  • Patent number: 4925601
    Abstract: A process for making a melt-blown nonwoven polymeric web for use as a liquid filter medium includes increasing the air (fluid) flow and the forming distance to produce a filter medium that is more bulky and more permeable and therefore resists plugging. The melt-blown process parameters include a polymer through-put between 1.8 and 2.9 PIH, a polymer melt temperature between 530.degree. and 600.degree. F., and air flow rate between 200 and 265 SCFM per square inch, air temperature between 500.degree. and 600.degree. F., forming distance between 12 and 23 inches, and a collector vacuum between 0.5 and 1.0 inch of water.
