A two-layer secondary carpet backing including a woven scrim layer and a fibrous layer is described. The woven scrim layer is characterized as having a low open area and a flat weave. The two-layer secondary backing is capable of having a non-abrasive, textile back surface. The secondary carpet backing is also capable of having a construction that permits high carpet manufacturing speeds due to high air permeability and is capable of providing high dimensional stability, seam strength, and delamination strength to tufted carpets made therefrom.

L'invention concerne une sous-couche tissée à deux couches comprenant une couche de renfort tissée et une couche fibreuse. La couche de renfort tissée se caractérise par le fait qu'elle présente une surface de vide réduite et un tissage plat. La sous-couche tissée à deux couches peut comprendre une face arrière textile non abrasive. La sous-couche peut également avoir une structure pouvant être obtenue avec des vitesses de fabrication élevées en raison de sa perméabilité élevée à l'air. La sous-couche peut fournir une stabilité dimensionnelle, une résistance de couture, et une résistance au décollement élevées aux tapis touffetés.
