Aus Teilchen bestehende Filterstruktur |
摘要 |
<p>A particulate filter structure and method for making the structure are disclosed. The structure includes a stable framework of relatively large denier fibers having a lower melting component and a higher melting component. The larger denier fibers have a denier of from about 30 dpf or more and are bonded by the lower melting component at the crossover points. Smaller denier fibers, which preferably are of the same composition as the larger denier fibers are immobilized onto the framework formed by the larger denier fibers by applying heat. Functional particulate such as activated carbon is immobilized primarily onto the smaller denier fibers, also by application of heat.</p> |
