Stretchable sweatband for a cap

Abstract

A sweatband used for headwear that is woven of 100% combustible synthetic yarn without any polyurethane. The sweatband provides excellent sweat absorbing capability and exhibits good elasticity through the structure of the textile without imposing undue pressure on the wearer so that the sweatband may be worn comfortably for a long period of time. The yarn used to produce the sweatband is passed through a bulky process, being shrunk through a low temperature short-term combustion method and dry heat treatment process after weaving. The sweatband preferably has a unitary, single ply construction that is planar and does not twist in the absence of elongating force.

1 . A stretchable sweatband for headwear, said sweatband woven with 100% nylon combustible synthetic yarn that contains no polyurethane.  
   
   
       2 . The sweatband as set forth in  claim 1 , wherein said sweatband is formed as a single unit body without additional stitch work for connection to headwear.  
   
   
       3 . The sweatband as set forth in  claim 2 , wherein said sweatband has a file-shaped planar construction that does not twist in a middle portion thereof.  
   
   
       4 . The sweatband as set forth in  claim 1 , wherein the sweatband is single ply.  
   
   
       5 . The sweatband as set forth in  claim 1 , wherein the sweatband is two-ply.  
   
   
       6 . Headwear comprising: 
 a crown main body;    a visor portion secured to a peripheral edge of said crown main body and extending outwardly therefrom; and    a sweatband woven with 100% nylon combustible synthetic yarn that contains no polyurethane.    
   
   
       7 . The headwear as set forth in  claim 6 , wherein said sweatband is formed as a single unit body without additional stitch work for connection to said crown main body.  
   
   
       8 . The headwear as set forth in  claim 7 , wherein said sweatband has a file-shaped planar construction that does not twist in a middle portion thereof.  
   
   
       9 . The headwear as set forth in  claim 6 , wherein the sweatband is single ply.  
   
   
       10 . The headwear as set forth in  claim 6 , wherein the sweatband is two-ply.  
   
   
       11 . A method for forming a sweatband: 
 weaving 100% nylon combustible synthetic yarn that contains no polyurethane into a unitary body;    processing said yarn by shrinking through a low temperature, short-term combustion method; and    subjecting said yarn to a dry heat treatment process to produce a file-shaped planar sweatband that does not twist in a middle portion thereof.
