Abstract:

An automotive tufted carpet with improved acoustic properties is formed with a two-part primary backing. The first backing layer is formed of a woven or non-woven material, and the second backing layer is formed of a microfilament spunlaced material possessing sound absorbing acoustic properties. The first backing layer and second backing layer are thermobonded together with an adhesive web positioned therebetween to form the two-part primary backing. Tufts of yarn are then sewn through the two-part primary backing. The resulting acoustically enhanced automotive tufted carpet may be backcoated or precoated, and may have a secondary backing adhered thereto as a matter of choice.
