Abstract
A hat capable of recovering the original shape and a method of manufacturing the same are provided. The hat is characterized by preparing mixtures comprising waterborne polyurethane, water, and crosslinking agent; coating synthetic fiber yarns of the hat with the mixture; curing the mixtures in a certain temperature condition in order to form a thin polyurethane film on the surface of fabric or knitted fabric for the hat. The curing reaction products by the waterborne polyurethane component implement a shape recovery of the hat after the deformation or damage due to the external force in the initial shape of the hat.
