Lawrence E. Blackmon has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Process for forming a yarn having at least one electrically conductive filament by simultaneously cospinning conductive and non-conductive filaments
    Patent number: 5277855
    Abstract: The present invention is directed to a process for forming a yarn having at least one conductive filament wherein the conductive and nonconductive filaments which make up the yarn are simultaneously co-spun. The present process can be performed at spinning speeds of above about 3500 meters per minute to produce a yarn useful in antistatic carpet production.
    Type: Grant
    Filed: October 5, 1992
    Date of Patent: January 11, 1994
    Inventors: Lawrence E. Blackmon, John D. Forster, Walter J. Nunning
  • Process for making spun-like yarn with variable denier filaments
    Patent number: 4414801
    Abstract: A yarn having variable denier filaments with thick and thin regions is drawn at a draw ratio selected to break filaments in the thin regions. This may be done while false-twist texturing. The resulting broken ends protrude from the yarn, giving a spun-like yarn.
    Type: Grant
    Filed: February 9, 1981
    Date of Patent: November 15, 1983
    Assignee: Fiber Industries, Inc.

  • Spun-like yarn
    Patent number: 4351147
    Abstract: A textured continuous filament yarn combining a luxuriant, soft hand with improved moisture wicking for greater comfort in garments. Some filaments have a denier which varies at least 25% (preferably 300-500%), and other filaments have a spiral cross-section.

  • Continuous filament yarn with wool-like hand
    Patent number: 4349604
    Abstract: A yarn for producing fabrics with a wool-like hand, by combining textured filaments with longer filaments preferably of larger average denier. The longer filaments thus protrude in loops from the yarn bundle.
    Type: Grant
    Filed: October 31, 1980
    Date of Patent: September 14, 1982
    Assignee: Fiber Industries, Inc.

  • Method for producing polyester wool-like yarn
    Patent number: 4332758
    Abstract: A yarn for producing fabrics with a wool-like hand, by combining textured filaments with longer filaments preferably of larger average denier. The longer filaments thus protrude in loops from the yarn bundle, and have helical cross-sections.
    Type: Grant

  • Wool-like yarn with moisture transport
    Patent number: 4330591
    Abstract: A yarn for producing fabrics with a wool-like hand, by combining textured filaments with longer filaments preferably of larger average denier. The longer filaments thus protrude in loops from the yarn bundle, and have spiral cross-sections.
