    Abstract: A nonwoven primary carpet backing includes thermoplastic polymer filaments or fibers bonded by means of a binder polymer. The backing includes at least a distinguishable thermoplastic woven layer, a distinguishable thermoplastic continuous layer, or a distinguishable nonwoven layer including filaments or fibers bonded by means of a binder polymer, which layer reduces the delamination strength of the backing, measured in accordance with DIN 54310, by at least 30% and preferably by at least 50%, with respect to the same backing without the distinguishable layer. Although the breaking strength of the untufted backing according to the invention is lower than that of untufted backings not including the distinguishable layer, the tufted backing according to the invention actually has a higher breaking strength and elongation than tufted backings not including the distinguishable layer.

    Abstract translation: 非织造初级地毯背衬包括通过粘合剂聚合物粘合的热塑性聚合物长丝或纤维。 背衬包括至少可区别的热塑性编织层,可区分的热塑性连续层或包含通过粘合剂聚合物粘合的长丝或纤维的可区分的非织造层,该层降低了背衬的分层强度,其根据DIN 54310测量 ,相对于没有可区分层的相同背衬,至少30%,优选至少50%。 虽然根据本发明的未脱毛背衬的断裂强度低于不包括可区分层的未起绒背衬的断裂强度,但是根据本发明的簇绒背衬实际上具有比不包括可区分层的簇绒背衬更高的断裂强度和伸长率。
