Abstract
Insulation and method for making it which bonds fiberfill padding to a membrane is disclosed. Moisture along with heat is transferred from the user of the insulated product to the insulation. The membrane allows the transfer of this moisture to the surrounding air. A novel way of binding polyester padding to a polyester membrane using polyurethane as the adhesive is accomplished by using a solvent to melt the polyurethane.
