    • A process and method for recycling carpet is disclosed. The process and method involves the liberation and separation of desirable carpet face fibers from the carpet backing materials. The present invention eliminates face fiber shearing. In the present process, the secondary layer of the carpet backing is removed either manually or mechanically. Then, the bottom of the primary backing layer of the carpet with the bottom of the face fiber “U's” exposed, is mechanically grip-abraded by a rubber material. The grip-abrasion of the rubber or rubber-like material across the bottom of the primary carpet backing layer loosens the glue and grips and pulls the face fiber from the primary backing without destructing primary or secondary backing. The liberation and separation of face fibers from the backing materials using this method produces the highest yield of usable materials compared to any other method. It not only separates the entire face fiber for recycling, but it also allows the backing material to be recycled since it is not contaminated with face fibers.
    • 公开了一种回收地毯的方法和方法。 该方法和方法涉及从地毯背衬材料中释放和分离所需的地毯面纤维。 本发明消除了面纤维剪切。 在本方法中,地毯背衬的二层手动或机械地移除。 然后,具有露出的表面纤维“U”的底部的地毯的主要背衬层的底部被橡胶材料机械地抓住。 橡胶或橡胶状材料穿过主地毯背衬层的底部的夹持磨损松开了胶水,并抓住并从主衬里拉动面纤维,而不会破坏初级或次级背衬。 与任何其他方法相比,使用该方法从背衬材料中释放和分离面部纤维产生最高的可用材料产率。 它不仅将整个面纤维分离以进行再循环,而且还可以将背衬材料回收,因为它不会被面部纤维污染。
