Abstract: Microfibers and microfibrillated articles are provided by imparting fluid energy to a surface of a highly oriented, highly crystalline, melt-processed polymeric film. The microfibers and microfibrillated articles are useful as tape backings, filters, thermal and acoustical insulation and as reinforcement fibers for polymers or cast building materials such as concrete.

Abstract: A system for applying a fluid coating onto a substrate includes forming a fluid wetting line by introducing a stream of fluid onto a first side of the substrate along a laterally disposed fluid-substrate contact area. An electrical force is created on the fluid from an electrical field (originating from electrical charges which are on the second side of the substrate) that is substantially at and downstream of the fluid wetting line. The electrical field can be generated by charges that have been transferred to the second side of the substrate from a remote charge generator.

Abstract: A system for applying a fluid coating onto a substrate includes forming a fluid wetting line by introducing a stream of fluid onto a first side of the substrate along a laterally disposed fluid-web contact area. An electrical force is created on the fluid from an effective electrical field originating from a location on the second side of the substrate and at a location substantially at and downstream of the fluid contact area. The electrical field can be generated in a highly effective manner relative to the coating fluid by a sharply defined electrode on the second side of the substrate. Ultrasonics combined with electrostatic fields further enhances coating process conditions and coating uniformity.
