  • Treatment of fibrous substrates with acidic silsesquioxanes emulsions
    Patent number: 6468587
    Abstract: This invention relates to a method for imparting soil-resistant and water-repellent properties to fibrous polyamide substrates (such as carpet fibers) by applying an acidic aqueous treating solution containing a silsesquioxane. This invention also relates to the treating solution used to impart soil resistance, and water repellency to the fibrous polyamide. This invention also relates to treated fibrous substrate made according to the method of this invention.
