Thomas Lehotkay 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).

  • TEXTILE SHEET MATERIAL
    Publication number: 20240026583
    Abstract: A process for producing textile fabrics by applying one or more binder compositions to fibers is provided. The binder compositions include one or more polysaccharides and one or more polymers of vinyl acetate. The polymers of vinyl acetate are based on vinyl acetate to an extent of 50% to 90% by weight based on the total weight of the polymers of vinyl acetate.

  • Textile structures comprising organopolysiloxane polyurea-polyurethane block copolymer
    Patent number: 6815069
    Abstract: Textile structures comprise fibers and an organopolysiloxane-polyurea-polyurethane block copolymer (A) of the general formula (1) as a coating material or finishing material for fibers where R is a hydrocarbyl group, X is an alkylene group, A and Z are oxygen or primary or secondary amino groups, Y is a divalent hydrocarbyl group, D is an alkylene group, and Q is an end group, 1≦n≦4000, a≧1, 0≦b≦40, O≦C≦30, and d>O. The textile structures exhibit excellent hand, waterproofness, and water vapor permeability, and are stable to lanudering.
