Electromagnetic Wave Blocking Head Cover

Abstract

An electromagnetic wave blocking head covering includes a head covering body having an electromagnetic wave blocking layer which made by metallic thread or metallic containing foams arranged on an inner or outer side thereof or embedded therein by weaving, stitching or doping techniques for protecting the head of a person against external electromagnetic waves.

1 . An electromagnetic wave blocking head covering, comprising a head covering body having an electromagnetic wave blocking layer joined thereto for protecting wholly or a part of the head of a person against external electromagnetic waves. 
     
     
         2 . The electromagnetic wave blocking head covering as claimed in  claim 1 , wherein said electromagnetic wave blocking layer is formed on an inner or outer side of said head covering body or embedded therein. 
     
     
         3 . The electromagnetic wave blocking head covering as claimed in  claim 2 , wherein said electromagnetic wave blocking layer is a piece of metal-contained cloth, or a piece of metal-contained foam material. 
     
     
         4 . An electromagnetic wave blocking head covering, comprising a head covering body having an electromagnetic wave blocking layer arranged on an inner side or outer side thereof or embedded therein for protecting wholly or a part of the head of a person against external electromagnetic waves. 
     
     
         5 . The electromagnetic wave blocking head covering as claimed in  claim 4 , wherein said electromagnetic wave blocking layer is formed by one of the techniques of weaving, stitching or bonding. 
     
     
         6 . The electromagnetic wave blocking head covering as claimed in  claim 5 , wherein said electromagnetic wave blocking layer is made by weaving metallic threads with cotton threads and synthetic threads, metallic threads with natural threads and synthetic threads, metallic threads with natural threads and synthetic threads, silver threads with natural threads, or silver threads with synthetic threads. 
     
     
         7 . The electromagnetic wave blocking head covering as claimed in  claim 6 , wherein said electromagnetic wave blocking layer is a silk fabric, cotton fabric, knit fabric or wool fabric, or any of a variety of other natural or synthetic fabric doped or coated with a metallic material containing 90%˜50% cotton and 10%˜50% metallic fiber, or 90%˜50% natural fiber and 10%˜50% metallic fiber, or 90%˜50% synthetic fiber and 10%˜50% metallic fiber. 
     
     
         8 . The electromagnetic wave blocking head covering as claimed in  claim 7 , wherein the metallic fiber contained in said electromagnetic wave blocking layer is selected from the group of silver-contained fiber, copper-contained fiber and ferrite-contained fiber. 
     
     
         9 . The electromagnetic wave blocking head covering as claimed in  claim 4 , wherein said electromagnetic wave blocking layer is a metallic material-contained electromagnetic wave blocking layer joined to said head covering body by one of the techniques of weaving, stitching, doping, coating and bonding. 
     
     
         10 . The electromagnetic wave blocking head covering as claimed in  claim 9 , wherein said electromagnetic wave blocking layer is a silver, copper or ferrite-contained electromagnetic wave blocking layer joined to said head covering body by one of the techniques of weaving, stitching, doping, coating and bonding.
