    Abstract: The carpet backing materials comprise a woven, non-woven or knitted thermoplastic backing fabric, preferably at least partially incorporating polyolefin, in particular polypropylene, yarns, to which a fleece is adhered by means of a hot melt powder adhesive having a softening point below that of the thermoplastic backing fabric. The fleece may, if desired, be pretreated to form a self-supporting web prior to being adhered to the backing fabric. A process for the preparation of the carpet backing materials and tufted carpets incorporating the backing materials are described and exemplified. When incorporated into tufted carpets, the backing fabrics avoid the problem of grinning, and improve tuft locking and dimensional stability of the finished carpets.

    Abstract translation: 地毯背衬材料包括织造的,无纺的或针织的热塑性背衬织物,优选地至少部分地结合聚烯烃,特别是聚丙烯纱线,通过具有低于该软化点的软化点的热熔胶粉末粘合剂粘合羊毛。 的热塑性背衬织物。 如果需要,羊毛可以在被粘附到背衬织物之前被预处理以形成自支撑纤维网。 描述和示例了用于制备包含背衬材料的地毯背衬材料和簇绒地毯的方法。 当装入簇绒地毯时,背衬织物避免了咧嘴笑的问题,并改善了成品地毯的绒头锁定和尺寸稳定性。
