Claims17
A water- and oil-repellent agent comprising:
- cellulose nanofibers;
- a compound having at least one functional group of an oxazoline group, a carbodiimide group, an epoxy group and an isocyanate group, as a crosslinking agent;
- and
- a perfluoroalkyl compound,
- wherein a perfluoroalkyl group of the perfluoroalkyl compound has 6 or less carbon atoms.
A method for producing a water- and oil-repellent agent, comprising a mixing step of mixing
- cellulose nanofibers,
- a compound having at least one functional group of an oxazoline group, a carbodiimide group, an epoxy group and an isocyanate group, as a crosslinking agent, and
- a perfluoroalkyl compound,
- wherein a perfluoroalkyl group of the perfluoroalkyl compound has 6 or less carbon atoms.
A water- and oil-repellent product comprising a coating layer containing cellulose nanofibers crosslinked by a compound having at least one functional group of an oxazoline group, a carbodiimide group, an epoxy group and an isocyanate group, and a perfluoroalkyl compound, on at least one surface of a substrate having air permeability, wherein a perfluoroalkyl group of the perfluoroalkyl compound has 6 or less carbon atoms.
