Abstract
A fluorochemical treatment composition comprises (a) a sol comprising a colloidal dispersion of substantially discrete, substantially monodisperse in size, polymer-grafted, inorganic microparticles in liquid; and (b) at least one fluorochemical. The composition can be used to impart durable water and oil repellency, stain release, and dry soil resistance to a variety of substrates.
