摘要:
A flooring material having a textile pad substructure with a density of greater than 10 pounds per cubic foot is provided. The textile pad has reinforcement and binding fibers. The binding fibers are thermoplastic and are used to bind the reinforcement fibers together. The pad is created by heating and compressing a fibrous textile batt so that it has a density of greater than 13 pounds per cubic foot.

The invention relates to a motor vehicle part material structure for sound insulation for the motor vehicle interior and motor vehicle trunk, namely floor mats floor coverings, and trunk linings, that makes it possible to industrially implement complete reprocessing of the entire composite, in particular the fiber material. The motor vehicle part has a PIT fiber layer, an optional substrate layer made of PET and/or COPET, an optional PET adhesive layer, a PET adhesive layer, a layer made of PET fiber nonwoven & brie or woven fabric, and an insulating layer made of PET/COPET.

A carpet according to the present invention includes: a first air-impermeable layer (surface layer), a sound absorbent layer provided on a reverse side of the first air-impermeable layer, and a second air-impermeable layer (backing material layer) provided on a reverse side of the sound absorbent layer. In the carpet, a pile yarn is implanted through the first air-impermeable layer and the sound absorbent layer.

摘要:
A process for making a noise absorber carpet including a fabric layer portion and a resinous backing layer portion including the substantially concurrent steps of continuously feeding a softened resinous backing material from a backing resin feeder onto a backing roll to form a continuous resinous backing sheet thereon, and continuously feeding a heated continuous fabric sheet via a fabric roll onto the backing sheet continuously formed on the backing roll, wherein the backing roll includes spike depressions and perforation pins on its surface, and wherein the fabric roll is located close to the backing roll to press the fabric sheet against the backing sheet as the sheets proceed between the rolls and mold spikes and perforations on the backing sheet, the backing roll being cooled to a temperature range between 10 degrees Celsius and 50 degrees Celsius with a cooling medium to harden said spikes and perforations and provide bonding between the fabric sheet and the backing sheet.
摘要:
Light weight acoustic carpet including porous carpeting backed by a primary sound reducing layer and localized secondary insulators for use within vehicles, and methods of making same, are provided. A porous carpet structure including a carpet backing is heated to achieve a fluid or semi-fluid state and then subjected to intense vacuum to draw air through the carpet backing to create a porous structure. A layer of sound absorbing or insulating material may be applied to the porous carpet structure to provide improved acoustic properties. Secondary sound reducing absorbers/insulators may further be included as part of the molding process to provide selected areas of increased thickness and provide tailoring of sound attenuation.
摘要:
A tufted PET carpet assembly and a method of forming the same. The carpet assembly comprising a face layer comprised of polyethylene terephthalate (PET) yarn comprised of PET fibers and tufted at a pre-determined gauge, the face layer having a face weight, a first backing layer adjacent the face layer, and a first back coating layer adjacent the first backing layer. A method of forming a tufted PET carpet assembly with PET yarn comprising the steps of tufting the PET yarn at a pre-determined gauge onto a backing, applying a back coating to the tufted PET via extrusion to lock the tufted PET to the backing, and applying heat to the tufted PET to enhance the look and feel of the PET.
摘要:
Sound attenuating laminates for use within vehicles are provided that include a substrate and polyurethane attached to selected portions of the substrate. The polyurethane is non-porous and serves as a barrier to attenuate sound passing through the substrate. Additional non-porous polyurethane may be added to one or more selected portions of the polyurethane layer to enhance sound attenuation characteristics in the one or more selected portions. Sound attenuating laminates for use within vehicles are provided that include a substrate and breathable polyurethane attached to selected portions of the substrate. The polyurethane serves as an absorber of sound (e.g., sound generated within a vehicle compartment). Additional breathable polyurethane may be added to one or more selected portions of the polyurethane layer to enhance sound absorption characteristics in the one or more selected portions. Porous, breathable carpet assemblies for use in vehicles, are provided and include a substrate and a porous carpet layer with breathable, porous polyurethane sandwiched therebetween. Breathable polyurethane may be applied onto the substrate second surface in one or more areas to enhance sound absorption characteristics of the carpet assembly.

Sound absorbing/sound blocking products, including trim products formed from a porous fibrous layer backed by a sound absorbing layer and a sound blocking layer for use within vehicles, and methods of making same, are provided. A porous fibrous layer structure including a fibrous layer backing is heated to achieve a fluid or semi-fluid state and then subjected to vacuum to draw air through the fibrous layer backing to create a porous structure. A layer of sound absorbing and a layer of sound blocking material may be applied to the porous fibrous layer backing to provide improved acoustic properties. An underlayment may further be included to provide selected areas of increased thickness and provide tailoring of sound attenuation.
