Abstract
Cationic and non-ionic fluorochemicals, mixtures of cationic and non-ionic fluorochemicals, blends of the mixtures with fluorochemical poly(oxyalkylenes), and compositions of the fluorochemicals with hydrocarbon nonionic surfactants are provided. These fluorochemicals and compositions, in dispersions, emulsions and microemulsions, may be applied to porous fibrous substrates to give oil and water repellancy and soil resistance.
