<p>The invention provides a sheet filter medium having autogenously bonded uncrimped conjugate fibers which contain a polyolefin and another thermoplastic polymer that have different melting points. The filter medium has a density between about 0.07 g/cm3 and about 0.2 g/cm3. The invention additionally provides a three-dimensionally thermoformed filter medium that has a density between about 0.07 g/cm3 and about 0.5 g/cm3.</p> |
