  • Method of making a monofilament having on the surface embedded filamentons material
    Patent number: 4810319
    Abstract: A method for effecting the electrostatically enhanced and selectively directed deposition of short lengths of solid filamentous materials onto the surface of a downwardly flowing liquid monofilament in a gaseous environment concurrently with an electrostatically induced accelereated solidification of the surface modified monofilamentous material into self-supporting condition to produce embedded filamentous appendages extending therefrom.
