Abstract
A method of forming a single piece, shaped, down feather thermally insulating article having different thermal insulating sections is described. A mold is formed with a cavity defining a non-uniformed prescribed shape and having sections of different shapes and depths. Down feather clusters or a mixture thereof is mixed with a binding material and is injected into the mold which is then heated with a suitable heat source to cause the binding material to soften and fuse the mixture together. After cooling the mold, there is formed a single piece, shaped, down feather article which is comprised of sections having different thermal insulating values for use in a product where parts of the product provide different thermal insulating properties.
Claims14
A method of forming a single piece, shaped, down feather article having different density sections and to provide different thermal insulating values, said method comprising the steps of:
- (i) forming a mold with a cavity defining a non-uniform prescribed shape with different depth areas;
- (ii) filling said mold with a mixture of down feather clusters or a mixture thereof mixed with a heat reacting binder material by blowing a predetermined quantity of said mixture in said cavity of said mold to totally fill said cavity;
- (iii) heating said mold with a heat source to cause said binder material to soften and fuse with said down feather clusters or a mixture thereof;
- (iv) cooling said mold and removing therefrom a down feather article having said different density sections formed therein.
