Abstract: A tufted carpet including a tufted primary carpet backing, pile yarns tufted into the primary carpet backing, a secondary carpet backing adjoining to the primary carpet backing on the side of the primary carpet backing which exhibits backstitches and optionally a precoat and/or a polymer coat, wherein the secondary carpet backing including at least a reinforcement layer of fibers and the secondary carpet backing has an air permeability of at least 1000 l/m2·s, measured according to ISO 9237:1995.

Abstract: A primary carpet backing including a structure of at least three layers, wherein a first layer and a third layer including a nonwoven layer of fibers, and wherein a second layer which includes a reinforcement layer of fibers and is located between the first and the third layer, wherein the nonwoven layer of fibers of the first layer has an air permeability of at most 8000 L/m2·s and the nonwoven layer of fibers of the third layer has an air permeability of at least 1000 L/m2·s measured according to ISO 9237:1995, wherein the nonwoven layer of fibers of the first layer has a lower air permeability as the nonwoven layer of fibers of the third layer.

Abstract: A material including at least one nonwoven layer of fibers is provided comprising textured yarns, preferably knit-deknit yarns. The textured yarns included in the material enables the mechanical properties of the material to be adjusted to enable the material to conform to high local deformations.

Abstract: Proposed is a nonwoven sheeting containing at least one layer of fibers, which at least one layer has a length, a width, and a thickness, which distinguishes itself in that along a direction parallel to its longitudinal direction and/or along a direction parallel to its transverse direction, this layer forms two or more sections, with adjoining sections each exhibiting different mechanical properties. The invention is further directed to the use of the nonwoven sheeting as tufting backing for carpets, carrier for bituminous sheeting, and in irrigation mats, dust control mats, carpet tiles, and secondary carpet backings.
