Embodiment Construction

[0029] The present invention relates generally to vehicle floor systems, deck side trim, optional mats or other interior trim pieces and more particularly to tufted PP carpet or tufted PET carpet and methods of production thereof.

[0030] refer to figure 1 , shows an embodiment of a floor system 1 substantially according to the known prior art. The vehicle floor system 1 comprises three main components, the first being a carpet 2 with a decorative fiber top layer 3, the second being an underlayment 4 and the third being an acoustic and The vibration damping layer 5 of the vibration damping layer. The damping layer 5 is the layer which is in contact with the body shell, the body 6 of the vehicle, which damping layer is generally based on foam and fiber materials.

[0031] The substrate 4 may be an absorber or a barrier layer and may be based on a combination of fibers and foams to form a controlled porous substrate.

[0032] The carpet 2 is formed of two layers, a pile laye...

Abstract

A tufted carpet for use in automotive applications is comprised of a pile layer and at least a primary backing layer. The pile layer has a pile weight and is comprised of a bulked continuous filament (BCF) yarn comprised of a predetermined number of filaments that are of a predetermined diameter. The carpet is tufted at a predetermined gauge. The BCF yarn is consisting of a polypropylene (PP) yarn with a tenacity between 2.6 cN / dtex (centinewton per decitex) and 3.2 cN / dtex at an elongation of 50 % to 70%, or polyethylene terephthalate (PET) with a tenacity between 2.6 cN / dtex to 3.4 cN / dtex at an elongation of 20 % to 40%.

Description

technical field [0001] The present invention relates generally to tufted carpets, and more particularly to tufted carpets for automotive applications. Background technique [0002] In the automotive industry, tufted carpets are used for a variety of purposes and in a wide variety of applications. One such purpose is noise attenuation. Another purpose is to increase the comfort of the driving environment. These objectives are achieved by the vehicle floor system, the main floor, the trunk mid-panel side trim including the cargo floor and the luggage rack. [0003] Those applications can be found in human transportation vehicles such as cars, vans or trucks. A vehicle floor system consists of several layers: a surface layer or fleece layer, a primary backing layer, a back coat layer, a backing layer, and a decoupler. The damping layer is the layer in contact with the Body-in-White (BIW), and its function is to reduce any noise or vibration from the cabin in the BIW. The d...
