Method of manufacture of down insulated goods

Abstract

A method of manufacturing insulated goods with down filling, which comprises initially forming packets of a predetermined amount of down compressed into a predetermined size, which packets are placed in compartments for down in the goods. The compartments are completely closed for containing down, and the packet of down in each compartment is then ruptured by striking it, permitting the down to release into the compartment. Subsequent immersion of the down insulated goods in a solvent for the packet material dissolves such material leaving only down in the compartment.

I claim:.]. .Iadd.We claim:.Iaddend. 
     
       1. A method of placing insulating down in a compartment in a garment comprising packaging down in a soluble film packet sealed against the escape of down therefrom; placing said packet in a down compartment in such a garment; securing said compartment closed and into a down-holding compartment; rupturing said packet in said closed compartment to release down therein; and immersing said compartment in a solvent for said soluble film. 
     
     
       2. A method according to claim 1 wherein said down is compressed in said packet. 
     
     
       3. A method according to claim 2 wherein the dimensions of said packet are substantially less than the compartment into which it is placed. 
     
     
       4. A method according to claim 1 wherein said rupturing is caused by striking or tearing said packet. 
     
     
       5. A method according to claim 1 wherein said film is soluble in water and said solvent is water. 
     
     
       6. A method according to claim 5 wherein said film is a polyvinyl alcohol. 
     
     
       7. A method according to claim 5 wherein said film is a water soluble cellulose. 
     
     
       8. A method according to claim 1 wherein said film is soluble in an organic solvent for such film. 
     
     
       9. A method according to claim 8 wherein said film is a polystyrene. 
     
     
       10. A method according to claim 1 wherein said packet is perforated. .Iadd. 11. A method of placing insulating down in a compartment in a garment comprising: Inserting in a down compartment in such a garment a down-containing packet made of a soluble film sealed against escape of down from said packet; securing said compartment closed and into a down-holding compartment; rupturing said packet in said closed compartment to release down therein; and immersing said compartment in a solvent for said soluble film..Iaddend..Iadd. 12.
