THERMALLY INSULATING STRETCHABLE DOWN FEATHER SHEET AND METHOD OF FABRICATION

摘要

A thermally insulating stretchable down feather sheet and its method of manufacture is described. The core of the sheet is comprised of down feathers mixed with a binder which exhibits elastic properties. The core is sandwiched between a top and bottom stretchable elastomeric sheet having multi¬ directional stretchability. The core down feathers and the binder as well as the elastomeric sheet and bound together by heat treatment to provide a down feather insulating sheet which is stretchable in all directions without fractioning the sheet.
