Abstract

A method of processing feathers and products produced thereby. The method preferably comprises the step of reducing feathers in at least one of a refiner and a pulper. A cleaning agent is preferably added to the feather material before and/or after the reducing step. The cleaning agent will preferably be hydrogen peroxide, detergent, a surface acting surfactant, bleach, or a combination thereof. The method can also include the steps of (a) adding paper pulp to the reduced feather material and then (b) forming a product from the combined material.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A method of processing feathers comprising the step of reducing said feathers in a reducing apparatus selected from the group consisting of at least one refiner, at least one pulper, and combinations thereof.  
     
     
         2 . The method of  claim 1  wherein said reducing apparatus comprises a disc mill.  
     
     
         3 . The method of  claim 1  wherein said reducing apparatus comprises a high shear pulper.  
     
     
         4 . The method of  claim 1  further comprising the step of adding a cleaning agent to said feathers.  
     
     
         5 . The method of  claim 4  wherein said cleaning agent is added to said feathers such that said cleaning agent is present with said feathers in said reducing apparatus.  
     
     
         6 . The method of  claim 4  wherein at least a portion of said cleaning agent is added to said feathers after said step of reducing.  
     
     
         7 . The method of  claim 4  wherein said cleaning agent is selected from the group consisting of hydrogen peroxide, detergent, surface acting surfactants, bleach and combinations thereof.  
     
     
         8 . The method of  claim 4  wherein said cleaning agent comprises hydrogen peroxide.  
     
     
         9 . The method of  claim 4  wherein said cleaning agent comprises a detergent.  
     
     
         10 . The method of  claim 1  wherein a reduced feather material is produced in said step of reducing and said method further comprising the step of separating said reduced feather material into a fiber material and a quill material.  
     
     
         11 . The method of  claim 10  wherein said fiber material and said quill material are separated in said step of separating using at least one hydraulic screen.  
     
     
         12 . The method of  claim 10  wherein said fiber material and said quill material are separated in said step of separating using at least one centrifugal cleaner.  
     
     
         13 . The method of  claim 10  further comprising the step of drying said quill material in a high agitation dryer.  
     
     
         14 . The method of  claim 1  wherein a reduced feather material is produced in said step of reducing and wherein said method further comprises the step of adding a bonding agent to at least a portion of said reduced feather material.  
     
     
         15 . The method of  claim 14  further comprising the step of forming a product from said reduced feather material having said bonding agent added thereto.  
     
     
         16 . The method of  claim 1  wherein a reduced feather material is produced in said step of reducing and wherein said method further comprises the step of forming a sheet product from said reduced feather material.  
     
     
         17 . The method of  claim 1  wherein a reduced feather material is produced in said step of reducing and wherein said method further comprises the step of forming a molded product from said reduced feather material.  
     
     
         18 . The method of  claim 1  wherein a reduced feather material is produced in said step of reducing and wherein said method further comprises the step of adding a reduced paper material to at least a portion of said reduced feather material to form a combined reduced material.  
     
     
         19 . The method of  claim 18  further comprising the step of forming a product from said combined reduced material.  
     
     
         20 . The method of  claim 19  wherein said product is formed in said step of forming using a sheeting process.  
     
     
         21 . The method of  claim 19  wherein said product is formed in said step of forming using a molding process.  
     
     
         22 . The method of  claim 21  wherein said molding process uses a vacuum mold.  
     
     
         23 . The method of  claim 18  further comprising the step of adding a bonding agent to at least one of said reduced feather material, said reduced paper material, and said combined reduced material.  
     
     
         24 . A reduced feather product produced by the method of  claim 2 .
