Self-Adhering Disposable Headwear Liner

Abstract

A self-adhering, disposable headwear liner assembly having a topsheet layer, an absorbent core layer and a moisture barrier layer non-adhesively joined to each other, and a plurality of straight channels extending through the topsheet layer and the absorbent core layer and extending partially into the moisture barrier layer, wherein the topsheet layer, the absorbent core layer and the moisture barrier layer each comprise fibers and the fibers of adjacent layers are mechanically interlocked to join the topsheet layer to the absorbent core layer and the absorbent core layer to the moisture barrier layer; and an adhesive layer joined to the moisture barrier layer capable of securing the liner to the internal band of headwear.

I claim: 
     
         1 . A self-adhering, disposable headwear liner comprising:
 a topsheet layer joined to an absorbent core layer;   a moisture barrier layer joined to said absorbent core layer;   an adhesive layer joined to said moisture barrier layer; and   a plurality of straight channels extending through said topsheet layer and said absorbent core layer.   
     
     
         2 . The headwear liner of  claim 1 , wherein said straight channels extend partially into said moisture barrier layer. 
     
     
         3 . The headwear liner of  claim 1 , further comprising a release layer removable joined to said adhesive layer. 
     
     
         4 . The headwear liner of  claim 1 , wherein said topsheet layer, said absorbent core layer and said moisture barrier layer are non-adhesively joined. 
     
     
         5 . The headwear liner of  claim 1 , wherein said topsheet layer, said absorbent core layer and said moisture barrier layer are mechanically joined by punch-bonding. 
     
     
         6 . The headwear liner of  claim 1 , wherein said topsheet layer, said absorbent core layer and said moisture barrier layer each comprise fibers and said fibers of adjacent layers are mechanically interlocked to join said topsheet layer to said absorbent core layer and said absorbent core layer to said moisture barrier layer. 
     
     
         7 . The headwear liner of  claim 1 , wherein said channels are cylindrical. 
     
     
         8 . The headwear liner of  claim 1 , wherein said channels are formed by punch-bonding. 
     
     
         9 . The headwear liner of  claim 1 , wherein said moisture barrier layer is joined to said absorbent core layer by an additional adhesive layer. 
     
     
         10 . The headwear liner of  claim 1 , further comprising a carrier layer joined to said adhesive layer and an additional adhesive layer joined to said carrier layer. 
     
     
         11 . The headwear liner of  claim 1 , further comprising hook-and-loop type fasteners, wherein said liner is attachable to itself to form an annular band. 
     
     
         12 . The headwear liner of  claim 1 , wherein said channels are approximately 2 mm to 6 mm in diameter. 
     
     
         13 . A self-adhering, disposable headwear liner comprising:
 a topsheet layer non-adhesively joined to an absorbent core layer;   a moisture barrier layer non-adhesively joined to said absorbent core layer;   an adhesive layer joined to said moisture barrier layer;   a release layer joined to said adhesive layer; and   a plurality of straight channels extending through said topsheet layer and said absorbent core layer and extending partially into said moisture barrier layer.   
     
     
         14 . The headwear liner of  claim 13 , wherein said topsheet layer, said absorbent core layer and said moisture barrier layer are mechanically joined by punch-bonding. 
     
     
         15 . The headwear liner of  claim 13 , wherein said topsheet layer, said absorbent core layer and said moisture barrier layer each comprise fibers and said fibers of adjacent layers are mechanically interlocked to join said topsheet layer to said absorbent core layer and said absorbent core layer to said moisture barrier layer. 
     
     
         16 . The headwear liner of  claim 13 , wherein said channels are cylindrical. 
     
     
         17 . The headwear liner of  claim 13 , wherein said channels are formed by punch-bonding. 
     
     
         18 . The headwear liner of  claim 13 , wherein said channels are approximately 2 mm to 6 mm in diameter. 
     
     
         19 . A self-adhering, disposable headwear liner comprising:
 a topsheet layer non-adhesively joined to an absorbent core layer;   a moisture barrier layer non-adhesively joined to said absorbent core layer;   wherein said topsheet layer, said absorbent core layer and said moisture barrier layer each comprise fibers and said fibers of adjacent layers are mechanically interlocked to join said topsheet layer to said absorbent core layer and said absorbent core layer to said moisture barrier layer;   an adhesive layer joined to said moisture barrier layer;   a release layer joined to said adhesive layer; and   a plurality of straight channels extending through said topsheet layer and said absorbent core layer and extending partially into said moisture barrier layer, wherein said channels are approximately 2 mm to 6 mm in diameter.   
     
     
         20 . The headwear liner of  claim 19 , wherein said topsheet layer, said absorbent core layer and said moisture barrier layer are joined by punch-bonding.
