Anti-staining resin, anti-staining fabric and fabricating method thereof

A fabricating method of an anti-staining resin, comprising:

• performing a first thermal process to mix a polyol, a cross-linking agent, and a choline, such that a first mixture is formed, wherein a reaction temperature of the first thermal process is between 90° C. and 120° C.;
• mixing the first mixture and a chain extender, such that a second mixture is formed, wherein the chain extender comprises a first reagent and a second reagent;
• 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 formed into an anti-staining resin, and the anti-staining resin is disposed on the base cloth, wherein a reaction temperature of the second thermal process is between 120° C. and 150° C.
