Water-repellent resin, water-repellent fabric, and fabricating method thereof

A fabricating method of a water-repellent fabric, comprising:

• performing a first thermal process to mix a polyol, a cross-linking agent, and a choline are reacted to form a first mixture, wherein a reaction temperature of the first thermal process is between 90° C. and 120° C.;
• mixing the first mixture and a water repellent, such that a second mixture is formed, wherein the water repellent comprises a hydroxyl group, an amino group, or combinations thereof;
• dipping a base cloth in the second mixture, such that the second mixture covers the base cloth and infiltrates into the base cloth;
• and
• performing a second thermal process, such that the second mixture is reacted to formed a water-repellent resin, and the water-repellent resin is disposed on the base cloth, wherein a reaction temperature of the second thermal process is between 120° C. and 150° C.
