  • Polymeric integral net
    Publication number: 20010024710
    Abstract: The present invention provides an integral net having a lattice of polymeric material defined by holes traversing the integral net from one surface to the other. The present invention also provides a method for producing an embossed sheet of polymeric material by first contacting a billet of polymeric material with an embossing tool having a plurality of protrusions whereby the embossing tool impresses indentations into the billet to a given depth. Subsequently, the method involves skiving the embossed billet. By this method, an embossed sheet of the polymeric material is removed from the billet, which embossed sheet can be an integral net.

  • Filtration mediam support material and filter comprising same
    Patent number: 5614095
    Abstract: The present invention provides a method of preparing a support for a filtration medium comprising passing a sheet of nonwoven fibrous polymeric material having first and second sides through a calender which comprises a nondeformable roll and a resilient roll, the nondeformable roll being maintained at a temperature below the melting temperature of the material, so as to increase the smoothness of the first side of the material which contacted the resilient roll. A filtration medium support material prepared in accordance with the method of the present invention, as well as a filter comprising a filtration medium and that filtration medium support material, are also provided by the present invention.
