    Abstract: A fabric, useful as a primary carpet backing, woven in both the warp and weft directions from filmy elements in the form of longitudinally-oriented, splittable ribbons formed from a blend of a major amount of polyester and a minor amount of a polyolefin. The ribbons split longitudinally when punctured by a tufting needle, thus providing for a more secure grip on the tufted carpet yarn than that given by conventional polyester backings. The use of polyester as a principal component overcomes certain drawbacks of polypropylene backings. Alternative processes for making these fabrics, each involving a heat-treating step at a temperature of at least 150°F (66°C) for a sufficient period of time to render the ribbons splittable, are also disclosed.

    Abstract translation: 可用作主地毯背衬的织物,其以经向和纬向方向从薄膜元件以从主要量的聚酯和少量聚烯烃的共混物形成的以纵向取向的可分裂带形式形成。 当由簇绒针刺穿时,丝带纵向分开,从而提供了与常规聚酯背衬给出的簇绒地毯纱线更牢固的抓地力。 使用聚酯作为主要成分克服了聚丙烯背衬的某些缺陷。 还公开了制备这些织物的替代方法,每种方法涉及在至少150°F(66℃)的温度下的热处理步骤足够长的时间以使带可分开。
