at the deposition of multiple layers and/or multiple blends of fiber which optionally include other additives in a 3D mold. The resulting parts are particularly suitable for automotive acoustic parts that may be used, for example, in under-carpet applications, flooring, headliners, trunk liners, and inner and outer dash liners. The parts may also include acoustic exterior parts. The fibers may also be filled/packed differently within the mold at any specified location.
