Hat with shape-changeable visor or brim

Abstract

According to an embodiment of the present invention, a hat comprises a hat body put on a user's head and a visor externally projecting from the hat body. The visor comprises a pair of upper and lower external layers and a core material formed between the pair of upper and lower external layers. The core material includes a base material formed of polyethylene terephthalate (PET) fabric and a variable resin layer formed by applying a thermoplastic resin having a low melting point onto the base material, The variable resin layer is formed of a low melting point thermoplastic polyester resin with a softening point of 80° C. to 110° C.

What is claimed is: 
     
         1 . A hat, comprising:
 a hat body put on a user's head; and   a visor externally projecting from the hat body, wherein the visor comprises:
 a pair of upper and lower external layers, and 
 a core material formed between the pair of upper and lower external layers, the core material including a base material formed of polyethylene terephthalate (PET) fabric and a variable resin layer formed by applying a thermoplastic resin having a law melting point onto the base material, and wherein the variable resin layer is formed of a low melting point thermoplastic polyester resin with a softening point of 80° C. to 110° C. 
   
     
     
         2 . The hat of  claim 1 , wherein the low melting point thermoplastic polyester resin is prepared by mixing and esterifying terephthalic acid of 100 parts by weight, isophthalic acid of 50 to 75 parts by weight, ethylene glycol of 60 to 75 parts by weight, and diethylene glycol of 3 to 13 parts by weight.
