Fiber insulation blanket and method of manufacture

Abstract

A fiber blanket formed with a blend of constituent fibers is disclosed. In one disclosed embodiment, a cellulose fiber blanket is formed having a blend of cellulose fibers comprising approximately 85-90% by weight cellulose, resilient fibers comprising approximately 10% by weight, and the balance being adhesive plastic fibers. The fibers are then formed into a blanket having an R-value at least 4.0 per inch.

What is claimed is:  
     
         1 . A fiber blanket formed with a blend of constituent fibers comprising: 
 cellulose fibers comprising approximately 85-90% by weight cellulose;    resilient fibers comprising approximately 10% by weight;    adhesive plastic fibers; and    said constituent fibers being formed into a blanket having an R-value of at least 4.0 per inch.    
     
     
         2 . The blanket of  claim 1 , wherein said blend of constituent fibers comprises a blend by weight of 85% cellulose, 10% resilient fiber and 5% adhesive fiber.  
     
     
         3 . The blanket of  claim 1 , wherein said blend of constituent fibers comprise a blend of 89% cellulose fiber, 9% resilient fiber, and 2% adhesive fiber.  
     
     
         4 . The blanket of  claim 3 , wherein the density of said blanket may be varied from 0.8-1.5 pounds per cubic foot.  
     
     
         5 . The blanket of  claim 1 , wherein said cellulose fibers are treated (are treated) to provide fire retardant properties.  
     
     
         6 . The blanket of  claim 5 , wherein said properties are provided using a liquid additive.  
     
     
         7 . The blanket of  claim 6 , wherein said liquid additive include a liquid borate.  
     
     
         8 . The blanket of  claim 1 , wherein said cellulose fibers are treated to provide mold resistance properties.  
     
     
         9 . The blanket of  claim 8 , wherein said properties are provided using a liquid additive.  
     
     
         10 . The blanket of  claim 9 , wherein said liquid additive include a liquid borate.  
     
     
         11 . The blanket of  claim 1 , wherein said adhesive fibers contain a material permitting heating by induction.  
     
     
         12 . The blanket of  claim 11 , wherein said material comprises carbon.  
     
     
         13 . The blanket of  claim 1 , wherein said adhesive fibers contain an additive permitting dielectric heating.  
     
     
         14 . The blanket of  claim 13 , wherein said additive comprises a compound of the alkyl aryl sulfonate group.  
     
     
         15 . The blanket of  claim 13 , wherein said additive comprises a compound of the alkyl aryl polyester alcohol group.
