Stuffing material of down stems for thermal protection

Abstract

The present invention provides kind of heat-retaining feather wadding. In which feathers have a web piece structure formed by intercrossing and interlinking said feathers, the crossing and linking points of the barbs, tiny barbs, hook of feathers are bonded together by adhesives or textile fibers or chemical textile fibers with low melting point. The present invention provides an even and neat structure, which is tailorable and non-fuzzing. The manufacture process for the heating-retaining feather wadding is simple and efficient. Moreover, The new heat-retaining wadding makes use of big feathers and defective feathers at low cost, it creates a way to use resources more efficient.

1 . A heat-retaining feather wadding comprising feathers having a web piece structure formed by intercrossing and interlinking said feathers, the crossing and linking points of the barbs, tiny barbs, hooks of said feathers are bonded together by adhesives.  
     
     
         2 . The heat-retaining feather wadding of  claim 1  wherein said adhesive is natural resin or polyurethane or polypropylene acid ester or poly-acetate ethyl ester or poly-chlorin ethene or propylene acid emulsion.  
     
     
         3 . The heat-retaining feather wadding of  claim 1  wherein further comprising textile fibers, said feathers and textile fibers having a web piece structure formed by intercrossing and interlinking said feathers with said textile fibers, the barbs, tiny barbs, hooks of said feathers are entangled by said textile fibers.  
     
     
         4 . The heat-retaining feather wadding of  claim 3  wherein said textile fibers is nature textile fibers or synthetic textile fibers or chemical textile fibers.  
     
     
         5 . The heat-retaining feather wadding of  claim 1  wherein further comprising chemical textile fibers with low melting point, said feathers and chemical textile fibers with low melting point having a web piece structure formed by intercrossing and interlinking said feathers with said chemical textile fibers with low melting point, the barbs, tiny barbs, hooks of said feathers are adhered with said chemical textile fibers with low melting point.  
     
     
         6 . The heat-retaining feather wadding of  claim 5  wherein said chemical textile fibers with low melting point is alkali polyester fiber or mixture of Polypropylene fiber and polyethylene fiber or Polypropylene fiber.  
     
     
         7 . The heat-retaining feather wadding of  claim 5  wherein the melting point of said chemical textile fibers with low melting point is from 110° C. to 140° C.  
     
     
         8 . A method for making heat-retaining feather wadding comprising the steps of: 
 using non-weaving textiles technology to intercross and to interlink feathers and textile fibers to become a web piece structure;    entangling the barbs, tiny barbs, and hooks of said feathers with said textile fibers by needles punching.    
     
     
         9 . A method for making heat-retaining feather wadding comprise the steps of: 
 using non-weaving textiles technology to intercross and to interlink feathers and chemical textile fibers with low melting point to become a web piece structure;    pressing said web piece with a temperature in the range of 110° C. to 140° C., said chemical textile fibers with low melting point adhere said feathers together.    
     
     
         10 . The method for making heat-retaining feather wadding of  claim 9  wherein said chemical textile fibers are alkali polyester fibers or mixture of polypropylene fibers and polyethylene fibers or and polypropylene fibers.
