ABSTRACT:
This invention provides a method of treating fibrous substrates, such as leather, by contacting the substrate with a fluorochemical compound comprising: a fluorochemical oligomeric portion comprising an aliphatic backbone with a plurality of pendant fluoroaliphatic groups, each fluoroaliphatic group having a fully fluorinated terminal group and each independently linked to a carbon atom of the aliphatic backbone through an organic linking group; an aliphatic moiety; and a linking group which links the fluorochemical oligomeric portion to the aliphatic moiety. The fluorochemical compounds provide desirable oil, water and stain repellency to fibrous substrates.
