Heat-insulating material and method of making the same

Abstract

The invention relates to a heat-insulating material acceptable for use, such as a bed blanket. The heat-insulating material has a reinforcing layer, a base layer bonded to the reinforcing layer, and flock fibers secured to the exposed surface of the base layer through a discontinuous coating of cured adhesive. The base layer can have a thickness of less than 0.0625 inch. The flock fibers can have a diameter in the range from about 3 denier to about 4 denier. The invention also relates to a method of making the heat-insulating material by providing a laminate of a reinforcing layer and a base layer of a thickness less than 0.0625 inch, wherein the reinforcing layer and the base layer are permanently united to each other; providing an adhesive of a viscosity such that when applied to the exposed surface of the base layer it will remain on the exposed surface without substantial spreading or penetration into the base layer to any substantial depth; depositing the adhesive on the exposed surface of the base layer, with a printing roll having a discontinuous surface, in the form of a discontinuous coating; and distributing flock fibers evenly over the discontinuous adhesive coating before the adhesive sets.
