Abstract
Abstract A method of treating hydrophobic fibrous material to provide both an antistatic and anti-soilant coating which consists of applying to the fibrous material, such as a carpet or rug, a composition containing, as the active ingredient, a condensation product of higher saturated fatty acid and either tetraethylene pentamine or triethylene tetramine.

A hydrophobic fibrous material coated with an antistatic and anti-soilant composition consisting of an antistatically effective amount of an antistatic product which is essentially the condensation product of a fatty acid and an amine, said fatty acid being essentially either stearic acid, palmitic acid or a mixture of stearic and palmitic acids, and said amine being either tetraethylene pentamine or triethylene tetramine, the mol ratio of the fatty acid to the amine being about 1.5 to 1.
