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.
