Abstract (en)
Hydrophobizing a collagen fiber containing substrate comprises treating the substrates with at least one carbamoyl sulfonate group containing compound and hydrophobizing the treated substrates in the presence of at least one polysiloxane. An independent claim is included for the collagen fiber containing substrate, preferably leather or furskin tanned with the carbamoyl sulfonate group containing compound and hydrophobized with polysiloxane.
