A primary carpet backing is provided comprising at least one non-woven layer, wherein the at least one non-woven layer comprises fibers which contact one another at contact zones, wherein the fibers comprise i) first fibers which are manufactured from a first fiber forming polymer, and second fibers which are manufactured from a second fiber forming polymer, or ii) multicomponent fibers which comprise at least a first component manufactured from a first component forming polymer and at least a second component manufactured from a second component forming polymer, characterized in that both the first fiber forming polymer and the first component forming polymer is at least one polyamide, both the second fiber forming polymer and the second component forming polymer is at least one bonding polymer, the first fibers are melt bonded at their contact zones with the second fibers by a solidified melt, or the multicomponent fibers are melt bonded at their contact zones by a solidified melt, and the solidified melt is a solidified melt of the at least one bonding polymer, wherein the bonding polymer is obtained by polymerization of an olefin having a terminal or a non-terminal double bond. Furthermore a tufted backing is provided comprising pile yarns and the primary carpet backing.
