  • Method of making transparent film from multilayer blown microfibers
    Patent number: 5248455
    Abstract: Method of making a transparent film by forming two or more melt streams, combining the melt streams into a multilayer melt stream, extruding the layered melt stream and attenuating with an airstream to form multilayer microfibers, collecting the microfibers as a nonwoven web, and consolidating the web under heat and pressure. At least one of the melt streams is a thermoplastic elastomer and at least one of the melt streams is a thermoplastic material. The transparent web has a generally continuous elastomeric phase with an included array of thermoplastic microfibers.

    Inventors: Eugene G. Joseph, James A. Rustad
  • Film materials based on multi-layer blown microfibers
    Patent number: 5190812
    Abstract: An extensible transparent film is provided having a continuous phase of a low modulus or elastomeric material and an included array of entangled microfibers. The film turns opaque and increases moisture vapor transmission when stretched.
