Abstract (en)
[origin: US4781844A] A textile finishing agent comprising, by weight, about (A) 50-80 parts of an aqueous colloidal suspension, in the form of a sol, at least one of an organosilsesequioxane having units of the formula RSiO3/2 (wherein R is optionally substituted alkyl or aryl of up to 7 carbon atoms) and a cocondensate of a hydrolyzate of a tetraalkoxysilane with an organotrialkoxysilane having RSiO3/2 or SiO2 units, and (B) 20-50 parts of an aqueous dispersion which contains about 5 to 50% by weight of an organic polymer resin which contains perfluoroalkyl groups which have 3 to 20 C atoms and which, in addition to fluorine atoms, can contain at most 1 hydrogen atom or chlorine atom per 2 C atoms and in which the perfluoroalkyl chain can be interrupted by oxygen and which has a fluorine content of about 0.2 to 40% by weight. Textiles finished therewith are hydrophilic, oleophilic and soil resistant.
