Abstract: A biobased water repellent auxiliary agent and a method of manufacturing the same are provided. The biobased water repellent auxiliary agent includes a molecular complex composed of a polyurethane (PU) dendrimer and a water-based polyurethane dispersion (PUD). The PU dendrimer is formed by polymerizing a trifunctional-group-containing biobased material and an aliphatic linear isocyanate. The water-based PUD includes a monomer derived from the trifunctional-group-containing biobased material, a monomer derived from a cyclic isocyanate, and a monomer derived from a hydrophilic compound. The molecular complex is formed by copolymerizing the PU dendrimer, the trifunctional-group-containing biobased material, the cyclic isocyanate, and the hydrophilic compound.

Abstract: An aqueous polyurethane dispersion and a textile are provided. The aqueous polyurethane dispersion includes water and a bio-based polyurethane. The bio-based polyurethane includes bio-based polyester polyol, hydrophilic polyol, isocyanate, and hydrophilic compound. A weight ratio of the bio-based polyester polyol to the hydrophilic polyol is 2.7:1 to 5.3:1.
