  • Treated textiles
    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
    Inventors: Xinggao Fang, Sidney S. Locke, Jr., Paul A. Maclure, Jason G. Chay, Michelle Purdy

  • Compositions and methods for treating a textile using such compositions
    Patent number: 7244371
    Abstract: Certain compositions provide excellent repellency, durability, and soil/stain release properties when applied to a textile or fabric. Such compositions may include: a repellent component, a hydrophilic resin component, a soil release component; and a crosslinking component. A method for applying such compositions to textiles also is disclosed.
