Sidney S. Locke, Jr. 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).

  • Patent number: 7524551
    Abstract: Certain chemical compositions provide superior repellency, durability, and soil (stain) release properties when applied to a textile or fabric. Compositions may contain a fluorochemical-containing soil release component or a crosslinking component, or both, and also may contain an antimicrobial agent. In some applications, the crosslinking component may be hydrophobic, so as to be generally not compatible with aqueous environments. Compositions having less than about 6 weight percent of a fluorochemical-containing soil release component, based upon the weight of the treating composition, may be employed in some applications.
    Type: Grant
    Filed: October 25, 2007
    Date of Patent: April 28, 2009
    Assignee: Milliken & Company

  • Patent number: 7012033
    Abstract: Wash-durable fluorochemical-containing textile and/or fiber treatments that simultaneously impart soil resistance (or soil-release) properties and moisture wicking characteristics to target fabric substrates are provided. Such treatments surprisingly impart these two simultaneous effects to target fabrics and/or fibers because fluorochemicals generally provide moisture repellency rather than moisture wicking capabilities. As prior soil release/moisture wicking treatments do not function properly, or, alternatively, compromise hand or other properties of certain target textiles after treatment application, a new, effective, soil release/moisture wicking formulation for such purposes was needed. The inventive treatment is extremely durable on such fabric substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its soil release/moisture wicking properties.
