Patent 7678717 was granted and assigned to Precision Fabrics Group on March, 2010 by the United States Patent and Trademark Office.
Fabric layers and composite articles that incorporate graphite-containing coatings that do not stain are provided. A fabric layer for use as a flame and heat blocking component of an upholstered article includes intumescent graphite particles that are configured to swell and char in the presence of flame so as to form a barrier to flame, hot gases and heat for a predetermined period of time. The graphite particles have a size greater than about 150 microns which prevents the particles from being drawn to a surface of an upholstered article during sewing and quilting operations.
